ATTENTION: 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 considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11. Without appropriate
precautions, there may be difficulties with electromagnetic compatibility in residential and other environments due to
conducted as well as radiated disturbances.
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 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.
In addition to this publication, see the following:
• Industrial Automation Wiring and Grounding Guidelines, 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
