B-2
Possible 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. The unit can still be “cold-started” using battery power, by
pressing and holding the power switch until the unit beeps.
Possible Cause:
Circuit Breaker has tripped.
Solution:
Check both home and unit circuit breakers. If the circuit breaker located on
the rear of the APC unit has tripped, the center post will be extended outwards about
1/4 to 1/2 inch. Push it back in to reset it. If the trip occurs again, reduce the amount
of equipment that is plugged into the unit and try again. While the unit circuit
breaker is rated for 15 Amps, the National Electric Code (NEC) dictates that any
particular home circuit should not be loaded to more than 80% of its rating.
Connected equipment reboots or turns off during or after the unit switches to battery power.
Possible Cause:
Battery was disconnected after unit had been installed and powered
on.
Solution:
The unit will warn users through the front display if the battery is
disconnected, but this warning could go unnoticed. Remove the front bezel by
grasping the sides and pulling straight back. Check the battery connection to make
sure that it is firmly pushed into its battery connector socket.
Possible Cause:
Unit is overloaded.
Solution:
If the unit has too much equipment plugged into the outlets, the runtime on
battery will become very short. Using the front display, you can see how much of the
UPS load capacity is used. Additionally, there is an “Overload” LED on the front
panel which will light ‘red’ if the unit is overloaded. If the unit is near overload or
overloaded (>95%), it is recommended the load be reduced by unplugging one or
more components.
Possible Cause:
Battery charge level was low at the time the unit switched to battery
power.
Solution:
Allow the unit to fully recharge, by leaving the unit plugged in. It takes
approximately 8 hours to recharge a discharged battery to 90% capacity.
