NOTICE!
The respective positive and negative supply lines of the DC connections
for electronics (fig. l 16, page 12) and heating element (fig. l 17,
page 12) may not be joined with one another and carried on a single
wire. This can cause electrical interference or damage to electrical com-
ponents.
Please note the following cable sizes (fig. m, page 14):
• Connections heating element:
– <6 m (in the interior): ≥6 mm
– >6 m (in the interior): ≥10 mm
– Cable fed via drawbar (caravans only): ≥2.5 mm
• Connections electronics: ≥0.75 mm
• Connections D+ and S+: ≥0.75 mm
1. Assemble your DC socket as follows (fig. l, page 12):
– Connect A and C to the positive pole of the battery.
– Connect D and F to Connect D and F to ground.
– Connect B to the D+ signal.
The electronics of the refrigerator uses the signal D+ of the alternator to
detect the running engine. In automatic mode, the refrigerator selects the
most favorable mode available. The refrigerator is only operated with direct
current when the vehicle engine is running.
– Connect E to the CI-BUS.
2. Connect 10 with the S+ signal (optional).
3. Protect the supply line A with a 2 A fuse in the power distribution box of the
vehicle.
4. Protect the supply line C with a 15 A fuse in the power distribution box of the
vehicle.
5. Run the supply line C via an ignition-controlled relay.
This prevents the battery from completely discharging if the engine is switched
off accidentally.
