Connect to the plasma power supply with discrete

Do these steps to connect the plasma power supply to the Computer Numerical Control (CNC) with discrete cables.

Pinouts for the discrete interface cables

  1. Remove the rear panel of the plasma power supply.

    Refer to Remove external panels from the system components.

  2. Put End A of the discrete cable through the hole in the bottom of the rear compartment in the plasma power supply.
  3. Connect J14 and J19 to their respective connectors on the control Printed Circuit Board (PCB) in the plasma power supply.
  4. Connect End B of the discrete cable to the CNC.
  5. Make sure that the shield wire that connects End B of the discrete cable to the CNC chassis ground is correctly installed.
  6. Put End A of the discrete cable for the expansion PCB through the hole in the bottom of the rear compartment of the plasma power supply.
  7. Connect End A of the discrete cable for the expansion PCB to the J4 connector on the expansion PCB.
  8. Connect End B of the discrete cable for the expansion PCB to the CNC chassis ground.
  9. Make sure the shield wire that connects End B of the discrete cable for the expansion PCB to the CNC chassis is correctly installed.
  10. Install the rear panel of the plasma power supply.
