9-14 Frame 12 Installation
Power Wiring Input Power Wiring
Frame 12 drives utilize two parallel power structures, and therefore have
two sets of AC input power terminals. You must supply power to both sets
of input terminals. There are several methods for accomplishing this.
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.
