1600XP Series Installation and Operation Manual
11.2 Starting the UPS (Normal)
Turn the main circuit breaker (MCCB) on the back of the UPS (see Appendix A) to the ON position. The
breaker should remain in the ON position.
Verify that the On-Line LED on the front panel (see “12.1 Front Panel Layout” on page 22) lights
green. All LED’s on the front panel may light for a moment when the input breaker is turned on. This is
normal. The UPS will now be supplying power in the On-Line mode. If the On-Line LED is not illuminated
push and hold the RUN key for approximately 3 seconds.
NOTICE
When running the UPS for the rst time charge the batteries for at least 24
hours (input breaker on) before operating the connected load. Failure to do so
will result in reduced battery backup time.
11.3 Stopping the UPS
To stop the UPS press and hold the STOP key approximately 3 seconds until the On-Line LED changes
from green to off (audible beep). The UPS is now in the bypass mode.
NOTICE
If the input breaker is turned off while UPS is in the bypass mode, the output
power stops. Any load devices will lose power.
Ensure that all sensitive loads have been previously shut down.
To completely stop the UPS, turn the input breaker at the back of the UPS to the OFF position.
