This field service bulletin covers the installation of a 25 ft (7.6 m) or 50 ft (15.2 m) machine interface cable terminated
with spade connectors. If you want to connect the Powermax system to Hypertherm’s Edge Ti or Sensor PHC products,
order part number 123896 for a cable already terminated with the appropriate D-sub connector.
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).
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. Terminate the machine interface cable inside the electrical enclosure of listed and certified torch height controllers
or CNC controllers 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 below. The table
on the next page provides details about each signal type.
