7-4 Powermax105 Operator Manual
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 (part number 127204).
See the Parts section for more information.
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 the torch height controller or CNC controller to prevent unauthorized 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 in the figure on
the next page. The table provides details about each signal type.
