Appliances such as the refrigerator, charger, solar charge regulator,
panel, or similar, take power from the battery, even when the 12 V main
switch is turned off. Therefore disconnect the living area battery from the
12 V power supply, if the vehicle will not be used for a long period of
time.
8.3.2 Charging batteries via a 230 V power supply
If the vehicle is connected to the 230 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 only charged with a float
charge. 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.
8.3.3 Charging batteries via the vehicle engine
When the vehicle engine is running, the vehicle alternator recharges the liv-
ing 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.
8.3.4 Charging the starter battery
The acid in the battery is poisonous and corrosive. Any contact with
the skin or the eyes is to be avoided. In the event of contact, rinse im-
mediately with plenty of water (skin, eyes, clothes, objects) and seek
medical attention if necessary.
In the case of charging with an external charger there is danger of ex-
plosion. Sparks can be caused by attaching the battery terminals.
Only charge the battery in a well ventilated area and away from naked
flames or possible sources of sparks. Batteries can develop and re-
lease gases when they are charged.
Always remove the starter battery from the vehicle when charging it
using an external charger.
Do not connect the battery cables to the wrong poles
(red cable -> positive pole, black cable-> negative pole).
Do not actuate the ignition if the terminals of the battery are discon-
nected. Danger of short circuit!
Before disconnecting or connecting the terminals of the battery, switch
off the vehicle engine as well as the 230 V and 12 V power supplies and
all appliances. Danger of short circuit!
Before charging the battery, check whether the external charger is ap-
proved for the battery type.
