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

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.
