E3 and E3 Plus Solid-State Overload Relay User …

1 User Manual E3 & E3 plus Solid-State Overload Relay Catalog Numbers 193/592-EC1, -EC2, -EC3, -EC5. 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 available from your local Rockwell Automation sales office or online at ) describes some important differences between Solid-State equipment and hard-wired electromechanical devices.

2 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.

3 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.
