FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC

Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62386-220 has been prepared by IEC technical committee 34:

Lamps and related equipment.
The text of this International Standard is based on the following documents:
FDIS Report on voting
34/577/FDIS 34/591/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

lighting interface, can be found on the IEC website.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

INTRODUCTION

IEC 62386 contains several parts, referred to as series. The 1xx series includes the basic

specifications. Part 101 contains general requirements for system components, Part 102

extends this information with general requirements for control gear and Part 103 extends it

further with general requirements for control devices.

The 2xx parts extend the general requirements for control gear with lamp specific extensions

(mainly for backward compatibility with Edition 1 of IEC 62386) and with control gear specific

features.

The 3xx parts extend the general requirements for control devices with input device specific

extensions describing the instance types as well as some common features that can be

combined with multiple instance types.

This first edition of IEC 62386-220 is intended to be used in conjunction with IEC 62386-

101:2014, IEC 62386-101:2014/AMD1:2018, IEC 62386-102:2014 and

IEC 62386-102:2014/AMD1:2018 and with the various parts that make up the IEC 62386-2xx

series for control gear. The division into separately published parts provides for ease of future

amendments and revisions. Additional requirements will be added as and when a need for

them is recognised.
The setup of the standards is graphically represented in Figure 1 below.

This document, and the other parts that make up the IEC 62386-200 series, in referring to any

of the clauses of IEC 62386-1XX, specifies the extent to which such a clause is applicable;

the parts also include additional requirements, as necessary.

Where the requirements of any of the clauses of IEC 62386-1XX are referred to in this

document by the sentence "The requirements of IEC 62386-1XX, Clause "n" apply", this

sentence is to be interpreted as meaning that all requirements of the clause in question of

Part 1XX apply, except any which are clearly inapplicable.

The standardization of the control interface for control gear is intended to achieve compatible

co-existence between electronic control gear and lighting control devices, below the level of

building management systems. This document describes a method of implementing control

gear.
