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 Consequently, IEC 61969-2-1 and IEC 61969-2-2 became obsolete and will be withdrawn at the time when IEC 61969-2 Ed.2.0 is published.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. La CEI 61969-2:2011 sapplique a la conception des enveloppes pour des applications exterieures, pour une utilisation a poste fixe dans les lieux exposes aux intemperies tels que definis dans la CEI 61969-1 Ed.2.0. Les dimensions de coordination interieures et exterieures sont tirees de la CEI 60917-2. Les dimensions interieures correspondent aux dimensions de montage des bacs a cartes, selon la CEI 60917-2-2 et la CEI 60297-3. Les dimensions exterieures ont ete partiellement augmentees par rapport a la CEI 60917-2 pour tenir compte des contraintes liees aux conditions specifiques du plein air. Cette deuxieme edition annule et remplace la premiere edition, parue en 2000, dont elle constitue une revision technique. Les principaux changements techniques par rapport a ledition precedente sont les suivants: Lors de lelaboration de la CEI 61969-2 Ed. 1.0 lobjectif etait quune norme intermediaire soit suivie dune norme particuliere, constituee par la CEI 61969-2-1 et la CEI 61969-2-2. Lobjet des normes particulieres etait de creer une gamme recommandee mais rentable de solutions denveloppes de plein air proposees par de nombreux fournisseurs. Toutefois, il est devenu evident que les utilisations des enveloppes de plein air etaient dapplication tres specifique et leffet vise devenu non pertinent. En consequence, la CEI 61969-2-1 et la CEI 61969-2-2 etant devenues obsoletes, elles seront supprimees au moment de la publication de la CEI 61969-2 Ed.2.0. En vue de prevoir une matrice dinstallation des enveloppes de plein air utile, la CEI 61969-2 Ed. 2.0 porte uniquement sur les dimensions hors-tout de coordination des enveloppes de plein air.
