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
publication 60664-1), at altitudes up to 2000 meters
without derating.
This equipment is considered Group 1, Class A
industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions,
there may be potential difficulties ensuring
electromagnetic compatibility in other environments
due to conducted as well as radiated disturbance.
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 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.
See NEMA Standards publication 250 and IEC
publication 60529, as applicable, for explanations of
the degrees of protection provided by different
types of enclosure. Also, see the appropriate
sections in this publication, as well as the
Allen-Bradley publication 1770-4.1 (“Industrial
Automation Wiring and Grounding Guidelines”), for
additional installation requirements pertaining to
this equipment.
