7. Installation of electrical
devices
Operation via battery*
(self-sufficient package)
•
Only accumulator batteries with bound electrolytes (gel
or AGM batteries) may be installed in those positions
specified by the manufacturer.
• The installed battery may not be opened.
• When changing batteries, use only batteries of the same
make and capacity.
• Before disconnecting or connecting the battery, dis
-
connect the electric connection to the tow vehicle and
switch off the 230V supply, the 12V supply as well as all
electrical devices.
• Before replacing fuses you must first turn off the battery
charger.
• Before replacing a blown fuse you must first fix what-
ever caused the fuse to blow.
• Fuses should only be replaced by fuses with the same
fuse protection value.
Using and charging the battery
If the caravan is not connected to the 230V mains supply, the battery
will supply the electrical system with 12V DC voltage (the 230V sockets
are not active in this operating mode).
Since the battery only has a limited capacity, the electrical devices
should not be operated for a long periods of time without charging
the battery or connecting the caravan to the 230V mains connection.
Some electrical devices continuously use standby current from the
battery. This flattens the battery. The battery is charged via the battery
charger from two possible input sources:
-
230V mains connection
- from the car’s alternator when connected to the caravan by means
of the 13-pin plug and only if the ignition has been switched on.
Battery
Battery Sensor
An Intelligent Battery Sensor (IBS) has been connected to the battery
terminal. It measures and monitors the actual current, actual voltage
and temperature of the batteries in a highly precise manner. Normally,
the battery sensor is calibrated automatically.
Intelligent Battery Sensor (IBS)
It is possible to determine the operating time of the battery based
on the current consumption. The IBS ensures that the battery will be
charged in good time and assists in providing active energy manage
-
ment so that the performance requirements of the different electrical
devices can be coordinated with the charging of the battery.
The charge state of the battery, age or remaining time until it is too low
to operate are all shown on the display of the control panel. Charging
is carried out gently in accordance with the steady-state principle by
an "intelligent" charger.
If there is a loss of power in the battery sensor (voltage
absent), you must recalibrate.
The battery sensor is protected with 10A.
