As the distance from the vehicle battery to the refrigerator increases, the correct AWG wire size also
increases. If the wire size is too small for the distance, a voltage drop will occur. The voltage drop will
decrease the cooling performance of the refrigerator.
WARNING
!
ATTENTION
1. Find the minimum wire size to use by measuring the distance from the vehicle battery to the
refrigerator:
- If the distance is 0 - 12 feet, use #12 AWG min. wire size
- If the distance is 12-20 feet, use #10AWG min. wire size
- If the distance is over 20 feet, use #8AWG min. wire size
2. To protect the DC power supply wiring, install a 15 amp fuse or circuit breaker in the positive(+) DC
power supply wire as close to the battery as possible. There is a 15 amp fuse in the DC circuit at the
refrigerator power supply leads
NOTICE
3. Connect the DC power supply wires .
- Connect the positive (+) DC power supply lead to the red wire of the refrigerator
- Connect the negative (-) DC power supply lead to the black wire of the refrigerator
Ensure the following:
- Each DC power supply lead is attached to the correct polarity wire of the refrigerator power supply
- The chassis or the vehicle frame is not used as one of the conductors
- The DC power supply wires and fuses are routed directly from the battery to the refrigerator
- The wire connections must be clean, tight, and free of corrosion
CAUTION

Battery
Art02376
Use only the recommended wire size.
If the DC power supply leads are attached incorrectly, the refrigerator will
not operate.
Disconnect the positive(+) DC power supply wire from the battery before
you do a "fast charge" of the battery. Failure to disconnect the positive
(+) power supply wire from the battery during a "fast charge" can cause
damage to the refrigerator or other DC appliances.
