Electrical system 8
When the vehicle is not connected to the 240 V power supply or the 240 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 240 V power supply.
Discharging The living area battery is discharged by the closed circuit current which some
electrical appliances continuously require.
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.
In order to prevent fast discharge of the living area battery, the refrigerator is
operated on 12 V power supply only when the engine is running and when
there is an electrical connection between the towing vehicle and caravan.
Charging Only use the power supply unit to charge the living area battery. Therefore,
connect the vehicle to a 240 V power supply system as often as possible.
The living area battery is recharged by the alternator of the towing vehicle if
the caravan is connected electrically to the towing vehicle and the towing
vehicle's engine is running.
Z
Before disconnecting or connecting the terminals of the living area battery,
switch off the engine of the towing vehicle as well as the 240 V and 12 V
power supplies and all appliances. Danger of short circuit!
Z
If the living area battery is disconnected and the caravan and towing
vehicle are connected electrically, do not apply the ignition. There is a
danger of short circuit from exposed cable ends.
Z
The battery is maintenance-free. Maintenance-free means:
It is not necessary to check the acid level.
It is not necessary to lubricate the battery poles.
It is not necessary to refill the distilled water.
Even a maintenance-free battery must be charged regularly.
Z
Total discharge damages the battery.
Z
Recharge battery in good time.
Z
Charge the battery for at least 48 hours after a total discharge.
Z
At temperatures below 0 °C, a dryfill battery consumes less power. At
approx. -15 °C, there will be no more power. The living area battery can no
longer be charged.
Z
Further information can be obtained in the separate documentation for the
living area battery.
