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.
