WIRING OK indicator LED is not illuminated
APC Technical Support
If a problem cannot be resolved contact APC Technical Support.
Telephone: 1-888-88APCAV, or visit: www.apcav.com
Probable Cause: There are three reasons why this LED would
not be illuminated:
1. Reversed polarity exists at the wall outlet.
2. Neutral wire is overloaded.
3. Earth ground is missing at the wall outlet.
Solution: Operating the unit under these conditions may
affect its surge protection performance. Contact
an electrician to inspect the building or your
home wiring to fix the problem.
Probable Cause: Unit is on, but the LEDs are turned off.
Solution: Push the Power button, push the Select button
twice (this turns the unit off and back on again).
The LEDs should illuminate.
