CONTENTS Page Foreword ii Referenced Standards. iv Amendments v IEC 61131-2.1 NEMA IA 2.2-2005 Page ii Copyright 2005 by the National Electrical Manufacturers Association. Foreword This Standards Publication is a NEMA Adopti
14、ve Standard based on Part 2 of IEC 61131, Programmable Controllers. This Standards Publication was prepared by a technical committee of the NEMA Automation Products and Systems Section. It was approved in accordance with the bylaws of NEMA and supersedes NEMA Standards Publication ICS 3-1988, Part 3
15、-304. This Standards Publication provides practical information concerning ratings, construction, test, performance, and manufacture of industrial control equipment. These standards are used by the electrical industry to provide guidelines for the manufacture and proper application of reliable produ
16、cts and equipment and to promote the benefits of repetitive manufacturing and widespread product availability. NEMA Standards represent the result of many years of research, investigation, and experience by the members of NEMA, its predecessors, its Sections and Committees. They have been developed
17、through continuing consultation among manufacturers, users, and national engineering societies and have resulted in improved serviceability of electrical products with economies to manufacturers and users. One of the primary purposes of this Standards Publication is to encourage the production of re
18、liable control equipment which, in itself, functions in accordance with these accepted standards. Some portions of these standards, such as electrical spacings and interrupting ratings, have a direct bearing on safety; almost all of the items in this publication, when applied properly, contribute to
19、 safety in one way or another. Properly constructed industrial control equipment is, however, only one factor in minimizing the hazards which may be associated with the use of electricity. The reduction of hazard involves the joint efforts of the various equipment manufacturers, the system designer,
20、 the installer, and the user. Information is provided herein to assist users and others in the proper selection of control equipment. The industrial control manufacturer has limited or no control over the following factors which are vital to safe installation: environmental conditions system design
21、equipment selection and application installation operating practices maintenance This publication is not intended to instruct the user of control equipment with regard to these factors except insofar as suitable equipment to meet needs can be recognized in this publication and some application guida
22、nce is given. This Standards Publication is necessarily confined to defining the construction requirements for industrial control equipment and to providing recommendations for proper selection for use under normal or certain specific conditions. Since any piece of industrial control equipment can b
23、e installed, operated, and maintained in such a manner that hazardous conditions may result, conformance with this publication does not by itself assure a safe installation. When, however, equipment conforming with these standards is properly selected and is installed in accordance with the National
24、 Electrical Code and properly maintained, the hazards to persons and property will be reduced. NEMA IA 2.2-2005 Page iii Copyright 2005 by the National Electrical Manufacturers Association. To continue to serve the best interests of users, NEMA is actively cooperating with other standardization orga
25、nizations in the development of simple and more universal metrology practices. In this Standards Publication, the U.S. customary units are gradually being supplemented by those of the modernized metric system known as the International Systems of Units (SI). This transition involves no changes in st
26、andard dimensions, tolerances, or performance specifications. NEMA Standards Publications are subject to periodic review. They are revised frequently to reflect user input and to meet changing conditions and technical progress. Users should secure the latest editions. Inquiries, comments, and propos
27、ed or recommended revisions should be submitted to the concerned NEMA product subdivision by contacting the: Vice President, Technical Services National Electrical Manufacturers Association 1300 North 17th Street Rosslyn, Virginia 22209 NEMA IA 2.2-2005 Page iv Copyright 2005 by the National Electri
