Installation Manual 6
1. Select Wire Size
-The refrigerator power supply can be run with either single cables or two sets of cables. Reference the table to determine the
maxium wire length for a given wire size and wiring method.
Cable Size Acceptance
2. To protect the DC power supply wiring, install a fuse or circuit breaker in the positive (+) DC power supply wire as close to the battery
or power source as possible. The fuse should be sized according to the ANSI/RVIA Standard for Low Voltage Systems in Conversion
and Recreational Vehicles.
- There is a 15 amp automotive fuse in the DC circuit at the refrigerator power supply leads to protect the controls of the refrigerator.
This amp should only be replaced with a 15 amp automotive fuse.
3. Connect the DC power supply wires.
If the DC power supply leads are attached incorrectly, the refrigerator will not operate.
-Connect the first positive (+) DC power supply lead to the positive (+) terminal identified as circuit 1.
-Connect the first negative (-) DC power supply lead to the negative (-) terminal identified as circuit 1.
If 2 sets of power cables are used:
-Connect the second positive (+) DC power supply lead to the positive (+) terminal identified as circuit 2.
-Connect the second negative (-) DC power supply lead to the negative (-) terminal identified as circuit 2.
- Make sure that:
- 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 including the fuses are routed directly from the power source to the refrigerator.
- The wire connections must be clean, tight and free of corrosion. If any of these items are not correct, a voltage drop to the
refrigerator will occur.
The voltage drop will decrease the cooling performance of the refrigerator. 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.
Allow the refrigerator to stand upright for 30 minutes before being powered on.
