Are the fan working?
u may need to clean the ups, u will need to unplug it and open the front part by pressing on the boton sides and pulling out. take the bateries out. and now u can take out the screws in the back and clean the ups inside, just use a compressor, take care that doesn't have water inside the compressor, and u can replace the batteries, theya are conected in serie.
good luck

When i power on the ups it show site fault on the display,i checked the earth wire is ok . what can it be a problem?


Hi, here is the documentation page for the 9120 where you can find the manual: http://powerquality.eaton.com/Products-services/legacy/9120-info.asp You can also contact customer support 800 356 5737 or SinglePhaseTS@eaton.com. You may recognize the product as the Powerware 9120 but Powerware was bought by Eaton a few years ago. The customer support team is most ex Powerware and are familiar with the 9120.

My ups has is faulty i need a circuit diagram to fix it


I had a DC bus fault error displayed.

So I unplugged battery, then turned on UPS. It said Batt disconnected of course.

So when I plugged in the batt while the UPS was on, and held the power button for a few sec, the UPS displayed Batt testing.

After a few moments it was back online and had no faults!

Worth a shot.

Dear sir I have Powerware 9120 UPS since Jan-2007 to till now but yesterday it was getting problem and LCD show SITE FAULT Error what is meaning of that and why it occor and what is sholution. now it is...


If UPS is displaying "Site Fault", it is doing its job correctly. You need to check the wall receptacle. Probably hot and neutral reversed, or the neutral and ground are reversed, by whom ever installed the wall receptacle. You need to have the plug-in for the UPS intact, i.e. the ground pin must not have been cut off. If an extension cord connects the UPS to the wall, thge cord must be working correctly.
