12 V output circuits
If the power supply unit is only powered with 12 V by the starter battery of the
towing vehicle without any connection to the 230 V mains, the following 12 V
outputs are powered:

Operation
Flat vehicle fuses
The flat vehicle fuses protect the various 12 V outputs.
The full nominal load can only be used permanently at a device temperature
of 23 °C. The outputs may therefore only be powered using maximum 10 A.
A tool for replacing the flat vehicle fuses (fuse puller) is attached next to the
vehicle flat fuses.
Change-over relay
A change-over relay is installed in the power supply unit.
The change-over relay interrupts the connection to the starter battery when
the caravan has a 230 V mains power supply. If there is no 230 V mains power
supply, the 12 V consumers are powered by the starter battery of the towing
vehicle.

▲
Blown fuses must only be replaced when the cause of the fault is
known and eliminated.
▲
Never bridge or repair fuses.
▲
Danger of burning! Blown fuses must only be changed on a zero-cur-
rent power supply unit.
▲
Only use original fuses rated as specified in the instruction manual.
▲
If the engine of the towing vehicle is switched off and if the caravan is not
connected to the 230 V mains, any 12 V consumers which are switched on
may discharge the starter battery of the towing vehicle.
