Environment and Enclosure
Preventing 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 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 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
.
• NEMA Standards 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.
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.
