Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC publication
60664-1), at altitudes up to 2000 meters without
derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR

may be potential difficulties ensuring electromagnetic
compatibility in other environments due to conducted
as well as radiated disturbance.
This equipment is supplied as "enclosed" equipment. It
should not require additional system enclosure when
used in locations consistent with the enclosure type
ratings stated in the Specifications section of this
publication. Subsequent sections of this publication
may contain additional information regarding specific
enclosure type ratings, beyond what this product
provides, that are required to comply with certain
product safety certifications.
NOTE: See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations of the
degrees of protection provided by different types of
enclosure. Also, see the appropriate sections in this
publication, as well as the Allen-Bradley publication
