70 FOREWORD
71 1) The International Electrotechnical Commission (IEC) is a worldwide organization for
72 standardization comprising all national electrotechnical committees (IEC National
73 Committees). The object of IEC is to promote international co-operation on all questions
74 concerning standardization in the electrical and electronic fields. To this end and in addition
75 to other activities, IEC publishes International Standards, Technical Specifications, Technical
76 Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
77 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National
78 Committee interested in the subject dealt with may participate in this preparatory work.
79 International, governmental and non-governmental organizations liaising with the IEC also
80 participate in this preparation. IEC collaborates closely with the International Organization
81 for Standardization (ISO) in accordance with conditions determined by agreement between
82 the two organizations.
83 2) The formal decisions or agreements of IEC on technical matters express, as nearly as
84 possible, an international consensus of opinion on the relevant subjects since each technical
85 committee has representation from all interested IEC National Committees.
86 3) IEC Publications have the form of recommendations for international use and are accepted
87 by IEC National Committees in that sense. While all reasonable efforts are made to ensure
88 that the technical content of IEC Publications is accurate, IEC cannot be held responsible
89 for the way in which they are used or for any misinterpretation by any end user.
90 4) In order to promote international uniformity, IEC National Committees undertake to apply
91 IEC Publications transparently to the maximum extent possible in their national and regional
92 publications. Any divergence between any IEC Publication and the corresponding national
93 or regional publication shall be clearly indicated in the latter.
94 5) IEC itself does not provide any attestation of conformity. Independent certification bodies
95 provide conformity assessment services and, in some areas, access to IEC marks of
96 conformity. IEC is not responsible for any services carried out by independent certification
97 bodies.
98 6) All users should ensure that they have the latest edition of this publication.
99 7) No liability shall attach to IEC or its directors, employees, servants or agents including
100 individual experts and members of its technical committees and IEC National Committees
101 for any personal injury, property damage or other damage of any nature whatsoever, whether
102 direct or indirect, or for costs (including legal fees) and expenses arising out of the
103 publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
104 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced
105 publications is indispensable for the correct application of this publication.
106 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may
107 be the subject of patent rights. IEC shall not be held responsible for identifying any or all
108 such patent rights.
109 International Standard IEC 61820-1-2 has been prepared by IEC technical committee 97:

129 INTRODUCTION
130 This document is a part of a multipart standard that describes the minimum requirements for
131 the lifecycle of an Aeronautical Ground Lighting system including design, installation,
132 commissioning, maintenance, decommissioning and disposal.
133 The series circuit normally operates with a constant current and a load dependent variable
134 voltage. The protective measures for series circuits according to this standard are adapted to
135 that supply concept and the extreme long cables in the field. They are based in principle on an
136 IT supply concept (floating and separated from ground) and the protection against direct contact
137 to any live part at least for the primary circuit and SELV or PELV power supply feeding the light
138 fixtures or other loads of the series circuit. In recognition of possible aviation hazards, an
139 automatic disconnection of the AGL system in a case of an electrical failure is not required in
140 general (see details in Part 1).
141 People involved in work on AGL electrical systems shall be knowledgeable of the spec ific risks
142 and the safety procedures involved in the work related to the applied system design. It is
143 strongly recommended to do a work safety risk analysis considering all local circumstances to
144 define safe work procedures and training to the personnel.
145 Note 1: For specifications on SELV/PELV power supplies for AGL systems, see IEC 62870.
146 Note 2: Local/national regulations can be different to these standard provisions.

312 be used with.
313 For the primary circuit, the maximum output voltage of the power supply shall be used for the
314 voltage level to earth.
315 Cable selection shall be chosen to be suitable for the circuit nominal current.
316 Note: Information on series cable used for 6,6A AGL systems is given in IEC TS 62100.
317 4.11.2 Screened (shielded) cables for the primary circuit
318 Where screened cables are used, the screen shall be continuous over the full length of the cable and
319 be bonded to earth using ground rods, at regular intervals along the entire circuit loop.
320 Note 1: Where shielded cables are used and powerline communication are required, the
321 manufacturer of the powerline communication system should be consulted on shield
322 specifications.
323
