Solid state equipment has operational characteristics differing from those
of electromechanical equipment. “Safety Guidelines for the Application,
Installation and Maintenance of Solid State Controls” (Allen-Bradley
Publication SGI-1.1) 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.
