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, when necessary, we use notes to make you aware of safety considerations.Allen-Bradley, Rockwell Software, Rockwell Automation, RSLinx, Logix5000, RSLogix 5000, RSNetWorx for ControlNet, RSNetWorx for DeviceNet, RSNetWorx for EtherNet/IP, ControlLogix, GuardLogix, CompactLogix, SoftLogix, FlexLogix, PowerFlex 700S, DriveLogix, FactoryTalk, FactoryTalk Administration Console, FactoryTalk Alarms and Events, FactoryTalk Live Data, FactoryTalk View, FactoryTalk View Studio, Kinetix 6000, RSView32, Synchlink, PLC-5, SLC, SLC 500, RSBizWare Batch, ControlFlash, Ultra 3000, PanelView, PanelView Plus, and TechConnect are trademarks of Rockwell Automation, Inc.Trademarks not belonging to Rockwell Automation are property of their respective companies.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.
