Environment and Enclosure
This equipment is intended for use in a Pollution
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
Publication 11. Without appropriate precautions,
there 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.
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 1770-4.1 ("Industrial
Automation Wiring and Grounding Guidelines"),
for additional installation requirements pertaining
to this equipment.
