Figure 2. C3 Front Panel Controls and Indicators
Wiring OK Status Indicator
When lit, the receptacle the C3 is plugged into is properly wired.
If it is 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 C3 is functioning properly. If the light is off (not lit),
the C3 has been hit by a surge and the protection circuitry may be
damaged.
On/Off switch
Controls power to all the outlets. APC recommends that C3 be left
ON at all times. When illuminated, power is ON at all outlets.
