Recommended Installation of Motor Cables

4.4
If the power units are connected in parallel without output filters or only with a common-mode filter, the recommended common
coupling point of motor cables is at the motor terminals. It is also possible to use an alternative installation method where the common
coupling point of the motor cables is near the drives. In this case, to avoid current imbalance, the installation must be symmetrical and
the tolerance of cable length (impedance) to common coupling point is maximum 5%. If the cable connections are not symmetrical, use
a dU/dt filter or a sine-wave filter.
