1. Switch the main circuit breaker (MCCB) on the inside front of the UPS to the
ON
position.

mode.
NOTICE
When running the UPS for the first time or after the power failure backup operation, charge
the battery cabinet batteries, if any, for at least 24 hours (input breaker on) before operating

On-Line
LED changes
from green to off. The UPS is now in Bypass mode.

Ensure that all sensitive loads have been previously shut down.
To completely stop the UPS, open the input breaker MCCB, the secondary Input breaker (if available), and the External
Battery Cabinet breaker (if available).
