Remove internal wires (1-phase models)

The image shows the wires with callouts.
1 Ground wires
2 Wires that go from the power switch to the power cord (CSA) or Electromagnetic Interference (EMI) Printed Circuit Board (PCB) (CE/CCC)
3 Wires that go from the power switch to the power PCB

For these steps, refer to the images in Install internal wires (1-phase models).

  1. Complete the following procedures:
    1. Set the power switch to OFF (O), disconnect the power cord from the power source, and disconnect the gas supply.
    2. Remove the plasma power supply cover and handle.
    3. Remove the component barrier.
    4. Remove the power switch (1-phase).
  2. From the power board side, disconnect the power switch black wire and white wire from the power board.
  3. From the fan side, disconnect the power switch brown wire and blue wire from these locations:
    • CSA models: Power cord connection points on the center panel
    • CE/CCC models: "SW OUT" side of the EMI PCB
  4. Disconnect the 3 ground wires from the ground stud on the center panel.
    Note:

    If there are ground wires from the machine interface port or RS-485 connector, leave those terminals in place on the ground stud.

  5. Disconnect the other end of each ground wire from these locations:
    • Air filter assembly
    • Ground clip on the rear panel
    • Magnetics assembly base plate
