INTRODUCTION

1.0 Safety Summary

High current, voltage, and rotating parts can cause serious or fatal injury. The use of electric machinery, like all other uses of

concentrated power and rotating equipment, may be hazardous. Installing, operating, and maintaining electric machinery

should be performed by qualified personnel, in accordance with applicable provisions of the National Electrical Code and

sound local practices. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates

safety standards of design, manufacture, and intended use of the instrument. Dynapar assumes no liability for the customer's

failure to comply with these requirements.

Rotating Machinery

Avoid contact with rotating parts. Avoid by-passing or rendering inoperative any safety guards or protection devices. Avoid

extended exposure in close proximity to machinery with high noise levels. Use proper care and procedures in handling, lifting,

installing, operating and maintaining the equipment.

Safe maintenance practices with qualified personnel is imperative. Before starting maintenance procedures, be positive that, (1)

equipment connected to the shaft will not cause mechanical rotation, (2) main machine windings have been disconnected and

secured from all electrical power sources, and (3) all accessory devices associates with the work area have been de-energized.

If high potential insulation test is required, follow procedures and precautions outlined in NEMA standards MG-1.

Improperly grounding the frame of the machine can cause serious or fatal injury to personnel. Grounding of the machine frame

and structure should comply with the National Electrical Code and with sound local practices. Check wiring diagram before

connecting power.
