Argh! i totaly missed your photo from instructables about desat connection!
Now i will have to dissassemble everything up to PCB. Can you tell me if i can just connect all high transistors to common + rail? I would go from one IGBT to another and finally out to + rail with single wire. It would made for much cleaner installation.
Lower IGBTs will be connected to E like on your picture.

EDIT: I soldered a desat sense wire along lower PCB side. Black for lower transistors to E and red for higher transistors to + rail. The latter i just connected to one another and finally i put one wire out to + rail. When i connected PCB +12V system worked, no desat warning...
I will get my 40Vdc and put them on!
