Powerware use to use the default password "MEMORY" for a lot of their digital display UPS Systems. You could try that. Conversely, if you download the full manual off the Powerware site, the password is usually listed at the front of the manual.

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.

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.

Just restarted a 9339-40 ups after moving it to another bldg. And it has no output now. Screen says epo needs reset. Any help?


Most follow the reset procedures to reset from a EPO shutdown. Usually it is a fuse on Powerware that needs to be pushed back in.

Battery Packs for Powerware 9355 UPS


The Batts can be charged externally, then refitted, usually I extend the DC cables so I can work with the batt outside the unit. This is ONLY to be done if you understand the risk and what may happen if you get it wrong.

Batts are always live and can cause fire/explosion/severe burns if shorted!
IF YOU ARE NOT SURE THEN GET SOME EXPERIENCED HELP!

OK so the UPS will not normally recognise a very low batt pack, that is the reason you can not start the test, this test will back of the rectifier so the batt pack takes the load for a short period.

If the batt pack is out of range then this will make the load go off, so the UPS is designed not to allow the test,unless the batt is at the right level.

If you can get the batt pack up close to normal then the unit will recharge it to full.,Wait until it is fully charged before testing.
If this is sucessful the cyle the batt a few times allowing it to reach around low batt warning before recharging. This will assist the batt in recovery. During this process if possible monitor with a test intrument(fluke 123 or 43B will do) the batt pack discharge curve , once the batt pack has dropped to its charge level from float, it should be a smooth decay.
depending on the state of the batts you may be ok, if there are weak ones in the string then you may have to replace all of them depending on the age of the batt pack.

MAKE SURE YOU ARE VERY CAREFUL WITH BATTERIES, THEY ARE VERY DANGEROUS, AND ALWAYS LIVE!

Check you manual for safety procedures, BEFORE working on Batteries.


hope this helps

thanks for using Fixya
