Model DescriptionAG-CMT-3SC AlphaGuard manages 3 batteries*AG-CMT-4SC AlphaGuard manages 4 batteries** Includes 6' battery monitoring cables.

• Battery strings contain lethal voltages. Refer to battery manufacturer's installation manual before installing or making any connections to the batteries.

• Refer to the power supply manufacturer's installation instructions before making any connections to the power supply.

WARNING! ELECTRICAL HAZARD

• The ALPHAGuard requires ventilation for proper operation and optimum life. Place the ALPHAGuard on top of the batteries, and position it so it will not fall between the batteries.

• Standby power is not available while the batteries are disconnected.

CAUTION!

The ALPHAGuard supplies electrical compensation for differences in individual batteries in the string. One ALPHAGuard is required per battery string. A wire harness connects the ALPHAGuard to each of the batteries in the string. The unit can be configuredtopassmeasurementsfromthebatterystringtoastatusmonitoringdevice(EDSMcard,DOCSIStransponder,etc.)via an interface cable.

4. Plug the battery string cable into the power supply battery input connection and the voltage sense cable into the transponder A/B connection. Turn battery breaker to the ON position.

5. After the power supply resumes charging the batteries, verify thegreenstatusindicatorLEDilluminates(>38.6for36VDCstrings;>51.4VDCfor48VDCstrings).Ifitdoesnotilluminate,verify wiring is correct and battery voltages.

When using the Voltage Sense connectionwiththeXMPowerSupplyandexternalAlphaDOCSISTransponder,clip the black wire from the cable kit at both ends. See the illustration below.
