Question about Powerware PW9150 12.5KVA/8.75KW (pf1221114ue0010) UPS System
If the load is dropped then there is a serious fault with the ups, even if the inverter fails, it should go to bypass and not drop the load.
Sound like a control fault, I suggest you need a ups tech.
This equipment has many dangerous parts inside. Batteries are always live and very dangerous. The boards are stuffed the surface mount components.
You need an approved service agent, who should be able to help
