7. Installation
Before installing, double check the
condition of each battery module.
Fx5 Size the correct
number of battery
modules to connect to
the DC bus.
Figure
3,4,5
Before installing, ensure the right
number of battery modules are
connected in series to support the DC
bus.
Fx6 Check for maximum of
2V difference between
battery modules
operating on the
same DC bus.
Figure
7
If battery modules have more than
2.0Vdc difference, then recharging is
necessary. Consult Saft for full
instructions.
Fx7 Connect the battery
modules.

Before system integration, verify that
all the components inside the cabinet
are correctly attached to the rack and
connected with relevant tightening
couples.
Full system installation and
commissioning may only be performed
by an engineer certified by Saft. This is
required to activate the system
warranty:
■■
■
Connect power cables between
BMM and Intelli-Connect.
■■
■
The power connections of the BMM
with the first and last battery modules
of each string are performed though
the HV terminals “VIN-BAT” and
“VIN+BAT” located on the BMM front
face (refer to Figure 6).
■■
■
The power connections of each
battery string, once assembled, are
performed through the HV terminals
“VOUT-DC” and “VOUT+DC” located
on the BMM front face (refer to
Figure 6).
■■
■
Connect Low Voltage cable (installed
in Cabinet) to BMM.
■■
■
Connect CAN bus cable between
battery modules and BMM.
■■
■
If the battery system comprises
multiple parallel strings, connect
BMM #01 communication port to
BMM#02, etc. (refer to Figure 6).
■■
■
Connect the MBMM signals to the
customer’s application (when
requested).
■■
■
Connect the electrical power cables
between battery modules, BMM and
Intelli-Connect using insulated tools.
■■
■
Connect the battery string to the dc
bus of the application. The power
connections of each battery module
are performed via the high voltage
(HV) “+” and “- “terminals located on
the front face. Personal protective
equipment is required.
Fx8 Power ON

■■
■
Reclose/reengage the circuit
breaker on each BMM.
■■
■
According to the configuration,
press the push ON/START button
on the front door of the master
cabinet (refer to Table 4).
Flex’ion®
IMPORTANT:
Never leave the Flex’ion® ON when it is
not in use. The internal electronics will
self-discharge the cells to a low voltage
alarm level which may render the
module un-usable.
8. Operation/Maintenance
Flex’ion provides uninterrupted standby
power anytime the AC power supply is
OFF. Continue trouble-free operation by
complying with these instructions.
Battery modules do not require regular
maintenance. Periodically checking the
complete Flex’ion system during other
site routines is recommended (more
details are available in the Operating &
Maintenance manual).
■■
■
LED state (refer to Table 4).
■■
■
Clean any excessive dirt build-up
using a nonmetallic brush or a dry
or damp cloth.
■■
■
Do not use any cleaning solvents or
soaps.
■■
■
Do not immerse, bathe or hose off
the Flex’ion system.
Charge and discharge of the Li-ion
battery must be monitored and
managed with respect to parameters
such as current, cell voltages and
module temperatures. This
management is performed by the
battery module at the cell level and
BMM at string level.
