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 60664-1), at altitudes up to 2000 m

(6562 ft) without derating.

This equipment is considered Group 1, Class A industrial equipment

according to IEC/CISPR 11. Without appropriate precautions, there

may be difficulties with electromagnetic compatibility in residential

and other environments due to conducted and radiated disturbances.

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.

In addition to this publication, see the following:

• Industrial Automation Wiring and Grounding Guidelines,

publication 1770-4.1

, for additional installation requirements

• NEMA Standard 250 and IEC 60529, as applicable, for explanations

of the degrees of protection provided by enclosures.
