Question:
Which limits are applicable in the examples showed in figures?
Decision:
For case 1, a limit of 85 K applies to the whole enclosure, because the grid covers a substantial part of the enclosure. If the area A of the photograph is of continuous metal construction, area B may be considered as an air outlet (limit 130 K).
For case 2, the limit of 130 K shall apply to the upper air outlet. The others air outlets (C and D) shall comply with 85 K limit.
For case 3, the whole enclosure shall comply with 85K.
