4 EtherCAT-out1
5 RS-422 cable, 1 of 2
6 RS-422 cable , 2 of 2
7 Controller Area Network (CAN) cable
8 Power cable, 120 VAC, to the gas connect console
9 Computer Numerical Control (CNC) discrete
10 - Negative cables, 2
11 + Work cables, 2
12 Power cable, 220 VAC, to the cooler
13 Pilot-arc cable
14 Coolant supply, green
15 Coolant return, red
16 Routing hole for the pilot-arc cable
17 + Routing hole for the work cables
18 - Routing hole for the negative cables
* Use this routing hole for the following cords, cables, and leads: power, RS-422, CNC discrete, EtherCAT-in, EtherCAT-out, and CAN.
1 Refer to the label on the rear of your plasma power supply.
  1. Connect the coolant-hose assembly to the plasma power supply from the cooler.
    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 (cooler to plasma power supply) for lengths and part numbers.

  2. Connect the 220 VAC power cable to the plasma power supply from the cooler.
    This image shows the 220 VAC power cable that goes between the plasma power supply and cooler.
    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 cables, 220 VAC for lengths and part numbers.

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

  4. Connect the CAN cable to the plasma power supply from the cooler.
    This image shows theController Area Network cable.
    Note:

    Refer to CAN cables for lengths and part numbers.

  5. Connect the pilot-arc cable to the plasma power supply from the gas connect console.
    This image shows the pilot-arc cable.
    Note:

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

  6. Connect both negative cables to the plasma power supply from the gas connect console.
    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.

    1. Remove the inner nut from the strain relief assembly on each negative cable.
    2. Put the cable and strain relief nut for both negative cables through the holes in the sheet metal panel.
    3. Put the inner nut from the strain relief assembly over the end of each negative cable.
    4. Tighten the inner nut to the strain relief nut for each negative cable.
  7. Connect both work cables to the plasma power supply from the cutting table.
    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.
