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 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.
Besides this publication, see:
• Industrial Automation Wiring and Grounding
Guidelines, Allen-Bradley publication 1770-4.1, for 
additional installation requirements. 
• NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees 
of protection provided by different types of 
enclosure.
