Allen-Bradley Bulletin 5370 CVIM User manual

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)
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 the Allen-Bradley Company 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, the Allen-Bradley Company cannot assume
responsibility or liability for actual use based on the examples and diagrams.
No patent liability is assumed by Allen-Bradley Company 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 the Allen-Bradley Company is prohibited.
