Frame 12 Size Drives
400 and 480 Volt AC Input Wiring for Frame 12 Drives
Frame 12 size 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. 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.
