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 "open type"
equipment. It must be mounted within an enclosure
that is suitably designed for those specific
environmental conditions that will be present and
appropriately designed to prevent personal injury
resulting from accessibility to live parts. The
interior of the enclosure must be accessible only by
the use of a tool. Subsequent sections of this
publication may contain additional information
regarding specific enclosure type ratings 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.
