Please note the following cable sizes:
• Cross section for connections to the heating element: min. 6 mm²
To guarantee a proper cooling performance ensure that the voltage loss is
<0.8 Vg from the power supply to the refrigerator connection terminal.
• Connections electronics and heating element: 0.75 mm

➤ Assemble your DC socket as follows (fig. j, page 10):
– 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+ from the light system 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.
➤ Connect 3 with the S+ signal (optional).
➤ Protect the supply line A with a 2 A fuse in the power distribution box of the
vehicle.
➤ Protect the supply line C with a 20 A fuse in the power distribution box of the
vehicle.
➤ Run the supply line C via an ignition-controlled relay.
This prevents the battery from completely discharging if the engine is switched
off accidentally.
WARNING! Fire hazard!
• The supply line to the heating element must be protected with a
20 A fuse.
• The supply line to the electronics must be protected with a 2 A fuse.
NOTICE!
The respective positive and negative supply lines of the DC connections
for electronics (fig. j 22, page 10) and heating element (fig. j 23,
page 10) may not be joined with one another and carried on a single
wire. This can cause electrical interference or damage to electrical
components.
