Using the LOAD OFF Button

Load Off is initiated by the covered, red LOAD OFF button on the Monitor Panel. This button is protected by a clear plastic shield to prevent accidental activation. In an emergency, you can press this button to instantaneously open the input breaker and interrupt UPS output. The UPS is cut off from utility power, and the critical load is de-energized. All power to the critical load is lost. The UPS (including Bypass) remains locked off until you reset the LOAD OFF button.

All power to the critical load is lost when you press this button. You should use this feature only in an emergency or when you want to de-energize the critical load.

To restart the UPS after pressing the LOAD OFF button, follow the procedure “Resetting the UPS System after Load Off” on page 11-2 before starting the UPS.

NOTE The Remote Emergency Load Off option functions the same way as the LOAD OFF button on the Monitor Panel.
