Environment and Enclosure

ATTENTION

This equipment is intended for use 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 "enclosed" equipment. It

should not require additional system enclosure when used

in locations consistent with the enclosure type ratings

stated in the Specifications section of this publication.

Subsequent sections of this publication may contain

additional information regarding specific enclosure type

ratings, beyond what this product provides, that are

required to comply with certain product safety

certifications.

NOTE: 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.
