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.
For applications that require that the DC– and DC+ terminals for PowerFlex
700S or 700H frame 12 drives be connected in common (for example, 12 pulse
applications, or when using a dynamic brake), you must purchase and install the
frame 12 DC Bus Connector kit, which is sold separately from the drive. See the
PowerFlex 700S and 700H Frame 12 DC Bus Connector Kit, Installation
Instructions, publication
PFLEX-IN022 .

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.
