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.
If the this problem remains unsolved, contact APC Technical Support
at 888-88APCAV or by visiting www.apcav.com.
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.
