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 enclosures. 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.
