ATTENTION
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.
