Remove internal wires (3-phase models)

The image shows the wire types with callouts.
1 Ground wires
2 Wires that go from the power switch to the power cord
3 Wires that go from the power switch to the power Printed Circuit Board (PCB)

For these steps, refer to The 3-phase wire connections in the plasma power supply and Internal ground wire connections.

  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 (3-phase).
  2. From the power PCB side, disconnect the 3 wires that go from the power switch to the power PCB:
    • Brown wire with white stripe
    • Black wire with white stripe
    • White wire with black stripe
    Note:

    If your system contains a white wire with a brown stripe, replace it with the brown wire with a white stripe contained in the kit.

  3. From the fan side, disconnect the 3 wires that go from the power switch to the power cord connection points on the center panel:
    • Brown wire
    • White wire
    • Black wire
  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:
    • Air filter assembly
    • Ground clip on the rear panel
    • Magnetics assembly base plate
