The reference document, together with the following common modifications prepared by the CENELEC Technical Committee TC 2, Rotating machinery, was submitted to the CENELEC members for formal vote. The text of the draft was approved by CENELEC as HD 53.8 S4 on 9 March 1993. The following dates are proposed: - latest date of announcement of the HD at national level (doa) 1993-09-01 - latest date of publication of a harmonized national standard (dop) 1994-03-01 - latest date of withdrawal of conflicting national standards (daw) 1994-03-01 For products which have complied with HD 53.8 S3:1985 and its amendment A1:1989 before 1994-03-01, as shown by the manufacturer or by a certification body, this previous standard may continue to apply for production until 1999-03-01. ENDORSEMENT NOTICE The text of the International Standard IEC 34-8:1973 and its amendment 1:1990 was approved by CENELEC as a Harmonization Document with agreed common modifications as given below. COnnoiJ HODIPICATIONS Add the following additional rules concerning the relation between terminal markings and the direction of rotation: GENERAL Terminal markings alone do not allow the mode of operation of the machine to be deduced. It should be noted that the figures are illustrations only. They do not take the place of the Rules and the arrangement of terminals in the figures is not mandatory. As IEC 34-8 does, the rules below deal with “external“ terminals, i.e. terminals at the disposal of the user (IEC 34-8, page 7, Explanatory Note) but give further details for a clear understanding of the marking itself. In the figures attached to these Additional rules, markings of winding end points which are not “external“ terminals are indicated in brackets for information purposes.

A11 terminals shall be identified by a marking. 2. The terminals to be CoMected to the supply are those having internal connections to the winding ends identified by the lobest suffix, v i r . suffix 1 with untapped single-section bindings ( e . g . see Figs. 1 and 2). 3. In any electrical machine there shall be not more than one terxinal with a given marking unless each of them is capable of performing the f u l l electrical function appropriate to that 'marking, so that either may be used for the connection (see Figure i). 4. If more than one terminal is provided to share tho current, additional numerical markings are necessary, separated by a hyphen from the suffix of the marking (see Figure 2 ) . For windings with intermediate points, if more Chan two intermediate points per section are provided, the terminals corresponding to the tappings shall be marked with the following suffixes : 5 . 3, 31, 32 4 7, 71, 72 8 * etc. (see Figure 5). Note : The rules given in IEC Publication 443, sub-clause 5.2.b, f o r tappings in a single element, cannot be applied atrictly to rotating machines with more than two Intermediate points per section : see IËC 34-8.Ti6.2.

Hulti-sectian windings 6.1 The terminals corresponding to the ends of the sections shall be marked with the following suffixes (see Figure 3 and also Figure 3 of Publ. 34-a), - first section : 1 , 2 - second section : 5 , c - third section : 9 , l O - fourth section : 1 3 , ? 4 In any section, the end point closer to the supply shall be marked with the lower numerical suffix. This applies to a l l multi-section uindings, whatever arrangements they may be meant for ( e . g . see F i g s . 7, 8, 9 and 10). 6.2 If two or more sections of a winding are connected t o a common terminal, it shall take the lowest of the suffixes of the ends connected (see Figure b ) . 7. Separate winding3 7.1 Separate windings are such that, whatever purposes they may be intended to serve, they only are used one ar a time, whether in full or partially, i . e . they are nor inrend-ac! fe:- any arrangement combining two or more windings or sectla1ls of them. 7.2 For mactiirics vith separate Windings, tfic rcquircmtbntr of C l a w 5 orrd Cluusc 4 shall apply for coch separate uinding. In addition, a l l terminals. s h l i be marked vfth numerical prefixes corresponding to the sopurate winding to rhich t h y belong, vir. : - first winding :I - second winding :.2 - third winding :3 - fourth winding :4 - etc ( see Fig. 6, and also Fig.4 of IEC Publication 34-8) . Besides, in the case of multi-speed machines, the marking of terminals for connection to the supply shall be in mccordrnce with Sub-clauses 8.2 urd 8.3.

Yulti-speed machines 8.1 I f a machine has only one winding (e.g. a Dahlander or a pole modulation uinding), the section end-points vhich are connected to the supply, when the sections are connected for the lovest speed, shall be identified by the lovest suffix. For each speed, the terminals to be connected t o the suppl). shall be marked vith a numerical prefix. The sequence of the prefixes corresponds uith the increasing speed sequence. The suffix is omitted if the marking of a terminal has a prefix (e.g. see Figs. 7 and 8, vhich respectively aro the same as Figs. 7 and 8 in IEC 34-8). 8 . 2 If a machine has separate single-section windings (e.g. see IEC 34-8, Fig.4, for 2 separate windings), the rules of Clause 7 shall apply with the sequence of prefixes corresponding to an increasing speed sequence. The tenninsls to be connected to the supply are those h3vin.c: internal connections to the winding ends identified by the louer suffix. Fcr each speed, the suffixes of the terminals t o be comicctd to the supply are omitted. 8.3 If a machine has separate windings including multi-section windings (0.6. Dahlander or pole modulation vindings), rule?= in Sub-clauses 8.1 and 8 . 2 apply in combination ( c . g . see Fig. 9 , which is the same as Fig.9 in IEC 34-8, and Fig.10'). 8 . 4 The relation between direction of rotation and alphabetical sequence of the terminal letters given in Sub-clause 5 . 1 of IEC 34-8 is valid f o r all speeds .Should in a winding two phases be switched over t o achieve this, then said switch shall be applied to terminal markings U and W and shall be applied to the arrangement for the lowest speed (e.g. see Figs 7, 8, 9 which respectively are the same as Figs 7 , S and 9 in IEC 34-8). 9 . Khrn an end of a main winding and an end of an auxiliary bindiiig are connected to the same terminal, that terminal shall be identified according t o thc'rule for the main winding (sec Figs. 11 and 12). - S o t e : Rule in Clause 9 cannot be applied to some types of small power motors. A specific terminal coding system f o r sucli motors is under consideration.
