I have a powerware 9120 (6kva) and about 1 week i replaced all 20 batteries after the UPS failed. but its displaying battery disconnected when i try to power it. i cant seem to figure the problem. i tried...


Did your UPS display "Battery disconnected" or did it display "Battery Failure"? If it was "Battery Failure", for some reason the Powerware 9120 will take almost 18 hours after plugging in to power after battery replacement to correct the Battery Failure indication. Charger has to charge up the batteries, followed by an automatic battery test by the UPS. If the indication was "Battery Disconnected", you will need to check the internal fuses to see if they are blown. If the UPS keeps blowing fuses, it will require a board repair.

The charger in powerware 9 series 9120 6000i ,the fan is of a quality that it fails and the heat sink does not get sufficient cooling ,it runs on 12 volt ,i replaced it with a cpu fan from a mainboard on a pc and it works perfectly now. make sure that the fan is running else the charger might go in protection or can fail due to the transistor on heat sink fails.

When i power on the ups it show site fault on the display,i checked the earth wire is ok . what can it be a problem?


Hi, here is the documentation page for the 9120 where you can find the manual: http://powerquality.eaton.com/Products-services/legacy/9120-info.asp You can also contact customer support 800 356 5737 or SinglePhaseTS@eaton.com. You may recognize the product as the Powerware 9120 but Powerware was bought by Eaton a few years ago. The customer support team is most ex Powerware and are familiar with the 9120.

Greetings!
How many years is your ups working? UPS is usually run by a battery, some of them are disposable and needs replacement. If it does not charge anymore it needs replacement of battery.
Thanks.

1st, the 9120 is a 700, 1000, 1500, 2000, 3000, 5000 or 6000 Va
if it is a 6000 Va that voltage sounds ok, and the ups as no problem, each battery will be around 12,75 Volts, it will be higher and the charging circle ends.

9120 Battery Failure


sounds like inverter is unhappy(causing the input fuse to blow. maybe, just maybe, this Powerware 9120 has given up the ghost? The inverter can short for a variety of reasons. Try to take out the battery completely, and run it as just a power conditioner. If that works, then you have an unhappy inverter in there.
