9.5.1 Battery cut-off switch
The battery cut-off switch disconnects all the living area 12 V appliances, even
the safety/drainage valve. This prevents the living area battery from slowly dis-
charging if the vehicle is not used for a longer period of time (e.g. temporary
lay-up).
The batteries can still be charged by the transformer/rectifier when the battery
cut-off switch is turned off.
Switching on/off:
Press the battery cut-off switch up: Battery ON ("Batterie EIN").
Press the battery cut-off switch down: Battery OFF ("Batterie AUS").
9.5.2 Battery selector switch
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).
9.5.3 Battery monitor
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.
When the battery cut-off switch is OFF, the safety/drainage valve opens.
The water flows out of the boiler. When the battery cut-off switch is ON
again, close the safety/drainage valve of the boiler by hand.
Also switch off a refrigerator with automatic power selection system. The
refrigerator will otherwise switch to gas operation.
After switching the battery cut-off switch back on again: Put the basic light
(lighting in the entrance area), entrance step, heater and spare 4 back into
service (depending on the model). To do so, switch on the 12 V main switch
briefly. This also applies if the living area battery was disconnected and
then reconnected.
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.
You must fully recharge a discharged living area battery as soon as pos-
sible.
