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 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 11. Without appropriate precautions, there may be
difficulties with electromagnetic compatibility in residential and other
environments due to conducted and 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 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:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1, for more installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the
degrees of protection provided by different types of enclosure.

Preventing Electrostatic Discharge

ATTENTION: This equipment is sensitive to electrostatic discharge, which
can cause internal damage and affect normal operation. Follow these
guidelines when you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
Do not touch circuit components inside the equipment.
•
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in use.
