The COC shouldn't be necessary if the installation is confined to the control panel which should be classed as part of the machine, not part of the building electrical installation.
I can see you going with parallel cables, the 400mmsq conductors I'm guessing this motor will require make for difficult installation with bending radius etc.
Is this a serious project or is it just for fun? If it's serious I'll dig out my college notes, ampacity and derating tables when I've got a spare hour.
