Caution: The DCDC will turn on when the ignition is on. This means that even if your engine is
not on, the starter battery will immediately be used to power the DCDC and start charging the
house battery. It is recommended to have the vehicle completely on.
IMPORTANT: A D+ ignition cable is required to turn the unit on. Although the D+ terminal is
in the output side, this will be connected to the INPUT Alternator/Starter Battery.

Operation
When the input and output batteries as well as the signal wire is connected, the DCDC will power on
