Diagram of PCB, cable, and wire connections (if applicable)

Refer to the figures for an overview of the VDC3 Printed Circuit Board (PCB), cable, and wire connections in the plasma power supply.

The wire harness that connects the VDC3 PCB is held by a clip in the plasma power supply. The wiring harness includes the arc voltage wires and the power wires.
