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.
• Besides this publication, see:
– Industrial Automation Wiring and Grounding Guidelines,
Allen-Bradley publication 1770-4.1, for additional
installation requirements.
– NEMA Standards publication 250 and IEC publication
60529, as applicable, for explanations of the degrees of
protection provided by different types of enclosure.
ATTENTION
This equipment is sensitive to electrostatic discharge that 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 wrist strap.
• 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.
