yeppers...those APC units sometimes kick the monitoring software. sometimes you need to unhook the connection cables(like a reset) so that the firmware can 'unlock' which can cause that christmas tree effect on the panel lights.

SOURCE: APC Smart UPS 1500 will not start.

It could be that the cable to the front-panel got damaged during the battery replacement.  After all these years you would think APC would improve that aspect of their design.  All I can suggest is inspecting the cable and where it connects to the front panel.

SOURCE: Overload light in APC RS 800 UPS

it seems that the inverter circuit of your UPS is dying. the solution here is you have to open up the UPS and check the inverter circuit. to make easier, check the power mosfet if its leaking.

SOURCE: APC SMARTUPS 1500VA Battery Problem When Replaced

You are correct. The APC Smart line has a partial charge when it's new. Similar to cordless phones, the work right away, but you're still supposed to charge them before use for best results.

Just leave it plugged in with no load for a couple hours and it will be fine.

Apc xs800 new batteries


I Bought two RBC32's and had to hook them up to the connector and did it wrong on the first try. Make sure you connect the yellow to the Red terminal on one battery and the Black on the other, then connet the remaining red to red on one and black to black to the other. Once I did that and plugged it back in everything worked fine.

We have a APC Smart UPS 2200XL. We had a power failure last night and now all six lights in the front (AVR Trim, On Line, AVR boost, Overload, On Battery, and replace battery) are flashing at the same...


Hello,

The light pattern indicates the batteries need to be replaced. The typical life of UPS batteries is 2.5 years, after this time the cells will not hold the proper charge. When your power when off last night the UPS would have tried to switch to battery power but it most likely failed after just a few minutes as the batteries shorted. The UPS has a protection circuit that prevents it from starting up properly with dead batteries so you get the flashing lights and the unit shuts off. The batteries are available in most cities from car battery dealers, not like Wal-mart but battery only dealers, just look in the yellow pages for batteries. You can take the old batteries out of the unit by removing the front panel and unscrewing the metal plate just behind the front cover. The old batteries are connected with a wiring harness that plugs in. Just bring the old batteries to the dealer so they can get you the correct replacement part. The new ones should be less than $100 so it is well worth the price compared to a new unit.

I hope this helps, if so please rate our solution.

1 Answer

The 'ON BATTERY' light goes on every so often and the unit beeps. Very annoying as this is not an overload so I want it silent.


Hello.

There might be several reasons for this:

1) Malfunction of your UPS' circuit
2) Damaged wire cord
3) The power on your wall socket fails too often
4) Most likely the batteries are exhausted. See the UPS' manual about batteries replacement.

Good luck

My apc keeps clicking and the on line and on battery lights keep blinking


Often, it is an expired battery that will cause an issue like this. Since a bad battery renders the APC ups useless, it will usually display blinking lights to let you know that something is wrong. The software, if installed, will also help troubleshoot the problem. You find which battery you need from this site: http://batteryinternational.com/ups-batteries-apc-batteries.html

APC back-ups XS 800 battery backup : warning


Turn it off and unplug it from the wall.
Open it up and make sure that the red and black wires are connected.
If they are the battery needs to be replaced. They are only good for 2-3 years. If you are not comfortable with my instructions, call APC for free support. (800) 555-2725
