Powerware Answered Questions & Fixed Issues

Need to configure upon initial startup

it depends on which model 9120 700VA-6000VA. Also depends when is giving this message, in which stage of power on. give more details.

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 charger board has failure. Model already obsolete. Propose to buy a new unit

Sounds like it is not regulating the voltage and current charging the batteries. Consult a service manual to look for a repair method.

0377 is the default password. You can visit the Eaton website and visit the 9170+ UPS product page. To view the manual, click on the documentation tab.

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.

Check the manual - https://powerquality.eaton.com/products-services/legacy/9120-info.asp?act=smtc&id=&key=&Quest_user_id=&leadg_Q_QRequired=&site=&menu=&cx=3&x=8&y=6

It either means the ground wire in extension cord is not there or is open. It could also mean that the outlet wasn't wired with a ground back to the panel.

can blow diodes in the alternator and ECM

This happens a lot. Your input power lines fluctuate a lot from time to time. You get lags and sags and spikes on the power line. The UPS is just telling you this. Nothing you can do about that. Your UPS is operating normally. You don't really want to put the UPS into bypass during one of these fluctuations do you?

Battery breaker open or blown DC Fuse

Have the UPS perform a self test. Pres and hold the on button or the test button.

What are the alarms?

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.
