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://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.
