I just moved my Powerware 9120 UPS from one location to another, and noticed the fans are running constantly. I don't recall if they did this at the first location. Should I be concerned? Unit wasn't dropped, tipped, or damaged in any way. I don't have the software to se if there is a setting that needs to be adjusted via a soft pot. Any suggestions?

Re: fan is running constantly
In the 9120 series the fan is allways working, but as 2 speeds. the higher goes of when the load goes around 80% or the temperature inside is higher. just make sure the the fans are clean, and check the ups temperature.
but is normal.

hey dude your problem is so simple..below are my solutions.
if you already secured the fans for the replacement then its easy for you to do it, try to totally shut down your UPS removing the input and battery supply. avoid replacing the fans with power, its to dangerous. it consist of almost 400VDC inside in it.

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.
The cooling fan is probably not working. Unit will overheat. Check the fan to see if it run continuously with no scraping noise with the UPS turned "ON". If the fan does not run, open the case and replace the fan.
You're absolutely right, overtemp on batteries can greatly escalate the failure of batteries, particularly older or heavily loaded ones. The fans are a fairly easy replace, if we can assist in any way, please do not hesistate to contact us.
