Environmental Considerations
If the product will be subjected to atmospheric contaminants such as moisture, oils,
conductive dust, chemical contaminants and metallic particles, you must mount it vertically
in a metal NEMA type 12 enclosure.
If the ambient temperature inside the enclosure will exceed 40° C (104° F), you must consider
forced air cooling.
Note
It is necessary to maintain the drive surround air ambient temperature at 40° C (104° F)
[50°C (122ºF) with derating of 3% per degree above 40° C].
The amount of cooling depends on the size of the enclosure, the thermal transfer of the
enclosure to the ambient air and the amount of power being dissipated inside the enclosure.
Consult your enclosure manufacturer for assistance with determining cooling requirements.
