Environment and Enclosure
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 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
1770-4.1 .
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.
ATTENTION
Personnel responsible for the application of safety-related Programmable
Electronic Systems (PES) shall be aware of the safety requirements in the
application of the system and shall be trained in using the system.
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.
