Well i am almost there and luckily i remembered...

When i couldnt install PCB one way, due to current sensors, i rotated it so i now have IGBT contacts facing backwards. Eg. G1 E1 on IGBT is now G2 E2 on PCB and vice versa. Please advise Paul. Would that cause harm to IGBTs? Or is the switching so symetrical nothing would happen.
First picture is with contacts connected. On the second i tried to criss cross them so they would plug in ok. Which would be better?

Also is the wire length important? I made twisted wire, but with crossed cables wire length is more than i planned. at least for comfortable installation. Would wire length be an issue? Should i add one TVS diode directly to IGBT GE contacts? Wire length is now 10cm from PCB to GE.
