Installation Manual 14
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. The voltage drop decreases the DC input voltage to the main control
board which could then aect cooling performance.
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 re can result.
- On 2-way models, use a minimum of 18 AWG wire and a maximum 6 Amp fuse.
- On 3-way models, measure the distance from the vehicle battery to the refrigerator.
- If the distance is 0 - 20 feet, use a minimum of 10 AWG wire and a maximum 30 Amp fuse.
- If the distance is over 20 feet, use a minimum of 8 AWG wire and a maximum 40 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 Art 02763):
- Attach a 1/4 inch Quick Connect terminal to each DC power supply wire.
- Make sure each DC power supply wire is on the correct polarity terminal.
On 2-way models (See Art 02763)
- Push the positive DC power wire onto the power board terminal that is marked 12VDC [288].
- Push the DC ground wire onto the power board terminal that is marked GND [287].
On 3-way modelsOn 3-way models (See Art 02794)
- Push the positive DC power wire onto the power board terminal that is marked 12VDC [288].
- Push the DC ground wire onto the power board terminal that is marked GND [287].
Do not use the chassis of the refrigerator or the vehicle frame as one of the conductors. Attach the DC power supply
wires only to the battery and the main control board input terminals [287 & 288].
