Powerware 9120 site fault error message - Powerware 9120 UPS System

A Powerware 9120 2000 is an uninterruptible power supply (UPS) device that provides power backup to connected devices in case of power outages or other power issues. If the UPS is shutting down at 50% charge and showing low power alarm, there could be several possible causes:

1. The battery is failing: The UPS is designed to shut down when the battery charge reaches a certain level to prevent damage to the battery. If the battery is failing, it may not be holding a charge and may need to be replaced.
2. The battery is not compatible: Make sure that the battery you are using is compatible with the Powerware 9120 2000 UPS. Using an incompatible battery can cause the UPS to shut down or display error messages.
3. The battery cable is loose: Check the battery cable connections to ensure that they are tight and secure. A loose battery cable can cause the UPS to shut down or display error messages.
4. The UPS is overheating: Check the UPS for any signs of overheating, such as a hot feeling on the top of the unit or a burning smell. An overheating UPS can cause the UPS to shut down or display error messages.
5. The UPS firmware is outdated or corrupted: Check to ensure that the UPS firmware is up to date and not corrupted. Outdated or corrupted firmware can cause the UPS to shut down or display error messages.

If none of these solutions solve the problem, it's recommended to contact the manufacturer or a professional technician for further assistance. They will have the knowledge and expertise to troubleshoot and diagnose the issue with your Powerware 9120 2000 UPS.

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 [email protected]. 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.

If UPS is displaying "Site Fault", it is doing its job correctly. Yoiu need to check the wall receptacle. Probably hot and neutral reversed by whom ever installed the wall receptacle.

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.

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.

Hi,

After you replaced the batteries did you perform a manual battery test?

If not do so.
