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 Publication 11. Without appropriate
precautions, there may be potential 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.
