Electrical system
8
When the vehicle is not connected to the 230 V power supply or the 230 V
power supply is switched off, the living area battery supplies the living area
with 12 V DC. The living area battery has a limited power supply only. For this
reason, electrical appliances such as the radio and the lights should not be
operated for a long time without using the 230 V power supply.
Position
The living area battery is installed behind the bench, underneath the cabinet
underneath the storage flap.
Discharging
The living area battery is discharged by the closed circuit current which some
electrical appliances continuously require.
Even a fully charged living area battery can, after an extended period, be fully
discharged via a closed-circuit current (inactive appliances).
Low temperatures outside reduce the capacity available.
The self-discharge rate of the battery is also dependant on temperature. At 20
to 25 °C the self-discharge rate is approx. 3 % of the capacity per month. The
self-discharge rate will increase with rising temperatures: At 35 °C the self-dis-
charge rate is approx. 20 % of the capacity per month.
An older battery no longer has the complete capacity available.
The higher the number of active electrical appliances, the faster the energy of
the living area battery is consumed.
Charging
Only use the transformer/rectifier to charge the living area battery. Therefore,
connect the vehicle to a 230 V power supply system as often as possible.
Z
Charge the battery for at least 48 hours after a total discharge.

Energy balance of the living area battery
The living area battery has a limited power supply only. For this reason, the
electrical appliances should not be operated without a 230 V power supply for
a longer period of time.
Z
If the living area battery is replaced and the charging unit does not provide
at least 10 % of the rating of a new battery, install an auxiliary charging unit.
Example: With a battery capacity of 80 Ah, the charging unit must supply
at least 8 A charging current.
Z
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!
Z
If the starter battery or living area battery are disconnected, do not apply
the ignition. There is a danger of short circuit from exposed cable ends.
Z
Only connect devices with a maximum of 10 A to the sockets of the 12 V
power supply.
Z
If there are two living area batteries: When changing, ensure that the bat-
teries are properly installed. Install the batteries so that the positive ter-
minal on one battery is lying next to the negative terminal of the other
battery.
Z
If there are two living area batteries: When changing, ensure that the bat-
teries are properly connected.
Z
Total discharge damages the battery.
Z
Recharge battery in good time.
