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 (6562 feet) 
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 enclosure must have suitable 
flame-retardant properties to prevent or minimize the spread of flame, 
complying with a flame spread rating of 5VA, V2, V1, V0 (or 
equivalent) if non-metallic. 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.
Besides this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, for
additional installation requirements, Allen-Bradley publication 
1770-4.1.
• NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided 
by different types of enclosure.
