BK650EI Capacitors replacement ID
Hi everyone, I had an old (but seems still great, despite some light buzz-noise from the inverter... is that okay?) BK650EI model APC UPS. I need to replace some components, in details some ceramic capacitor of the tiny network surge protection board (two yellow and one blue)... i can't read the ID on them unfortunately.
Anyone have some suggestions? The UPS seems works also without grounding it (plugged into the mainboard), but I wanna to fix that even I know this is an old model.
I can't find any electric schematic about this model 😞
Many thanks for the support to anyone that can help me!
