When the grounded conductor is also present it is required as well to be identified typically with orange markings of some sort.No different that connecting a motor to any other 3 phase supply. Does not matter where the high leg goes on the motor. Just like any other, if the rotation is wrong just swap any 2 leads. It should be mentioned that your high leg should be in the middle position in panels breakers, starters, etc..
Run a feeder or branch circuit to supply a three phase load with no neutral at all - doesn't matter where the high leg lands or if you even identify it as the high leg.
