As I mentioned, I have a note to the right of PSU’s which says the commons (Negative) of each PSU is connected to the earthed star ground. Is this not enough?
Not the proper way of showing this but to avoid confusion with too many lines I decided to have the note instead
Al please let me know if the above it’s ok. I will revise the schematic to include the diodes change and if need to I can also revise the grounding
