Troubleshooting
This section describes possible causes and solutions for the following problems:
•Unit will not turn on.
•“Wiring OK Indicator” LED is not illuminated.
Unit will not turn on.
Probable Cause: Input power cord is not connected properly.
Solution: Ensure supplied power cord is connected firmly to the wall outlet.
Probable Cause: No power or insufficient power available at the wall outlet.
Solution: Ensure the wall outlet has good power by using a voltmeter, or by plugging in another device.
Note: The unit will not turn on and accept incoming utility power if the power is out of range.
Probable Cause: Circuit Breaker has tripped.
Solution: Check both home and unit circuit breakers. If the circuit breaker located on the side of the C5 has tripped, the center post will be extended outwards about a quarter to half inch. Push it back in to reset it. If the trip occurs again, reduce the amount of equipment plugged into the unit and try again. While the unit’s breaker is rated for 15 Amps, National Electric Code (NEC) dictates that any particular home circuit should not be loaded more than 80% of its rating.

Probable Cause: Unit is overloaded.
Solution: The load bar top panel of the C5. If the display indicates over 100% (LED lights in red), or close 100% (LED lights in yellow), the unit may be overloaded. If the unit is overloaded or nearly overloaded (>95%), it is recommended that the load be reduced by unplugging one or more components.
