Connect the Electrical Components

AC Operation
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.
The rear of the refrigerator cooling system has hot surfaces and sharp surfaces that can damage electrical
!
WARNING
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:

Connect the AC power cord(s) only to a grounded three-prong receptacle. Do not remove the round
!
WARNING
ground prong from any of the AC power cords. Do not use a two prong adapter or an extension cord with
any of the AC power cords. 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:

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.
1. Determine the min. wire size and the max. fuse size to use:
! If you use an incorrect wire size and/or fuse size, electrical fire can result.
WARNING
- 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.
2. Install a fuse in DC power supply wires between the battery and the refrigerator:
- Put fuse as close to the battery as possible.
3. Connect the DC power supply wires (See Art00966):
- Attach a 1/4 inch Quick Connect terminal to each DC power supply wire.
Do not use the chassis of the refrigerator or the vehicle frame as one of the
NOTICE
conductors. Attach the DC power supply wires only to the battery and the
power board [49] of the refrigerator.
- Push the positive DC power wire [50] onto the power board terminal that is marked
12VDC.
- Push the DC ground wire [51] onto the power board terminal that is marked GND.
- Make sure each DC power supply wire is on the correct polarity terminal.
