Did u check the fuse inside the ups?
did the ups gave the error right after u replace the batteries? or some time after.
sometimes gives the message some time after and its because the charger isn´t working properly. the charger is a spare board in the 9120, 5 and 6 KVa.
good luck

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.

Powerware 9120 batt disconnected


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!

Hello, we have a Powerware 9120 and our question is: If you set the BYPASS option, can the batteries load?? Thank you


Not sure what you mean by load the batteries. Replace them? Yes. Bypass mode is typically used when servicing the unit. You can email Eaton if you like: SinglePhaseTS@eaton.com

I have a powerware 9120 (6kva) and about 1 week i replaced all 20 batteries after the UPS failed. but its displaying battery disconnected when i try to power it. i cant seem to figure the problem. i tried...


Did your UPS display "Battery disconnected" or did it display "Battery Failure"? If it was "Battery Failure", for some reason the Powerware 9120 will take almost 18 hours after plugging in to power after battery replacement to correct the Battery Failure indication. Charger has to charge up the batteries, followed by an automatic battery test by the UPS. If the indication was "Battery Disconnected", you will need to check the internal fuses to see if they are blown. If the UPS keeps blowing fuses, it will require a board repair.

The UPS dont go to on batteri


Say that question again. When poer is disconnected, the UPS dies???? The battery may be dead. Ensure that the battery is connected. If it is, the battery needs to be replaced.

Replace the batteries with new one then power the UPS without load for three hours or more so that the batteries can be charged. Then disconnect or switch off power to the UPS and observe if it will till be on using the batteries. If it will be ON then your problem is solved but if it goes off then your UPS is on BYPASS

Hi,

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

yes..and that happens after a period of time. When you get new ones, check the instructions on the initial charge/discharge requirements, and use those methods. tends to help with the battery life extension.
