Powerware 9120 6000i 6kVA ups indicates a charger failure. Can you give us a solution, this is the first time that the unit failed and we're not sure of the charger circuit location (we do not have a digram). thanks

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 in powerware 9 series 9120 6000i ,the fan is of a quality that it fails and the heat sink does not get sufficient cooling ,it runs on 12 volt ,i replaced it with a cpu fan from a mainboard on a pc and it works perfectly now. make sure that the fan is running else the charger might go in protection or can fail due to the transistor on heat sink fails.
Maybe you have many overvoltage situations at your area, that the UPS can't handle. It's a good idea to put before the ups an overvoltage protection or a stabilizer. Ask the manufacture for the overvoltage protection of the ups that can handle.
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.
