8.7 AC converter (MSI 1812T)
 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.

When connecting appliances, always observe the permissible values for
output power and peak output power:
̶ Output power (for 10 min at 25 °C): 1800 W
̶ Peak output power: 3200 W
Appliances with higher power demands must not be connected.

Do not cover the ventilation slots. Danger of overheating!

Do not place additional objects in the storage space of the AC converter.
Danger of overheating!

Check the fault current protection switch for each connection to the
230 V power supply, at least once every 6 months.

If the vehicle is not connected to the 230 V power supply and no electric-
ity is required, switch off the AC converter. Even in idle state, the AC
converter still uses power from the living area battery.

The AC converter is equipped with a 230 V priority circuit. If an external
230 V voltage is connected, it will be used primarily. Only if no external
230 V voltage is connected, the living area battery will be used for volt-
age supply.

If not external 230 V power supply is connected, the AC converter draws
energy from the living area battery. The living area battery has a limited
power supply only. For this reason, the electrical appliances should not
be operated from the electrical sockets for long periods without using the
230 V connection.

To protect the living area battery against total discharge, the AC con-
verter automatically switches itself off if there is undervoltage. The AC
converter automatically switches itself on again when the voltage is back
up to the standard value.

In the event of overload or insufficient cooling, the AC converter
switches itself off automatically. The AC converter automatically
switches itself back on when there is no longer an overload and the tem-
perature of the device is down to a safe level.

If the appliance fuse has triggered, it must be pushed in again manually.

manual.
