The unit will not turn on
The Overload LED is illuminated
The Wiring OK LED is not illuminated
There is no input power, or
insufficient input power from
the wall outlet.
Use a voltmeter to check the output of the wall outlet. Use a device that is known
to work properly to check the outlet.
Note: The unit will not turn on if the input utility power is out of the acceptable
range.
A circuit breaker has been
tripped.
• Check the building circuit breakers and the unit’s circuit breaker. If the circuit
breaker on the unit has been tripped, the center post will protrude from the unit.
To reset the breaker, push the center post into the unit. If it trips again, unplug one
of the components plugged into the unit and reset the breaker.
• G50NETB2 is rated for 15 Amps/G50NETB-20A2 is rated for 20 Amps,
however, the National Electric Code (NEC) dictates that any home circuit should
not be loaded to more than 80% of its rating.
Note: If the breaker is tripped again after trying this solution, contact APC
Technical Support.
Power is not supplied to some
outlets.
Power to the
CONTROLLED outlets has intentionally been turned off.
