INTRODUCTIONANDSPECIALNOTES  
The LINK 2000 is an integrated battery monitor and inverter/charger control. It displays  
the critical information necessary for 12 V or 24 VDC system battery management and  
allowsprecisecontrolofcriticalinverterandchargerfeatures.TheLink2000-Rcomeswith  
an additional manual describing the Ideal Regulator option. The LINK 2000 may be used  
as a stand-alone battery monitor or with the following inverter/chargers:  
FREEDOM 10, 15, 20, 25, and 30  
In order to understand, use, and install the LINK 2000, PLEASE read this manual! It  
is as short as possible and provides important information. For installation, operation,  
or warranty questions, please call Xantrex.  
The following Important Special Notes contain cautions and special considerations that  
mustbeconsideredduringtheinstallationoftheLINK2000.Failuretoreadandfollowthese

The Helping Hand is used to draw your attention to very important sections of this  
manualortoindicateitemsthatmayneedtobechangedthroughtheSETUProutine.Please  
take the time to read these sections.  
1) DO NOT DISCONNECT THE NEGATIVE BATTERY CABLE TO THE  
FREEDOM WITH THE INVERTER OR CHARGER TURNED ON! WHEN  
INSTALLING, CONNECT THE INVERTER CABLES BEFORE PLUGGING  
THE REMOTE CABLE INTO THE LINK 2000. UNPLUG THE REMOTE  
CABLE BEFORE THE FREEDOM INVERTER IS DISCONNECTED FROM  
THE BATTERY.  
2) Turn the ON/OFF switch located on the inverter to the OFF position.  
3) When used in a mixed voltage (12 V and 24 V) system, Battery #1 is the battery that the  
LINK2000usesforvoltageregulation.Makesureitisthebatterythatisusedbytheinverter/  
charger, or with the alternator regulator option it must be the battery being charged by the  
alternator. See Functions Mode F11 on page 13.

VOLTS  
WhentheVOLTS switchispressed, thevoltageoftheselectedbatteryisdisplayed.  
The measurement range is from 8.5 V to 50 V. The resolution is 0.05 volts. See page 39  
for power supply specification.  
AMPS  
When the AMPS switch is pressed, the current flowing into or out of the selected  
battery is displayed. Amps being consumed are displayed as a negative number. Charging  
amps are displayed as a positive number (no sign). The resolution below 42 amps is 0.1  
amps. Above 42 amps the resolution is 1 amp. The range is from -500 A to 500 A. Over-  
range is indicated by OL.  
Ahrs  
When the A hrs switch is pressed, the amp hours (Ah) consumed from the battery  
isdisplayedasanegativenumber.Duringdischargethenegativenumberwillgrowasamp  
hoursareconsumedandthemetercountsdown.Duringcharging,thenumberofamphours  
consumed will decrease as the meter counts back up toward zero. The range is + 9,999Ah.  
If the battery continues to be charged after the meter counts back up to zero,  
overcharge amp hours are accumulated and displayed as a positive number. If there is an  
accumulatedpositivenumberinthedisplaywhendischarging begins,themeterautomati-  
cally resets to zero and begins counting down. See Overcharge Amp Hours on page 16.  
The meter also automatically resets to zero after a discharge/charge cycle that  
satisfies the conditions for a recalculation of the Charge Efficiency Factor (CEF). In other  
words, if the battery is discharged 10% and then recharged until the charged parameters  
have been met, the amp hours consumed display is reset to zero.  
TIME  
When the TIME switch is pressed, the time which the load can continue to be run  
is displayed. The display is in hours with 0.1 hours resolution. The unit may be set up to  
calculatethetimeremainingbasedontheinstantaneouscurrent, orarollingaverageofthe  
last4,16,or32minutes.Thetimeremainingfunctionalsotakesintoaccountthemagnitude  
of the discharge current (see pages 24–27). The maximum time remaining is 255 hours.  
If you see this display, it means that the current being consumed could be supplied for  
more than 255 hours. During charging, current is a positive (unsigned) number and the  
4
 
Time remaining display reads C C C.  
For the TIME function to operate correctly you must enter your BATTERY  
CAPACITY through the SETUP routine (see page 9). You must also set up the correct  
PEUKERT'S EXPONENT (see page 13). It is also affected by your selection of  
DISCHARGE FLOOR (see page 14).  
Caution: The TIME display is an estimate of how long your battery can sustain a  
load. Wild variations in battery current, battery condition, erroneously declared battery  
capacity, Peukert's exponent, temperature, or discharge floor, and prior charge and dis-  
charge history may affect the accuracy of this estimate. Please use this display only as a  
guide. The LINK 2000 provides you with several important battery parameters. Using  
all of them, including voltage, current, amp hours consumed, and time remaining, allows  
you to know about the state-of-charge of your battery. Do not rely on a single value to  
determine battery status or performance.  
LO BAT  
When50%ofthedeclaredcapacityofeitherBattery#1or#2isconsumed, LOBAT  
flashes in the upper left hand corner of the display. (This indicator is affected by both the  
declared battery capacity and the discharge floor setting.)  
INVERTER/CHARGERFUNCTIONS  
INVERT  
When the INVERT switch is pressed, the inverter is  
enabledandtheGreenLEDislit.Theinverterwillonlyprovide  
output if it is hooked up to the battery and there is no external  
AC power available. The inverter ON indicator does not  
indicateactualoperation,onlythattheinverterisenabled.The  
initial power-up condition is with the inverter turned OFF.  
CHARGE  
When the CHARGE switch is pressed, the charging  
function of the Freedom Inverter/Charger is enabled. The  
GreenLEDislitwhenthechargerisenabled.Theinitialpower-  
upconditioniswiththechargerenabled.Thechargerwillonly

MARINE AND RV OPERATING TIP  
When utility power is available, any loads normally supplied by the inverter are  
automaticallytransferredtoutilitypowerthroughtheinternaltransferswitch.Whenutility  
power is not available the loads run on stored energy in the battery. If you have a load such  
asanelectricspaceheaterrunningonacircuitthatisautomaticallytransferred,yourunthe  
risk of deeply discharging your battery if there is a utility blackout. To avoid this, turn the  
inverterfunctionOFFwhenleavingtheboatorRVunattended.Leavingthechargerfunction

STATUS LINE  
There are four LED status indicators to show the presence of AC power and the charger's  
cycle state.  
AC IN:  
Green LED on when AC is present.  
CHARGE:  
Red LED on when charger is in Charge mode.  
Flashes Red when charger is in Equalize mode.  
Orange LED on when charger is in Acceptance mode.  
Green LED on when charger is in Float mode.  
ACCEPT:  
FLOAT:  
STARTING AND STOPPING EQUALIZE  
The Equalize Cycle conditions the battery with a controlled overcharge to remove  
Lead Sulfate that is not removed during normal charging. Liquid batteries should be  
Equalized every 30 days when in cycling service.  
CAUTION! Turn off voltage sensitive DC loads before equalizing battery!  
DC Voltage from the charger may go to 17 VDC (34 V for 24 V system) during  
equalizing !  
Charge batteries fully before equalizing. To start the Equalize Cycle, first be sure  
that the Charger is ON, then press the SETUP BUTTON for five seconds until the LED  
begins to flash. Now press both the VOLTS and the A hrs BUTTONS simultaneously.  
Hold them both down for five seconds, until the Red CHARGE LED begins to flash,  
and the "E" in the display goes away.  
To terminate the Equalize Cycle and force the charger into the Float mode, repeat  
the same procedure as above. The cycle automatically terminates after eight hours, or if  
AC power is interrupted.  
Equalizing causes the battery to gas. You should check your battery electrolyte  
before and after equalization. Do not overfill before equalization as the electrolyte may  
expand enough to cause it to flow over the tops. You should be present during this type  
of charging. Make sure there is adequate ventilation. Leave the filler caps on or cover the  
tops with a folded paper towel. Terminate the cycle if a battery starts to overflow or  
overheat.  
Gelled batteries are not normally equalized. However, if they have been severely  
discharged, it may be the only way to get them to begin to accept a charge. The voltage  
is limited to the Accept charging level but the cycle lasts for 8 hours. Be sure that the  
battery TYPE # is set to #1 or #2 before using this cycle on gelled batteries (or #3 for  
AGM type batteries).  
Note: Equalizing voltages for Type #1, #2, and #3 batteries is limited to the  
acceptance voltage for the respective battery type.

INVERTERSETUP  
IDLE MODE: The default value is 4 watts. This means it takes a 4-watt AC load  
to turn the inverter on from its low power idle mode. Setting a value of 0 watts means the  
inverter is always on. The low power idle current is about 0.25 amps. When idle mode is  
set to 0 W the current consumption goes up to about 0.9 amps. Range = 0 W, 4 W, 6 W,  
15 W. (0–15 watts in 5-watt steps in Series 458 units.)  
SETUP EXAMPLE: To set the IDLE MODE to 0 watts, first select the INVERT  
on, then press the SETUP BUTTON until the Green LED begins to flash. Now, press and  
hold the IDLE MODE BUTTON. The present value will appear. The display will scroll  
afterthreeseconds.Holdthebuttondownuntil0appears.Releasethebutton.Thenewvalue  
will remain in the display for about five seconds. When the display reverts to the normal  
monitoringfunctionthenewvalueisstoredinnonvolatilememory. Toseeifthenewvalue  
has been successfully stored, repeat the setup procedure but do not scroll to a new value.  
PWR SHARE: The default value is 30 amps (or OFF for Freedom 25). The  
power sharing feature automatically reduces the charger output, and therefore the AC  
power consumption, if the load passing through the inverter's automatic transfer switch  
exceeds the setup value. This load management feature helps prevent AC supply breakers  
from tripping when boats or RVs are plugged into AC power and the charger, water  
heater, and perhaps other loads all come on at once. In "Off Grid" applications the  
auxiliary generator often has several jobs—water pumping, running the washing machine,  
or heavy power tools—in addition to supplemental battery charging. With Power Sharing,  
when a heavy load turns on, it reduces charger output to help supply the heavy load. The  
ranges below are for units with serial numbers greater than 100,000:  
Freedom 10, 15 & 20 Range = 5, 15, 20, 30 A; Freedom 25 & 30 Range = 5, 20, 30 A, OFF;  
Freedom 10E & 20E Range = 2, 5, 10, 15 A; Freedom 25E Range = 2, 10, 15 A, OFF  
For Freedom serial numbers below 100,000 use this table to interpret the display.

ANOTHER SETUP EXAMPLE: To set PWR SHARE to 20 amps on a F10  
Model with a serial number below 100,000, first select the CHARGE on, then press the  
SETUP BUTTON until the green LED begins to flash. Now, press and hold the PWR  
SHARE BUTTON. The present value will appear. The display will scroll after three  
seconds. Hold the button down until 1 appears (see table above). Release the button. The  
new value will remain in the display for about 5 seconds. When the display reverts to the  
normal monitoring function the new value is stored in nonvolatile memory.

MONITORSETUP  
Normally the only MONITOR SETUP parameter that must be changed is BATT  
CAP (see bottom of this page). Please read the section on selecting charged parameters  
(page 21–22) before changing CHARGED V or CHARGED % default values. (See  
FUNC SETUP on page 10 for other system values that may need to be changed.)  
Setting the following parameters only affects the operation of the monitor, mean-  
ing that changing the Charged V parameter does not change the voltage set point of the  
charger in the FREEDOM Inverter/Charger. It only sets the point at which the monitor  
considers the battery full. To change the charging voltage during the Acceptance and  
Float cycles use Ambient Temp. Setup routine. Note also that when the FREEDOM is  
the charging source, the Charged % is always 2%.  
SELECT BATTERY #1 OR #2: To set up a battery parameter, press the button  
for the battery you wish to set up. The LED will light. Do this first as setup changes are  
only made to the selected battery.  
CHARGED V: The ability to set up a Charged Voltage above which the monitor  
considers the battery full allows it to be used with any charging system or battery chem-  
istry. The default Charged Voltage is 13.2 volts for 12-volt systems and 26.4 volts for 24-  
volt systems. The LINK 2000 automatically selects the correct value based on the  
voltage it senses. (If the Alternative Energy function F05 is ON, the default value is 13.5  
volts or 27.0 volts. See FUNCTIONS SETUP, page 10, for details.)  
To change CHARGED V follow the same procedure as described previously:  
Select the battery to be set up. Press SETUP until the LED begins to flash. Then release  
the button, and press CHARGED V until the desired voltage appears and then release  
the button. The new charged voltage is stored in nonvolatile memory. If the charged  
voltage is inappropriate for the sensed battery voltage, Error E14 is displayed (see Error  
Codes and Troubleshooting, pages 28–29). Be sure to read the section on selecting  
correct charged parameters (pages 21–22) before changing the charged voltage.  
CHARGED %: The default value is 2%. This means that the charging current  
(amps) flowing into the battery must fall below 2% of the declared battery capacity  
before the meter considers the battery full. For example, using the default values of 2%  
and 200 Ah means the current must fall below: 4 amps = 2% x 200 Ah.  
Before changing the CHARGED % from either of these values, be absolutely  
sure you understand the section on selecting charged parameters (page 21–22). Setup  
and storage to nonvolatile memory is the same as for the function above.  
BATT CAP: The default value is 200 Ah. The battery capacity must be set  
up if it varies significantly (10–20%) from the default. The battery capacity is used in the  
calculation to determine when the battery is full and in the TIME remaining function.  
To change the battery capacity, press SETUP until the LED begins to flash, then  
release the button. Now press BATT CAP. Scroll until the desired battery capacity is in  
the display. If you are unsure of your battery capacity you may first test it as described  
on page 17. The battery capacity is stored in nonvolatile memory. If you change to a  
different capacity battery you must change this number. Range = 20–2000 Ah in 20 Ah  
increments.

FUNCTIONS SETUP  
FUNC: The FUNC (Function) mode is used to set up  
special functions or features that are not commonly  
changed. They might be thought of as internal software  
switches that allow the selection of special functions,  
or values that, once set, are seldom changed.  
Normally the only functions that must be changed  
are F02 Battery Type, F03 Ambient Battery Tempera-  
ture, and F08 Peukert's Exponent. (See page 9 for how  
to set battery capacity.)  
The setup process for functions is slightly different because the FUNC button is  
used first to scroll to the function to be set up, and then to scroll through the values for  
that function. To access the FUNC mode:  
1) Press and hold the SETUP button until the green LED begins to slowly flash, then  
release the button.  
2) Now press the (blue) FUNC button. The letters ꢀ01 will appear in the display and  
the FUNC LED will begin flashing, indicating you are in the FUNC mode.  
3) Scroll to the function to be set up by holding down the FUNC button.  
4) Release the FUNC button and wait for the current value of the function you have  
selected to appear in the display. This will take about three seconds.  
5) Press the FUNC button now and the display will scroll through the range of values.  
Stop scrolling when the value you wish appears in the display.  
6) If you wish to continue to set up other functions, press the SETUP button until the  
green LED by the FUNC button stops flashing. You may now choose any blue key to  
continue setting up the LINK 2000. If you press the FUNC button again the process  
will begin at the next function after the one you last set up. Whatever functions you have  
set up will become active when the display reverts to its normal mode.  
FUNCTIONS TABLE  
F01 - AVERAGE PERIOD FOR TIME REMAINING CALCULATION  
0 = INSTANTANEOUS (DEFAULT)  
1 = 4-MINUTE AVERAGE  
2 = 16-MINUTE AVERAGE  
3 = 32-MINUTE AVERAGE  
There are four averaging periods that the LINK 2000 can use to calculate the time  
of operation remaining. You may select present consumption level (instantaneous), a  
four-minute rolling average, a 16-minute, or a 32-minute rolling average. Which method is  
best for you depends on your installation. Most installations will find the instantaneous  
or the four-minute average appropriate.  
Operating Tip: Use the longest period of time you can to ensure long term load  
variations are considered. If you want instant feedback, use the instantaneous display  
(no averaging) "0" display.  
10  
 
F02 - BATTERY TYPE  
0 = LIQUID CELL (DEFAULT)  
2 = GEL CELL (FAST CHARGE)  
1 = GEL CELL (STANDARD)  
3 = AGM (Absorbed Glass Mat)  
This function (Default: Type 0, standard liquid cells) sets the appropriate charge  
and float voltages for the FREEDOM charger (see table below) and sets an appropriate  
Peukert exponent. Gel cell owners may use Type 1 or Type 2, but should consult with  
the battery manufacturer prior to using the more aggressive charging regimen described  
by Type 2. Type 3 sets Acceptance and Float voltages suited to AGM type batteries.  
F03 - VIEW OR SET AMBIENT BATTERY TEMPERATURE  
THIS FUNCTION DEPENDS ON THE SETTING OF F14 (SEE PAGE 14  
)
IF F14 IS ON, F03 VIEWS THE PRESENT BATTERY TEMP. (°F)  
If F14 is ON, charging voltage of the Freedom charger and the Ideal Regulator (if  
using a Link 2000-R) is based on the TEMPERATURE COMPENSATION TABLE  
below. The temperature is displayed until another button is pressed on the Link.  
IF F14 IS OFF, F03 SETS A DECLARED BATTERY TEMP. (°F)  
DEFAULT = 70 °F  
RANGE = 30–120 °F  
STEP = 10 °F  
The default value for ambient temperature is 70 °F. The ambient temperature of the  
battery may be set up to select the appropriate Charge and Float Voltages for the charger.  
The temperature may be selected in 10 °F increments. The setup procedure is the same  
as previously described.  
Setting up a different value should only be done if the battery is at a temperature  
significantly different from 70 °F when they are being charged from the FREEDOM.  
If the batteries are located in a hot engine room, but are not normally charged from the  
FREEDOM when the engine is running, do not adjust the temperature to the engine  
room level. High temperatures are destructive to batteries. If your batteries are regularly  
subjected to temperatures above 100 °F you should relocate them or supply forced fresh  
air ventilation.  
Caution! Do not adjust to extremes unless the battery is normally at that  
temperature. Destructive over- or under-charging may occur. Multiply values by  
2 for 24-volt systems. Voltages are typical, charger regulation + 0.2 volts DC.

F04 - TOGGLE DISPLAY BETWEEN AHR AND KWHR  
DEFAULT OFF = Ah DISPLAY MODE  
ON = Ah/kWh ALTERNATING DISPLAY MODE  
WhenthisfunctionisselectedtheAhrsdisplayalternatesbetweenthenormalamp-  
hour mode and the kilowatt-hour counter that the LINK 2000 uses to determine if 100%  
of the energy consumed from the battery has been returned. A recalculation of the CEF is  
notpermittedunlessthiscounterisgreaterthan0.00kWh.Thiscountercountsdownduring  
discharge and the kilowatt hours consumed are displayed with a negative number. During  
charging it counts back up with 100% efficiency. Not allowing a recalculation of the CEF  
and an Ah reset until a positive number is in the counter ensures that there will not be  
a premature reset. See page 21 for conditions required for a recalculation of the CEF and  
an Ah reset.  
F05 - ALTERNATIVE ENERGY MODE  
DEFAULT: OFF  
ON = USE ALTERNATIVE ENERGY DEFAULTS  
Turn this mode on if your Link 2000 is used in Alternative Energy Systems.  
This function 1) reduces the time necessary to satisfy the charged parameters from five  
minutes to one minute; 2) sets Batt #2 discharge floor to 100%; 3) prevents Batt #2 from  
doing Ah resets; 4) changes Charged V parameter to 13.5 V (27 V). If you're using a semi-  
mechanical photovoltaic controller, we strongly suggest you also consider changing  
Charged Current to 4%.  
F06 - MANUALLY SET CEF (NOT RECOMMENDED)  
DEFAULT OFF = AUTO RECALCULATION OF CEF  
DISPLAY = A87 OR A90 (DEPENDS ON BATTERY TYPE)  
RANGE = 65–99 STEP = 1  
Allows manual set up of CEF (Charge Efficiency Factor). Default display A87 or  
A90(dependingonbatterytypeselected—seeF02)indicatesautomaticCEFrecalculation  
feature. Returning to A87or A90from a user CEF restores the automatic CEF feature.  
If a user-setup CEF has been selected it will appear as a U##( Upreceding a number) in  
the DATA mode—see page 15. A different CEF may be set up for each battery; only the  
selected battery's CEF will be changed.  
F07 - SET TEMPERATURE COEFFICIENT  
DEFAULT = 0.5  
RANGE = 0.1–0.9  
STEP = 0.1  
Thisfactorcompensatesforcapacitychangewithtemperature. Typicalvalue 0.5%  
Capacity/°C. This coefficient must be supplied by the battery manufacturer. The default  
value is typical for lead acid liquid or gelled batteries. Normally this value is not changed.  
12  
 
F08 - SET PEUKERT'S EXPONENT  
DEFAULT = 1.25 RANGE = 1.00–1.50  
STEP = 0.01  
Sets the exponent for Peukert’s equation. A setting of 1.00 defeats Peukert's  
calculation. See pages 24–27 for a discussion of Peukert's equation and typical values for  
various batteries. Properly setting Peukert's exponent ensures a more accurate display of  
timeremainingandpercentremaining.  
F09 - Ah OR RATE COMPENSATED % REMAINING MODE  
DEFAULT OFF = Ah DISPLAY MODE  
ON = RATE COMPENSATED PERCENT REMAINING MODE  
Changes the A hrs function to % Remaining mode, which displays the selected  
battery's rate compensated state-of-charge as a percentage of the declared capacity. A full  
battery is displayed as P100 and a 50% charged battery is displayed as P050. When in  
this mode, the battery capacity and Peukert exponent must be accurately set up.  
This option is not available when F04 or F05 is ON.  
F10 - ALTERNATOR CURRENT LIMIT  
DEFAULT = 100  
RANGE = 30–220 AMPS, OFF  
STEP=10AMPS  
This function is only used with the Alternator Regulator Model (Link 2000-R). It  
sets a safety current limit for the alternator. This limits the maximum amount of current  
thatthealternatorcaneverdeliverwhichinturnreducesheatandwearonbeltsandbearings.  
The OFF position turns alternator current limiting off.  
F11 - BATTERY #2 USED FOR CONTROL  
DEFAULT ON = BATTERY #2 USED FOR CONTROL  
OFF = BATTERY #2 IS NOT USED FOR CONTROL  
This function is used to defeat Battery #2 as a part of the charger control function  
oftheFREEDOM inverter(alsoalternatorcontrolintheLink2000-R). Thisisnecessary  
for systems that have both 12 V and 24 V batteries. Battery #1 must be the battery that is  
used by the FREEDOM. You may also wish to use this function if the main house battery  
(Bank1)issubstantiallylargerthanaseparateenginebattery(Bank2)thatisalsomonitored  
by the LINK 2000. This will prevent the LINK 2000 from making a premature transition  
to float based on the smaller engine battery meeting the charged parameters substantially  
before the house battery.  
NOTE: This function is not changed in a reset to factory default values. If you  
wish to change this function you must use the setup routine to change it.  
F12 - BACKLIGHTING INTENSITY CONTROL  
DEFAULT = 130  
This function may be used to increase or decrease the intensity of the backlighting  
for the display.  
RANGE = 0–240

F13 SET DISCHARGE FLOOR  
DEFAULT = 100% RANGE = 50%–100%  
STEP = 5%  
When this option is activated, you may set a discharge floor for each battery bank.

You may wish to set a higher discharge floor, such as 50%, for an engine starting bank and  
a deeper floor, such as 75%, for a deep-cycling house bank.  
F14 - ACTIVE TEMPERATURE COMPENSATION ON, OFF  
DEFAULT = OFF  
RANGE = OFF, ON  
When this function is ON, the Link 2000/Link 2000-R uses the actual battery  
temperature reported from the Freedom Inverter/Charger through the temperature probe.  
IftheunitInverter/Chargerdoesnotreportavalidtemperaturereading, theLink2000will

DATA MODE  
DATA: The DATA mode is used to recall key  
historical information about the battery (battery  
banks).  
To access the DATA mode:  
1) Select Battery #1 or #2 to review its data.  
2) Press and hold the SETUP button until the green LED begins to flash then release the  
button.  
3) Now press the (blue) DATA button. Each time you press the DATA button a new  
piece of data is displayed. You may also hold the button down to scroll through the  
following data:  
CEF (Displayed as EXX): The Charging Efficiency Factor (CEF) is displayed. A display  
of E99 indicates a 99% CEF. This number sets the rate at which amp hours are counted  
backupduringcharging.Thisisanamp-hourCEF,notkWhefficiency.The Defaultsetting  
is 87% for Type 0 (Liquid) batteries, 90% for Types 1 & 2 (Gelled) and Type 3 AGM  
batteries. NOTE: If the CEF display has a "u" in front of it, this means the CEF has been  
selected by the user. See Function F06 for details. The CEF of a battery typically remains  
fairlyconstantuntilendoflife.AsuddendropintheCEFindicatestimetoequalize,abattery

#CEF Recalculations (Displayed as +I999): This is the number of times that the battery  
hasbeendischargedmorethan10%andthenrechargeduntiltheChargedParametershave  
been met. May be considered as the number of charge/discharge cycles the meter has  
recorded since its last RESET to factory defaults. This is useful to evaluate the cycling  
performance of your battery system.  
Deepest Discharge (Displayed as -i999): Shows the deepest discharge in amp hours  
recorded by the meter since its last RESET to factory defaults. Very deep discharges  
indicate battery abuse.  
Average Discharge (Displayed as i999): The running average of all discharges as an  
amp-hour value since last RESET to factory defaults. The average discharge level should  
normally be no more than about 50% of declared capacity.

HOW TO USE THE LINK  
CONTROL PANEL  
BATTERY MANAGEMENT PHILOSOPHY:  
Recharge When the Battery is 50% Discharged!  
The LINK 2000 is a guide to the battery's state of charge. Our Mid-Capacity Rule  
saysyoushouldbeginchargingwhenyourLINK2000showsthat50%of batterycapacity  
hasbeenconsumed.InMarineandRVsystems,whicharetryingtominimizechargingtime  
withanenginedrivenalternatororgeneratordrivencharger, thebatteryisnormallycharged  
onlytothe85%level. Thismeansonly35%ofthebatterycapacityisactuallyavailablefor  
use. The Mid-Capacity rule is a very conservative approach to battery use. Occasionally  
dischargingabatterymoredeeplyisperfectlyacceptable.TheMid-Capacityruleisintended  
asadesignandoperatingguidelinetoprovideoptimalbatterylifeandensurethemostenergy  
output from the battery over its life, not a law which must be obeyed without exception.  
We recommend synchronizing your LINK 2000 to the 100% charged level of the  
battery. You should begin recharging when 50% of your battery capacity has been  
consumed. When recharging from an engine-driven alternator or generator  
suppliedbatterychargeryoudonothavetochargeuntilthemeterreads0amphours  
consumed. You may cease charging when the LINK 2000 is displaying that 15% of the  
battery capacity is still consumed. See the example below. When you plug back into AC  
power, or when your Alternative Energy production exceeds demand, the remaining amp  
hours consumed will be replaced.  
MANAGINGATWO-BATTERYSYSTEM  
With a two-batterysystemwerecommendusing battery#1untilyou consume50%  
of its capacity, then switch to battery #2 and use 50% of it. When both batteries are 50%  
discharged it is time to charge. You should never leave either battery partially discharged  
for more than a few days.  
Suppose you have two 200 Ah batteries for a total system capacity of 400 Ah and  
youhavesynchronized yourLINK2000to 100%chargedbatteries.Youwouldusebattery  
#1 until the LINK 2000 showed that you had used 50% (the display would show -100Ah).  
You would then use battery #2 until you had used 50% of it (-100Ah). At this point charge  
both batteries up to about the 85% level (-30 Ah on each). If you have other reasons to  
continue running the engine or plug back into AC power you may continue charging until  
the meter reads zero.  
OVERCHARGE AMP HOURS  
If the battery is 100% charged, and the LINK 2000 is in sync with the batteries,  
overcharge amp hours are displayed as positive. Some accumulation of overcharge amp  
hours is normal and harmless with systems continuously connected to a charger. For  
example: a 100 Ah battery at the Float voltage will normally have less than 0.1 A flowing  
intoit.Thismeansthatamaximumof 2.4Ahofoverchargewouldaccumulateina24hour  
period. Ifyourbatterysystemislargertherewillbeproportionatelymorecurrentflowand  
positive amp-hour accumulation.  
If the charging system is a constant voltage type set at 14.2 volts, as much as one  
amp of current may be flowing all the time after the battery has reached the charged  
16  
 
parameters.The batterywillbegassingandyouwillseeanaccumulationofalargenumber  
of amp hours each day. This is a clear indication that you are destroying your battery by  
overcharging.CheckyourLINK2000beforeturning offachargingsourcetoseethatyou  
have not accumulated too many overcharge amp hours. When discharging begins,  
overcharge amp hours are erased and the LINK 2000 resets to zero.  
Systems that have a Conditioning or Equalization cycle will accumulate a few  
overchargeamphoursduring equalization.ThisisnormalandensuresthattheLINK2000  
stays in sync with the battery state of charge.  
BATTERYCAPACITYTESTING  
Your LINK 2000 can be used to conduct periodic capacity tests that tell you the  
actualamountofenergyyour batteriescanstore.Acapacitytestshouldstartwithabattery  
that has been properly charged and conditioned. The objective is to find the maximum  
availablecapacity.  
Deep-cycle battery capacity is usually based on a 20-hour discharge rate. A 100 Ah  
battery will provide 5 amps for 20 hours. At discharge rates above 5 amps, the battery will  
not supply 100 Ah. For example: If you are drawing 100 amps out of the battery it will last  
less than one half hour. This was discovered in 1897 by a scientist named Peukert and is  
discussed in detail later. You can see the effect in the following table listing approximate  
capacities at different discharge rates.

passed before the battery voltage fell to 10.5 V you can still determine the capacity with  
somearithmetic. Forexample:assumea12Vbatteryratedat100Ah. Applya5-ampload.  
Suppose it only took 10 hours for the voltage to reach 10.5 volts. The LINK 2000 would  
display -50 Ah. This is the 10-hour capacity. Dividing 50 by 89% (10-hour rate) from the  
table above, you determine that the actual 20-hour capacity is 56 amp hours. You could  
repeat the test at 5% of the tested capacity (2.8A) to verify the actual capacity.  
USING YOUR FREEDOM INVERTER  
TOTESTBATTERYCAPACITY  
Yourinvertermakestestingthebatterycapacityeasy.Firstfullycharge(andequalize  
if necessary) the battery to be tested. Use a load like incandescent lights running on the  
inverter whose amperage consumption is 5% or less of the battery capacity. Let the load  
run until the inverter shuts down on low voltage (about 10.2 V). Read the number of amp  
hours that have been consumed from the battery. If it is not close to the expected number,  
use the procedure outlined above to estimate the capacity.  
Caution! Be sure to completely recharge your battery after a discharge test.

IDEALCHARGECURVE  
The LINK 2000 transmits critical battery state of charge information to the  
FREEDOM Inverter/Charger. This enables the charger to conform to our proven Ideal  
Charge Curve with four basic cycles: Charge, Accept, Float, and Equalize. The  
CHARGE cycle supplies full charger output current until the battery reaches the Accept  
charging voltage (14.4 V typically). The ACCEPT cycle continues until the battery is  
acceptingonly asmallamountofcurrent.Thebatteryisnowfull.DuringtheFLOATcycle  
the voltage is lowered to maintain the batteries, without water consumption, for long life.  
TheEQUALIZEcycleallowsforperiodic"equalization"ofliquidelectrolytebatteriesfor  
maximum capacity and life. The batteries should be equalized about every 30 days during  
deep-cycling service.

HOW TO TELL WHEN A BATTERY IS  
FULLY CHARGED  
(CHARGED BATTERY PARAMETERS)  
MULTIPLE STAGE CHARGING SYSTEMS  
If youareusingthechargerintheFREEDOM,thebatteryischargedwhenthesystem  
switches to the Float cycle. If another manufacturer's charging system is being used it  
should be adjusted so the transition from Acceptance Charging to Float will occur when  
thechargingcurrent,attheAcceptanceVoltage(14.4/28.8Vtypically),dropstobelow2%  
ofthebatterycapacity.(SeethedescriptionoftheIdealChargeCurveonthepreviouspage.)  
CONSTANTVOLTAGECHARGINGSYSTEMS  
Constantvoltagechargingsystemshaverestoredas muchchargetoabatteryas they  
can when the voltage reaches the maximum regulation point (a typical 12 V system is set  
at 13.8 V) and the charging current drops to less than 1% of the battery capacity. (It can  
take more than eight hours for a battery to reach this state of charge.) If you are using an  
engine-drivenchargingsystemandtryingtolimitengineruntime,youprobablywillcharge  
only until the current drops to 5% or 10% of capacity. The LINK 2000 should be  
synchronized to whichever of these charge levels is reached in normal operation.  
USINGSPECIFICGRAVITY  
Accurate battery current measurement is necessary to determine the charged  
parameters in the two previous methods. Specific gravity of the battery can also be used  
todetermine thechargelevelofabattery.Regardlessofthechargingsystemused,a battery  
is charged when the specific gravity shows no increase for three hours, when measured at  
half hour intervals. Typical specific gravity @ 77 °F for a fully charged liquid electrolyte  
battery is 1.265 + 0.050.  
CHARGE EFFICIENCY FACTOR (CEF)  
AND HOW IT IS USED  
The CEF determines the rate at which the Link 2000 counts back up during charging  
to compensate for the inefficiencies of the charging process. The CEF has a factory  
default value of 87%. That means the charger must return 1.15 Ah to the system for the  
battery to restore 1.0 Ah.  
The CEF is automatically recalculated (and averaged over the last few cycles) after  
every charge cycle if the battery has been discharged more than 10% of the declared  
battery capacity and the charged parameters for voltage and current (selected automati-  
cally or manually in the setup procedure) are met for five minutes (may vary by setup).  
Additionally, 100% of the kWh removed must be returned during charging.  
Continual CEF compensation ensures that the battery state of charge and the Link  
2000 stay in sync. Monitoring the CEF over time helps assess changes in performance of  
the battery or charging system.

SYNCHRONIZINGYOURLINK2000  
TO A CHARGED BATTERY  
A charged battery has zero Ahrs removed. Synchronizing your LINK 2000 to read  
zerowhenthebatteryischargedensuresthatyoualwaysknowthenetnumberofamphours  
removed. The charged parameters on the previous page indicate when a charging system  
has put as much energy into a battery as it normally can and the battery can be considered  
charged.  
Your LINK 2000 must be synchronized at this point!  
TWO WAYS TO SYNCHRONIZE  
There are two ways to synchronize your LINK 2000 to a battery that has met the  
charged parameters:  
1) Install the LINK 2000 on a charged battery and it will automatically be in sync.  
2) If the LINK 2000 is installed on a partially charged battery, simply charge until  
the charged parameters are met. The LINK 2000 will begin counting up and will display  
chargingamphoursaspositive.When the battery ischarged,turnoffthechargingsource.  
AfterdischargingbeginstheLINK2000automaticallyresetstozero,startscountingdown,  
and is in sync.  
If the LINK 2000 should ever get out of sync with the battery state of charge  
it must be re-synchronized. The best way to do this is to be sure the battery is  
discharged at least 10% of the declared battery capacity and then recharge until  
the charged parameters are met. At this point the meter should automatically reset  
to zero.  
Remember, a battery should be fully charged, and float charged if possible, when  
leaving it for extended periods of time for best battery life. This will automatically ensure  
that the Link 2000 stays in sync. Some things that will cause the Link 2000 to not stay in  
syncare:1)dischargecycleislessthan10%ofbatterycapacity,2)batterynotfullycharged  
to 100%, 3) charged voltage set too high for the charging system, 4) charged current % of  
batterycapacitysettoolowforthechargingsystem,5)batteryisneverchargedlongenough  
for 100% charge.  
MANUALLY RESETTING AMP HOURS TO ZERO  
If you want to manually reset your LINK 2000 amp hours display to zero:  
1) First select the battery you wish to reset.  
2) Press the SETUP button for five seconds. When the LED begins flashing,  
release the button.  
3) Press and hold the RESET A hrs button for three seconds (until the normal  
display returns) to reset the amp hours of the selected battery to zero.  
20  
 
MANUALLYSELECTINGTHECHARGED  
BATTERYPARAMETERS  
DISCUSSION: HOW THE LINK 2000 USES THESE VALUES  
The LINK 2000 allows the setup of specific charged parameters. The factory  
default values have been carefully chosen to work on most systems, including constant  
voltageandmultiplestepchargingsystems.ThefactoryChargedParametersare 13.2volts  
and 4 amps (2% of the default battery capacity of 200 Ah). This means when the battery  
is above 13.2 volts and the current falls below 4 amps, for five minutes, the LINK  
2000 considers the battery full.  
The LINK 2000 learns the Charge Efficiency Factor (CEF) of the battery based on  
the Charged Parameters. A CEF of greater than 100% is not allowed. To trigger a  
recalculation of the CEF, the battery must be discharged at least 10% of declared capacity.  
Afterthisdischarge,atleast100%oftheenergy(kWh)removedmustbereturned,andboth  
the Charged Voltage and Charged Current % parameters must be met for five minutes for  
a recalculation of the CEF to occur. Amp hours consumed are automatically reset to  
zero after a recalculation of the CEF. The new CEF is used during the next recharge  
cycle to determine the rate that the meter counts back up toward zero.  
The battery must go through several cycles for the meter to learn the CEF.  
It will take several (at least six) cycles for the displayed CEF to reflect the actual CEF of  
the battery.  
SHOULD YOU CHANGE THE CHARGED PARAMETERS?  
Pleaseconsiderchangingonlythebatterycapacityunlessyoursystemfallsintoone  
of the following categories:  
1) Battery chemistry other than lead acid.  
If you are using NiCad or other types of batteries you should change your Charged  
Parameters to the factory specification. NiCad systems would normally use 15.5 to 15.7  
astheChargedVoltage.TheChargedCurrent%canprobablystayat2%ofdeclaredbattery  
capacity.  
2) Charging normally ends before the current drops below 2% of battery capacity.  
If the charging system is shut down before the charging current drops below 2%,  
thefactoryChargedCurrent%willhavetobechanged.Examplesmightincludelargesolar  
arrays with controllers that shut off the array at a particular voltage and turn it back on at  
alowervoltage,orengine-drivenalternatororACgeneratorsrunninglargeinverter/chargers  
that are normally shut down before the charging current falls below 2% of capacity.  
Remember,ifchargingisnormallyterminatedwhenthecurrentisahigherpercentage  
of battery capacity, the battery is probably not being thoroughly charged. If the meter  
accumulatesnegativeamphours, itislettingyouknowthatyoumustperiodicallyremove  
them by a complete charge or that you are not meeting the charged parameters.  
21  
 
RULES FOR CHANGING THE  
CHARGEDBATTERYPARAMETERS  
If you must change the Charged Parameters please use the following rules.  
1) The Charged Voltage MUST be at least 0.1 V BELOW the charging system  
voltage.  
2) The Charged Current % times declared Battery Capacity MUST be  
GREATER than the minimum current the charging system maintains the battery at, or  
turns off at.  
If the charged parameters are not correctly selected,  
the LINK 2000 will never recalculate the CEF. For example:  
(1) Ifyourchargingsystemonlyreaches13.8(27.6)volts,aChargedVoltageof14.0(28.0)  
volts will not work—it is set too high and the Link 2000 will never know that the battery  
ischarged.LowertheChargedVoltage.ChangingtheChargedVoltageto13.7(27.5)volts  
should work. See Monitor Setup on page 9.  
(2) If the Charged Current % times the Battery Capacity is less than the current at which  
the charging system switches off, the Charged Current cannot be met and the Link 2000  
willneverknowthatthebatteryischarged.Ifthechargingsystemshutsoffwhenthecurrent  
is 10 amps, using the factory default value of 4 amps (2% of 200 Ah) will not work.  
(Changing the Charged Current % to 6% would give a Charger Current of 12 amps, which  
would work fine. See Monitor Setup on page 9.)  
Ifyouhaveachargingsystemthatcannotsatisfythedefaultvalues,theCEFwillnot  
be recalculated and the meter will use the default CEF of 87%. This will work fine in most  
systems. You may notice an accumulation of negative amp hours. If so, set up appropriate  
chargedparametersorresynchronizeperiodically.(SeeSynchronizingYourLink2000To  
a Charged Battery on page 20.)

RESET / INFO FUNCTIONS  
The drawing below shows the Reset/Info Functions layout. To access these, press  
the SETUP BUTTON for ten seconds. The time is long to avoid unintentionally entering  
this mode. When the green LED begins to flash quickly (about three times per second)  
select the Advanced Function you wish by consulting this drawing. The display returns to  
the monitoring mode five seconds after the selected function button is released.  
# LOW BAT/ # OL: The number of Inverter Low Battery shutdowns (since last reset)  
isdisplayedwithaminussign(negativenumber). ThenumberofInvertershutdowns(since  
last reset) from other causes are displayed with no sign (positive number). The display  
alternates at three-second intervals until the button is released.  
SOFTWARE INFO: The revision number of the LINK 2000 software is displayed.  
FLASH ALL LEDS & SEGMENTS: This display test continues until the button is  
released.  
RESET TO FACTORY DEFAULTS: When this button is held down for five seconds,  
all of the values set up for the selected battery are reset to the factory values. A 0 (zero)  
should appear briefly in the display (watch closely). All historical data is lost! Normally  
this would only be done if you are changing batteries.  
IMPORTANT NOTE! During a RESET TO FACTORY DEFAULTS any  
changes to the inverter/charger setup are also reset to the factory values IF the  
INVERT or CHARGE LEDs are on.  
IMPORTANT NOTE! Function F11 (Battery #2 used for control) is NOT  
reset during a RESET TO FACTORY DEFAULTS.

HIGH DISCHARGE RATES  
& PEUKERT'S EQUATION  
Peukert's Equation describes the effect of different discharge rates on battery  
capacity. As the discharge rate increases the available battery capacity decreases. The  
tables on pages 25, 26 and 27 have typical values of "n" for common batteries. Page 25  
is a look-up table, pages 26 & 27 have "n" values for common batteries, and page 27 has  
the formula for calculating "n" for other batteries.  
The LINK 2000 uses Peukert's equation only for calculating the Time Remaining  
of operation function. The amp hours display is always the actual number of amp hours  
consumed. This means that if you rapidly discharge a battery, your time remaining  
number may show zero hours remaining before you see the total number of amp hours  
of battery capacity consumed.  
If battery Type 0 is selected, the initial Peukert exponent is set at 1.25. This  
is an appropriate mid-range value for many common liquid cells. If any other battery  
type is selected, the initial Peukert exponent is set at 1.11. This is an appropriate  
mid-range value for many common gel and AGM cells. Please note that you may only  
declare one battery type using function F02. This is because we strongly recommend  
against mixing AGM, gel, and liquid electrolyte batteries in the same system. The  
selected Peukert exponent is applied to both battery banks. Set the exponent to the  
correct value for the bank which you use most often.  
Making two discharge tests, one at a high discharge rate and one at a low rate, that  
bracket your normal range of operation allows you to calculate an "n" that will describe  
this varying effect. The Link 2000 uses a default value of "n" equal to 1.25 which is  
typical for many batteries.  
At some low-to-moderate discharge rate, typically a battery's 20-hour rate, the  
logarithmic effect of Peukert's Equation is greatly reduced. The effect of discharge rates  
smaller than this is nearly linear. Battery manufacturer specifications of battery capacity  
in amp hours is typically given at the 20-hour rate. From this description, if a battery is  
discharged at this rate for the period of time called out, you will be able to remove the  
rated capacity.  
The equation for Peukert's Capacity (C ) is:  
p
log t2 - log t1  
n
n =  
C = I t where  
p
log I1 - log I2  
By doing two discharge tests and knowing I1 & I2 (discharge current in amps of  
the two tests), and t1 & t2 (time in hours for the two tests) you can calculate n (the  
Peukert exponent). You will need a calculator that has a Log function to solve the equation  
above. You may also use the 20-hour discharge rate and the number of reserve minutes  
as the two discharges to solve Peukert's equation. See example on page 27. After you  
solve for your Peukert's exponent you may enter it using Function F08.

CALCULATING PEUKERT'S EXPONENT  
Example of using Reserve Minutes @ 25 amps  
and the 20-hour rate to calculate "n".  
First convert Reserve Minutes to hours, then find the discharge current  
at the 20-hour rating. Finally use a calculator to solve the arithmetic.  
Trojan T-105:  
Reserve Minutes = 447 min @ 25 amps.  
t1 = 447 min = 447/60 = 7.45 hrs  
I1 = 25 amps  
20-Hour rating = 225 Ah  
t2 = 20 hours  
I2 = 225 amp hours/20 hours = 11.25 amps  
log t2 - log t1  
log 20 - log 7.45  
log 25 - log 11.25

MICROPROCESSOR RESET PROCEDURE  
The LINK 2000 uses a microprocessor to perform all of its calculations and  
functions. We have worked very hard to ensure a stable, trouble-free product. However,  
likeallcomputerproducts,theunitissometimessusceptibletopowersupplydipsorsurges  
that can cause erratic behavior or memory errors. If you detect a problem, please use the  
following procedure to reset the microprocessor—you may also need to reset the memory  
tothefactorydefaultsasdescribedonthe next page. If you reset to factory defaults besure  
and set up appropriate values for battery capacity, battery type, ambient temperature, and  
Peukert's exponent as previously described. Please read the entire instruction set before  
beginning the procedure.  
TO RESET FROM A LOCKUP, ERRATIC DISPLAY, OR ERRATIC BEHAVIOR  
1)  
2)  
Disconnect from shorepower.  
De-power the meter by removing the fuse from the red wire. If the red wire

can de-power the meter by removing the gray ribbon cable from the monitor  
terminal board and reconnecting it.  
3)  
Wait at least 30 seconds before reconnecting the fuse (or the ribbon cable).  
When the fuse is reconnected use a continuous motion. If the meter is  
intermittently powered and de-powered several times in a short period, the  
microprocessor may lock up.

RESETTING MEMORY TO FACTORY VALUES:  
If some portions of the memory have been "corrupted" you should consider  
resetting to the factory default values and then changing any specific values you need to.  
This ensures a "clean slate" for your new setup.  
1)  
2)  
Follow the procedure outlined on the previous page to first reset the

REQUIREDREADING  
Before wiring the LINK 2000, install the shunt as indicated.  
All wiring should be done before installing the fuses.  
GENERALNOTES  
1) Wiring to the LINK 2000 should be #16 or #18 AWG. (Larger wire is acceptable, but  
not necessary.) Wiring should be per NEC or applicable standards.  
2) The Shunt Sense Leads should be a twisted pair. Leads up to 1,000 feet long may be  
used if they are not run along with other noise-producing conductors. Offset error should  
be less than 0.2 amps.  
Fortheeasiestinstallationyoumaywishtopurchaseourfourtwistedpaircablewith  
thesamecolorcodeasthemeter.Thiscablemayberunbetweenthemeterandthebatteries  
to supply all needed signals. This cable is available from your dealer or from Xantrex.  
Note: You may make your own twisted pair wire by chucking up two wires in an electric  
drill motor and twisting them by running the drill motor until there is a twist every inch. A  
wrap of tape every 16" will keep the wires together and make them easier to pull through  
the raceway.  
3) Caution! If your starter draws more than 500 amps see #5 below.  
CAUTION!!!!  
The output voltage of the shunt is very small. It is critical that all of the  
connections for the shunt sense leads have the highest possible integrity. Every  
effort must be made to prevent corrosion that might affect the sense leads.  
4) Battery current is sensed with a shunt, which is a very precise, small resistance. It is  
insertedinseries(in line)inthenegativewireofthecircuityou wishtomeasure.The current  
is measured by sensing the voltage drop across this resistance. The LINK 2000 uses  
a 50 mV, 500-amp shunt. When 500 amps flows through the shunt, there is a 50 mV drop  
across it. Thus 10 amps equals 1 mV or 1 amp equals 0.1 mV. The display is scaled to read  
amps. If you wish to check this you will need a very accurate digital meter (Fluke 87 in  
4 1/2 digit mode or better) if the current is below 30 amps (3.0 mV). Above 50 amps most  
digital meters can be used for testing.  
5) Note for Marine and RV installations: If starter current exceeds 500 amps, the starter  
negative must be connected to the battery side of the battery shunt so that starter current  
does not flow through it. The problem with this is that if the alternator is of the grounded  
case type its current will not be flowing through the shunt. The alternator ground must be  
isolatedfromtheengineandruntothe loadsideofthebattery shunt to beable tomeasure  
the current going into the battery from the alternator. Isolated negative output alternators  
areavailableandwestronglyrecommendthem. Withisolatednegativeoutputalternators,  
36  
 
rememberthatinstrumentation andotherloads groundeddirectlyto theengine blockwill  
not be measured unless their negatives are relocated to the load side of the Battery Shunt.  
Special high current shunts are also a solution and may be ordered from us. A separate  
engine starting battery whose negative is connected directly to the engine also solves the  
problem.  
6) Wehaveshownseveralwiresconnectedtotheloadsideofthebatteryshuntinthewiring  
diagram. If more than a few wires must be connected here, it is best to use a 2/0 jumper  
from the shunt to a good negative bus. We recommend that no more than two, or at a  
maximum three, connections per large bolt be made on the negative bus side of the shunt.  
The negative bus should be a solid copper or brass bar with many threaded screws under  
which the negatives for all of the loads may be secured. It should be fed with a conductor  
of sufficient size so that there is no appreciable voltage drop even under full load.  
WIREBYWIREINSTALLATION  
Be sure the shunt is installed before proceeding.  
The BLACK WIRE (AGND) is the Analog Ground. It is the reference for all measure-  
ments. It must be connected on the BSHG (Grounded) side of the shunt. The BSHG side  
of the shunt is the side opposite of the negative battery terminals. It must have a good  
connection to one of the two #10 screws on the top of the battery shunt.  
The RED WIRE (+12 V) is the +12 V supply. (In a 24 V system supply with +24 V.) The  
wiringdiagramshowstwooptions.ThepreferredoptionistojumpertogethertheREDand  
BLUE wires as shown. Wired this way, the meter cannot accidentally be de-powered. It  
hasthedisadvantageofalwaysconsumingalittlebitofpowerfromthe#1Battery.Themeter  
consumes about 28 mA (.028 A). If left on all the time it would use about 0.7 Ah per day.  
If the system is left on for long periods (long enough to significantly discharge the  
battery) with no charging sources then you should consider the option shown with the  
dotted line. In this case the RED wire is not jumped to the BLUE but supplied from the  
common of the battery switch. (Be sure to install the 2 A fuse as near the battery switch  
as possible.) Whichever battery is selected is the battery that supplies the power. If the

charge the battery when it is put back into service.  
The WHITE WIRE (LITE) supplies the display backlighting. It should be supplied from  
a switch that controls other instrument lighting. It may be connected to +12 V along with  
theRED wireifyouwishthelightingtobeonallthetime.Thebacklightingconsumesabout  
8 mA (.008 A). If left on all the time it would use less than 0.2 Ah per day.  
The BLUE WIRE (B1V) supplies Battery #1 voltage for sensing. It should be supplied

directly from Battery #2. Be sure to install the 2-amp fuse shown in the drawing.  
NOTE: If only one battery is to be monitored, connect the VIOLET wire to  
the BLUE wire.  
The GREEN WIRE (B1SHG) is connected to the SMALL SCREW ON THE GROUND  
SIDE, OR LOAD SIDE, of the battery #1 shunt (B1SHG). This wire must be located  
exactly as described to ensure accuracy of current measurements. The wires that run  
from the battery #1 shunt sense terminals to the GREEN AND ORANGE wires should  
be a twisted pair.  
The ORANGE WIRE (B1SHB) is connected to the SMALL SCREW ON THE  
BATTERY SIDE of the battery #1 shunt (B1SHB). This wire should be located exactly  
as described to ensure accuracy in current measurements.  
NOTE: If only one current input is used, connect the Green and Brown wires  
together and the Orange and Yellow wires together. This hookup will display the  
same current information for both the battery #1 and #2 selection.  
The BROWN WIRE (B2SHG) is connected to the SMALL SCREW ON THE  
GROUNDED, OR LOAD SIDE, of the battery #2 shunt (B2SHG). SEE ABOVE  
CAUTIONS.  
The YELLOW WIRE (B2SHB) is connected to the SMALL SCREW ON THE  
BATTERY SIDE of the Battery #2 shunt (B2SHB). The YELLOW and BROWN wires  
should be a twisted pair. SEE ABOVE CAUTIONS.  
THE INVERTER REMOTE CABLE  
The only connection between the Freedom and the Link Control Panel is a standard  
remotecable.Therearethreejacksontheback(bottom)oftheinverter.Usetheonelabeled  
REMOTE. It is best to plug the remote cable into the LINK 2000 after it is powered up.  
It is supplied with a 25' cable. You may purchase longer cords from any telephone supply  
company. You should limit its length to 50 feet. Do not run the remote cable in the same  
wireway as very noisy power conductors. This helps reduce noise interference problems.
