Devices with a higher rating may affect the energy quality of the mains due to
their current input.
This may affect a number of 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.
NOTE! Ensure that the mains connection is earthed properly
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 threaten-
ing. 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 charger lead or charging terminals
All cables and leads must be secured, undamaged, insulated and adequately
dimensioned. Loose connections, scorched, damaged or inadequately dimen-
sioned cables and leads must be immediately repaired by authorised person-
nel.
Batteries contain acid which is harmful to the eyes and skin. During charging,
gases and vapours are released that can harm health and are highly explosive
in certain circumstances.
- Only use the chargers in well ventilated areas to prevent the accumulation
of explosive gases. Battery areas are not deemed to be hazardous areas
provided that a concentration of hydrogen of less than 4 % can be guar-
anteed by the use of natural or forced ventilation.
- Maintain a distance of at least 0.5 m (19.69 in.) between battery and
charger during the charging procedure. Possible sources of ignition, such
as fire and naked lights, must be kept away from the battery
- The battery connection (e.g. charging terminals) must not be disconnect-
ed for any reason during charging
- On no account inhale any of the gases and vapours released
- Make sure the area is well ventilated.
- To prevent short circuits, do not place any tools or conductive metals on
the battery
