2.2 Checking equipment compatibility
Check that the UPS and CLA modules are compatible:
2.3 Batteries to be used
Use only 12 V / 65 Ah lead-acid batteries.
Connect them as indicated below to obtain the required backup time:
2. Installation
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, CLA and UPS modules must be installed in the same room as batteries so that the automatic
regulation of the charge voltage as a function of temperature can work correctly.

Use a 3-conductor cable (shielded, max.
length 6 m, 3 x 4 mm2conductors) to be
passed through the shielded cable gland.
Use a 25 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 plate and dismantle the
metal cable gland on the Comet EXtreme
CLA module.
3. Mount the cable gland on the shielded
cable.
4. Connect the 3 conductors to the terminal
block and refit the plate.
5. Connect the other end of the cable to the
circuit breaker.

Use a flexible cable (3 x 2.5 mm2
conductors) 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.

2.6 Connecting the UPS to the Comet EXtreme CLA module
Use the connection cable supplied with the
module.
2.7 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.
