
When the vehicle is connected to the 230 V power supply, press the test
button on the fault current protection switch (Fig. 136,3). The fault cur-
rent protection switch (FI-switch) must be activated.
8.8 230 V power supply
 Only allow qualified personnel to work on the electrical system.
 Have the vehicle's electrical system checked by a qualified electrician
at least once every 3 years. If the vehicle is used frequently, an an-
nual check is recommended.
The 230 V power supply provides electricity for the following devices (if pre-
sent):

sockets with earth contact for appliances with maximum 10 A

refrigerator

transformer/rectifier

an auxiliary charging unit

air conditioning unit
The electrical appliances connected to the 12 V power supply of the living
area are supplied with voltage by the living area battery.
Connect the vehicle to an external 230 V power supply system as often as
possible. The charger module in the transformer/rectifier automatically
charges the living area battery. In addition to this, the starter battery is
charged with a float charge of 2 A.
Depending on the equipment, optional devices are fuse-protected by their
own two-pole automatic circuit breaker.
8.8.1 230 V connection (CEE socket outlet)

Overvoltage can damage connected devices. Overvoltage can be
caused by lightning, irregular voltage sources (e.g. petrol-operated gen-
erators) or power connections on ferries for example.

The connecting cable, the plug connectors at the point of supply and the
plug connector to the vehicle must comply with IEC 60309. The stand-
ard designation for the plug connectors is "CEE blue".

Use H07RN-F rubber sheathed cable with a minimum cable cross-sec-
tion of 2.5 mm² and a maximum length of 25 m.

Earth contact connectors (safety) are not permitted. The interconnection
of CEE/safety adapters is also prohibited.
8.8.2 Connecting the 230 V power supply
 The external 230 V power supply must be protected by fuse with a
fault current protection switch (FI-switches, 30 mA).
 To prevent overheating, the cable must be fully uncoiled from the ca-
ble reel.
 In case of doubt or if the 230 V supply is not available or is faulty, con-
tact the operator of the power supply device.
