Operation via auxiliary battery
(self-sufcient package)
• Only accumulator batteries with
bound electrolytes (gel or AGM
batteries) may be installed in those
positions specied by the manufac-
turer.
• 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 con-
trol panel: see 07-13)
• Before disconnecting or connecting
the auxiliary battery, disconnect the
electric connection to the base vehi-
cle and switch off the 230 V supply,
the 12 V supply as well as all electri-
cal devices.
• Before replacing fuses you must rst
de-energise the charge controller.
• Before replacing a blown fuse you
must rst x whatever caused the
fuse to blow.
• Fuses may only be replaced by
fuses with the same fuse protection
value.
• Airing the charge controller insuf-
ciently will cause a reduction of the
charge current.
• The surface of the charge controller
casing may become 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 auxiliary battery will supply the electri-
cal system with 12 V DC voltage. Since the batte-
ry only has a limited capacity, the electrical de-
vices 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: 230 V
mains connection, generator of the base vehicle
or possibly a solar panel, whereby the source of
input with the highest input voltage supplies the
charge current for the connected battery.
