WARNING

ELECTRIC SHOCK can kill.

• Have a qualified electrician install and service this equipment.

•Turn the input power off at the fuse box before working on this equipment.

•Do not touch electrically hot parts.

ed. A ground terminal marked with the symbol is mounted on the case bottom directly behind the input power switch for this purpose. The ground lead of the input power cord that is attached to the machine must be connected to this ground terminal. See the National Electric Code for details on proper grounding methods. Install in accordance with all local and national electrical codes.

INPUT POWER CORD CONNECTOR INSTALLATION

The Pro-Cut 55 is supplied with one 11 foot (3.35m) #8 AWG 3 lead input power cord already connected to the machine. A cord connector provides a strain relief for the input power cord as it passes through the left rear access hole. The cord connector is designed for a cord diameter of .40 - 1.03 in (10.2 - 26.2mm) if it becomes necessary to install a different input cord. See Figure A.1.

For three phase connection: Replace the input power cord with a #10 AWG 4 lead cable.

Connect the leads of the cable to a fused power panel. Make sure the green lead is connected to the panel and the panel is connected to a good earth ground.

Install in accordance with all local and national electric codes.

The Pro-Cut 55 should be connected only by a quali- fied electrician. Installation should be made in accor- dance with the U.S. National Electrical Code, all local codes, and the information detailed below.

INPUT WIRE AND FUSE SIZE

Fuse the input circuit with the super lag fuses or delay type circuit breakers recommended on the Technical Specifications page. Choose an input and grounding wire size according to local or national codes; also see the Technical Specifications page. Using fuses or circuit breakers smaller than recommended may result in “nuisance” shut-offs from inrush currents, even if you are not cutting at high currents.
