IEC 61696-2:2011适用于在IEC 61969-1 Ed.2.0中定义的非防风雨位置固定使用的户外应用外壳的设计。内部和外部协调尺寸源自IEC 60917-2。内部尺寸符合IEC 60917-2-2和IEC 60297-3规定的机架安装尺寸。与IEC 60917-2相比，外部尺寸部分增加，以满足室外特定条件的设计要求。第二版取消并取代2000年发行的第一版。这是一项技术性修订。与前一版相关的主要技术变化如下:当IEC 61969-2 Ed 1.0创建时，其意图是在一个分标准之后遵循一个由IEC 61969组成的详细标准- 2-1和IEC 61969-2-2。详细标准的目的是创建一系列由多家供应商提供的推荐但经济高效的户外外壳解决方案。然而，很明显，户外外壳的应用非常具体，预期效果变得无关紧要。因此，IEC 61969-2-1和IEC 61969-2-2已过时，并将在IEC 61969-2 Ed.2.0发布时撤销。为了提供有用的户外外壳安装矩阵，IEC 61969-2 Ed.2.0仅关注整体户外外壳协调尺寸。

IEC 61696-2:2011 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. 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 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 Consequently, IEC 61969-2-1 and IEC 61969-2-2 became obsolete and will be withdrawn at the time when IEC 61969-2 Ed.2.0 is published.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.
