Each Liebert PSS has a visual SURGE PROTECTION 
indicator that illuminates (green) to show that the surge 
suppressor is functioning properly.
The Liebert PSS also has an audible alarm to alert you if 
the suppression fails. Surge suppressors are often hidden 
from view behind furniture and other objects that prevent you 
from seeing the visual indicator.

If wall mounting is desired, two keyed slots are provided and 
located on the back of the surge suppressor.

If the Liebert PSS malfunctions during operation, check the following chart for proper adjustment. For further assistance, 
please contact your local Emerson Network Power representative.

 

Try plugging the Liebert PSS into a different wall receptacle. 
• If the indicator illuminates, the Liebert PSS is operating properly and the first wall receptacle needs repair. Please 

contact an electrician to repair the faulty receptacle.

• If the indicator does NOT illuminate in a different receptacle:

• Your building wiring might not contain a ground conductor. In this case, the indicator light will not illuminate but 

you will still have power out of the Liebert PSS.

• The Liebert PSS may have been damaged. Please contact your supplier for any warranty return/repair 

instructions.
