Environment and Enclosure
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 (6562 feet) without derating.
This equipment is considered Group 1, Class A industrial equipment according to
IE
C/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
en
closure 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 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:
•Ind
ustrial Automation Wiring and Grounding Guidelines, publication 1770-4.1, for
additional installation requirements.
•NEMA Standards publication 250 and IEC publication 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure.
