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 m (6561 ft) 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.
