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).
• 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 C
5
A 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 Rustilo DW330 or
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 inter-
connected 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 Rustilo DW330 or neutral vaseline
or neutral petroleum jelly 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.
