ATTENTION: 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.
