Comet EXtreme Installation

1. Remove modules from packaging. Inspect for damage. Do not use damaged modules. If the system has a
transformer, inspect terminal blocks for damage.
2. Remove cables and I/O Box from packaging. Inspect for damage, especially the connection points. Insure
that connectors are not pinched or damaged in any way.
3. Place modules together for installation as shown in figures and wiring diagrams in this section.
4. Ensure that battery circuit breakers are off. Install battery cables to battery packs. Do not force or pinch
cables. This can cause damage to the UPS.
5. Have an electrician install the AC line input cables to the input side of the I/O Box as described in this section.
I/O Box should not be attached to the UPS while the AC connections are being made to the I/O terminals.
Ensure that input is connected to the input side of the I/O Box terminal block as shown in this section.
6. Turn on external AC line voltage. Measure voltage from L1 to L2. Should be 208 VAC or 240 VAC nominal.
Measure voltage between L1 and Ground and L2 and Ground. Should be 120 VAC nominal. Turn off external
AC line voltage.
7. Place the Manual Bypass Switch in the Normal position. Install I/O Box to the back of the UPS unit. Insure
that the I/O Box connector lines up properly with the UPS. Push on the I/O Box to insure that it fits
tightly. Secure I/O Box to the UPS unit using a #8 Torque tool. Do not attempt to install I/O Box using a tool
other than Torque.
8. Connect battery cable (s) to UPS unit. Insure that the connectors line up properly. Do not pinch connectors
or force them in.
9. Check the front of the UPS unit and insure that none of the buttons are pushed in. Check the " ON/OFF "
button to insure that it is out, not pushed in.
10. Turn on battery circuit breaker(s). You will hear 3 short beeps indicating that the UPS unit has detected the
battery voltage.
11. Wait 60 seconds to ensure that the top four amber LEDs illuminate on the UPS. When the four amber LEDs
"11 through 14" are illuminated, turn on the input AC line voltage. With the AC input present, the four amber
LEDs represent battery charge level. At this time the four amber LEDs will change as follows; normally two
or three LEDs will illuminate and then the third and forth will illuminate. This will take approximately 30 to 60
seconds. Wait 60 seconds to ensure that 4 LEDs are illuminated.
12. UPS can now be turned on. Please read the "Operation" section for UPS start-up instructions.
CAUTION
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.
NOTE
Both AC and DC power are required to start Comet
EXtreme UPS. If Electronic module is configured
for cold start, then AC and DC are required for
initial start-up only.
