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.
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.
