For example, if a battery can dispense 4 amps for 20 hours, then it has a
capacity of 4 A x 20 h = 80 Ah.
If more current flows, the discharging time of the battery will decrease pro-
portionately.
External influences, such as temperature and age may alter the storage ca-
pacity of the battery. Capacity details refer to new batteries operating at
room temperature.
Depending on battery technology, capacity details have a conversion
factor of 1.3 to 1.7, which lowers the real capacity by this value.
8.3 12 V power supply
To disconnect
all
electrical 12 V appliances from the power supply, dis-
connect the living area battery from the 12 V power supply. In order to
do this, actuate the switch on the transformer/rectifier.
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 refrigerator and the heater(cir-
culation fan) should not be operated for a long time without using the 230 V
power supply.
During heater operation, the circulation fan is switched on and off by a ther-
mostat control. As a result the living area battery is loaded if no 230 V power
supply is connected.
In the case of longer lay-ups of the vehicle, all 12 V appliances must be
switched off to avoid discharging the living area battery.
Switch off battery cut-off switch on the transformer/rectifier. Thus, the liv-
ing area battery is fully disconnected from all electrical appliances.
If you leave the vehicle briefly and the refrigerator and/or the heater shall
continue working, it suffices to switch off all 12 V appliances not required.
Yet nevertheless, observe the charging condition of the living area battery.
Switch off 12 V main switch on the panel. Heater, refrigerator, entrance
step / basic light are still supplied with power.
8.3.1 Living area battery
Disconnecting and connecting the terminals, as well as changing the liv-
ing area battery shall only be carried out by qualified personnel. In the
event of an incorrect connection, there is the risk of short circuit and fire
due to rubbing cables. To reach the living area battery, the seat as well
as its turning device must be removed. These components are security
related and shall be fitted professionally with screw lock and complying
with defined tightening torques.
Prior to commencing a journey ensure the living area battery is fully
charged. For this reason charge the living area battery for at least
20 hours before commencing the journey.
During the trip, use every opportunity to charge the living area battery.
After the trip, charge the living area battery fully.
