Connecting the refrigerator
DC power:
Please note the following cable sizes:
– < 6 m (interior): 6 mm
– > 6 m (interior): 10 mm
– Connections D+ and S+: 1 mm
– Cable fed via drawbar (caravans only): 2.5 mm
➤ Secure the power supply line to the heating element (connection 4) with a
20 A fuse and the supply for lighting/electronics (connection 6) with a 2 A fuse.
➤ Connect the heating element (connections 3 and 4) with the shortest possible
cable.
➤ Run the cable to the heating element (connections 3 and 4) via a relay controlled
by an ignition socket to prevent the battery from completely discharging if the
engine is switched off accidentally (fig. w, page 13).
➤ RML9331/9335/9431/9435 only: Connect a 12 V continuous supply to the
connection for lighting/electronics (terminals 5 and 6).
D+ (RML9335/9435 only)
In automatic mode, the refrigerator selects the most favourable mode available. The
refrigerator is only operated with direct current when the vehicle engine is running.
The electronics of the refrigerator uses the signal D+ from the light system to detect
the running engine.
➤ Connect the D+ connection to the controls (fig. v D, page 12) with the
respective terminal of the vehicle.
S+ (RML9335/9435 only)
In automatic mode, the refrigerator is first powered with DC power from the vehi-
cle's own solar system. The refrigerator electronics uses the S+ signal of the solar
charge controller to detect a solar system. The solar charge controller must have an
AES output.
➤ Connect the S+ connection on the controller (fig. w E, page 13) to the
respective terminal of the solar charge controller.
Suitable solar charge controllers are available from specialist dealers.
The manufacturer recommends, for example:
• Büttner MT 300-S
