I have a "low A/C output" message. Is this related to a faulty DVR or another board?


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.

Replacement batteries were installed but were not Powerware brand. The brand put in is DataSafe P/N of Powerware is PWHR12120W3FR and I need the cross reference to the DataSafe type.


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.

Hi we have problem with 6kva 9120 eaton ups,


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.
