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 the next page provides details about each signal type.
