10.2 Fuse protection of the 230 V electric circuit in the vehicle
The external 230 V power supply of the vehicle is protected with 13 A circuit breakers. In addi-
tion to the circuit breakers, a ground-fault circuit breaker (special equipment) is installed in
some vehicles.
The ground-fault circuit breaker protects persons against electric shock if the insulation of elec-
trical applicances is defective.
The fuse box with circuit breakers and ground-fault circuit breaker is normally installed in the
wardrobe or a seat chest.
Checking the ground-fault circuit breaker:
 Press the "Test" button (Fig. 49/2) of the ground-fault circuit breaker with the 230 V
power supply connected.
The ground-fault circuit breaker (Fig. 49/1) triggers, the switch handle springs to the
"Off" position.
 Switch the handle of the ground-fault circuit breaker back to the "On" position after the
successful test.
Switching on the circuit breaker:
 To switch on the circuit breaker (Fig. 49/3), push the switch handle upward.
When the circuit breaker has triggered, wait for a short time before switching on again.
• If the circuit breaker remains on, only an overload occurred.
• If the circuit breaker immediately triggers again, this is due to a short-circuit or earth fault.
Consult an authorised workshop and have the fault repaired.
Important!
Check the ground-fault circuit breaker for fault-free operation monthly or, after a longer
period of standstill of the vehicle, before starting each journey.

Important!
It makes no sense to switch the breaker on several times. The circuit breaker triggers even
when you hold the switch handle.
