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.
