Charging using a 230 V
power supply
If the vehicle is connected to the 230 V power supply, the living area battery is
recharged by the installed charger. The charging current is adapted to suit the
charging condition of the battery. This ensures that it is not possible to overload
the battery.
To make use of the maximum output from the charger module on the transformer/
rectifier, switch off all electrical appliances during charging.
Charging using the vehicle
engine of the towing
vehicle
When the engine of the towing vehicle is running, the vehicle generator charges
the living area battery. An electrical connection between the towing vehicle and
the caravan is prerequisite for this. If the engine of the towing vehicle is switched
off, the electrical connection is automatically disconnected by a relay. This prevents
the battery of the towing vehicle from being run down by electrical appliances in
the living area. The starting capability of the towing vehicle is thus preserved.
Charging with an external
charger
When charging the living area battery with an external charger, proceed as follows:
 Disconnect the caravan electrically from the towing vehicle.
 Switch off the 12 V main switch on the panel. The indicator lamp goes out.
 Disconnect the mains plug from the transformer/rectifier.
 Switch off all gas appliances, all gas isolator taps and close the regulator tap on
the gas bottle.
 There is a danger of short circuit when disconnecting the battery poles. For this
reason, first disconnect the negative pole on the living area battery and then
the positive.
 Remove the living area battery from the vehicle.
 If the vehicle is equipped with a dryfill battery, Check whether the external
charger is approved for the dryfill battery.
 Check that the external charger is turned off.
 Connect the external charger to the living area battery. Pay attention to the
polarity: First connect the positive terminal "+" to the positive pole of the bat-
tery, then connect the negative terminal "–" to the negative pole of the battery.
 Switch on the external charger.
 See the instructions for use of the connected charger for information con-
cerning charge period required for the battery.
 See the specifications on the battery for information concerning its strength.
 Disconnect the external charger in reverse order.
9.4 Power pack
The power pack is installed in the wardrobe.
Z When the ignition is switched off and there is no connection to the 230 V power
supply, the battery of the towing vehicle is discharged by consumers such as
the refrigerator or the living are lamps (exception: Autark Package). The starting
capability of the towing vehicle can be impaired.
Z The towing vehicle battery is not charged by the power pack.
