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 not intended for use in residential environments and may not provide adequate protection to radio
communication services in such environments.
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 or be approved for the application if nonmetallic. 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
, for additional installation requirements.
• NEMA 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures.
