3.5.2 Comet EXtreme 9 and 12 kVA
3.5.2.1 Check that the battery circuit breaker(s) is OFF.
3.5.2.2 Connect cable to the connectors of the UPS and battery modules.
Input and output voltage of the UPS must always be the same.
Comet EXtreme products are factory configured at 208VAC, 60Hz input and output.
4.0 Start-up Procedure
This document provides an overview of the initial procedures that should be followed
before any devices are powered by your Comet EXtreme UPS.
Refer to your Comet EXtreme User Guide for safety, installation, and troubleshooting
information.
4.1 Battery Scan Test
This procedure is a test for each battery to verify it is in basic working order. To verify
it holds a charge, batteries should be charged for several hours before testing battery
levels.
The protected equipment connected to the UPS can be energized, whether AC input
power is available or not.
Prior to initial start-up, check the UPS voltage settings. If the protected equipment
voltage is other than 208 V/60 Hz, the UPS settings must be modified using the "UPS
Driver" software. See User Manual for instructions.
4.1.1 Verify that all AC and DC connections, input and output, are secure.
4.1.2 Set the battery circuit breaker(s) to “ON”. The buzzer will sound three times.

4.1.3 Turn on external AC power.
4.1.4 Press the ON/OFF button 21 on UPS. After 30 seconds, LED 19 goes on. All
connected equipment is energized.
If LED 19 does not go ON, or if LEDs 11 ,
12 , 13 or 14 flash, there is a fault (refer to section 4.1 of User Manual).
4.1.5 LEDs 11 to 14 provide three different indications:
◗Remaining backup time in percent (in ON-LINE mode).
◗Percent load drawn by the protected equipment,
when button 15 is pressed.
◗Operating faults (flashing LED and beeps):
11 Overload
12 UPS fault
13 Battery fault
14 Excessive ambient temperature
4.1.6 Allow the battery packs to charge for at least 10 minutes.
4.1.7 Remove power from the Comet EXtreme UPS by setting the
AC main circuit breaker supplying power to the UPS to “OFF.”
4.1.8 Set all battery circuit breakers, EXCEPT one, to the “OFF” position.
4.1.9 Verify that the Output Power ON/OFF switch on the UPS is in the “ON” position.
4.1.10 After approximately 30 seconds, at least one of the four yellow LEDs on the front panel
of the UPS should be lit. Additionally, the Battery Input LED 20 , on the front panel of
the UPS should be lit. This will indicate that the battery pack is operational.
4.1.11 Activate the next battery, if system has more than one battery set, by setting its circuit
breaker to “ON”. Deactivate the battery that was tested previously by setting its circuit
breaker to “OFF”. The battery test LEDs should still be illuminated.
4.1.12 Repeat step 4.1.12 until all batteries have been tested. Any battery that fails to light at
least LED 1 may need to be charged for a minimum of 3 hours. Repeat the scanning
procedure. If the battery pack again fails to light at least LED 1, it should be replaced.
4.1.13 Restore power to the Comet EXtreme UPS by setting the AC mains circuit breaker
supplying power to the UPS to “ON.” And set all battery circuit breakers to the “ON”
position.

4.2 Power-Up Test
4.2.1 After performing the Battery Scan Procedure above, set all battery circuit breakers to
the “ON” position.
4.2.2 Allow the UPS to charge the batteries for at least 3 hours per battery pack. You may
use the UPS while the batteries charge, but the battery backup runtime will be reduced
until the batteries are fully charged.
4.2.3 Switch on the protected equipment, one load at a time. If the UPS beeps an alarm
when you start your equipment, the UPS may be overloaded.
4.2.4 The four LEDs on the right side of the front of the UPS show the percent of battery
capacity remaining. To verify the percentage of maximum load, depress the “Push for %
of load” button.
Successful completion of the procedures above will verify that the Comet EXtreme
UPS is properly configured and ready for use. Please refer to your user guide for
detailed information on the function of your UPS.
