I am confused enough with where to start on this project and when I look at the existing cabinet of electronics … I don’t know what to keep and what will get pulled. If I were to just start with a new a single phase power supply, then I don’t have to try and figure out the existing three phase power supply and what wires to use. I think it may also be easier to get help if I am using a power supply that I have some documentation for.
I do know that RickB, who has successfully made this retrofit on a Tree325, did use the existing three phase power supply. So, I believe his well made schematics may reflect that.
