Service Manual
• To use signals for arc transfer and plasma start only, use either part number 023206 (7.62m, 25feet) or part
number 023279 (15.24m, 50feet). These cables have spade connectors as shown here:
Note: The cover on the machine interface receptacle prevents dust and moisture from damaging the receptacle
when not in use. This cover should be replaced if damaged or lost (127204).
Installation of the machine interface cable must be performed by a qualified service technician. To install a machine
interface cable:
1. Turn OFF the power and disconnect the power cord.
2. Remove the machine interface receptacle’s cover from the rear of the power supply.
3. Connect the Hypertherm machine interface cable to the power supply.
4. If you are using a cable with a D-sub connector on the other end, plug it into the appropriate pin connector on the
torch height controller or CNC. Secure it with the screws on the D-sub connector.
If you are using a cable with wires and spade connectors on the other end, terminate the machine interface cable
inside the electrical enclosure of listed and certified torch height controllers or CNC controllers to prevent operator
access to the connections after installation. Verify that the connections are correct and that all live parts are
enclosed and protected before operating the equipment.
Note: The integration of Hypertherm equipment and customer-supplied equipment including interconnecting
cords and cables, if not listed and certified as a system, is subject to inspection by local authorities at the
final installation site.
The connector sockets for each type of signal available through the machine interface cable are shown below. The table
on page 3-27 provides details about each signal type.
