Important recommendations
■
WARNING: Risk of fire, explosion,
or burns. Do not disassemble,
heat above 70°C, or incinerate.
■
Never smoke while performing any
operation on the battery.
■
For protection, wear rubber gloves,
long sleeves, and appropriate
splash goggles or face shield.
■
The electrolyte is harmful to skin
and eyes. In the event of contact
with skin or eyes, wash immediately
with plenty of water. If eyes are
affected, flush with water, and
obtain immediate medical attention.
■
Remove all rings, watches and
other items with metal parts before
working on the battery.
■
Use insulated tools.
■
Avoid static electricity and take
measures for protection against
electric shocks.
■
Discharge any possible static
electricity from clothing
and/or tools by touching an
earth-connected part "ground"
before working on the battery.
■
Ventilation, in accordance with the
IEC 62485-2 standard, is
mandatory during commissioning
and operation.
1. Receiving the shipment
Unpack the cells immediately upon
arrival. Check the packages and cells
for transport damage. The cells are
normally shipped filled, discharged and
are ready for assembly.
2. Storage
Store the cells indoors in a dry, clean
and cool location (0°C to +30°C /
+32°F to +86°F).
■
Do not store in unopened packing
crates. The lid and the packing
material on top of the cells must
be removed.
■
Do not store in direct sunlight or
exposed to excessive heat.
■
Cells delivered filled and discharged
may be stored for many years before
they are installed.
■
Cells delivered charged must not
be stored more than 3 months
(including transport).
SPH Ni-Cd batteries
Installation and operating instructions
3. Installation
3.1. Location
Install the battery in a dry and clean
room. Avoid direct sunlight, strong
daylight and heat.
The battery will give the best perfor-
mances and maximum service life
when the ambient temperature is
b10°C to +30°C (+50°F to
+86°F).
3.2. Mounting
Verify that cells are correctly
interconnected with the appropriate
polarity and with the connectors are
correctly torque.
The battery connection to load should
be with nickel plated cable lugs.
Recommended torques for connecting
nuts are:
M10 = 10+/- 2 N.m (88 in/lbs +/- 16 in/lbs)
M12 = 15+/- 2 N.m (133 in/lbs +/- 16 in/lbs)
The connectors and terminal nuts
should be corrosion-protected by
coating with a film of neutral vaseline.
Install the IP2X protections according
to the assembly instructions in
Appendix A to have the battery
compliant to IEC 62485-2/
EN 50272-2 standards for IP2X level
protection against electrical shocks.
3.3. Ventilation
During charging, the battery is emitting
gases (oxygen and hydrogen mixture).
Ventilation of the battery room, in
accordance with the IEC 62485-2
standard and local regulations.
3.4. Electrolyte
The electrolyte to be used is: E4
When checking the electrolyte levels,
a fluctuation in level between cells is
not abnormal and is due to the
different amounts of gas held in the
separator of each cell. The level should
be at least 15 mm above the minimum
mark (lower) and there is normally no
need to adjust it.
When the cells are charged, the
electrolyte level can be above the
maximum level mark (upper).
4. Commissioning
Verify that ventilation, in accordance
with the IEC 62485-2 standard,
is provided during this operation.
A good commissioning is important.
Charge at constant current is preferable.
If the current is limit lower than
indicated in the table A, charge for a
proportionally longer time.
After commissioning, the battery shall
be charged permanently according to
section 5.
Prior and during commissioning
charge, record all data requested in
the commissioning report available on
www.saftbatteries.com.
■
For filled and discharged cells
stored up to 1 year,
a commissioning charge is not
required and the cells are ready for
immediate use. 90% state of charge
is reached within 10 hours after
placed in service. If full performance
is needed immediately a
commissioning charge as described
in the following section is necessary.
■
For filled and discharged cells
stored for more than 1 year, a
commissioning charge is necessary:
• Constant current charge:
charge for 8 h at 0.2 C
5
A.
When the charger maximum voltage
setting is too low to supply constant
current charging, divide the battery
into two parts to be charged
individually.
• Constant voltage charge:
1.50 V/cell minimum for 24 h with
current limited to 0.2 C
5
A, or for
48 h with current limited to 0.1 C
5
A.
■
For filled and charged cells stored
for more than 3 months (including
transport), or if cells have been
stored for a few years or show
difficulties in recovering
performance, constant current
charging becomes necessary and
the following values are
recommended:
a) 15 h charge at 0.2 C
5
A
b) Discharge at 0.2 C
5
A down to
1.0 V/cell
c) 8 h charge at 0.2 C
5
A
d) The battery is ready for use.
