Connection Type

Because of the high amperage draw from this machine, we recommend that you hardwire it directly to your circuit breaker and install a locking shut-off lever (see Figure 4) near the machine as a way to quickly disconnect the power and prevent accidental starting. We DO NOT recom- mend using an extension cord with this machine.

Figure 4. A power disconnect is preferable to

high current plugs and receptacles.

Your Shop Circuit Capacity

Always check to see if the wires in your circuit are capable of handling the amperage draw from your machine, as well as any other machines that could be operating on the same circuit. If you are unsure, consult a qualified electrician.

Grounding

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric cur- rent. This machine must be equipped with an electric cord that has an equipment grounding conductor. This conductor must be grounded in accordance with all local codes and ordinances.

Improper connections of the electrical-grounding conductor increases the risk of electric shock. Check with a qualified electrician or one of our service personnel if you do not understand the grounding instructions, or if you doubt the machine is properly grounded.

Electrocution or fire could result if this machine is not grounded correctly or if your electrical con- figuration does not com- ply with local and state codes. Ensure compliance by checking with a quali- fied electrician!

Phase Converter

When using a phase converter, the power from the manufactured power leg (sometimes called the wild wire) can fluxuate. Connect the manu- factured power leg to the S terminal to prevent damage to the transformer. The wire from the S terminal can handle some fluxuation because it goes directly to the motor. The power going to the R and T terminals goes to the transformer and must be consistent to prevent damage.

Extension Cords

Because of the high amperage draw from this machine, we do not recommend the use of exten- sion cords. Instead, position your equipment near installed wiring to eliminate the need for exten- sion cords.
