9.3 12 V power supply
When the caravan is not connected to the 240 V power supply, 12 V power
supply is performed either by the starter battery of the connected towing
vehicle or by the living area battery (Power Pack SE). If the caravan is electri-
cally connected to the towing vehicle and the vehicle engine is running, the
living area battery is charged by the vehicle generator.
The 12 V power supply can be cut off with the 12 V main switch on the panel
(SE).
9.3.1 Living area battery, general (Power Pack SE)
If you use the battery of the towing vehicle to provide power for the caravan,
bear in mind that the battery capacity is restricted. If you place too great a
burden on the battery, this may lead to starting difficulties.
Always disconnect the electrical connection between the towing vehicle
and the caravan before the caravan is connected to a 240 V power supply.
In order to carry this out, disconnect the plug from towing vehicle socket.
Always disconnect the electrical connection between the towing vehicle
and the caravan before the living area battery is charged by means of a
charger.
To make the living area's electrical installation completely voltageless, pull
out the plug from the battery input "Batterie-Eingang" on the transformer/
rectifier.
Use the charger module provided on the transformer/rectifier to charge the
living area battery. When charging externally, use a regulated charger that
is suitable for the battery type (a lead acid or dryfill battery) and the capacity
of the living area battery.
Prior to commencing a journey ensure the living area battery is fully
charged. For this reason charge the living area battery for at least 20 hours
before commencing the journey.
During the trip, use every opportunity to charge the living area battery.
Charge the living area battery for at least 20 hours after the journey.
Charge the battery for at least 20 hours before laying up.
For long periods of inactivity (4 weeks or more), either disconnect the living
area battery or recharge it regularly.
When the living area battery is changed, only use batteries of the same
type. A dryfill battery may only be replaced by a dryfill battery.
When changing the living area battery, use only batteries which meet the
minimum capacity of the charger. Observe the separate instruction manual
for the charger. Lower-capacity batteries will generate a great deal of heat
when they are charged. Danger of explosion!
Before disconnecting or connecting the terminals of the living area battery,
switch off the engine of the towing vehicle as well as the 240 V and 12 V
power supplies and all appliances. Danger of short circuit!
If the living area battery is disconnected and the caravan and towing
vehicle are connected electrically, do not apply the ignition. Danger of short
circuit!
Take note of the battery manufacturer's users and maintenance instruc-
tions.
Only connect devices with a maximum of 10 A to the sockets of the 12 V
power supply.
