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 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 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.
