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.
