Electrical Wiring
The single phase variant of his machine is pre-wired with a cord and a NEMA 6-15 plug. See “ Wiring
Diagrams ” on page 35 for wiring the three phase variant.
To connect the machine directly to the electrical panel ( “ Hardwiring ” ), ensure an electrical disconnect is
installed near the machine so the operator or service person can easily disconnect the machine from
power.
To connect this machine with a plug and a cord, use a UL/CSA listed plug that meets the power
requirements. Organize the power cord so it does not create a tripping hazard.
The use of an extension cord is not recommended. If you need to use an extension cord to connect to a
power source, select a durable cord type with a high-temperature rating (90C° or above). Use the
minimum amount of extension cord as needed.
Minimum cord size (AWG) required based on amperage draw and length of the cord:
Amps Power Cord Length
25 feet 50 feet 75 feet 100 feet
8 to 12 14 14 12 10
12 to 15 12 12 10 10
15 to 20 10 10 10 NR
21 to 30 10 NR NR NR
*NR: Not Recommended
WARNING
Use properly sized wires that meet or exceed the power requirement of your
machine. Using undersized wires may cause overheating and increase the risk of fire
and machine damage.
