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.
