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.
Electrical hazard
Danger
Recycle scrap
batteries.
Contains lead
Electrolyte is corrosive,
in case of broken
containers/lids
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.
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
flammable 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
articles 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.
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
IEC 62485-2 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,
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
inadvertent contact.
Tab. 1: Torque loadings for terminal screws
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 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 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.
