IEC 61969-1:2020 pdf download.Mechanical structures for electrical and electronic equipment – Outdoor enclosures
1 Scope
This part of IEC 61969 contains design guidelines for outdoor enclosures and is applicable over a wide field of mechanical, electromechanical and electronic equipment and its installation where a modular design is used. The objectives of this document are: – to provide an overview of specifications for enclosures focused on requirements for outdoor applications for stationary use at non-weather protected locations, and – to achieve product integrity under outdoor conditions and to ease product selection for the sourcing of outdoor enclosures from different vendors. These enclosures are considered to contain any equipment and provide protection for the outdoor installed facilities against unwanted environmental impacts. The installed equipment can be, but is not limited to, subracks or chassis according to IEC 60917 (all parts) or IEC 60297 (all parts). A typical outdoor enclosure is shown in Figure 1.
