10-30 Vehicle Care
A charging battery could emit
explosive gases, which is why it
is important to prevent sparks
close to the battery. When
batteries are reaching the end of
their life cycle, internal sparks
may occur.
Always provide for proper
ventilation during charging.
Avoid covering the charger.
Ensure that the mains cable is
not exposed to water.
Never charge a frozen battery.
Never charge a damaged
battery.
Never place the charger on top
of the battery when charging.
Connection to the mains supply
must be in accordance with the
national regulations for electrical
installations.
Check the charger cables prior
to use. Ensure that no cracks
have occurred in the cables or in
the bend protection. A charger
with damaged cables must not
be used.
Always check that the charger
has switched to maintenance
charging mode before leaving
the charger unattended and
connected for long periods. If the
charger has not switched to
maintenance charging within
72 hours, this is an indication of
an error. In such cases the
charger must be disconnected
manually.
If a battery fails during charging,
the charger's advanced
technology will take care of most
problems but some rare errors in
the battery could still exist. Don't
leave a battery connected to the
charger unattended for a longer
period of time.
Store and use the battery
charger out of the reach of
children and ensure that children
cannot play with the charger.
Batteries consume water during
use and charging. For batteries
where water can be added, the
water level should be checked
regularly. If the water level is low
add distilled water.
BATTERY TYPES AND SETTINGS
The charger is suitable for use with
the battery supplied in your vehicle.
If you replace the original battery,
observe the battery manufacturer's
guidelines. See which battery sizes
that the various charger models are
suitable for under TECHNICAL
SPECIFICATIONS.
