7. Installation of electrical devices
Operation via auxiliary battery*
(self-sufficient package)
• Only accumulator batteries with bound electrolytes
(gel or AGM batteries) may be installed in those po-
sitions specified by the manufacturer.
• The installed battery may not be opened.
• When changing auxiliary batteries, use only batteries
of the same make and capacity.
(Setting the battery type on the control panel:
see p. 60)
• Before disconnecting or connecting the auxiliary
battery, disconnect the electric connection to the
base vehicle and switch off the 230 V supply, the 12
V supply as well as all electrical devices.
• Before replacing fuses you must first de-energise
the charge controller.
• Before replacing a blown fuse you must first fix
whatever caused the fuse to blow.
• Fuses may only be replaced by fuses with the same
fuse protection value.
• Airing the charge controller insufficiently will cause a
reduction of the charge current.
• The surface of the charge controller casing may be-
come hot when the device is in operation.
Operating and loading the auxiliary battery
If the caravan is not connected to the 230 V mains supply, the auxi-
liary battery will supply the electrical system with 12 V DC voltage.
Since the battery only has a limited capacity, the electrical devices
should not be operated for a longer period of time without charging
the battery or connecting the caravan to the 230 V mains connection.
The charge controller is used to charge the battery. There are three
possible sources of input: (230V mains connection, generator in the
base vehicle or solar panel*, if applicable) whereby the source of
input with the highest input voltage supplies the charge current for
the connected battery.
An Intelligent Battery Sensor (IBS) has been connected to the battery
terminal. It monitors the actual current and the actual voltage in a
highly precise manner.
It is possible to precisely predetermine the operating time of the
battery based on the actual consumption. The IBS ensures that the
battery will be changed in good time and assists in providing active
energy management 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 discharge
are all shown on the TFT display of the control panel. Charging is
carried out gently in accordance with the steady-state principle by
an "intelligent" charger.
