This may affect a number device types in terms of:
-
Connection restrictions
-
Criteria with regard to the maximum permissible mains impedance
*)
-
Criteria with regard to the minimum short-circuit power requirement

at the interface with the public grid
see "Technical data"
In this case, the plant operator or the person using the device should check whether the
device may be connected, where appropriate by discussing the matter with the power
supply company.
IMPORTANT!
Ensure that the mains connection is earthed properly
The mains voltage tolerances of the devices may deviate from those specified in the
technical data depending on the mains connection.
Dangers from
mains current
and charging cur-
rent
Anyone working with battery 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 cable 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
acid, gases and
vapours
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
circumstances.
Only use the charger in well-ventilated areas to prevent the accumulation of explosive
gases. Battery rooms are not deemed to be hazardous areas provided that a concentra-
tion of hydrogen of less than 4% can be guaranteed by the use of natural or forced vent-
ilation.
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.
