(informative) Apparatus using infra-red radiation for signal transmission or control purposes No emission requirements in the wavelength range 0,7 µm to 1,6 µm are specified for apparatus controlled by apparatus covered by this standard, but it is desirable to limit emission of the 1,014 µm Hg-line as much as possible Infra-red sensors have a very broad band frequency response and fluctuations of light intensity (caused by fluorescent lamps, for example), and of other electromagnetic radiation should be taken into account EN 60825-1 contains counsel on safety aspects Guidance and useful information on the use of infra-red communication and control devices may be found in EN 61603 (multi-part) and EN 61920 BS EN 55103-1:2009+A1:2012 EN 55103-1:2009+A1:2012 (E) - 18 - Annex E (informative) Use of apparatus near wireless microphone receivers and receiving antennas E.1 Explanation and guidance on requirements The enclosure emissions for apparatus intended to be used near the antenna of a wireless microphone have to be kept so low that it is often economically impossible for general purpose apparatus which produces any significant amount of enclosure radiation to meet them Because the frequency bands allocated to wireless microphones differ greatly among CENELEC member states, it is not possible just to specify very low limits over a particular frequency range, nor is it likely to be economic to design apparatus to have very low emission over the whole range required for all CENELEC member states (31,6 MHz to 000 MHz) The limits and frequency range applicable, and the minimum distance between the apparatus and the antenna, should therefore be agreed by the supplier and the user in each individual case Figure E.1 shows, for guidance, the interfering field strength limits that are likely to be required, at the minimum distance from the wireless microphone antenna at which the apparatus is intended to be used The limits should be met at the minimum distance from the wireless microphone antenna at which the apparatus is intended to operate The supplier should agree the frequency range(s) over which the limits have to be met Adapted from the reference given in E.2 Figure E.1 - Guidance for requirements on enclosure port emission for apparatus intended to be used near the antennas of wireless microphones - 19 - E.2 BS EN

draws a large current pulse from the mains supply in the first (occasionally the second) half-cycle of applied voltage at switch-on This current may set up magnetic induction in mains transformers or charge filter capacitors in d.c supplies, or both Incorrect design of the power supply system can lead to long breakdowns, since many fuses have to be replaced In general, but not in every case, an 'inrush-current tolerant' supply can be provided, using the appropriate class of circuit breaker (see EN 60898) instead of fuses for protection This standard does not set limits for inrush current additional to the requirements of EN 61000-3-3, but requires the manufacturer to state the maximum inrush current of apparatus, so that the supply system designer has available the relevant input data for correct design It should be noted that some apparatus is fitted with fuses or other protective devices in the mains supply circuit having current ratings considerably in excess of the true full-load current In some cases, this is due to the use of fuses with inappropriate pre-arcing time characteristics, which fail under inrush current conditions The requirement to determine and publish the maximum inrush current may lead to improvements in design in this respect Inrush current is likely to be most troublesome when power is restored to an installation after a break of a few seconds, since many ‘soft-start’ (inrush current limiter) measures (such as thermistors) not function correctly in these conditions For this reason this standard includes a requirement to state the inrush current after a short interruption of the supply, in addition to the requirement at initial switch-on Measures to control inrush currents on restoration of power include - requirement by design for a manual operation to switch on the apparatus again after a mains supply failure, NOTE For such apparatus, EN 61000-3-3 and EN 61000-3-11 have certain relaxed requirements - instruction of operators or labelling of equipment, or both, so that apparatus is manually switched off when a mains power failure occurs, - provision of auxiliary control equipment to restore mains power to groups of apparatus in timed stages - 21 - BS EN 55103-1:2009+A1:2012 EN 55103-1:2009+A1:2012 (E) Annex G (informative) Background to the standard and justification of adopted methods and limits for this standard and its companion on immunity (EN 55103-2) G.1 General The standards are not prepared exactly in accordance with the guidelines for product-family standards This is due to the wide variety of apparatus in the product family, the wide range of applications of the apparatus (directly leading to different acceptable degrees of immunity), and the wide range of EM environments in which the apparatus is used G.2 Apparatus within the scope of the standards G.2.1 Meaning and implications of 'professional' The definition of 'professional apparatus' included in EN 61000-3-2 has been adopted It has proved difficult to develop a definition which is generally acceptable, particularly now that products intended for consumer entertainment applications are also used in what are clearly recognisable as professional applications, such as electronic news-gathering Professional apparatus is generally characterized by - manufacture in small quantities (1 to 000 a year), - a high level of technical performance, carefully oriented to the application, - installation and maintenance by technically-trained persons, - not normally used in the family home It would not be correct to assume that - professional apparatus cannot be (or should not be allowed to be) purchased by any person who has the necessary financial resources, - professional apparatus is used exclusively or even mainly by 'professionals' in the sense of 'persons trained and skilled in electrical or electronic technology' For example, electronic newsgathering equipment is used by journalists, not audio or video engineers, - the above-mentioned 'high level of technical performance' applies to any arbitrarily chosen characteristic For example, the frequency response of an intercom system may be very restricted, because this is necessary in order that the overall performance of the system meets the necessary operational requirements G.2.2 Types of apparatus covered by the standards G.2.2.1 Introduction A very restricted set of examples is given because there are literally thousands of different types of product involved Even with one product type there may be great diversity For example, the product type 'audio power amplifier' includes a W amplifier with frequency response 200 Hz to kHz intended for an emergency-vehicle loud-hailer and a 3,5 kW amplifier with frequency response DC to 50 kHz intended for major pop-music events BS EN 55103-1:2009+A1:2012 EN 55103-1:2009+A1:2012 (E) - 22 - G.2.2.2 Audio apparatus Audio power amplifiers; audio low-level amplifiers; mixing desks; recording and reproducing apparatus; loudspeakers; microphones; signal-processing apparatus (compressors, expanders etc.); digital editors; installation control apparatus G.2.2.3 Video apparatus Cameras; display apparatus; mixers; distribution amplifiers; synchronisation regenerators; recording and reproducing apparatus; installation control apparatus; visual effects processors G.2.2.4 Audio-visual apparatus All audio-visual apparatus except that to which EN 55014 or EN 55015 specifically applies, or for which a product standard is being prepared G.2.2.5 Entertainment lighting control apparatus Control desks and DMX processors (but not dimmers or luminaires, to which EN 55015 applies); audio interface units; control desks for 'intelligent' luminaires; presentation control apparatus G.2.3 Technologies used in the apparatus The technologies embrace all categories of applied electronics, from purely analogue, through analogue with digital control, to purely digital, and include the use of bit-rate reduction and other coding techniques which rely on the characteristics of human responses and for which objective methods of measurement not yet exist Wired and wireless (radio and infra-red) communication and interfacing techniques are used Radio transmission (sending) equipment is excluded G.2.4 Electromagnetic environments Professional audio, video, audiovisual and entertainment lighting control apparatus is used in many different environments, in some of which special measures are necessary in order to minimise emission and/or to provide greater immunity It is impractical to deal with all these possibilities in the standard, but the provisions which have been adopted are intended to deal satisfactorily with the most likely configurations of apparatus in the commonly-encountered environments It is quite unnecessary, and economically unjustifiable, for all apparatus to be designed to cope with the most severe combination of requirements conceivable (comprising the most severe requirements demanded by all environments), so that operation in any environment is bound to be satisfactory As indicated in IEC 61000-2-3, apparatus not normally associated with a particular class of environment may affect a specific location This is because there are no definable boundaries for most environments (exceptions are screened in some way): the likelihood of interference depends on the strength of the source, the sensitivity of the victim, the distance between them and the propagation characteristics of the carrier medium The Generic Standards series are segregated by environment By contrast, most existing product (family) standards (EN 55013, EN 55014, EN 55015 and EN 55020) not mention environment explicitly, and not give different requirements for different environments Some of the product families are likely to be confined to one, or a small number of, environments, but this is not certain, and is not the case for the apparatus within the scope of EN 55103 - 23 - BS EN 55103-1:2009+A1:2012 EN 55103-1:2009+A1:2012 (E) The industry sector specifically indicated that it would not be acceptable for the standards to deal with only one or two EM environments, leaving the requirements for satisfactory service in others to be determined either by Generic Standards or by contractual agreements This is because manufacturers would have no definite requirements to refer to during product development The apparatus is used in many EM environments, including residential (but very seldom in the actual family home) It was therefore determined that the standards should deal with several environments, but that not all of the eight included in IEC 61000-2-5 needed to be considered separately The standards therefore include only five sets of requirements for different environments, and every effort has been made to minimise the differences between the requirements Considerable support has been expressed by the industry sector in some countries for the selection of five environments, and for the freedom this gives for manufacturers to choose which environments they will make their products suitable for The user is safeguarded by the requirement for the manufacturer to state these environments in the specification of the product, not in a document which is only available if specially requested G.3 Relation to Generic Standards G.3.1 General The professional audio, video, audio visual and entertainment lighting industry sector was initially encouraged to consider using the Generic Standards instead of calling for product-family standards to be developed This proposal was found to be unacceptable for the following reasons: - test conditions were not sufficiently well-defined (and it was considered unlikely that Generic Standards could include such product-specific information); - some of the test methods proposed (by reference to draft Basic Standards or other documents) were considered fundamentally inappropriate for much apparatus in the product family; - the industry sector had little influence on the content of Generic Standards, and there were justifiable fears that further changes to the drafts, and, in due course, revisions of the published Generic Standards might result in severe difficulties for the industry sector G.3.2 Emission requirements The emission requirements are harmonised with those adopted in the Generic Standards, also taking into account the information on expected disturbance levels in IEC 61000-2-5 G.3.3 Immunity requirements In a product standard for a restricted range of very similar products, it is quite simple and satisfactory for precise numerical values to be set for conformity with immunity requirements This is what was envisaged when the original guidelines for the content of product standards were drafted However, the case of a product-family standard of wide scope, including many different types of apparatus, and a wide range of functional performance requirements, was naturally not envisaged at that time Even a short consideration of the concept of applying numerical values for immunity requirements in EN 55103-2 leads to the conclusion that, if not impossible, it would certainly be an immense task technically, because of the great variety of apparatus involved and the different characteristics This is, in part, because the degree of immunity required often depends on the specific application For example, an audio amplifier for sound reinforcement requires only a modest immunity to clicks due to ESD or fast transients, whereas if the same amplifier is used in a recording studio, it requires much higher immunity BS EN 55103-1:2009+A1:2012 EN 55103-1:2009+A1:2012 (E) - 24 - The standard therefore adopts a modification of the approach used in the Generic Standards The same three conceptual failure criteria, A, B and C, are employed, and the manufacturer is required to state the amount of performance degradation for each disturbance phenomenon, in an EMC specification which is required to be supplied to the user as a matter of course, not only on specific request In this way, the user can easily determine whether the EMC specification of the product meets his needs, and whether the product as purchased meets the published EMC specification In order to secure as much uniformity as possible in published EMC specifications, Informative Annex D of the standard lists what are usually the most important product performance characteristics which may be degraded by electromagnetic disturbances This practice follows that adopted in some product-family standards produced by ETSI Particularly for video apparatus and apparatus using bit-rate reduction, objective methods of assessing the effects of disturbances are not available, and these effects are, in normal practice, assessed by well-established subjective methods developed by ITU/R (former CCIR) It is therefore necessary for the immunity standard to allow these methods to be used, for no others are available The lists of performance characteristics can be expanded at any time if a need arises G.3.4 Justification of the differences between the proposed immunity requirements and those in the Generic Immunity Standards The number of these differences has been severely restricted, but it is considered necessary that some remain: - immunity to magnetic fields: this phenomenon is one which causes actual practical difficulties where much apparatus is concentrated in a small area, such as a television studio; The methods specified in Annex A are adapted from method RE101 of MIL-STD-462-D; - common-mode disturbances on screened balanced signal lines: here, a test method is required which can be applied without disturbing the intrinsic balance of very highly symmetrical circuits (CMRR of 80 dB or more) The Basic Standard EN 61000-4-16 is not considered applicable to this product family standard; - inrush current: this phenomenon, also, is of most significance where apparatus is concentrated together It is particularly troublesome when the mains supply is restored after a brief interruption, when all of the inrush currents occur simultaneously; it is an EMC phenomenon and should be in the standard; however, it is recognised that it may simply be a matter of designing the mains supply system to accommodate the inrush currents (see 7.1 and Annex F) G.4 Other considerations G.4.1 Combinations of apparatus Professional audio, video, audiovisual and entertainment lighting control apparatus is designed so that a variable number of different sub-units may be used together in the same rack or cabinet Manufacturers cannot be expected to carry out extensive tests on every possible permutation of sub-units (which could be several thousand in number), but should strive to ensure that no unforeseen level of emission or degradation of immunity occurs with any likely combination of sub-units G.4.2 Special considerations for entertainment lighting control apparatus Unlike the other apparatus within the scope of EN 55103, much entertainment lighting dimming apparatus has been designed for many years to conform to EMC requirements, since it was considered to fall within the scope of the former Directive 76/889/EEC requiring compliance with EN 55014 These dimmers are now tested in accordance with the requirements of EN 55015, and the related luminaires (where not EMC benign) also with EN 55015 Thus it is logical that the requirements for entertainment lighting control apparatus in EN 55103 should be harmonised with the corresponding requirements of EN 55015 - 25 - G.5 BS EN 55103-1:2009+A1:2012 EN 55103-1:2009+A1:2012 (E) Contractual requirements G.5.1 General The standards comprise the essential requirements for free market access under the EMC Directive (2004/108/EC) The fact that conforming apparatus is used in an installation does not mean that the installation can be designed without consideration of EMC As noted in the standards, in certain cases, particularly where much apparatus is concentrated together, it may be necessary to specify additional tests, limits and requirements as contractual requirements, agreed between supplier and purchaser The following texts mention some of the possible contractual requirements, but others may arise in special circumstances G.5.2 Magnetic field emissions Some apparatus is very sensitive to magnetic fields, and other apparatus (such as CRT displays and switchmode power units) emits magnetic fields up to at least 50 kHz fundamental frequency, accompanied particularly by strong odd-order harmonics Contractual requirements may cover emissions, immunity or both G.5.3 Rack-mounted apparatus For individual apparatus intended for rack mounting, the emission limits and immunity requirements at 100 mm distance are most important, and normally ensure satisfactory operation In special cases, contractual requirements may be necessary, but it should clearly be understood that it is necessary to consider carefully, at the installation stage, the relative positioning of emitting and sensitive apparatus in the rack, and in adjacent racks The separation of interacting units is likely to be less costly than the adoption of complicated EMC improvements For complete rack assemblies, the limits and requirements at m distance are relevant These should allow the planning of the installation to be carried out correctly BS EN 55103-1:2009+A1:2012 EN
