This provides manufacturers and
32、users of generic outdoor enclosure solutions with minimum performance compliance criteria; thermal solutions pending on the environment an outdoor enclosure is subjected to. Since forced air heat dissipation and acoustic noise are closely related, noise limitations are typically defined by local reg
33、ulatory limitations. Typically, it becomes the responsibility of the outdoor enclosure vendor to provide a solution for thermal management within the local regulatory noise limitations.

34、vironmental requirements, tests and safety aspects 1 Scope This part of IEC 61969 specifies a set of basic environmental requirements and tests, as well as safety aspects for outdoor enclosures under conditions of non-weatherprotected locations above ground. The purpose of this standard is to define
35、 a minimum level of environmental performance in order to meet requirements of storage, transport and final installation. It is the intention to establish basic environmental performance criteria for outdoor enclosure compliance. 2 Normative references The following referenced documents are indispen
