20 Most Recent APC Smart-UPS 1000VA UPS System Questions & Answers

http://www.apcc.com/resource/include/techspec_index.cfm?base_sku=SU3000NET&tab=documentation Above is the link to your manual and troubleshooting guide. After that your on your own. These small units like this are throw away units if the battery replacement does not work. Thier cost is so low most times it is better to buy a new unit rather than new batteries.

You need to run recalibration on the unit.  The supplied PowerChute software & cable will allow you to do this if you hook the UPS up to a PC (I know it works with the serial cable, not sure about USB).  If you only have a MAC then I cannot offer a solution other than to buy the standalone PowerView device from APC.  It will cost a bit more than a battery, but may save you from buying needless batteries in the future.  I finally broke down an bought one, but note that I was still having the problem after the 1st recalibration.  By trial and error (and maybe a vague memory) I put my MAC in sleep mode, that dropped the load to stop the lights from flashing.  Then I recalibrated with a 22% load and now it finally seems better (lights no longer flashing).  This was with a Smart-UPS 1000.
Let me know if that helps.

chck all your bus controller and also check DC capacitors.

a relay is jammed?? fused shut or bad switching silicon replace the controller board instead get a new one too many things to resolve if your batteries burn out the inverter then its some timing issue not worth it to repair the board replace the whole control or new one!!! and reuse the cells {ebay}

THIS seems the be the answer to your question. Hope this helps

try to check if the battery itself is still working.

What is the Utility voltage at the wall. Is it higher than normal? Powerchute can be used to set the norminal voltage and higer and low voltage limits of the UPS.

Probably because polarity at the plug is reversed, check for that. There is a red LED at the back of the unit, if it is lit, polarity at the plug is reversed, you will have to correct this.

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.

how about relay out?

Ereadlu, What's the problem? And is the UPS a Smart-UPS or Symmetra? Jotting down the exact model number will help. Daniel • Power & Systems Innovations • 800.260.2259 • www.psihq.com ** If this helped - Give it a Thumbs Up :) **

It's cheaper to get a new one then to try to fix these. Taking into account time and frustration.

UPS in overload. Try removing some of the attached devices one at a time to determine which on is causing the overload... it may also be a combination of devices causing the overload.If you need UPS, Surge, or Power Related help contact Daniel @ Power & Systems Innovations 800.260.2259 or go to our website: http://psihq.com/

Hi Lalmuanawmah,Did you replace the batteries with new ones? What LED lights are on? It may still be a battery issue -- battery price is $65.95.Reply or call if you need more help with this -- 407.380.9200
