ATTENTION
Environment and Enclosure
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 1770-4.1.
NEMA Standards 250 and IEC 60529, as applicable, for explanations of the degrees of protection provided
by different types of enclosure.
ATTENTION
Prevent 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.
•Use a static-safe workstation, if available.
•Store the equipment in appropriate static-safe packaging when not in use.
WARNING
The optional 17xx-xxx accessories are not certified for use in hazardous location applications.
Use these optional accessories only in nonhazardous location applications.
