The starter battery can only be fully charged with an external charger. If a
240 V power supply is used, the transformer/rectifier charges the starter bat-
tery with a float charge only. Even in mobile operation, the vehicle engine alter-
nator is not capable of completely charging the starter battery.
Charging using a 240 V power supply
If the vehicle is connected to the 240 V power supply, the living area battery
and the starter battery are automatically charged by the charger module on the
transformer/rectifier. The starter battery is charged with a float charge of 2 A.
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 trans-
former/rectifier, switch off all electrical appliances during charging.
Charging using the vehicle engine
When the vehicle engine is running, the vehicle alternator recharges the living
area battery and the starter battery. When the vehicle engine is switched off,
the batteries are automatically disconnected from one another by a relay in the
transformer/rectifier. This prevents the starter battery from being run down by
electrical appliances in the living area. The starting capability of the vehicle is
thus preserved. The charging condition of the living area battery or the starter
battery can be read on the panel.
Charging with an external charger
When charging the living area battery and the starter battery with an external
charger, proceed as follows:
Turn off the vehicle engine.
Switch off 12 V main switch on the panel. The indicator lamp will go off.
On the transformer/rectifier, move the battery cut-off switch to the position
"Batterie Aus" (battery OFF).
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 terminal on the living area battery
or the starter battery and then the positive.
Remove the living area battery or the starter battery from the vehicle.
Check that the external charger is turned off.
Connect the external charger to the living area battery or the starter battery.
Pay attention to the polarity: First connect the positive terminal "+" to the
positive pole of the battery, 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.
