Dangers from
mains current
and charging cur-
rent
Anyone working with chargers exposes themselves to numerous dangers e.g.:
- Risk of electrocution from mains current and charging current.
- Hazardous electromagnetic fields, which can risk the lives of those using cardiac
pacemakers.
An electric shock can be fatal. Every electric shock is potentially life threatening. To avoid
electric shocks while using the charger:
- Do not touch any live parts inside or on the outside of the charger.
- Under no circumstances touch the battery poles.
- Do not short-circuit the charging lead or charging terminals.
All cables and leads must be secured, undamaged, insulated and adequately dimen-
sioned. Loose connections, scorched, damaged or inadequately dimensioned cables and
leads must be immediately repaired by authorised personnel.
Danger due to ac-
id, gases and va-
pours
Batteries contain acid which is harmful to the eyes and skin. During charging, gases and
vapours are released that may be harmful to health and are highly explosive in certain cir-
cumstances.
Only use the charger in well-ventilated areas to prevent the accumulation of explosive gas-
es. Battery rooms are not deemed to be hazardous areas provided that a concentration of
hydrogen of less than 4% can be guaranteed by the use of natural or forced ventilation.
Maintain a distance of at least 0.5 m (19.69 in.) between the battery and charger during the
charging procedure. Possible sources of ignition such as fire and naked flames must be
kept away from the battery.
The battery connection (e.g. charging terminals) must not be disconnected for any reason
during charging.
Do not inhale any of the gases and vapours released under any circumstances - Make sure
the area is well ventilated.
To prevent short circuits, do not place any tools or conductive metals on the battery.
Battery acid must not get into the eyes or onto the skin or clothes. Wear protective goggles
and suitable protective clothing. Rinse any acid splashes thoroughly with clean water and
seek medical advice if necessary.

General informa-
tion regarding the
handling of bat-
teries
- Protect batteries from dirt and mechanical damage.
- Store charged batteries in a cool place. Self discharge is kept to a minimum at approx.
+2 °C (35.6 °F).
- Carry out a visual inspection at least once a week or as often as specified by the bat-
tery manufacturer to ensure that the acid (electrolyte) level in the battery is at the max.
mark.
- If any of the following occur, do not start the device (or stop immediately if already in
use) and have the battery checked by an authorised workshop:
- uneven acid levels and/or high water consumption in individual cells caused by a
possible fault.
- overheating of the battery above 55 °C (131 °F).
Protecting your-
self and others
While the charger is in operation, keep all persons, especially children, out of the working
area. If, however, there are people in the vicinity,
- warn them about all the dangers (hazardous acids and gases, danger from mains and
charging current, etc.),
- provide suitable protective equipment.
Before leaving the work area, ensure that people or property cannot come to any harm in
your absence.
Safety measures
in normal opera-
tion
Chargers with a ground conductor must only be operated on a mains supply with a ground
conductor and a socket with a ground conductor contact. If the charger is operated on a
mains supply without a ground conductor or in a socket without a ground conductor con-
tact, this will be deemed gross negligence. The manufacturer shall not be held liable for
any damage arising from such usage.
Only operate the charger in accordance with the degree of protection shown on the rating
plate.
Never operate the charger if there is any evidence of damage.
Arrange for the mains cable to be checked regularly by a qualified electrician to ensure the
ground conductor is functioning properly.
Any safety devices and parts that are not functioning properly or are in imperfect condition
must be repaired by a qualified technician before switching on the charger.
Never bypass or disable protection devices.
After installation, an accessible mains plug is required.
