Powerware 9120 6000i model indicates a charger failure. It is the first time that we opened this unit and we do not know the location of the charger circuit (we do not have a schematic diag). Could you give as a diagram or a solution to this problem. Thanks and more power.

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.

Powerware ups 6kv indicates Bat disconnected


1st does this have external battery modules or is it only the Internal batteries on this unit? You can disconnect the EBM's and the unit doesn't alarm even removing the internals with EBM;s attached won't cause an alarm. But it you only have internal batteries, open the front cover by pressing in the sides on the bottom left and right and pull it out and up at the same time revealing a black cable with a small anderson connector, make sure it is connected. you can pull the batteries out to check them to be sure they are properly seated. By the way the UPS in the picture only went to 3000va so is the 6Kv a different model?

Alarm #191 open cell voltage powerware 9130


Alarm error #191 comes from a battery test, where batteries are put under load for 25 seconds. (If the alarm is unexpected, you might have enabled the periodic 30-day battery test.)

#191 is test failure for battery internal resistance. So, need to locate and replace the bad battery, then run the battery test manually. If batteries are good, make sure no battery connector is corroded or loose.

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.

Is the fuse in a powerware 9135 user replaceble


There are numerous fuses (rectifier, inverter, charger, battery) on the 9135 that are located internal to the unit and not readily accessible to the user. Generally a blown fuse is accompanied by another component failure which caused the fuse to blow in the first place. As a result, additional troubleshooting and testing is usually required to identify the root cause of the failure. This of course leads to soliciting the services of a technician who has access to the schematics, test equipment, and parts to initiate a repair. Without the schematics, it's like working in the dark. For complete support, please contact Eaton (Eaton bought Powerware so now it's the Eaton 9135):

Hi,
