This manual provides instructions for the

®
DDm
batteries that comply with EN 60896-21
& 22.
Batteries are often the last lines of defence
in providing electrical energy after failure of
the mains supply. This manual provides
information for optimising performance and
service life and should be read in
conjunction with EN 50272 together with the
appropriate Health & Safety Data Sheet.
This manual should be read immediately
upon receipt of the battery. Warranties are
only valid if the product has been installed,
commissioned, operated and maintained in
accordance with these instructions.
Particular care must be taken during the
handling and installation of lead-acid
batteries. Personnel undertaking this work
must be provided with appropriate
equipment to ensure their safety and in
addition to exercising routine care and
caution they should be additionally made
aware of the following:
• Acid - these batteries contain dilute
sulphuric acid which is poisonous and
corrosive. It can cause burns on contact
with skin and eyes. If acid is spilt on skin
or clothing wash with plenty of clean
water. If acid gets into eyes wash well with
plenty of clean water and get immediate
medical attention.
• Protective clothing - Always wear
protective clothing. Eye protection
(goggles or visor) should be worn if your
job brings you into contact with acid.
• Gases - Batteries can give off explosive
gasses. Keep sparks, flames and lighted
cigarettes away from the battery. Isolate
the battery circuit before connecting or
disconnecting the battery as otherwise a
spark can cause an explosion.
Ensure connections are all tight before
switching on and use insulated tools only.
Areas where batteries are kept or charged
must be adequately ventilated.
• Electricity - Use insulated tools only to
make connections to a battery. Check the
external circuit to ensure it is safe before
making a connection to the battery. Before
working on a battery, always remove
personal metal effects, such as rings,
watches, bracelets, necklaces, etc.
• Guidance documents - It is recommended
that copies of the following documents are
obtained and read in conjunction with this
manual:
• Health & Safety Information
for Lead-Acid Batteries - EnerSys Ltd.
• EN 50272-2 and IEC 62485-2 Safety
Requirements for Secondary Batteries
