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 61969-2 has been prepared by subcommittee 48D: Mechanical
structures for electronic equipment, of IEC technical committee 48: Electromechanical
components and mechanical structures for electronic equipment.
This second edition cancels and replaces the first edition issued in 2000. It constitutes a
technical revision.
The main technical changes with regard to the previous edition are as follows:
It was the intention when IEC 61969-2 Ed. 1.0 was created that a sectional standard is to be
followed by a detail standard, consisting of IEC 61969-2-1 and IEC 61969-2-2.
The intention of detail standards was to create a recommended but cost-effective range of
outdoor enclosure solutions offered from multiple vendors. However, it became evident that

– 4 – 61969-2 © IEC:2011
the outdoor enclosure applications were extremely application specific and the intended effect
became irrelevant.
Consequently, IEC 61969-2-1 and IEC 61969-2-2 became obsolete and will be withdrawn at
the time when IEC 61969-2 Ed.2.0 is published.
To provide for a useful outdoor enclosure installation matrix IEC 61969-2 Ed. 2.0 focuses on
overall outdoor enclosure co-ordination dimension only.
The text of this standard is based on the following documents:
FDIS Report on voting
48D/482/FDIS 48D/496/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
A list of all parts of IEC 61969 series, under the general title Mechanical structures for
electronic equipment – Outdoor enclosures, can be found on the IEC website.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

Part 2: Coordination dimensions

1 Scope
This part of IEC 61969 applies to the design of enclosures for outdoor applications for
stationary use at non-weatherprotected locations as defined in IEC 61969-1 Ed.2.0.
The internal and external coordination dimensions are derived from IEC 60917-2. The internal
dimensions meet the mounting dimensions of subracks in accordance with IEC 60917-2-2 and
IEC 60297-3. The external dimensions, compared to IEC 60917-2, are partly increased in
order to meet the design requirements of the outdoor specific conditions.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 60917-2, Modular order for the development of mechanical structures for electronic
equipment practices – Part 2: Sectional specification – Interface co-ordination dimensions for

the 25 mm equipment practice
3 Arrangement overview
An example of an outdoor enclosure is given in Figure 1. Application specific roofs and/or
bases/plinth, cable entry/exit and external mounted cable entry or cable management boxes
are not covered by this standard.
