3. Operation
LED Indicators
- Protected LED (Green): When illuminated, this LED indicates that the surge protection is active and your connected equipment is protected. If this light is off, the surge protector may have absorbed a surge and needs to be replaced.
- Grounded LED (Red/Orange, if present): This LED indicates that the wall outlet is properly grounded. If this light is off or red/orange, the outlet may not be properly grounded, and you should consult a qualified electrician.
