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 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 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.
