8.9.3 230 V fuse
For vehicles with and AC converter as special equipment, observe the fol-
lowing:
If, when the AC converter is switched on, the 230 V connection is dis-
connected or the 230 V main fuse is switched off, this will not activate
the sockets since these are supplied by the AC converter.
The safety cut-out in the additional fuse box for the AC converter se-
cures and breaks the circuit only for the sockets in the vehicle.
Only by switching off both fuse boxes and the AC converter is the
mains power supply fully activated.
Check the fault current protection switch for each connection to the
230 V power supply, at least once every 6 months.
Fig. 146 Safety cutout and FI-switch
(230 V fuse box)
A fault current protection switch (FI-switch) (Fig. 146,3) in the fuse box pro-
tects the complete vehicle from fault current (30 mA).
The downstream safety cut-out (10 A) (Fig. 146,1) secures the 230 V sock-
ets, the transformer/rectifier, the auxiliary charging unit and the refrigerator.
For vehicles with special equipment, e.g. roof air conditioning unit, the de-
vice is protected by an additional safety cut-out (16 A) (Fig. 146,2).
When the vehicle is connected to the 230 V power supply, press the test
button (Fig. 146,4). The fault current protection switch (FI-switch) must
be activated.
The fuse box is installed close to the 230 V connection.
