This operation may be carried out only by qualified electricians using the
necessary safety equipment for work on live parts (insulated tools,
gloves, goggles).
The connection of each module to the electrical supply
must be protected by an easily accessible circuit breaker
(not supplied). A module can be isolated from the
electrical supply by opening this circuit breaker.
Before making any connections or working on the
equipment, make sure the battery circuit breaker is in OFF
position and that the main contacts of the upstream
protective devices of the electrical installation are open
(OFF position).
For maximum battery life, Comet EXtreme CLA modules must be
installed in the same room as the UPS so that the automatic regulation
of the charge voltage as a function of temperature can work correctly.
Two cables exit the connection box. Do not modify the length of these
cables. Each of these cables must be connected to a Comet EXtreme
CLA module as indicated below.
1. Unscrew the plate and dismantle the metal cable glands on the
Comet EXtreme CLA modules.
2. Cut and remove the retainers on the shielded cables of the connection
box.
3. Mount the cable glands on the shielded cables.
4. Connect the 3 conductors of each cable and remount the plate.

Page 6 - 51033777EN/AB
2.5 Connecting the batteries to the connection box
Use a 3-conductor cable (shielded, max.
length 6 m, 3 x 10 mm2conductors) to be
passed through the shielded cable gland.
Use a 50 A circuit breaker
(curve B) for protection.
Note: the cable and circuit breaker are not
supplied with the product.
1. Prepare the cable.
2. Unscrew the cover and dismantle the
metal cable gland of the connection box.
3. Mount the cable gland on the shielded
cable.
4. Connect the 3 conductors to the terminal
block and refit the connection box cover.
5. Connect the other end of the cable to the
circuit breaker.
2.6 Connecting the Comet EXtreme CLA modules to the power source
Use flexible cables (3 x 2.5 mm2conductors)
to be passed through the plastic cable
gland.
Always connect the earth wire
first. Use a 10 A circuit breaker
(curve C) for protection.
Note: the cable and circuit breaker are not
supplied with the product.
1. Prepare the cable.
2. Unscrew the plate with the plastic cable
gland.
3. Connect the 3 conductors and remount
the plate.

2.7 Connecting the UPS to the two Comet EXtreme CLA modules
Use the connection cables supplied with the
modules.
2.8 Setting the UPS
Before connecting the loads to be protected
and starting the system, the UPS must be
reconfigured using the UPS Driver software
supplied on a diskette with the UPS.
1. Switch the battery circuit breaker to ON
position.
2. Connect a PC to the UPS using an RS232
cable.
3. Run the UPS Driver software installed on
a diskette. Go to the "battery" menu and
select the battery backup time (2, 4 or 8
hours) corresponding to the new
configuration.
Once the backup time has been set, click to
save the settings and exit UPS Driver. This
procedure is necessary for fast recharge of
the batteries by the Comet EXtreme CLA.
The installation is now ready and you can
connect the equipment to be protected.
