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 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR 11. Without
appropriate precautions, there may be difficulties with electromagnetic compatibility in residential and
other environments due to conducted and radiated disturbances.
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 enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of flame, complying with a flame spread rating
of 5VA, V2, V1, V0 (or equivalent) if nonmetallic. 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 Standard 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided
by enclosures
