NOTE
The cover on the machine interface receptacle prevents dust and moisture
from damage when not in use. This cover should be replaced if damaged or
lost. 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 machine interface cable to the power supply.
Refer to the following table when connecting the CUT system to a torch height controller or
CNC controller with a machine interface cable.
