Environment and Enclosure
Prevent Electrostatic Discharge
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial environment, 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 "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 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.
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.
