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,

After you replaced the batteries did you perform a manual battery test?

If not do so.

SOURCE: my ups has is faulty i need a circuit diagram to fix it

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.

SOURCE: Battery Packs for Powerware 9355 UPS

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.

Message comes up on restarting reads configuration error. What is the cause and possible solution?


There is alot of possibilities on this on. Most likely it is in your input or output. You may have a 208V or a 480V input but your UPS may be programed for 240 or another voltage. I have the manual and all the knowledge you need. Email me at ericpettingill@hotmail.com

I had an alarm on 9390 which read : "Battery Test Fail". What would possibly cause it and how would I best prevent it from reoccuring.


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.

I WOULD LIKE TO BUY A NEWPowerware 9330-40kva UPS UNIT, COPLETE WITH BATTERIES .how much would that cost?


It's unlikely that you will be able to get a new one. The 9330 was discontinued many years ago though Eaton continues to service these models and provide replacement parts/batteries. I suggest that you call 800-356-5794 to see if Eaton has a partner that has any complete systems still in stock or in service inventory. The new UPS units are the 9355 and the 9390: www.eaton.com/9355 and www.eaton.com/9390 These new units are more compact, are more energy efficient and incorporate more advanced technology for monitoring and communication.
