A UPS shutdown is initiated by the LOAD OFF command on the UPS Control screen. The UPS LOAD OFF
controls the UPS output by powering down the UPS and de-energizing the critical load.

An action confirmation screen is displayed. Follow the on screen prompts to shut down the UPS or to
cancel the shutdown. Selecting YES will immediately shut down the UPS and de-energize the critical load.

cleared.

WARNING
Emergency Power Off (EPO) and Remote Emergency Power Off (REPO) functionality is disabled for UPS
systems configured for UL 924 auxiliary lighting. To remove power from the system a LOAD OFF command
(see paragraph 7.3.15 Using the UPS LOAD OFF Command) must be given using the front panel controls and
all breakers opened.
A UPS emergency power-off is initiated by the REPO pushbutton switch. In an emergency, you can use this
switch to control the UPS output. The REPO switch de-energizes the critical load and powers down the UPS
immediately, without asking for verification.
The UPS, including Bypass, remains off until restarted.
