Environment and Enclosure
ATTENTION
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.
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 1770-4.1,
Industrial Automation Wiring and Grounding Guidelines, for additional installation
requirements pertaining to this equipment.
