ATTENTION
Hazard of damage to the electrical and electronic systems of the machine.
– The main battery switch may not be switched off while the engine is running and
the ignition is switched on.
6.23.1 Voltage monitoring
The battery voltage is monitored by the system. If the voltage is too high or too low,
then the warning icon is displayed on the R-Touch. The battery voltage may not
exceed 32 V and may not fall below 24 V. As experience has shown, the machine can-
not be started with a battery voltage of less than 24 Volts.
When a generator fails, the following icon appears on the R-Touch.
6.23.2 Disconnecting timer from vehicle power supply
The electrical system (except for the timer for park heating and the ladder lights) can
be completely disconnected from the batteries with the main battery switch. The main
battery switch is in the roof console. If the park heating timer (very low continuous
power consumption!) is also disconnected from the power supply, fuse F03 (1) in the
terminal box of the central electrical system must be removed. (see page 382)
