18、O90 Page 4 EN 61293 : 1994 MARKING OF ELECTRICAL EQUIPMENT SAFETY REQUIREMENTS WITH RATINGS RELATED TO ELECTRICAL SUPPLY - 1 Scope This International Standard establishes minimum requirements (see note 1 ) and general rules on marking electrical equipment (see note 2) with ratings and other characte
19、ristics 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, such as voltage, current, frequency and po
20、wer 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 ratings related to any electrical supply
21、of equipment, sub-assemblies and components. Relevant technical committees may specify additional requirements for the marking of supply characteristics.

28、tings on the equipment by a suitable method, for example, by means of name-plates or labels. This marking shall be 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 in
29、tended to be removed to install the equipment and must be replaced (see notes 1, 2 and 3). Some equipment has a need 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
30、 characteristics. 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
31、or over a voltage range without any adjustment and is marked accord i ng I y. 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 giv

Physical quantities shall be expressed using only the numerica
33、l value and their decimal multiples and submultiples followed by the unit symbol as specified in IEC 27, IS0 31-0 and IS0 1000. Dimensions and tolerances shall be indicated in an unambiguous manner (see note 4). NOTES 1 responsibility of the relevant technical committee. 2 accompanies the equipment.

35、C/iSO Directives Part 3 2). 3.2 Marking of eiectricai equipment with its characteristics 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 e
36、nable proper and safe application of equipment. Ratings and other characteristics which 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 s
37、upply systems Equipment shall be marked with the relevant characteristics of the supply 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
38、 corresponding to the supply system (see IEC 38). Capital letters without full stops shall be used. Alphanumeric notations may be replaced by graphical symbols according to IEC 41 7. Examples for the recommended applications of these rules, also for the sequence of order and the separation of the ch
39、aracteristics by a solidus “/“ are given in table A.l, annex A. The alternative symbol for marking of direct current (DC) with a single line (see No. 02-02-01, form 1, IEC 617-2) shall not be used.

40、ed 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). Standard multiplier abbreviations are permitted, as shownin table A.l, annex A. NOTE - The relevant technical committee may specify mar
41、kings for further characteristics, for example: - - IP code according to IEC 529 3; class of equipment according to IEC 536 (41. 3.3 Sequence of rated values and other characteristics If a given sequential order is needed, or the space available is restricted, for example, to one line, the following
42、 sequence is recommended: - characteristics of supply system (3.2.1); - rated values and unit symbols (3.2.2); - other characteristics. Example: 3/N/PE 400/230 V 50 Hz. For ratings which are listed vertically a horizontal line may be used to avoid confusion (see table A.l). 3.4 Representation of val
43、ues 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. 3.4.1 Single value Each rating indication shall consist of: - a single numerical value; - a unit symbol. Example: 60 kV. 3.4.2 Two and more
44、 values Equipment suitable for use on any of several specified rated values of input characteristics which requires necessary manual adjustment for operation shall be marked as follows: - numerical values separated by a solidus (/) in a consistent sequential order; - unit symbol. Example: 24/12/6 V
