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 for indoor use. 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 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 more installation requirements.
• NEMA Standard 250 and EN/IEC 60529, as applicable, for explanations of the
degrees of protection provided by enclosures.
