AC Input Wiring
The table below identifies which frame 11 drives contain only one rectifying
module and which frame 11 drives contain two rectifying modules. Drives with
one rectifying module contain only one set of input power terminals. Drives with
two parallel rectifying modules contain two sets of input power terminals--you
must supply power to both sets of input terminals on these drives. There are
several methods for accomplishing this. Each of these methods is shown below.

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.
