Environment and Enclosure
ATTENTION
This equipment is intended for use in overvoltage Category II applications (as defined in
IEC publication 60664-1), at altitudes up to 2000 meters (6562 feet) without derating.
This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR
Publication 11. Without appropriate precautions, there may be potential difficulties
ensuring electromagnetic compatibility in other environments due to conducted as well as
radiated disturbance.
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 publication 250 and IEC publication 60529, as applicable, for
explanations of the degrees of protection provided by different types of enclosure.
ATTENTION
Preventing Electrostatic Discharge
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.
