The instructions address the following topics:
safety
explanations of terms relating to the battery
12 V power supply
living area battery
loading the batteries
transformer/rectifier
panel

The operation of the electrical appliances of the housing body is described in
chapter 10.
9.1 General safety instructions
The vehicle is a safe place during a storm (Faraday cage). However, to protect
the electrical devices, disconnect the 240 V connection and retract the
antennae as a precaution.
9.2 Terms
Off-load voltage The off-load voltage is the voltage of the battery in idle condition, i. e. no cur-
rent is consumed and the battery is not being charged.
Closed circuit current Some electrical appliances, such as the clock and the indicator lamps, require
continuous electric current, for this reason they are referred to as inactive
appliances. This closed circuit current flows even if the 12 V power supply has
been switched off.
Total discharge Total discharge of the battery is imminent, if a battery is completely discharged
by an active appliance and by closed circuit current.
Capacity Capacity refers to the amount of electricity which can be stored in a battery.
Only allow qualified personnel to work on the electrical system.
All electronic devices (e.g. mobile telephones, radios, televisions or DVD
players) which have been retrofitted to the vehicle and are operated
during the journey must have certain features: These are the CE certifi-
cation, the EMC inspection (electromagnetic compatibility) and the "E1"
inspection.
Only in this way can the functional reliability of the vehicle be ensured.
Otherwise the airbag may be triggered or interference to the on-board
electronics may result.
Total discharge damages the battery.
