Foreword This Rockwell Automation publication is formatted to harmonize with
NEMA Standards Publication No. ICS 1.1-1987
, also titled Safety
Guidelines for the Application, Installation and Maintenance of
Solid-State Control. The text of the NEMA Standard has been
reprinted verbatim, with NEMA’s permission, in the left column,
captioned “NEMA Standard Text”. The right column, captioned
“Explanatory Information”, contains Rockwell Automation
comments and explanation. The comments provide supplementary
information to the NEMA Standard to help the reader better
understand the characteristics of industrial equipment employing
solid-state technology. Rockwell Automation is solely responsible for
the explanatory comments, which are not part of the NEMA
Standard.
