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
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
•
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.
