Frame 14 Mechanical Installation
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 5 m (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.
