Fig. 135 AC converter (exemplary il-
lustration)
The AC converter has the following functions:
If no external 230 V power supply is connected, the AC converter generates
a 230 V voltage for all sockets in the vehicle out of the 12 V DC voltage of
the living area battery.
If an external 230 V power supply is connected, this will be used to supply
the sockets. In this case, the AC converter will not draw power from the liv-
ing area battery.
1 Fuse box
2 Safety cut-out for sockets
3 Fault current protection switch for
sockets

The sockets are protected by a safety cut-out (Fig. 136,2) and a fault current
protection switch (Fig. 136,3) in the additional fuse box (Fig. 136,1).
The AC converter and the additional fuse box are installed in the double
floor and accessible via a floor trap.
The operating controls are located on the front of the AC converter.
