PowerFlex 700S and 700H Frames 10...14 IP00, NEMA/UL Open Power Structures
Output Power Wiring Frame 12 and 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.
Figure 36 - Frame 12 and 14 Output Power Wiring Example
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. Refer to
Figure 36
below for details.
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. Refer to
Figure 36 below for details.
