The living area battery may not be opened.
Use only the built-in transformer/rectifier to load the living area battery.
In order to do this, connect the 230 V connection (CEE connector) of the
vehicle to an external 230 V power supply.
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.
After the trip, charge the living area battery fully.
Before a temporary lay-up, charge the battery fully.
When the living area battery is changed, only use batteries of the same
type and the same capacity.
When changing the battery, always disconnect the negative pole first
and, then, the positive pole. When connecting, proceed in inverted order:
connect the positive pole first and, then, the negative pole.
When changing batteries, use only batteries for which there are charging
characteristics available. After changing the battery the charging charac-
teristics must be adjusted at the transformer/rectifier or at the auxiliary
charging unit.
If several lead batteries are present, change all lead batteries. The bat-
teries must always be the same age and have the same capacity.
After a battery change, have the battery voltage indicators checked by
an authorised specialist workshop / service centre.
When changing batteries, 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!
If a
HYMER
Smart Battery System is installed, the lead batteries in-
stalled must have a minimum capacity of 95 Ah.
If the living area battery is replaced and the charging unit does not pro-
vide at least 10 % of the rating of a new battery, install an auxiliary
charging unit. Example: With a battery capacity of 80 Ah, the charging
unit must supply at least 8 A charging current.
Before disconnecting or connecting the terminals of the battery, switch
off the vehicle engine as well as the 230 V and 12 V power supplies and
all appliances. Danger of short circuit!
If the starter battery or living area battery are disconnected, do not apply
the ignition. There is a danger of short circuit from exposed cable ends.
If there are two living area batteries: When changing, ensure that the
batteries are properly installed. Install the batteries so that the positive
terminal on one battery is lying next to the negative terminal of the other
battery.
If there are two living area batteries: When changing, ensure that the
batteries are properly connected (see Installing the auxiliary battery).
