
The 230 V connection in the vehicle is equipped with a fault current pro-
tection switch (FI-switch).

For the connection points on camp sites (camping distributors) fault cur-
rent protection switches (FI-switches, 30 mA) are obligatory.
The vehicle can be connected to an external 230 V power supply. As a prin-
ciple, only use the 230 V connection on the vehicle (CEE socket outlet) for
connecting.
