You can check the battery fuse or the charging fuse. If it's more then that it's going to be a very costly fix.

This error can only be cleared by the Eaton technician with their laptops. If this is a new unit it HAS to be factory started or your warranty will be void.

9390 Requires a UVR type battery breaker. Unfortunately a configuration error will require a service visit from a technician. The proprietary service software will have to be used to reset this.

Hi Ahmad,
I've got same issue on the same UPS generation last week we tried to solve the issue by changing some dead batteries but without success, it tripped a gain with same alarms.
I hope someone answers our question ASAP.

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.

Check the connections on the batteries. One or more may be loose or corroded. Also check the fuse for the batteries. It may have blown.

Hi Anonymous,
I want to help you with your question, but I need more information from you. Are the batteries new? If you did recently replace the batteries in the cartridge, did you check the connections and make sure contact as being made?

Let me know!
