DELIVERY AND STORAGE
Inspect for signs of damage or missing
components.
Store the battery in a dry, clean and prefe-
rably cool and frost-free location. Do not
expose the cells to direct sunlight as dama-
ge to the container and cover may occur.
As the batteries are supplied charged, sto-
rage time is limited. In order to easily char-
ge the batteries after prolonged storage, it
is advised not to store it more than
6 months at 20°C
4 months at 30°C
2 months at 40°C
A refreshing charge shall be performed
after this time or if the open circuit voltage
is below 2.07 Vpc.
Failure to observe these conditions may
result in greatly reduced capacity and ser-
vice life.
The refreshing charge shall be carried out
according to clause a) of the commissio-
ning charge paragraph below. Alternatively
the cells can be float-charged at 2.25 Vpc
during storage.
INSTALLATION
The electrical protective measures and the
accommodation and ventilation of the bat-
tery installation must be in accordance with
the applicable rules and regulations.
Specifically EN 50272-2 applies.
The battery should be installed in a clean,
dry area. It will not emit corrosive gases in
normal operation and can be installed
together with other electrical equipment.
Under normal conditions the gas release is
negligible and natural ventilation is suffi-
cient for cooling purposes and inadvertent
overcharge, enabling OPzV batteries to be
used safely in offices or within equipment.
However care must be taken to ensure
adequate ventilation when placed in
cabinets. They must not be placed in sealed
cabinets without ventilation openings at
the top and bottom.Avoid placing the
battery in a warm place or in direct sun-
light. Approved battery racks are recom-
mended for proper installation. Place the
cells on the rack and arrange the positive
and the negative terminals for connection
according the wiring diagram.
Horizontal Installation
Do not install the cells in such a way that
the box-lid bond is resting on a runner.
Ensure that the internal plates are vertical.
Check that all contact surfaces are clean. If
required clean with a brass brush. Tighten
the terminal screws, taking care to use the
correct torque loading (Tab. 1). To avoid
damage to the plastic materials, do not use
grease. Fit the covers supplied for protec-
tion against inadvertent contact.

Type Terminal screw Torque
OPzV M10 23 – 25 Nm
Carefully follow the polarity sequence to
avoid short circuiting cell groups. A loose
connector can make adjusting the charger
difficult, create erratic performance and
possible damage to the battery and/or
even personal injury. Finally, with the char-
ger switched off, the battery fuses remo-
ved and the load disconnected, connect
the battery to the D.C. power supply.
Ensure that the polarity is correct - positi-
ve terminal of the battery to the positive
terminal of the charger. Switch on the
charger and charge according to the com-
missioning charge paragraph below. The
first charge must be monitored to ensure
that the limits are not exceeded and that
no unacceptable temperatures occur.
Cells or monoblocs in parallel strings
OPzV cells monoblocs may be connected
in parallel to give higher current
capability. In the case of parallel connec-
ted strings, use batteries of the same
capacity, design and age only with a maxi-
mum of 4 parallel strings. The resistance
of the cables in each string must be the
same, e.g. same cross-section, same
length. Connect the battery strings in
parallel at the charger terminals.
Handling
OPzV batteries are supplied in a fully 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.
Keep Flames Away
In the case of an accidental overcharge, a flam-
mable gas may be emitted from the safety valve.
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 arti-
cles of clothing that might come into contact
with the battery terminals.
Warranty
Any of the following actions will invalidate the warrranty - 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.

Do not install the cells in such a way that the
box-lid bond is resting on a runner. Always
ensure that the arrow on the lid of each unit
is pointing in vertical orientation.
Do not invert cells (vents upside down) or
allow the front of the cells to be positioned
lower than the base of the cell as it might
block the safety valve and damage pillars.
Check that all contact surfaces are clean. If
required clean with a brass brush. Tighten
the terminal screws, taking care to use the
correct torque loading (Tab. 1). To avoid
