Two primarys binded together is 230v, you'll use I assume 1 one of them for your location, blue is pos, brown is neg/neutral and gry is ground. These hook up to your IEC connector. Two secondary windings two 30v each with it's own ground/neg but you know where that goes on the s22 board.
So violet will be unused? Blue will be connected to L, brown to N, and Grey to ground. Red, yellow to ~ and black and orange to G. am I understanding you correct?
