Wiring OK Status Indicator
When lit, the receptacle the C5 is plugged into is properly
wired. If not lit, one of three wiring problems exists in the
building wiring circuit: missing ground, overloaded neutral,
or reversed polarity. An electrician should be consulted to
resolve the problem.
Protection On Status Indicator
When lit, the C5 is functioning properly. If the light is
extinguished, the C5 has been hit by a surge and the
protection circuitry may be damaged.
Filtering Status Indicator
When lit, notifies the user that the EMI/RFI noise reduction
circuit is active.
Overload Status Indicator
If illuminated, this LED indicates the C5 is overloaded.
Unplug components until the light is extinguished.

Controls power to all 10 outlets. APC recommends the C5 be
left ‘on’ at all times. When illiminated, power is "on" at all
outlets.
