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.literature.rockwellautomation.com, 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.
