Battery selector switch

If the battery selector switch is set incorrectly, there is the danger of the
formation of detonating (oxy-hydrogen gas). Danger of explosion!
Incorrect setting of the battery selector switch damages the living area bat-
tery.
The factory settings of the battery selector switch must not be changed.
The battery selector switch is used to set the charger module in the trans-
former/rectifier to the type of living area battery installed in the vehicle ("lead
acid" or "dryfill" battery).

Battery monitor

You must fully recharge a discharged living area battery as soon as pos-
sible.
The battery monitor in the transformer/rectifier monitors the voltage in the
living area battery.
If the battery voltage falls below 10.5 V, the battery monitor in the transformer/
rectifier switches off all of the 12 V appliances, excluding the safety/drainage
valve.
A refrigerator with automatic power selection system switches to gas opera-
tion.
Switch off all electrical appliances that are not absolutely essential at the
corresponding switch.
If necessary, use the 12 V main switch to switch the 12 V power supply
back on for a short while. This is only possible, however, when the battery
voltage is above 11 V. If the voltage is below this level, the 12 V power
supply cannot be switched on again until the living area battery has been
recharged.

Charging the battery

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.
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.
