Power Wiring 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.
