A certified electrician should verify that the proper standby power
requirements are being supplied before connecting to a new power source.
These units may be operated in electric standby mode by connecting the
proper voltage power cable to the unit’s power receptacle mounted on the
vehicle. Standby operation is used while the vehicle is stationary with the
engine shut off.

Standby Power Receptacle
Electrical System
The unit’s controls and refrigeration components operate on 12 Vdc.
SmartPower units have a standby motor that operates on 115 or 230 Vac
when connected to a remote power source. A transformer in the condenser
unit converts the 115 or 230 Vac to 12 Vdc to operate the unit’s controls and
refrigeration components.
Fuses
The electrical components are protected by various fuses.
