Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use a qualified electrician to ensure a safe power connection.

Once the machine is set up and assembled as previously described in this manual, it is ready to be connected to the power source.

Note About Extension Cords: Using an incorrectly sized extension cord may decrease the life of electrical components on the machine.

Note About 3-Phase Power: DO NOT use a static phase converter to create 3-phase power— it can quickly decrease the life of electrical components on the machine. If you must use

a phase converter, only use a rotary phase converter and connect the manufactured leg to the correct power connection terminal, shown in the wiring diagrams on Page 65.

To connect the mill to power:

1.Make sure the incoming power source and the power cord meet the requirements listed above.

2.Use the correct size strain relief when you feed the power cord through the bottom of the electrical cabinet.

3.Terminate the power cord as illustrated in the Electrical Box Wiring Diagrams on Pages 65–68.

4.We recommend that you connect the other end to a NEMA 6-20 plug.
