Important
Please read this manual immediately on receipt of battery before unpacking and installing. Failure to comply with these instructions will render any warranties
null and void.
Care for your safety
No smoking, no naked flames, no
sparks
Electrical hazard
Electrolyte is corrosive
Handling
PowerSafe
V batteries are supplied in a fully
®
charged state and must be unpacked carefully
to avoid very high short-circuit currents between
terminals of opposite polarity. Use lifting hooks
compatible with the plastic handles on the cell/
monobloc.
Unpacking
It is advisable to unpack all the cells or monoblocs and accessories before
commencing to erect and not to unpack and erect cell by cell.
All cells/units should be handled carefully, as the plastic container can be
damaged or broken if allowed to fall. Under no circumstances should they
be lifted by their terminal pillars.
All items should be carefully checked against the accompanying advice
notes to ascertain if any are missing and also inspected to see whether any
are damaged or broken. Should this happen the Sales Department should be
consulted.
Transit insulation covers are fitted to one pole or a one rigid plastic insulating
cover is provided which totally protects the unit terminals. These are factory
fitted to all products of the range and there is no need to remove them until
access to the terminals is required.
Storage
Store the batteries in a dry, clean and preferably cool location.
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
batteries for more than:
• 6 months at 20°C
• 3 months at 30°C
• 1.5 month at 40°C
A refreshing charge shall be performed after this time at 2.27-2.30Vpc at 20°C
for 48 to 96 hours. A current limit is not essential, but for optimum charge
efficiency the current output of the charger can be limited to 10% of the 3 hour
capacity rating. The necessity of a refreshing charge can also be determined
by measuring the open circuit voltage of a stored battery. Refreshing charge is
advised if the voltage drops below 2.10Vpc. Failure to observe these conditions
may result in greatly reduced capacity and service life.
Installation
Install batteries in a clean and dry area. PowerSafe V battery products
release minimal amounts of gas during normal operation (gas recombination
efficiency ≥ 95%). Batteries must be installed in accordance with national
standards (for instance EN 50272-2), otherwise in accordance with the
manufacturer's instructions.

Shield eyes
Danger
Clean all acid splash in eyes or on skin
with plenty of clean water.
Then seek medical help.
Acid on clothing is to be washed with
water
Keep flames away
In case of accidental overcharge a flammable gas
can leak off the safety vent.
Discharge any possible static electricity from clothes
by touching an earth connected part.
Temperature
n
Avoid placing the battery in a hot place or in front of a window.
The battery will give the best performance and service life when working at
a temperature between 20°C and 25°C. The usual operating temperature is
between -10°C and +45°C. Limits are comprised between -30°C and +45°C.
Ventilation
n
Under normal conditions gas release is very low and natural ventilation
is sufficient for cooling purposes and inadvertent overcharge, enabling
PowerSafe V batteries to be used safely in offices and with main equipment.
However care must be taken to ensure adequate ventilation when placed in
cabinets. Batteries must not be placed in close cabinets.
Mounting
n
Enersys
cells. Assemble the rack according to instructions. Place the battery blocks
or cells on the rack and arrange the positive and the negative terminals for
connection according to the wiring diagram. Check that all contact surfaces
are clean and apply the block or cell connectors and the terminal screws.
Tighten the screws securely. Finally connect the battery terminals. It is
important that the battery is mounted firmly.
Torque
n
Tighten the nuts or bolts to the recommended levels of fastening torque
as specified on the product label. A loose connector can cause problems in
charger adjustment, erratic battery performance, possible damage to the
battery and/or personal injury. Finally fix the connector covers.
Cell strings connected in parallel
Using constant voltage chargers and ensuring that the connections made
between the charger and the batteries have the same electrical resistance,
no special arrangements have to be made for batteries in parallel.
Although no special circuit arrangements are required, where the parallel
connection is made at the charger or distribution board, to avoid out of step
conditions, the bus bar run length and the area of cross section should be
designed so that the circuit resistance value for each of the strings is equal
within limits ± 5%.
Read 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 on the battery.
Remove rings, wristwatch and articles of clothing
with metal parts that may come into contact with
the battery terminals.
battery racks or cabinets are recommended when installing the
®
Re-cycle scrap batteries.
