Connect the 12/24 volts DC supply:

To reduce the risk of electrical interference from other DC appliances and induction from voltage spikes:
- The refrigerator must have an independent 12/24 volt DC supply.
- Route the DC power supply wires including the fuse directly from the battery to the refrigerator.
- Twist the DC power supply wires from the battery to the refrigerator.
The electronic unit is protected against reverse battery connection. For protection during installation, a
NOTICE
fuse must be mounted in the + cable as close to the battery as possible. A 15A fuse for the 12V and a 15A
fuse for the 24V circuits are recommended. If the main switch is used, it should be rated to a current of min.
20A. The wire dimensions in Fig. 4 must be observed. Avoid extra junctions in the power supply system to
prevent voltage drop from affecting the battery protection setting.
