Using the UPS LOAD OFF command
A UPS Load Off is initiated when the Load Off command is selected in

The UPS (including bypass) remains off until restarted.
To use the LOAD OFF command:
1.
Select the CONTROLS symbol in the main menu bar.
The System Control screen is displayed.

Select UPS in the System Control screen.
3.
In the UPS System Control screen, select the NORMAL

→
LOAD OFF command, depending on the UPS
mode, and press the
push button.
The Verify Action screen is displayed, providing you a choice to
proceed or abort the shutdown.
CAUTION
When LOAD OFF is selected in the following step, all power to the
critical load is lost. Only use this feature when you want to de-energize
the critical load.
4.
Select Yes or No and press the
push button.
Selecting Yes immediately shuts down the UPS and de-energizes
the critical load. Selecting No aborts the shutdown.
CAUTION
Do not attempt to restart the system after Load Off until the cause of
the shutdown has been identified and cleared.
To restart the UPS after the LOAD OFF, follow the procedure in Section
7.3.1 or 7.3.1.

Power is present inside the UPS cabinet after the upstream input
feeder circuit breakers are opened because of the installed external
