7.1 Shore Power
The shore power option allows HVAC functions to operate off an external 120 VAC power source instead of
running the diesel engine. When operating in shore power mode, the 120 VAC power source is
automatically switched between the APU and shore power connection. The default power source is the
APU. The APU engine does not run in shore power mode.
The shore power option consists of the following:
• Shore Power Manager (SPM): Controls incoming power source from the APU or shore power.
• Battery Charger: Maintains DC power drawn from the truck batteries.
• Shore Power Receptacle (120 VAC/15A): Allows connection to shore power.
