Table 1 - 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 EN 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 for indoor use. It must be mounted within an enclosure that is suitably designed for those
specific environmental conditions that are 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 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 250 and EN/IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosures.
