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 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 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 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.
