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. 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, V2, V1, V0 (or
equivalent) 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:
•
Industrial Automation Wiring and Grounding Guidelines, for
additional installation requirements, Allen-Bradley publication
.
•
NEMA Standards 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different
types of enclosure.
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.
WARNING:
When you connect or disconnect the removable
terminal block (RTB) with field-side power applied, an electrical arc
can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
