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.
• Only accumulator batteries with bound electrolytes
(gelorAGMbatteries)maybeinstalledinthosepo-
sitionsspeciedbythemanufacturer.
•Theinstalledbatterymaynotbeopened.
• Whenchangingauxiliarybatteries,useonlybatteries
of the same make and capacity.

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
dierent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.
