Help me!!! my eaton powerware 9120 6kva have a problem: low op/v (low output voltage). i have change all IGBTs . i nedd a circuit diagaram.

http://www.manualslib.com/manual/41745/Eaton-Powerware-9130.html?page=1 Your model has a 10 year prorated warranty. You might have to have it repaired that way.

From the user manual: http://lit.powerware.com/ll_download.asp?file=Eaton%20FERRUPS%20User%20Guide.pdf page 108.

The output voltage is below the alarm setting as determined by setup parameters 59 and 60.

Verify the output voltage using a voltage meter. If correct, verify setup parameters 59 and 60. If alarm condition continues, bypass the UPS and turn the UPS switch off. Call your service representative.

You have more devices/draw on your device than it is rated for - disconnect some of them.

need to change batteries.
cannot hold charge

This unit has been replaced by the 9130. It is possible that the original power cell is low in power or not charging to full capacity.

I don't know the exact cross reference number for you but Eaton tech support should be able to help you. Eaton bought Powerware 6 years ago but retained their service support personnel.

Maybe you have many overvoltage situations at your area, that the UPS can't handle. It's a good idea to put before the ups an overvoltage protection or a stabilizer. Ask the manufacture for the overvoltage protection of the ups that can handle.
