Emerson Liebert PSA Line-Interactive UPS 500-1500VA User Manual

The UPS Control in the Contact Closure setup permits you to turn off the UPS output. This feature 

requires a special cable and is available only on certain UPS models. Contact Emerson Technical 

Support for information.

To open the UPS Control dialog box and turn off the UPS output:

• Click on the Overview tab.
• Right-click on the UPS device name to open a pop-up menu, then click on UPS Control. 

• To turn off power to the critical load, click on the Turn UPS Output Off button.

Turning the UPS output off is not recommended. All loads plugged into the UPS will lose 

power within two (2) minutes. This may require a manual shutdown of your computer 

network.
