400: Automatic transfer switches. Help!

[Mixman1]

I need help understanding the wiring of the factory installed automatic transfer switches in my 2011 Lagoon 400. I will attach pictures. I know the general function, but in my OCD need to understand everything on the boat, I went looking for a wiring diagram of the switches themselves. Schneider electric is the manufacturer but their website isn't helpful at all. If anyone can help, that would be great.
Also wondering about the long term reliability of these. Would an old school mechanical transfer switch be a better solution?
