4.3 - Special cabling
In a situation where several inverter modules are used in parallel to power a single high-power motor, if no balancing reactor is
added to balance currents, parallelisation shall be carried out in the motor’s terminal box. It is imperative that the cables of each
U/V/W phase of the motor be distributed symmetrically on the ranges of the U/V/W connections of the inverter modules.
