1. Confirm that the UPS system is properly grounded.
2. Make sure the utility AC supply circuit breaker and the UPS system’s input breaker are switched off.
3. Wire the utility AC supply circuit and output circuit to the UPS system’s terminal block and connect the external battery pack, following the
instructions in
Section 5 – Wiring
.
4. Switch on the utility AC supply circuit breaker and the UPS system’s input breaker. The green line LED (
) illuminates continuously to
indicate the utility-supplied AC line voltage of the AC supply circuit is nominal.
5. If the UPS system is operating in a parallel redundancy configuration, the LCD screen will display
A1
then
A2
then
B
. If the UPS system is
operating in a standalone configuration, the LCD screen will display
A1
then
B
.
6. The UPS system is now in bypass mode and will automatically proceed to the UPS system self-test.
7. If there are no abnormal/fault/error messages, the pre-startup of the UPS system has been successful and the battery charger begins to
charge the external battery pack.
8. Press the ON button
for approximately 3 seconds, then release it. The UPS will beep twice and the LCD screen will change from
B
to
C
.
9. The UPS system will perform another self-test, and the LCD screen will change from
C
to
D
and switch to battery mode for approximately
4 seconds. If the self-test is successful, the LCD screen will change to
E1
, then
F
. If the self-test is unsuccessful, the LCD screen will
change to
E2
, then an error code will be shown. If an error code is shown, refer to
Section 9 – Troubleshooting
.
10. If the self-test is successful, the UPS system startup is complete. Allow the batteries to charge for 12 hours in order to ensure that connected
equipment will continue to operate without interruption during a power failure. Once the UPS system is in use, it will charge the batteries
and maintain the charge level automatically.
