The cover on the machine interface receptacle prevents dust and moisture from damaging
the receptacle when not in use. This cover (127204) should be replaced if damaged or
lost.
2. Connect the machine interface cable CPC to the power supply. (See Figure 52 on page 183.)
3. Terminate the machine interface cable spade terminals inside the electrical enclosure of listed and certified torch
height controllers (THCs) 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.
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.
