20 Most Recent Powerware 9120 UPS System Questions & Answers

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

hi see some of these answers it may help http://www.fixya.com/support/t24235663-powerware_9120

there is a 100uf/63v capacitor near the IRF630 fet. You need to replace this in order to fix this error. Along there is also a 2200uf/16v capacitor. It is a good idea to change the both at the same time.

Honestly, the cost of repair might exceed the cost of a new unit. We can likely get any parts needed to repair the unit, but might not be the most cost effective solution. Might want to price around for a replacement unit. If you need additional assitance, please contact us.
