Safety Considerations Safety considerations are an important element of proper system installation.
Actively thinking about the safety of yourself and others, as well as the condition
of your equipment, is of primary importance. We recommend reviewing the
following safety considerations.
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, Rockwell Automation
publication 1770-4.1 , for additional installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of the degrees
of protection provided by different types of enclosure.
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.
