3、onal foreword This British Standard is the English language version of EN 60204-1:1997. It is identical with IEC 60204-1:1997. This British Standard supersedes BS EN 60204-1:1993 which remains current for use as a reference standard with BS EN 60204-311). The UK participation in its preparation was
4、entrusted to Technical Committee GEL/44, Safety of machinery electrotechnical aspects, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK inte
5、rests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. From 1 January 1997, all IEC publications have the number 60000 added to the old number. For insta
6、nce, IEC 27-1 has been renumbered as IEC 60027-1. For a period of time during the change over from one numbering system to the other, publications may contain identifiers from both systems. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which
7、 lists normative references to international publications with their corresponding European publications. The British Standards which implement international or European publications referred to in this document may be found in the BSI Standards Catalogue under the section entitled “International St
8、andards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Sta
9、ndard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, the EN title page, pages 2 to 66, an inside back cover and a back cover.

19、ocument 44/205/FDIS, future edition 4 of IEC 60204-1, prepared by IEC TC 44, Safety of machinery: Electrotechnical aspects, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60204-1 on 1997-10-01. This standard has been prepared under a mandate given to CEN/CENELEC by
20、the European Commission and the European Free Trade Association and covers essential requirements of the following EC Directives: Low Voltage Directive (73/23/EEC); Machinery Directive (89/392/EEC). This European Standard supersedes EN 60204-1:1992 and its corrigendum December 1993. Significant tech
21、nical differences have resulted from the amendments to the Machinery Safety Directive in 1991 covering mobility and lifting, and in 1993 covering safety components. The following dates were fixed: Annexes designated “normative” are part of the body of the standard. Annexes designated “informative” a
22、re given for information only. In this standard, Annex ZA is normative and Annex A, Annex B, Annex C, Annex D and Annex E are informative. Annex ZA has been added by CENELEC. This standard has the status of a horizontal standard (type B in CEN) and may be used as a reference standard by technical co
23、mmittees in CEN and in CENELEC in the preparation of product family standards or dedicated product standards (type C in CEN as defined in EN 414:1992, 3.1) for machines. The requirements of this standard can also be applied by the supplier of a machine for which no product family or dedicated produc
24、t standard exists. Where a product family or dedicated product standard exists, its requirements take precedence over the requirements of this standard. EN 60204-1 gives a large number of general requirements that may or may not be applicable to the electrical equipment of a particular machine. A si
25、mple reference without any qualification to the complete standard EN 60204-1 is therefore not sufficient. Choices need to be made to cover all requirements of EN 60204-1. A technical committee preparing a product family or a dedicated product standard (type C in CEN) and the supplier of a machine fo
26、r which no product family or dedicated product standard exists, should use this standard; a) by reference; and b) by selection of the most appropriate option(s) from the requirements given in the relevant clauses; and c) by modification of certain clauses as necessary where the particular requiremen
27、ts for the equipment of the machine are adequately covered by other relevant standards, providing the options selected and the modifications made do not adversely affect the level of protection required for that machine according to the risk assessment. When applying the three principles a), b) and
28、c) listed above, it is recommended that; reference be made to the relevant clauses and subclauses of this standard 1) that are complied with, indicating where relevant the applicable option; 2) that have been modified or extended for the specific machine or equipment requirements; and reference be m
29、ade directly to the relevant standard, for the requirements for the electrical equipment that are adequateley covered by that standard. In all cases expertise is essential to be able to: perform the necessary risk assessment of the machine; read and understand all of the requirements of EN 60204-1;

An example of a possible application of these requirements is a group of machines used in the production of discrete parts where a failure in such production machines or manufacturing systems or cells can have serious economic conse
38、quences. Figure 1 and Figure 2 have been provided as an aid to the understanding of the inter-relationship of the various elements of a machine and its associated equipment. Figure 1 is an overall block diagram of a typical manufacturing system (a group of machines working together in a co-ordinated
39、 manner) and Figure 2 is a block diagram of a typical machine and associated equipment showing the various elements of the electrical equipment addressed in this standard. Numbers in parentheses ( ) refer to clauses and subclauses in this standard. It is understood in Figure 1 and Figure 2 that all
40、of the elements taken together including the safeguards, tooling/fixturing, software, and the documentation, constitute the machine, and that one or more machines working together with usually at least one level of supervisory control constitute a manufacturing cell or system. 1 Scope This part of I
41、EC 60204 applies to the application of electrical and electronic equipment and systems to machines not portable by hand while working, including a group of machines working together in a co-ordinated manner but excluding higher level systems aspects (i.e. communications between systems). NOTE 1In th
42、is standard, the term electrical includes both electrical and electronic matters (i.e. electrical equipment means both the electrical and the electronic equipment). NOTE 2In the context of this standard, the term person refers to any individual and includes those persons who are assigned and instruc
43、ted by the user or his agent(s) in the use and care of the machine in question. The equipment covered by this standard commences at the point of connection of the supply to the electrical equipment of the machine (see 5.1). NOTE 3For the requirements for the electrical supply installation in buildin
44、gs, see IEC 60364. This part is applicable to the electrical equipment or parts of the electrical equipment that operate with nominal supply voltages not exceeding 1 000 V for alternating current and not exceeding 1 500 V for direct current, and with nominal frequencies not exceeding 200 Hz. For hig
45、her voltages or frequencies, special requirements may be needed. This part is an application standard and is not intended to limit or inhibit technological advancement. It does not cover all the requirements (e.g. guarding, interlocking, or control) that are needed or required by other standards or
46、regulations in order to safeguard persons from hazards other than electrical hazards. Each type of machine has unique requirements to be accommodated to provide adequate safety. This part specifically includes, but is not limited to, the electrical equipment of machines as defined in 3.33 (Annex A l
47、ists examples of machines whose electrical equipment may be covered by this standard). Additional and special requirements can apply to the electrical equipment of machines that: are used in open air (i.e. outside buildings or other protective structures); use, process, or produce potentially explos
48、ive material (e.g. paint or sawdust); are used in potentially explosive and/or flammable atmospheres; have special risks when producing or using certain materials; are used in mines; are sewing machines, units, and systems (which are covered by IEC 60204-31); are hoisting machines (which are covered
49、 by 60204-32). Power circuits where electrical energy is directly used as a working tool are excluded from this part of IEC 60204.
