BRITISH STANDARD BS EN 60204-1:1998 IEC 60204-1: 1997 Safety of machinery Electrical equipment of machines Part 1: General requirements The European Standard EN 60204-1:1997 has the status of a British Standard ICS 13.110; 29.020; 31.020 Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 01:17:20 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS EN 60204-1:1998 This British Standard, having been prepared under the direction of the Electrotechnical Sector Board, was published under the authority of the Standards Board and comes into effect on 15 November 1998 © BSI 05-1999 ISBN 0 580 30668 2 National 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 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 interests 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 instance, 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 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 Standards 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 Standard does not of itself confer immunity from legal obligations.

This standard has been prepared under a mandate given to CEN/CENELEC by 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 technical 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” are 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 committees 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 product 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 simple 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 for 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 requirements 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 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 made 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; latest date by which the EN has to be implemented at national level by publication of an identical national standard or by endorsement(dop) 1998-11-01 latest date by which national standards conflicting with the EN have to be withdrawn(dow) 2000-07-01 NOTEEN 60204-1:1985 remains applicable for use with EN 60204-3-1:1990. Licensed Copy: sheffieldun sheffieldun, na, Thu Nov 09 01:17:20 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 60204-1:1997 © BSI 05-19993 choose the applicable requirements from EN 60204-1 where alternatives are given; identify alternative or additional particular requirements that differ from or are not included in the requirements of EN 60204-1, and that are determined by the machine and its use; and specify precisely those particular requirements. Figure 2 of EN 60204-1 is a block diagram of a typical machine and can be used as the starting point of this task. It indicates the clauses and subclauses dealing with particular requirements/equipment. However EN 60204-1 is a complex document and the use of the following table will give help in the finding of a required area in this standard and gives reference to other relevant standards. Clauses and subclauses of EN 60204-1 where action should be considered (shown by X) with respect to: a) selection from the measures given; b) additional requirements; c) different requirements; d) other standards that can be relevant SubjectClause or subclause a)b)c)d)a Scope1XEN 50014 to EN 50020 General requirements4XXXEN 292, EN 1050 Supply disconnecting (isolating) device 5.3X Excepted circuits5.3.5XX Prevention of unexpected start up, isolation 5.4 5.5 5.6 XXXEN 1037 Protection against electric shock 6XHD 384.4.41 S2 Emergency operations9.2.5.4XXEN 418, EN 1050, EN 954-1, (IEC 61508) Two-hand control9.2.5.7XXEN 574, EN 954-1 Cableless control9.2.7XXX Control functions in the event of failure 9.4XXXEN 1050, EN 954-1 (IEC 61508) Position sensors10.1.4XXXEN 1088, EN 954-1 Colours and markings of control devices, indicators 10.2, 10.3 consistency of control response; ease of maintenance. High performance is not to be obtained at the expense of the essential factors mentioned above. 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 consequences. 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 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 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 IEC 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 this 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 instructed 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 buildings, 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 higher 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 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 lists 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 explosive 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 by 60204-32). Power circuits where electrical energy is directly used as a working tool are excluded from this part of IEC 60204.
