CHAPTER 1 

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. 

Before Installation 

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. 

Grounding 

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. 

Do Not Operate In An Explosive Atmosphere 

Do not operate the instrument in the presence of flammable gases or fumes. Operating any electrical instrument in such an 
environment constitutes a definite safety hazard. 

Keep Away From Live Circuits 

Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by 
qualified maintenance personnel. Do not replace components with power cable connected. To avoid injuries, always 
disconnect power and discharge circuits before touching them. 

Do Not Substitute Parts Or Modify Instrument 

Do not install substitute parts or perform any unauthorized modification to the instrument. Introducing additional hazards is 
dangerous. Return the instrument to an authorized Dynapar representative for service and repair to ensure that safety features 
are maintained.
