Environment and Enclosure
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 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.
