Note
The enclosure size should be determined by considering multiple
factors. This includes the outside ambient temperature, total heat
generated from the installed equipment, sealed or unsealed
enclosure type, enclosure material, paint color, mounting method
(wall, pole, ground, etc.), and sun load. The smaller enclosure size
you choose, the higher risk of overheating the product faces.
If the product overheats in an enclosure that was built without taking
into account these factors, the warranty of the product might be
voided. Consult Allied Telesis when assistance is needed.
