PowerFlex 750-Series AC Drives
Recommended Motor Cable Spacing - Floor Mount Frames 8 and
Larger
Frame 8 and larger drives typically require multiple conductors in parallel. Wire
size and number of conductors must be determined by the customer based on
drive rated current, local codes, operating conditions, and specific application
needs. When using multiple conductors per phase, symmetrical spacing of the
input and output power cabling over the span of the bus bar for each phase is
recommended.
When using multiple conductors per phase, wires must be arranged so that each
conduit, bundle, or cable contains equal numbers of conductors from all three
phases.
