The battery room should be well ventilated in order to remove gases produced during charging. The gases (a mixture of
oxygen and hydrogen) liberated by the cells when on charge may cause an explosion, and therefore, care must be taken
not to produce sparks. Naked lights and smoking are not allowed.
The following precautions must also be taken:
During maintenance operations, do not wear clothing likely to create static electricity (for example nylon).
Do not use portable apparatus linked to an electric plug.
All installation practices and ventilation requirements must comply with EN 50272-2 and IEC 62485-2 standards and
national regulations.
6. Safety
Safety precautions
Batteries give off explosive gasses. They are filled with dilute sulphuric acid, which is very corrosive. When working
with sulphuric acid, always wear protective clothing and glasses. Exposed metal parts of the battery always carry a
voltage and are electrically live (risk of short circuits). Avoid electrostatic charge. The protective measures according
to EN 50272-2 must be observed.
Note operating
instructions.
When working on
batteries, wear safety
glasses and
protective clothing.
No smoking. Do not
allow naked flames, hot
objects or sparks near
the battery, due to the
risk of explosion or fire.
Danger. Cells are heavy.
Make sure they are
safely installed. Only use
suitable transport and
lifting equipment.
Electrical hazard.
Electrolyte is highly
corrosive.
Risk of explosion and fire.
Avoid short circuits.
Wash all acid splash in
eyes or on skin with
plenty of clean water and
seek immediate medical
assistance.
Recycling and disposal of used batteries
Used batteries contain valuable recyclable materials. They must not be disposed of with the
Domestic waste but as special waste. Modes of return and recycling shall conform to the
prevailing regulations in operation at the site where the battery is located.
Warranty
Any of the following actions will invalidate the warranty -
Non-adherence to the Installation, Operating and Maintenance instructions. Repairs carried out with non-approved
spare parts. Application of additives to the electrolyte. Unauthorised interference with the battery.
Handling
Vented lead acid batteries are supplied in a
moist charged state and must be unpacked
carefully to avoid short-circuit between
terminals of opposite polarity. The cells are
heavy and must be lifted with appropriate
equipment.
Discharge any possible
static electricity from
clothes by touching an
earth connected part.
Tools
Use tools with insulated handles.
Do not place or drop metal objects onto
the battery. Remove rings, wristwatch
and metal articles of clothing that might
come into contact with the battery
terminals.
