Total Saft SMRX Series User manual

Important recommendations
Never allow an exposed flame or spark near
the batteries, particularly while charging.
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.
1. Receiving the shipment
Unpack the battery immediately upon arrival.
Do not overturn the package. Transport seals
are located under the cover of the vent plug.
The battery is normally shipped filled and
ready for installation.
Make sure all items have been received by
comparing with the packing list.
Check for damage or electrolyte spillage.
Report any irregularities to the carrier and
to Saft.
Remove the plastic transport seals. The
battery must never be used electrically with
the plastic transport seal in place as this can
cause permanent damage.
The battery is ready for installation.
2. Storage
Store the battery indoors in a dry, clean, cool
location (0°C to +30°C / +32°F to +86°F).
Make sure that the transport seals remain in
place during storage.
SMRX Ni-Cd batteries
Installation and operating instructions
Do not store in direct sunlight or exposed to
excessive heat.
A battery delivered charged (80%) must not be
stored more than 3 months up to 30°C, or
more than 6 months up to 20°C (including
transport). If a charged battery has to be
stored for more than the durations and
associated temperatures mentioned above ,
discharge the cells at 0.2 C5Adown to 1V per
cell or less.
A battery delivered discharged and filled may
be stored for many years before it is installed.
If storage is required prior to commercial
service, clean and coat the metallic parts with a
thin layer of neutral vaseline or neutral
petroleum jelly grease approved by Saft. Leave
the battery in its transport case to protect from
dust, moisture and short circuits.
3. Installation
Remove the transport seals and close the vent
plugs.
3.1. Verify that cells are correctly interconnected
and that battery connection to the load is also
correct.
3.2. Check tightness of terminal connecting nuts.
Torque applied must be:
• 10 ± 2 N.m for cells SMRX 75 to 140
• 15 ± 2 N.m for cells SMRX 160 to 260
The connectors and terminal nuts should be
corrosion-protected by coating with a thin
layer of neutral vaseline or anti-corrosion oil
agreed by Saft.
3.3. Electrolyte
The electrolyte used is E41.
4. Commissioning
Caution: during constant charging operations,
the battery box must be open.
4.1. The cells are delivered 80%charged.
Charging and discharging should be done at
constant current.
For a battery stored less than 3 months at T<
+30°C, or less than 6 months at T< +20°C,
no charge/discharge operation is required
before use.
For a battery stored for more than 3months or
at T>+30°C, or more than 6 months at
T>+20°C :
June 2020
• Discharge the battery at 0.2 C5A down to an
average 1V per cell.
• Maintain the battery in open circuit during 8
hours or until the battery temperature is
between 10°C and 30°C.
• Charge the battery at 0.2 C5A for 8hours.
4.2. The cells are delivered discharged
Caution: even if the battery is discharged, there
remains a residual charge that may cause an
electric shock.
Charging and discharging should be done at
constant current.
For a batter placed into service immediately
after delivery or after less than one year of
storage:
•Constant current charge: charge the battery
at 0.2 C5A for 8 hours.
Caution: during constant current charging the
battery box must be open.
• Constant voltage charge: 1.55V/cell for
20hours with the current limited at 0.2C5A.
For a battery stored more than 1 year:
• Charge the battery at 0.2 C5A for 8hours.
• Discharge the battery at 0.2 C5A down to an
average 1V per cell.
• Maintain the battery in open circuit during 8
hours or until the battery temperature is
between 10°C and 30°C.
• Charge the battery at 0.2 C5A for 8hours.
The battery is ready for use.

Table A:
5. Charging in service
1.47 V/cell at +20°C (+68°F) with voltage
compensation:
-3 mV/°C/cell (-1.7 mV/°F/cell).
For higher charging voltages, consult your local
Saft representative.
Boost charge according to IEC62973-2.
6. Topping-up
Frequency of topping-up must be determined
for each battery. Topping-up shall be performed
after one year in order to determine the ideal
topping-up interval which depends on the
charging voltage and actual use of the battery.
Never let the electrolyte level fall below the
minimum level mark. Use only distilled or
deionized water to top-up.
The topping-up operation must be carried on
charged cells with a rest time of minimum 2
hours.
Batteries not equipped with a water filling
system (typical frequency of topping-up is
every 6 months):
• No electrolyte level measurement is necessary
if you use a Saft cell-topper, which allows the
correct level to be obtained by a simple nozzle
setting (see nozzle lengths in Table A). If a cell-
topper is not available, the electrolyte level
must be measured.
• Insert a transparent glass or plastic tube (alkali
resistant, 5 to 6 mm in diameter) vertically into
the cell vent until it touches the top of the
plates. Close the top end of the tube by
putting a finger on it and remove it from the
cell. The height of the liquid in the tube
indicates the electrolyte level.
Batteries equipped with water filling system
(typical frequency of topping-up is every 12
months):
• Remove transport seals and connect hydraulic
tubing between cells up to a maximum of 50
cells.
• Make sure that the tubes are completely
inserted for a good seal.
• The hydraulic connection of cells must be in
parallel to the electrical connection, in order
to avoid voltage differences of more than 1.2V
between two hydraulically connected cells.
• The hydraulic connection must be horizontal
in order to avoid siphoning.
• The water filling circuit output must not be too
close to electrical equipment, electrical circuit
and metallic structure.
• Water filling circuit input must be connected to
the self-closing inlet.
• After a check after the first year of use, topping-
up can be performed every 6 years (if the
annual average cell temperature is below 30°C
and the battery is used as a back-up battery)
by gravity or using adapted pump with a flow
rate of 0.7 l/min at a relative pressure of 0.3 bar
maximum.
7. Preventive maintenance
Maintenance operations (not including the
topping-up operation):
• Periodic maintenance should be carried out
at least every 5 years. For detailed
maintenance, please refer to the
maintenance manual of the battery.
• Keep the battery clean using only water. Do
not use a wire brush or solvents of any kind.
Vent plugs can be rinsed in clean water.
• Check the torque of all terminal screws. Coat
with DW33 anti-corrosion greasy film all the
terminal nuts and cell connectors.
• Check charger settings. It is very important
that the recommended charging voltage
remainsunchanged.High water consumption
of the battery is usually caused by improper
voltage setting of the charger.
8. Electrolyte
Do not change the electrolyte during the life
time of the cells.
9. Environment
To protect the environment all used batteries
must be recycled. Contact your local Saft
representative for information.
