Part 7-716: Requirements for special installations or locations –
ELV DC power distribution over information and communications
technology (ICT) cable infrastructure

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.
IEC 60364-7-716 has been prepared by IEC technical committee 64: Electrical installations and
protection against electric shock. It is an International Standard.
The text of this International Standard is based on the following documents:

INTRODUCTION
For the purpose of this part of IEC 60364 (IEC 60364-7-716) the requirements of the general
Parts 1 to 6 and Part 8 of IEC 60364 apply.
The IEC 60364-7-7XX parts of IEC 60364 contain particular requirements for special
installations or locations which are based on the requirements of the general parts of IEC 60364
(IEC 60364-1 to IEC 60364-6 and IEC 60364-8). These IEC 60364-7-7XX parts are considered
in conjunction with the requirements of the general parts.
The particular requirements of this part of IEC 60364 supplement, modify or replace certain of
the requirements of the general parts of IEC 60364 being valid at the time of publication of this
part. The absence of reference to the exclusion of a part or a clause of a general part means
that the corresponding clauses of the general part are applicable (undated references).
Requirements of other 7XX parts being relevant for installations covered by this part also apply,
and circuits serving such parts are limited by the requirements of those 7XX parts.
The clause numbering of this part follows the pattern and corresponding references of
IEC 60364. The numbers following the particular number of this part are those of the
corresponding parts, or clauses of the other parts of the IEC 60364 series, valid at the time of
publication of this part, as indicated in the normative references of this document (dated
references).
If requirements or explanations additional to those of the other parts of the IEC 60364 series
are necessary, the numbering of such items appears as 716.101, 716.102, 716.103, etc.
In the case where new or amended general parts with modified numbering were published after
this part was issued, it is possible that the clause numbers referring to a general part in this
Part 716 will no longer align with the latest edition of the general part. Dated references should
be observed.

functional elements (equipment and infrastructure) that enable communication between the
core network and a customer network
716.3.4
connecting hardware
device or combination of devices used to connect cables or cable elements
716.4 Protection for safety
716.41 Protection against electric shock
716.410.3 General requirements
716.410.3.3
Only the following protective measures shall be applied:
– extra-low voltage (SELV and PELV) systems (Clause 414).
716.414.1.1
Replace the second paragraph by:
This protective measure SELV requires the following:
– limitation of the voltage to 60 V ripple free DC in dry locations and 15 V ripple free DC in all
other locations, and
– protective separation system from all circuits other than SELV and PELV circuits, and basic
insulation between the SELV system and other SELV or PELV systems, and
– for SELV systems, basic insulation between the SELV system and earth.

---------------------- Page: 9 ----------------------
– 8 – IEC 60364-7-716:2023 © IEC 2023
This protective measure PELV requires the following:
– limitation of the voltage to 60 V ripple free DC in dry locations and 15 V ripple free DC in all
other locations, and
– protective separation system from all circuits other than SELV and PELV circuits, and basic
insulation between the PELV system and other SELV or PELV systems.
NOTE 1 Where PELV is used, mitigation measures can be required to limit the sharing of LV fault currents in
accordance with ISO/IEC 30129 and IEC TR 61000-5-2. Exposed-conductive-parts of ELV DC power equipment
(such as PoE switches or converters) can be connected by a protective conductor to the main earthing terminal.
NOTE 2 The screen/shielding of the communications cabling provides functional earthing and it is not suitable for
limiting the sharing of LV fault currents.
NOTE 3 The protective measure PELV is particularly appropriate where functional equipotential bonding is used as
an EMC mitigation measure, for example where many power sourcing circuits and equipment are installed in the
same location, or where equipment is linked together from several buildings.
716.414.3.1
Add the following text:
"and IEC 61558-2-16"
716.414.3.4
Replace the first paragraph, retaining Note 1 and Note 2 which remain unchanged, by:
Certain electronic devices complying with appropriate standards where provisions have been
taken in order to ensure that, even in the case of an internal fault, the voltage at the outgoing
terminals cannot exceed the values specified in 414.1.1.
716.43 Protection against overcurrent
716.433 Protection against overload current
716.433.1 Coordination between conductors and overload protective devices
716.433.1.101 Protection against overcurrent
Limitation of current in accordance with IEC 62368-3:2017, 5.3.1 is recognized as a suitable
means of protecting against overcurrent.
716.52 Selection and erection of electrical equipment – Wiring systems
716.521 Types of wiring system
716.521.101
Information technology cables used for the distribution of DC power shall comply with
Category 5, Category 6, Category 6 , Category 7, Category 7 , Category 8.1 or Category 8.2
A A

716.523 Current-carrying capacities
716.523.1.101
ISO/IEC 11801-1 specifies the minimum DC current carrying capacity in any conductor
temperature up to 60 °C. Cables listed in 716.521.101 fulfil at least this operating temperature.
NOTE 1 Any temperature rise of the data cables due to the load current they carry, or other causes, will increase
the attenuation and insertion loss of the installed cabling. Thus the performance of information transmission channels
can be degraded.
NOTE 2 Guidance on the effect of the number of loaded conductors, in a multi-cable bundle, on the temperature
rise of the cables is given in ISO/IEC TS 29125 and requirements and recommendations in relation to planning and
installation of such cable bundles are provided in ISO/IEC 14763-2.
716.523.2.101
The load current (design current) in any conductor shall not exceed 750 mA.
716.526 Electrical connections
716.526.101
The connecting hardware used for data cables used to distribute DC power shall comply with
ISO/IEC 11801-1 and support a continuous operating current of 750 mA per contact.
Where connected equipment can be separated under load, the connecting hardware shall meet
the requirements of the endurance test specified in IEC 60512-9-3 at the appropriate
disconnection load. Also the anticipated number of separations in operation shall not exceed
the value specified in the endurance test for the disconnection load.
NOTE Testing of the mating and de-mating of connectors at currents below this maximum value can be found in
IEC 60512-9-3, IEC 60512-99-001 and IEC 60512-99-002.
