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 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 can 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
