Hello kingfisher1

You can find the owner's manual for the Minuteman Pro 520 UPS HERE.

You can find support for Minuteman UPS' HERE.

Refer to page (4) of the owner's manual for a description of the UPS' front panel controls and indicators.

Looks like if the 4th LED from the right is on, you need to replace your battery.

Left to Right the LED's are:
(1) Online; Boost; or On Battery (depending upon the symbol that is illuminated)
(2) Fault
(3) Overload
(4) Replace Battery

Please, let us know if you have any more questions, observations, comments, etc. on this topic. We are happy to help.

Thank you
BJ @:)

APC SURT3000XL UPS


The fault indicator means that there is a fault in the circuitry of the UPS. It could be the control board or another part of the system. (If the batteries were bad, you would see the Replace Battery light illuminate.) If the SURT3000XL is under warranty, contact APC. The standard warranty period is 2 years for repair/replacement. Note: you'll probably have to pay for the shipping of the unit. If the unit is out of warranty, replace it with a new UPS.

I hope this helps.

No indicator lights after replacing battery


I have one question, have you connect the battery terminal correctly the first time you install your new batteries? If not, it might be your battery fuse is blown during the process :) check your UPS battery fuse.

Have brand new APC 900 UPS and when plugged in, both green & yellow indicator lights flash. Non-stop. Left unit plugged in for 18 hours (off) to charge battery as info sheet suggested, but lights still...


Nope! The internal battery is not plugged-in correctly. Unplug the APC unit and open the access door to the battery (it is not dangerous to do).
Re-seat the two wire clips (red & black) to the battery. The positive post has a red mark on it.
Close it up and charge for a few hours before using.

If the symptoms continue, return unit to store.
