ATTENTION: Personnel responsible for the application of safety-related programmable electronic systems (PES) shall be
aware of the safety requirements in the application of the system and shall be trained in using the system.
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 60664-1), at altitudes up to 2000 m (6562 ft) without derating.
This equipment is not intended for use in residential environments and may not provide adequate protection to radio
communication services in such environments.
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 or be approved for the application 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.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1
, for additional
installation requirements
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided by enclosure
