PowerSafe OPzV
Installation, operating
and maintenance instructions
No smoking no naked
flames, no sparks
Electrical hazard
Electrolyte is corrosive,
in case of broken
containers/lids
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.
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.
DELIVERY AND STORAGE
Inspect for signs of damage or missing
components.
Store the battery in a dry, clean and
preferably cool and frost-free location.
Do not expose the cells to direct sunlight
as damage to the container and cover
may occur. As the batteries are supplied
charged, storage time is limited. In
order to easily charge the batteries after
prolonged storage, it is advised not to
store it more than
12 months at 20°C
6 months at 30°C
3 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
service life.
The refreshing charge shall be carried
out according to clause a) of the
commissioning 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 battery installation must be in
accordance with the applicable rules
and regulations. Specifically EN 50272-2
applies.
Do not use terminal posts to lift or handle
cells.
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 sufficient for cooling
purposes and inadvertent overcharge,
Shield eyes
Danger
Clean all acid splash in eyes or
on skin with lot of clear water.
Then visit a doctor.
Acid on clothing is to be washed
with water.
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.
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
sunlight. Approved battery racks are
recommended 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 use terminal posts to lift or handle
cells.
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 damage to the plastic materials,
do not use grease. Fit the covers supplied
for protection against
contact.

Note operating
instructions
Warning: Risk of fire, explosion, or
burns. Do not disassemble, heat
above 60ºC, or incinerate. Avoid
any short circuit. Metallic parts
under voltage on the battery, do not place tools
or items on top of the battery
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.

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 charger switched off,
the battery fuses removed and the load
disconnected, connect the battery to the
D.C. power supply.
Ensure that the polarity is correct -
positive terminal of the battery to the
positive terminal of the charger. Switch
on the charger and charge according to
the commissioning charge paragraph
below. The
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 connected strings,
use batteries of the same capacity,
design and age only with a maximum 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
