58 System Installation Recommendations
System Overview
Refer to the following sections when planning your system layout.
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 (6561.7 ft) without derating.
This equipment is considered Group I, 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 the
Allen-Bradley Industrial Automation Wiring and Grounding
Guidelines, publication 1770-4.1, for additional installation
requirements pertaining to this equipment.
