➤ Connect a 12 V continuous supply to the connection for lighting/electronics.
D+
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. k 8, page 8) with the
respective terminal of the vehicle.
S+
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. k 10, page 8) ) to the
respective terminal of the solar charge controller.
➤ Connect the heating element (fig. k 18, page 8) to the battery.
