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 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
T
his 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.
