What is the Wiring-Fault Indicator?
The LED indicator will illuminate red to warn the user that a wiring problem exists, such as bad ground, missing ground or reversed wiring.
What is bad ground?
If your CyberPower unit shorts out or there is a surge/spike in power, it can become a fire hazard by not properly grounding the wire to the earth ground that is connected to your house.
What is missing ground?
A missing ground can cause electrical shock.
What is reversed wiring?
This is caused by the hot and neutral wires being reversed in the wall outlet.
Solutions to try and diagnose the problem:
Try connecting the CyberPower unit into another outlet. If the wiring-fault light indicator is still illuminated contact an electrician to correct the problem with the faulty wall outlet.
Note: some of the products in their series lines will not come equipped with the wiring-fault indicator light
