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.

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.
