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