90 FOREWORD
91 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
92 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
93 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
94 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
95 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
96 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
97 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
98 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
99 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
100 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
101 consensus of opinion on the relevant subjects since each technical committee has representation from all
102 interested IEC National Committees.
103 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
104 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
105 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
106 misinterpretation by any end user.
107 4) In order to promote international uniformity, IEC National Committees undertake to app ly IEC Publications
108 transparently to the maximum extent possible in their national and regional publications. Any divergence between
109 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
110 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
111 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
112 services carried out by independent certification bodies.
113 6) All users should ensure that they have the latest edition of this publication.
114 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
115 members of its technical committees and IEC National Committees for any personal injury, property damage or
116 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
117 expenses arising out of the publication, use of, or reliance upon, this IEC Public ation or any other IEC
118 Publications.
119 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
120 indispensable for the correct application of this publication.
121 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
122 patent rights. IEC shall not be held responsible for identifying any or all such patent rights

143 INTRODUCTION
144 In the context of the fast evolution of radiocommunication technologies and the long lifetime of
145 low voltage equipment, this document proposes a method to simplify the updating of
146 radiocommunication devices within existing host equipment, including the hardware or the
147 software.
148 In this document, switchgear, controlgear, electrical accessories and assemblies are called
149 equipment.
150 The aim of this document is to limit the effort of retesting the host equipment when updating the
151 radiocommunication device in low voltage equipment (e.g. circuit-breaker, sensor, electric
152 actuator, etc.).
153 This document is intended to be referred by product standards within their requirements.
154 The test program has been elaborated based on the result of actual IEC 61000-4-39 testing by
155 equipment manufacturers and test laboratories. This test allows to characterise radiofrequency
156 band(s) and amplitude(s) which is called a capability profile. This capability profile can be used
157 to demonstrate the capability of an equipment to host various radiocommunication devices when
158 their characteristics are within the limits given by the capability profile.
159 The integration of a pre-evaluated radiocommunication device according to its technology
160 standard into a host equipment can affect its radio transmitter performances. This document
161 includes the verification of the radiocommunication functions after integration following the main
162 guidance from ETSI EG 203 367, FCC KDB 996369 D04, MIIT No.129:2021 and GRFC N 07-
163 20-03-001:2007.

171 1 Scope
172 This document defines the methods of integrating a radiocommunication device, having a
173 carrier frequency in the range covered by IEC 61000-4-39, into a host equipment with:
174 – The classification of integration categories;
175 – The verification method using a capability profile approach;
176 – The verification of the unwanted emission level of the radio transmitter.
177 This document also provides typical radiocommunication device integration use cases.
178 The object of these methods is to optimise the testing necessary when updating the host
179 equipment with a new type of radiocommunication device.
180
181 In general, this document defines the generic requirements related to the radiocommunication
182 function of an equipment. It complements the product standard of the host equipment with
183 additional characteristics, performance, and tests.
184
185 In addition, this document provides guidance on considerations to be addressed in product
186 standards including safety and security matter.
187 This document does not cover:
188 – Radiocommunication technologies (e.g. IEEE 802.11, IEEE 802.15.4);

318 4 Implementation categories
319 For the purpose of managing the update of the radiocommunication device of an equipment ,
320 the following implementation categories are defined. They depend on whether the equipment
321 has electronic circuits and where the embedded software, called also firmware, if any,
322 supporting the non-radio functions of the equipment, is hosted.
323 The electronic circuit including the embedded software if any supporting the non-radio functions
324 of the host equipment can be either of:
325 a) Integrated fully or partially into the radiocommunication device or
326 b) Hosted only on the equipment, separately from the radiocommunication device or electronic
327 circuits without embedded software.
328 NOTE For the purpose of this document, the term “electronic circuit” excludes circuits in which all components are
329 passive (including diodes, resistors, varistors, capacitors, surge suppressors, inductors).
330 Five categories are defined as follows:
331 1) Category 0: Equipment composed of a host part without electronic circuits and a
332 radiocommunication device intended to monitor and transmit the contact position,
333 actuator position or similar signal.
334
335 2) Category 1: The radiocommunication device is hosting the embedded software of the
336 equipment (a)) including the radiocommunication functions as illustrated in Figure 1 and
337 Figure 2.
338
339 Figure 1 – Example of radiocommunication implementation category 1
340 Within the equipment, the embedded software can be distributed in several microcontroller
341 units (MCU) as shown in Figure 2. If one of them is also hosting the radiocommunication
342 capabilities, then the equipment falls in category 1.
