Scope

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 Consequently, IEC 61969-2-1 and IEC 61969-2-2 became obsolete and will be withdrawn at the time when IEC 61969-2 Ed.2.0 is published.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