20、see note 2) with ratings and other characteristics to enable the proper and safe selection and installation of electrical equipment related to any supply of electricity. The object of this standard is to: provide general requirements for marking of the characteristics related to any supply system, s
21、uch as voltage, current, frequency and power without any restrictions; provide technical committees with uniform methods for the marking of electrical ratings of products. This basic safety publication is for general application by relevant technical committees when specifying minimum markings of ra
22、tings related to any electrical supply of equipment, sub-assemblies and components. Relevant technical committees may specify additional requirements for the marking of supply characteristics. NOTE 1For further markings see ISO/IEC Guide 51 1 1) . NOTE 2For the definition of electrical equipment see

This marking shall be
29、 legible, visible and durable throughout the anticipated life of the equipment. Marking shall not be placed on parts intended to be removed, unless it is part of an enclosure which is intended to be removed to install the equipment and must be replaced (see notes 1, 2 and 3). Some equipment has a ne
30、ed for marking both input and output characteristics. In such cases consideration shall be given by the relevant technical committee to providing markings for output as well as for input characteristics. 1) Figures in square brackets refer to the bibliography given in Annex B.EN 61293:1994 4 BSI 03-
31、1999 Some electrical equipment may be designed for use on more than one supply voltage or frequency. On some equipment the user may be required to make adjustments for use on a supply system with a given nominal voltage. Some equipment is designed to operate on several nominal voltages or over a vol
32、tage range without any adjustment and is marked accordingly. The details of the method of marking shall be the responsibility of the relevant technical committees. Marking of equipment shall be uniform and consistent with the preparation of documents used in electrotechnology as given in IEC1082-1.
33、Ratings shall be marked with standard abbreviations according to IEC445 or with standard graphical symbols taken from IEC417, IEC617 or ISO7000. Physical quantities shall be expressed using only the numerical value and their decimal multiples and submultiples followed by the unit symbol as specified
34、 in IEC27, ISO31-0 and ISO1000. Dimensions and tolerances shall be indicated in an unambiguous manner (see note 4). NOTE 1The choice of material, method and location of the marking or further requirements are the responsibility of the relevant technical committee. NOTE 2Additional markings may be pu
35、t on the packaging and/or given in an instruction sheet which accompanies the equipment. NOTE 3Tests for durability of marking, if required, are specified in the relevant product standard. NOTE 4For examples see IEC/ISO Directives Part 3 2. 3.2 Marking of electrical equipment with its characteristic
36、s Equipment shall be marked as specified in 3.1 with rated values and other characteristics related to any electricity supply. Each technical committee shall select the characteristics listed in 3.2 necessary to enable proper and safe application of equipment. Ratings and other characteristics which
37、 are not necessary may be omitted. For products too small to accommodate a rating plate, colour identification or other means according to a standard or a recognized code should be used. 3.2.1 Characteristics of supply systems Equipment shall be marked with the relevant characteristics of the supply
38、 system to which it has to be connected as follows: kind of supply system (AC, DC,), see IEC 38; number of phase conductors (e.g. 1, 2, 3); other designated conductors (e.g. N, M, PE, see IEC 445); voltage corresponding to the supply system (see IEC 38). Capital letters without full stops shall be u
39、sed. Alphanumeric notations may be replaced by graphical symbols according to IEC 417. Examples for the recommended applications of these rules, also for the sequence of order and the separation of the characteristics by a solidus “/” are given in Table A.1, Annex A. The alternative symbol for marki
40、ng of direct current (DC) with a single line (see No. 02-02-01, form 1, IEC617-2) shall not be used. 3.2.2 Rated values of equipment rated voltage in volts (V); rated frequency in hertz (Hz); rated current in amperes (A); and/or rated input and/or output power in watts (W) or voltamperes (VA). Stand
41、ard multiplier abbreviations are permitted, as shown in Table A.1, Annex A. NOTEThe relevant technical committee may specify markings for further characteristics, for example: IP code according to IEC 529 3; class of equipment according to IEC 536 4.EN 61293:1994 BSI 03-1999 5 3.3 Sequence of rated
42、values and other characteristics If a given sequential order is needed, or the space available is restricted, for example, to one line, the following sequence is recommended: characteristics of supply system (3.2.1); rated values and unit symbols (3.2.2); other characteristics. Example: 3/N/PE 400/2
43、30 V50Hz. For ratings which are listed vertically a horizontal line may be used to avoid confusion (see Table A.1). 3.4 Representation of values Each indication within the marking shall consist of the numerical value followed by the unit symbol. If no confusion exists, the unit symbol may be omitted
44、. 3.4.1 Single value Each rating indication shall consist of: a single numerical value; a unit symbol. Example: 60kV. 3.4.2 Two and more values Equipment suitable for use on any of several specified rated values of input characteristics which requires necessary manual adjustment for operation shall
45、be marked as follows: numerical values separated by a solidus (/) in a consistent sequential order; unit symbol. Example: 24/12/6V. For equipment which may be used on any of various values of voltages or frequencies but when the switching between the values is automatic, the markings shall be follow
46、ed by the capital letters AUTO, which may be replaced by the following graphical symbol: NOTE 1Switches, or other selector devices, on the equipment used to set it for the different values should be clearly marked so that it is obvious which values are set. NOTE 2A descending order of values is reco
47、mmended. 3.4.3 Range of values Equipment with a range of rated values (e.g. rated voltages), so that it can be used within a specified range of values without any adjustment, and which is designated by the lower and higher end of the range, shall be marked with: the end values separated by three dot
48、s (.) or hyphen (-); the unit symbol. NOTE 1See 3.1 regarding the requirement for uniformity and consistency between the markings and the documentation. NOTE 2An ascending order of values is recommended. 4 Application Examples of marking meeting the requirements given in clause 3 are represented in
49、Table A.1, Annex A. Further applications should be derived from these examples.
