4.3 Controller Power

The DC2 controller is powered by the generator set engine starting battery.

Note: To disconnect controller power, disconnect the utility power to the generator set and disconnect the battery (negative lead first).

4.4 Battery Charging

The controller includes a built-in battery charger to maintain the engine starting battery. The DC2 controller monitors the battery voltage and provides a constant 14 ±2% VDC voltage and maximum 2.5 amps to charge the battery.

The installer must connect 120 VAC/60Hz utility power provided from the building on a breaker-protected circuit for the built-in battery charger. See the Installation Manual for instructions to connect power.
