FAQ - What to do when your Back UPS will not power on - common problems

This was originally posted on APC forums on 2/4/2009


Please follow the below troubleshooting steps if your UPS does not respond.

• Back-UPS not connected to an AC power source.
Check that the Back-UPS power plug is securely connected to the wall outlet

• Check the battery connection.
Per Department of Transportation regulations, we ship all of our UPS products with one battery lead disconnected. (See Battery Replacement section of the User's Manual, or refer to the large yellow sticker which should also inform you of how to connect the battery for further instructions.)

• Cold Start
Attempt to start the Back UPS product off it’s battery by cold starting it. There are 2 ways different ways to do this. First try to turn it on while it’s unplugged from the wall. If the LED(Light Emitting Diode) does not come on then Hold the on power button in until you here a long beep and let it got before the beep finishes (usually about 4 seconds). When the unit is started off its battery it will indicate it is using its battery to power the unit. If the UPS works on battery, plug it’s power cord into the wall and see if it works online.

• Utility input voltage is out off range
Check the wall outlet that supplies power to the Back-UPS using a table lamp. If the lamp bulb is very dim, consider adjusting the transfer voltage on the UPS

• Back-UPS circuit breaker “tripped”
Disconnect non-essential equipment from the Back-UPS. Reset the circuit breaker (located on the rear panel of the Back-UPS) by pushing the circuit breaker button fully inward until it catches. If the circuit breaker resets switch the Back-UPS on and reconnect the equipment one-at-a-time.

If the circuit breaker trips again, it is likely that one of the connected devices is causing the overload
