Fronius Selectiva 4.0 - Dangers Due to Grid and Charging Current; Danger Due to Acids, Gases, and Vapors

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 individuals with
pacemakers.
An electric shock can be fatal. Every electric shock poses a risk of death. To prevent
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 dimen-
sioned. 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, charging
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 accu-
mulation 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 suffi-
cient 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 immedi-
ately and thoroughly with clean water, and consult a physician if necessary.
