Frame 14 Installation 11-21
Output Power Wiring for Frame 14 Drives
Frame 14 drives utilize two parallel power structures, and therefore have
two sets of output power terminals. You must connect the motor to both sets
of output power terminals.
Important: Parallel wiring must have the same cable dimensions, type and
routing. Non-symmetrical wiring may cause unequal loading
between the converters and reduce the drive’s ability to deliver
current to the motor.
Important: The minimum cable length for parallel motor cables from the
drive to the point where the cables connect is 5m (16.4 ft.). Join
the parallel cables at the motor end (not the drive end). Or,
install a reactor on the output of each power module with a
minimum of 5 µH prior to joining the parallel cables at the
motor end.
