Important User Information
Solid state equipment has operational characteristics differing from those of
electromechanical equipment. Safety Guidelines for the Application, Installation
and Maintenance of Solid State Controls (Publication
SGI-1.1 available from your
local Rockwell Automation sales office or online at
http://www.rockwellautomation.com/literature/ ) describes some important
differences between solid state equipment and hard-wired electromechanical
devices. Because of this difference, and also because of the wide variety of uses for
solid state equipment, all persons responsible for applying this equipment must
satisfy themselves that each intended application of this equipment is acceptable.
In no event will Rockwell Automation, Inc. be responsible or liable for indirect or
consequential damages resulting from the use or application of this equipment.
The examples and diagrams in this manual are included solely for illustrative
purposes. Because of the many variables and requirements associated with any
particular installation, Rockwell Automation, Inc. cannot assume responsibility or
liability for actual use based on the examples and diagrams.
No patent liability is assumed by Rockwell Automation, Inc. with respect to use of
information, circuits, equipment, or software described in this manual.
Reproduction of the contents of this manual, in whole or in part, without written
permission of Rockwell Automation, Inc., is prohibited.
Throughout this manual we use notes to make you aware of safety considerations.
IMPORTANT
Identifies information that is critical for successful application and
understanding of the product.
WARNING
Identifies information about practices or circumstances that can
cause an explosion in a hazardous environment, which may lead to
personal injury or death, property damage, or economic loss.
ATTENTION
Identifies information about practices or circumstances that can
lead to personal injury or death, property damage, or economic
loss. Attentions help you:
• identify a hazard
• avoid a hazard
• recognize the consequence
SHOCK HAZARD Labels may be on or inside the equipment, for example, a drive or
motor, to alert people that dangerous voltage may be present.
BURN HAZARD
Labels may be on or inside the equipment, for example, a drive or
motor, to alert people that surfaces may reach dangerous
temperatures.
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.
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 nonmetallic. 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.
