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 m (6561 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 5V A,
V2, V1, V0 (or equivalent) if nonmetallic. 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.
Besides this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-4.1, for additional installation requirements.
• NEMA Standards publication 250 and IEC publication 60529, as applicable,
for explanations of the degrees of protection provided by different types of
enclosure.
