MSX MSX70 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. MSX batteries are
shipped filled with electrolyte and no topping-
up of the electrolyte has to be performed upon
reception of the battery.
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
Saft.
Never operate the battery with colored
transport seals inserted on the outlet and
inlet of each module as this will damage
permanently the battery.
2. Storage
Store the battery indoors in a dry, clean, and
cool location (0°C to +30°C/ +32°F to +86°F).
MSX Ni-Cd batteries
Installation and operating instructions
Make sure that the plastic strapping and front
plates remain in place during storage (for
blocks delivered without metallic frames).
Do not expose to direct sunlight or 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 block battery at 0.2 C5A down 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.
3.1.Battery configuration varies depending on
the requirement.
Block battery directly fitted inside a battery
box.
Block battery to be installed by customer in
battery box designed by Saft. In this case, the
block battery is delivered with two front plates
and plastic strapping used for shipment and
handling. Front plates and plastic strapping
must be removed just before battery
installation. Don’t remove the front plates and
plastic strapping if the battery is stored.
Block battery to be managed directly by the
customer. In this case the block batteries are
delivered in light self-keeping cradles. Never
remove this assembly.
3.2.Verify that cells are correctly interconnected
and battery is correctly connected to the load.
3.3.Check torque of terminal connecting
screws.
Torque must be: 10 ± 2 N.m.
Connections and terminal screws must be
protected against corrosion by coating with a
thin layer of DW33 anti-corrosion greasy film.
4. Water filling system
installation
Remove transport seals and connect
hydraulic tubing between block battery
according to the battery drawing delivered
by Saft.
Saft’s water Filling Systems follows specific
rules, please respect carefully Saft’s battery
drawing for installation.
Make sure that the pipes are completely
inserted to ensure a good tightness.
Hydraulic connection of cells is in parallel to
the electrical connection in order to avoid
voltage differences of more than 1.2V
between two cells connected by this method.
The hydraulic connection must be horizontal
in order to avoid any siphon.
The water filling circuit outlet must not be
located close to electrical equipment and
electrical circuit or metallic structure.
Water filling circuit input must be connected
to the self-closing inlet.
When installed, check the water filling circuit
for continuity (no obstruction) and tightness
(no leaks) using a pressure test (a kit may be
supplied by SAFT).

5. Commissioning
Caution: during constant current charging
operations, the battery box must be open.
5.1.The batteries 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, 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. Discharge the battery
at 0.2 C5A down to an average 1V
per cell.
5.2.The batteries 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.
6. 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.
7. Topping-up
Before topping up operation, the water filling
circuit of the battery must be checked for
tightness (no leaks) using a pressure test (a kit
may be supplied by SAFT).
Use only distilled and deionized water for
topping-up.
Connect distilled water tank to the self-
closing inlet. Topping-up is completed when
an excess of 1 litre of water is measured at the
outlet of the water filling circuit.
Topping-up can be performed by Saft’s
gravity kit or by using Saft’s water filling
stations.
If charge at constant current: operation must
be carried on charged cells with a rest time of
minimum of 2hours.
If charge at constant voltage on the train, the
topping-up can be carried out at any time.
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.
8. Preventive maintenance
In addition to the topping-up, a periodic
maintenance shall be carried out up to every
10 years if the annual average cell temperature
is below 30°C and the battery is used as a
back-up battery.
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.
Check torque of all terminal screws. Coat
with DW33 anti-corrosion greasy film all
terminal screws and connections.
Check charger settings. It is very important
that the recommended charging voltage
remains unchanged. High water
consumption by the battery is usually
caused by improper voltage setting of the
charger.
It depends on the charging voltage and
actual use of the battery. Refer to section 7
concerning topping-up.
9. Electrolyte
Do not change the electrolyte during the life
time of the cells.
10. Environment
To protect the environment all used batteries
must be recycled. Contact your local Saft
representative for information.
