ATTENTION
Environment and Enclosure
This equipment is intended for use in overvoltage Category II
applications (as defined in IEC publication 60664-1), at altitudes up to
2000 meters 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 "enclosed" equipment. It should not
require additional system enclosure when used in locations
consistent with the enclosure type ratings stated in the Specifications
section of this publication. Subsequent sections of this publication
may contain additional information regarding specific enclosure type
ratings, beyond what this product provides, that are required to
comply with certain product safety certifications.
NOTE: See NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of protection
provided by different types of enclosure. Also, see the appropriate
sections in this publication, as well as the Allen-Bradley publication
1770-4.1 ("Industrial Automation Wiring and Grounding Guidelines"),
for additional installation requirements pertaining to this equipment.
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.
• If available, use a static-safe workstation.
• When not in use, store the equipment in appropriate static-safe
packaging.
