BATTERY & COMMISSIONING

Taking Delivery of Your Battery

Do not carry out any of the following procedures
in a zoned area. Use special coding systems
for maintenance-free batteries for the charging
plug-and-socket devices to prevent accidental
connection to a wrong type of charger. The
possibility of the battery being connected in the
wrong polarity is prevented by visibly marking
the polarities adjacent to the connection plug
with an identification colour (Positive Red and
Negative Blue).
Commissioning
The charger cables must be connected to ensure
a good contact, ensuring that the polarity is
correct. Otherwise, the battery, vehicle, or
charger could be damaged. Wipe over the tops
and sides of the cells and container with a damp
cloth to remove dust and water. Cell cleanliness
cannot be too highly stressed. Check that all
connections are tight.
The specified torque loading for the pole screws
is 25 +2Nm (screw M10).
Make sure that the cells are readily accessible
for testing. This will make regular maintenance
hassle-free. Check that the battery compartment
is well drained and ventilated, and that there is
no risk of metal objects dropping through the top
ventilation of the battery. Check that the battery
sits quite firmly and securely in its housing, and

Maintenance

The electrolyte is immobilised in a gel. The density
of the electrolyte cannot be measured.
• Never refill with water!
• Never remove the safety valve from the cell in
case of accidental damage of the valve, contact
our After Sales Service Centre for replacement.
The possibility of the insulation on the overall
battery voltage leads being cut to expose the
conductor is prevented by sleeving the insulation
with cable retention material (i.e. spiral wrap).
Remove all packing material and carefully
examine the containers, etc. to ensure that there
is no physical damage.
If the battery is not used at receipt, please refer to
the Storage section on page 11.
use suitable packing to prevent any movement
when the vehicle is in motion. The cables should
be flexible and of sufficient length to prevent any
strain from being imposed either on the cable
or the certified terminals to which the cables are
connected. If a new Ex battery is to be used in
an application where there is uncertainty about
the zoned area, please contact your local factory
inspector. Never directly connect an electrical
appliance (for example, a warning beacon) to
some cells of the battery. This could lead to an
imbalance of the cells during the recharge, i.e. a
loss of capacity, the risk of insufficient discharge
time, or damage to the cells and this may AFFECT
THE WARRANTY OF THE BATTERY.
The battery is then charged as in the Recharge
section on page 9.
Daily
Recharge the battery after discharge.
• Remember, never charge an Ex battery in a
zoned area, even if approved charging equipment
is available. Always check that the charger is
operating correctly.
• Check that the plugs and sockets are in good
condition.
