Its a dual phase machine, just want to verify the circuit breaker wiring as I did not wire it.

I have the 50 amp plug wired normally, but have to way of knowing how the circuit breaker is actually supposed to be wired as there is no polarity diagram in the manual as far as I can see.

There are internal switchovers for single phase which I have already switched all over as per the manual.

There's no neutral connection on that machine. On your diagram there's 2 wires that go off to the right that connect to a transformer (T3) that supplies the control board with power - your L1 and L2 need to be connected to those 2 on the breaker

Well I think this is the correct way to wire it:

CR2 and CR1 wired with L1 and L2

I think I need to swap my red and white wires on the plug side of the circuit breaker. Which would make sense actually because originally the white wire was cut back in the old plug that was on it and it used red and black for L1 and L2 I guess.

I found this picture from another user.

Still not 100% though but I think I will be safe to try it. You are right though and I am stupid and forgot basic electricity for a minute... there is no neutral on this plug just two hot lines. Been a while since I did industrial wiring.

Correction: CR2 and CR3 I believe are line 1 and line 2
 
I can't tell what the last blurry photo is supposed to be showing, but from your photos at the beginning of the thread, the white and red wires have been swapped. Black should be across from black, red across from red, and white across from yellow.

The black and yellow are your CR1 and CR2, which should be your hot and neutral (black hot, white/yellow neutral, red unused).

You showed that the capacitor board buss bars have been set to 230V, but also make sure the other two (main transformer behind the front panel and auxiliary transformer next to the circuit breaker on the opposite side from the ground stud) are also set to 230V (buss bars beside each other like _ _, not in the middle like . _ .).
