5. Transportation
Use the original packaging or
equivalent. Follow the necessary
transportation rules for Li-ion
batteries by consulting with your
company’s standard practice and
your local transportation regulations.
Secure the Evolion
®
to prevent violent
shock and other items from falling
onto it. The Evolion
®
must be OFF
during transportation.
6. Installation
See Figure 4 for Evolion
®
features.

IMPORTANT:
A reverse connection
on the power terminals may cause
an internal fuse fault. See Section
10 if replacing the fuse is necessary.
Connect communication
See Table 4 for RJ45 jack pin
assignments.
Table 4 - RJ45 pin assignments
Both RJ45 jacks are interchangeable
and can be used to plug either the
communication cable (772518) or
the RJ45 resistor cap (773455).
To access the dry contact alarm
signal, use pins 7 and 8. Both minor
or major alarm signals are reported
and the default state of the pin is as
follows:
CLOSED = ALARM/power down
OPEN = NO ALARM
Use the communication cable
provided. See Figures 7 and 8.
Make sure to conduct an Evolion
®
Installation and Commissioning
(I&C) prior to startup. Setting a
unique node ID (default = 1) for
each parallel connected Evolion
®
is
necessary in order to communicate
using the Saft Evolion
®
Toolbox
software during operation.
IMPORTANT:
Never connect the
power terminals in series with other
Evolion
®
units. The Evolion
®
may be
damaged and rendered inoperable.
IMPORTANT:
Parallel connecting can
be done as long as the total system
discharge current never exceeds
130 A (5 kW at 42 V) continuous.
In this case paralleling any number of
units is allowed.
Make sure to never parallel connect
Evolions that have more than 2 V
difference between the modules.
Equalizing the voltage by charging or
discharging modules separately may
be necessary. To check the open
circuit voltage when disconnected,
press the ON/OFF button for at
least 2 seconds and measure the
voltage at the terminals. Make sure
to turn the unit OFF by pressing
the ON/OFF button for at least 4
seconds.
The Evolion
®
limits its own current
with a built in charge regulated
circuit. However, starting up
the Evolion
®
to avoid the charge
regulated mode is important to avoid
a possible internal fuse fault.
Make sure to switch off the battery
breaker(s) before connecting Evolion
®
power terminals to the power bus.
The Evolion
®
power terminals can be
connected to systems with a positive
ground, a negative ground or a
floating ground system.
In order to prevent reverse connections,
make sure to measure and note the
polarity of the power bus cables.

Required tools
• 10 mm socket (for terminal)
• Multimeter (60 Vdc, ohms)
• Flat screwdriver (for cover removal)
• 7 mm socket (for fuse)
• Torque wrench (insulated)
Connect power
Always connect the Evolion
®
using
the provided cables in order to
balance the resistance in each
branch. See Figures 5 and 6 for power
connections schematics and options.

Figure 6 - Parallel connecting Evolions
OPTION 1 - For any
number of
parallel
chained
Evolions,
take off the power
bus connection
at the end of the
parallel connected
system. This is the
best way to balance
the resistance of
each.
NOTE: Can only be
used when the total
continuous bus
current is less than
or equal to 63 A.
OPTION 2 - For any
number of
direct
connected
Evolions,
using the same
length of cable
for each will make
sure to balance the
resistance.
Figure 5 - Connecting to terminals
• Only use the terminal bolts, washers,
terminal protectors and cable lugs
provided.
• Terminal bolt torque = 6 N.m (53 in.lbs)
