Connect the Electrical Components

This refrigerator operates on these electrical sources. Operation out of these limits may damage the refrigerator's electrical circuit parts
and will void the warranty.
AC Operation 120 volts AC voltage
12 volts DC control voltage
!
WARNING:
The rear of the refrigerator cooling system has hot surfaces and sharp surfaces that can damage electrical wiring.
Make sure that there is a good clearance between all electrical wiring and the cooling system of the refrigerator. Position any
electrical wiring within the refrigerator enclosure opposite the burner side of the refrigerator. Do not put any electrical wiring
through the roof exhaust vent. Failure to correctly position electrical wiring can result in electrical shock or fire.

Connect the 120 volts AC supply:

!
WARNING:
Connect the AC power cord(s) only to a grounded three-prong receptacle. Do not remove the round ground prong
from the AC power cord of the refrigerator or the ice maker (optional). Do not use a two prong adapter or an extension cord with
either AC power cord. Operation of the refrigerator without correct ground can cause dangerous electrical shock or death if you
are touching the metal parts of the refrigerator.
Put the AC power cord(s) into a grounded three-prong receptacle:
- Make sure the receptacle is positioned within easy reach of the lower intake vent.
- Make sure the power cord(s) does not touch the burner cover, the flue pipe, or any hot component that could damage the insulation
of the power cord.

Connect the 12 volts DC supply:

The refrigerator controls operate on 12 VDC power. As the distance from the vehicle battery to the refrigerator increases, the correct
AWG wire size and fuse size also increases. If the wire size is too small for the distance, a voltage drop occurs.
Use a minimum of 18 AWG wire and a maximum 6 Amp fuse. If the wire size is larger than the min. size, use the correct fuse per RVIA
A119.2 standard or local codes.
1. Install a fuse in DC power supply wires between the battery and the refrigerator:
- Put fuse as close to the battery as possible.
2. Connect the DC power supply wires (See Art01748):
- Attach a 1/4 inch Quick Connect terminal to each DC power
supply wire.
NOTE: Do not use the chassis of the refrigerator or the vehicle
frame as one of the conductors.
- Connect the positive DC power wire [50] to the teminal on the
power board [49] that is marked 12VDC.
- Push the DC ground wire [51] onto the terminal of the power
board [49] that is marked GND.
- Make sure each DC power supply wire is on the correct polarity
terminal.
