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
EN/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 for indoor use. 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 more
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see the following:

1770-4.1
, for more installation requirements.
•
NEMA Standard 250 and EN/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.
