This image shows an example label that shows the symbols and connectors on the rear of the plasma power supply.
1 EtherCAT®-out connection
2 EtherCAT-in connection
3 RS-422 connection
4 - RS-422 connection
5 Controller Area Network (CAN) connection
6 Computer Numerical Control (CNC) discrete
7 Ethernet Local Area Network (LAN) port
8 Expansion Printed Circuit Board (PCB) connectors: Necessary for redundant remote on-off feature, alternate 24 VDC power input, and analog estimated arc voltage output.
9 Power connection
10 - Negative connection
11 + Work connection
12 Pilot arc connection
13 Coolant supply (green)
14 Coolant return (red)
15 Pilot arc routing hole
16 - Negative connection routing hole
17 + Positive connection routing hole
* Use this routing hole for the following cords, cables, and leads: power, RS-422, CNC discrete, EtherCAT-in, EtherCAT-out, Ethernet LAN cable with expansion PCB cable, and CAN.
  1. Connect the coolant-hose assembly to the plasma power supply from the gas connect console.

    Tighten each nut until snug.

    This image shows the coolant-hose assembly that goes between the plasma power supply and cooler.
    Note:

    The coolant-hose assembly includes one coolant-supply hose with green bands and one coolant-return hose with red bands.

    Refer to Coolant-hose assemblies (plasma power supply to gas connect console) for lengths and part numbers.

  2. Connect the 120 VAC power cable to the plasma power supply from the gas connect console.

    Make sure this connection is tight.

    This image shows the 120 VAC power cable.
    Note:

    At least one 120 VAC power cable is necessary for all cutting systems. Some cutting systems use one 120 VAC power cable and one 220 VAC power cable.

    Refer to Power cable, 120 VAC for lengths and part numbers.

  3. Connect the CAN cable to the plasma power supply from the gas connect console.

    Make sure this connection is tight.

    This image shows theController Area Network cable.
    Note:

    Refer to CAN cables for lengths and part numbers.

  4. Connect the pilot-arc cable to the plasma power supply from the gas connect console.

    Tighten the screw until snug.

    This image shows the pilot-arc cable.
    Note:

    Refer to Pilot-arc cables with strain relief for lengths and part numbers.

  5. Connect the negative cable to the plasma power supply from the gas connect console.

    Tighten the nut until snug.

    1. Remove the inner nut from the strain relief assembly on the negative cable.
    2. Put the cable and strain relief nut for the negative cable through the hole in the sheet metal panel.
    3. Put the inner nut from the strain relief assembly over the end of the negative cable.
    4. Tighten the inner nut to the strain relief nut for the negative cable.
    Figure 2. Negative cable with strain relief
    This image shows the negative cable with strain relief.
    1 Outer nut
    2 Strain relief nut
    3 Inner nut
    4 To plasma power supply
    5 To gas connect console
    * The sheet metal of the internal console panel intersects here.
    Note:

    Refer to Negative cables with strain relief for lengths and part numbers.

  6. Connect the work cable to the plasma power supply from the cutting table.

    Tighten the nut until snug.

    Figure 3. Work cable with strain relief
    This image shows the work cable .
    1 This end goes to the plasma power supply.
    2 This end goes to the cutting table.
    Note:

    At least one work cable is necessary for all cutting systems. Some cutting systems use two work cables.

    Refer to Work cables for lengths and part numbers.
