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.

Remove the front panel plastic cover where the batteries are located, then plug the two connectors together, restart the UPS, and it should be fine.

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.

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.

This error indicates that the battery packs are no longer able to supply the expected run time or load capacity that the UPS needs. The batteries will need to be replaced.

You will have to consult the user manual for the default password. Usually default passwords are admin/admin.

Remove all load.
Turn off UPS.
Start UPS.
If fail remains, check the fuses and battery.

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 will have very little benefit from a schedule.
All UPS are structured similarly.
A rectifier, an inverter.
A battery charger, a bypass ...
