Product Line:

APC AV H-Type power Conditioner 

Environment: 

H10, H15, H10BLK & H15BLK

This document will assist you with basic troubleshooting steps.

Resolution:
 
Problem and Possible Cause Solution
 
Problem: Unit will not turn on.
Input power cord is not connected properly Ensure supplied power cord is connected firmly at both ends.
No power or insufficient power available at the wall outlet. 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.
Circuit Breaker has tripped. Check both home and unit circuit breakers. If the circuit breaker located on the rear of the H10 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.
 
Problem: The overload LED is lit.
Unit was overloaded. There is an “Overload” LED on the front display panel which will light ‘red’ if the unit is overloaded. If the unit is overloaded or nearly overloaded (>95%), it is recommended that the load be reduced by unplugging one or more components.
 
Problem: “Wiring OK Indicator” LED is not illuminated.
There are 3 reasons why this LED would not be illuminated:
1. Reversed polarity exists at the wall outlet.
2. Neutral wire is overloaded.
3. Earth ground is missing at the wall outlet.
Operating the unit under such conditions may impact its surge protection performance. Contact an electrician to have them inspect the building or home wiring to fix the problem.
Unit is on but LEDs are turned off. Push the Setup button, push the Select button two or three times. The LEDs should illuminate. Choose the dimmer setting (see the sections on “Front and Rear Panels” and “Setup the H10” in User Manual).
 
Problem: The Line Boost and Line Trim LEDs are flashing.
One of the inner relays is welded Remove the input cord and then plug it in again. If the problem remains, contact APC.
