This machine must have a ground prong in the plug to help ensure that it is grounded. DO NOT remove ground prong from plug to fit into a two-pronged outlet! If the plug will not fit the outlet, have the proper outlet installed by a qualified electrician.

Grounding

In the event of an electrical short, grounding reduces the risk of electric shock. The grounding wire in the power cord must be properly connect- ed to the grounding prong on the plug; likewise, the outlet must be properly installed and ground- ed. All electrical connections must be made in accordance with local codes and ordinances.

Extension Cords

We do not recommend the use of extension cords. Instead, arrange the placement of your equipment and the installed wiring to eliminate the need for extension cords.

If you find it absolutely necessary to use an exten- sion cord with your machine, the extension cord must also contain a ground wire and plug pin.

110V Operation

Use at least a 12 gauge cord that does not exceed 50 feet in length!

220V Operation

Use at least a 12 gauge cord that does not exceed 50 feet in length!

Phase Converter

When using a phase converter for 3-phase, the power from the manufactured power leg (some- times called the wild wire) can fluctuate. Connect the manufactured power leg to the S terminal to prevent damage. The wire from the S terminal can handle some fluctuation 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.
