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 enclosures. 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.
