IMPORTANT!
Ensure secure grounding of the grid connection.
Dangers due to
Grid and Char-
ging Current
Work with battery charging systems poses a number of dangers, such as:
-
electrical hazard due to grid and charging current.
-
hazardous electromagnetic fields that may pose a risk of death for individu-
als with pacemakers.
An electric shock can be fatal. Every electric shock poses a risk of death. To pre-
vent electric shock during operation:
-
do not touch any voltage-carrying parts inside or outside of the device.
-
never 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 di-
mensioned. Loose connections, scorched, damaged, or under-dimensioned
cables and leads must be repaired immediately by an authorized specialist.
Danger due to
Acids, Gases,
and Vapors
Batteries contain acids which pose a risk to the eyes and skin. Furthermore, char-
ging batteries produces gases and vapors that may be hazardous to your health
and are highly explosive under certain circumstances.
Only use battery charging systems in well ventilated rooms in order to prevent
the accumulation of explosive gases. Battery rooms are not considered at risk of
explosion if a hydrogen concentration of less than 4% is guaranteed by natural or
artificial ventilation.
During charging observe a minimum distance of 0.5 m (19.69 in.) between the
battery and charging system. Keep potential sources of ignition such as fire and
open flames away from the battery.
Never disconnect the battery (e.g., charging terminals) during charging.
Never breathe in the gases and vapors produced by the battery - Ensure there is
a sufficient supply of fresh air.
Do not place any tools or electrically conductive metals on the battery, in order
to prevent short circuits.
Never allow battery acid to come into contact with your eyes, skin, or clothing.
Wear eye protection and appropriate protective clothing. Rinse away any
splashed acid immediately and thoroughly with clean water, and consult a physi-
cian if necessary.
General informa-
tion on working
with batteries
-
Protect batteries from dirt and mechanical damage.
-
Store charged batteries in cool rooms. The lowest self discharge occurs at
approx. +2°C (35.6°F).
-
Refer to the specifications of the battery manufacturer or conduct weekly
visual inspections to ensure that the battery is filled with acid (electrolyte)
up to the maximum marking.
-
Do not start operating the device, or immediately stop operation, and have
the battery inspected by an authorized specialist if:
-
the acid level is uneven or there is high water consumption in individual
cells caused by a possible defect
-
the battery heats up to an impermissible level, above 55°C (131°F)
