ATTENTION
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 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.
See NEMA Standards publication 250 and IEC publication 60529, as
applicable, for explanations of the degrees of protection provided by
different types of enclosure. Also, see the appropriate sections in
this publication, as well as Industrial Automation Wiring and
Grounding Guidelines, Allen-Bradley publication 1770-4.1, for
additional installation requirements pertaining to this equipment.
ATTENTION
POINT I/O is grounded through the DIN rail to chassis ground. Use
zinc plated, yellow-chromated steel DIN rail to assure proper
grounding. Using other DIN rail materials (for example, aluminum or
plastic) which can corrode, oxidize, or are poor conductors can result
in improper or intermittent platform grounding.
