Back-UPS 1250

[Anonymous user]

I pressed the Display button (not the power button!) on my Back-UPS 1250 and immediately all my equipment shut off and an audible flatline beep started on the unit with an error message of F07!

I looked up the error as a temperature warning.

I unplugged everything and placed the unit in a cooler room on a tile floor to help dissipate the heat for about 3 hours.

The unit was cool to the touch.

When I plug it back in, it flashes the Online plug indicator a few times, then goes right back to F07 and the flatline beep.

Nothing is plugged into the unit, the unit is about a week old.

JMan,

Sounds like the UPS may have developed an internal fault. Have you tried reseating the batteries? Try coldstarting the UPS. Turn it off, unplug it from the wall, press and hold the POWER button until you hear a second beep, and then release. THis will boot the UPS up from its internal battery power. It will indicate that it's on battery and beep 4 times, every 30 seconds.

If you get this far, supply power to the UPS and it should go back online. Please let us know if the fault comes back.
