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.

After you replaced the batteries did you perform a manual battery test?
If not do so.

it could be your uPS given the problem the mosfet might be spoil... as the temperture is high because of the transformer is not given the clean current to bypass the systems and the there not much air filter out from the ups depend on the condition of the room might be too warm.. there a higher chance was the mainboard problem well u check the sensor lst and also try to unplug and plug bk to restart the sensor... if it will not slove the problem check with the vendor to come down and check..

I had a DC bus fault error displayed.
So I unplugged battery, then turned on UPS. It said Batt disconnected of course.
So when I plugged in the batt while the UPS was on, and held the power button for a few sec, the UPS displayed Batt testing.
After a few moments it was back online and had no faults!
Worth a shot.

If you battery packs are all at 130volts DC, then all of the packs will have become dead, and the batteries are not recoverable. Your battery DC bus voltage on a Powerware 9355 20 to 40kVA rated UPS is nominal 432 volts DC - 36 batteries in series in each string at 12 volts DC per battery. If batteries go below 10.5 volts DC each, or 378 volts DC bus voltage, no amount of charging will recover these batteries. You should not be recycling the DC battery breaker, unless you felt the battery breaker was faulty. The UPS would have given you an alarm message of either battery breaker Off, Charger Failure, or Low DC Bus Voltage long before the these batteries failed.
The battery test will not proceed if the batteries are dead.
