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.

7 Fundamental design and safety requirements
7.1 Fundamental design requirements
7.1.1 General design
AGL system shall be designed so that one earth fault to ground does not cause a circuit
failure. Earth fault shall be alarmed. The AGL installation shall be designed by competent
persons to provide for:
– the proper functioning of the AGL installation for the intended use;
– the protection of persons, livestock and property.
7.1.2 AGL system design
AGL system design shall be in accordance with the relevant requirements of IEC 61820 as
applicable.
7.1.3 Equipment selection
Equipment selection shall be in accordance with the relevant requirements of IEC 61820 as
applicable.
7.1.4 Separable connections
If the voltage class level is not V1 (ELV), direct contact with a live conductor shall not be
possible by connector design, tools or maintenance procedures.
7.1.5 EMC requirements
AGL components shall comply with the requirements of IEC 61000-6-2 and IEC 61000-6-4.
7.2 Fundamental protective measures
7.2.1 Automatic disconnection
Due to the aviation risk, no automatic disconnection of the electrical supply to an AGL load
shall occur in the event of the loss of a protective measure.
Exceptions:
– The nature of the failure permits the AGL system to provide inadequate visual cues to the
pilot (e.g. open circuit detection in series circuits, overload that causes a total damage of
all light sources in a short time).
– The electrical supply to an AGL system that has been declared by airport authority as not
relevant for the aviation safety.
– A safety study shows that possible damages or electrical hazards by the operation of a
protection measure could cause a higher risk than the influence to the aviation safety.
– Any permanent exception related to a particular AGL system shall be explicitly defined in
the relevant requirements of IEC 61820.
7.2.2 Supply of the AGL loads
AGL loads should be supplied by a safety extra low voltage (SELV) or protective extra low
voltage (PELV) power source.
Exception: If the load requires a supply voltage greater than 50 V AC or 120 VDC the system
shall not be marked as ELV.
For series circuits ELV systems, IEC 62870 applies.
For parallel ELV systems, IEC 60364-4-41 applies.
Suitable and sufficient maintenance procedures shall be developed based on the installed
system.
7.2.3 General design of the AGL system
The field circuit shall be galvanically separated from the mains.
7.2.4 Protection against electrical shock caused by direct contact
Persons or livestock shall be protected against the dangers that may arise from contact with
live parts of the AGL installation.
This protection can be achieved by one of the following methods:
– preventing a current from passing through the body of any person or any livestock;
– limiting the current which can pass through a body to a non-hazardous value.
7.2.5 Selection of electrical equipment
Every item of electrical equipment shall have suitable characteristics appropriate to the values
and conditions on which the design of the AGL installation is based.
7.2.6 Insulation monitoring of the main distribution line
The insulation resistance of the primary field circuit when supplied from either a voltage class
system type V2 or V3 shall be regularly monitored at a frequency adapted to the system
condition and the measurements readily available to competent persons such as maintenance
personnel.
The airport authority (duty holder) is responsible for identifying and maintaining an
appropriate insulation resistance level sufficient to prevent danger to persons and livestock,
or to take alternative mitigation measures.
7.2.7 Protection against electrical shock caused by indirect contact
Each exposed conductive part of the AGL equipment shall be connected to a local
equipotential bonding system unless the equipment is located in the secured L1 area and
connected to a V1 ELV supply. The extent of the local equipotential bonding shall incorporate
all parts accessible by a person at the same time.
The equipotential bonding shall be designed so that the maximum touch voltage between
parts accessible by a person at the same time shall not exceed 50 V AC.
– 14 – IEC 61820-1:2019 © IEC 2019
7.2.8 Protection against transient overvoltages of atmospheric origin
A risk assessment should be carried out in accordance with IEC 62305-2.
To prevent damage to circuit components, all AGL circuits shall include suitable overcurrent
protections.
8 General installation requirements
8.1 Labelling
Each item of AGL equipment shall be visually labelled to provide clear circuit identification.
The identification is consistent throughout the full length of the AGL circuit. The labelling shall
be provided at each location where maintenance or repair may be performed (e.g. power
vaults, service pits, transformer pits, distribution boxes, etc.). The labelling shall be suitable
for the environmental requirements of the installation location. The labelling is to be legible
over the equipment lifetime.
NOTE In addition, electronic tags can be used for lifecycle management.
8.2 Cable installation
AGL cables shall be either installed in ducts or directly buried at a sufficient depth to prevent
danger to persons or livestock. Where direct burial is used, the cables shall be buried in
suitably sieved sand, or a similar material, to prevent damage.
A warning device shall be installed over buried ducts or cables. For ducts inside concrete, this
device is not mandatory.
The minimum depth of cover above the duct or cable for a type L1 location shall be in
accordance with Table 3. Where AGL cables are installed in type L2 locations, a greater depth
may be required.

Partie 1: Principes fondamentaux
AVANT-PROPOS
1) La Commission Electrotechnique Internationale (IEC) est une organisation mondiale de normalisation
composée de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l'IEC). L’IEC a pour
objet de favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines
de l'électricité et de l'électronique. A cet effet, l'IEC – entre autres activités – publie des Normes
internationales, des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au
public (PAS) et des Guides (ci-après dénommés "Publication(s) de l'IEC"). Leur élaboration est confiée à des
comités d'études, aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les
organisations internationales, gouvernementales et non gouvernementales, en liaison avec l'IEC, participent
également aux travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO),
selon des conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l'IEC concernant les questions techniques représentent, dans la mesure
du possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l'IEC
