•
• LINE "OK" (Green Indicator Light) (all models except Power Center)
Indicates 120V AC power is present with no wiring faults detected. When this LED is illu-
minated,AC power is safe for connected equipment.
•
• LOW VOLTAGE (Yellow Indicator Light) (all models except Power Center and
Command Console Compact)
Indicates that incoming line voltage has fallen below acceptable levels. If this LED illuminates
while you are using your Under-Monitor Surge Suppressor, you should turn off your equipment
to prevent possible low-voltage brownout damage. When the line voltage reaches a safe
level once again, this light will turn OFF, indicating brownout danger is over.
NOTE!
If the Line Fault indicator light illuminates, carefully check the AC receptacle the Under-
Monitor Surge Suppressor is plugged into. The receptacle must be tight and securely
grounded. A loose AC receptacle may cause the Line Fault indicator light to illuminate.
It must be understood that this Red LED indicates the presence of a wiring fault, but
does not indicate the exact nature of the fault. Therefore, a qualified electrician should
be contacted to make necessary repairs.
NOTE!
If, after inspection by a qualified electrician, a wiring fault is not detected, the Line Fault
indicator light may be indicating that the surge-suppression components have been
compromised as a result of surge damage. Even if the surge suppressor is providing AC
power at all of the receptacles, it may not provide its total rated surge suppression as
outlined in the "Specifications" section. Should you require service, call Tripp Lite
Customer Support at (773) 869-1234. Explain fully the perceived problem to the cus-
tomer support person. They will either remedy the problem over the phone or give you
instructions about return, repair or exchange.
