Chapter overview
This chapter contains instructions regarding the electrical system of the ve-
hicle.
The operation of the electrical appliances of the housing body is described
in chapter 9.
8.1 General safety instructions
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 oper-
ated during the journey must have certain features: These are the CE
certification, the EMC inspection (electromagnetic compatibility) and
the "e"
‐
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.
During a storm, to protect the electrical devices disconnect the 230 V
connection and retract the antennae.
8.2 Terms
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.
The battery must remain idle for a while before measuring. After charg-
ing the last time, or after the last current has been drained by appli-
ances, wait approximately 2 hours before measuring the off-load volt-
age.
Some electrical appliances, such as the clock and the indicator lamps, re-
quire continuous electric current, for this reason they are referred to as inac-
tive appliances. This closed circuit current flows even if the device has been
switched off.
Total discharge of the battery is imminent, if a battery is completely dis-
charged by an active appliance and by closed circuit current and the off-load
voltage falls below 12 V.
Total discharge damages the battery.
Capacity refers to the amount of electricity which can be stored in a battery.
The capacity of a battery is given in ampere hours (Ah). The so-called
K20 value is normally used.
The K20 value indicates how much current a battery is able to dispense over
a time period of 20 hours without causing damage, or how much current is
required to charge a flat battery within 20 hours.
