Environment and Enclosure
Prevent Electrostatic Discharge
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 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, publication
, for additional
installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees of
protection provided by enclosures.
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.
