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.
