Connecting the refrigerator
➤ Secure the power supply line to the heating element (connections 3 and
4) with a 16 A fuse and the supply for lighting/electronics (connections 5
and 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 vehicle battery
from completely discharging if the engine is switched off accidentally
(fig. g, page 14).
➤ RM5385 only: Connect a DC permanent supply to the connection for
lighting/electronics (connections 5 and 6).
D+ (RM5385 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. f D, page 13) with the
respective terminal of the vehicle.
S+ (RM5385 only)
In automatic mode, the refrigerator is first powered with DC power from
the vehicle'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. f E, page 13) to the
respective terminal of the solar charge controller.
Suitable solar charge controllers are available from specialist dealers.
