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
ble from your
local Rockwell Automation sales office or online at
escribes 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

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:

Rockwell Automation publication
additional
installation requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for
explanations of the degrees of protection provided by different 
types of enclosure.
