Electrical Information
Sign Parts Catalog Overview
Sign parts catalogs include replacement part information with indexed figures/illustrations and parts list
tables. A guide to the various signs and their respective publication numbers appears in Table J on Page
53. Whenever possible, only order parts by referencing their respective part numbers. Also included in the
table are enclosure and display dimensions including width (W) and height (H) measurements given in
inches. The numbers of pixels specified in the table are for horizontal pixels.
NOTE: Again referring to Table J
, a sign’s part number is the same as its respective Parts Catalog
Publication Number.
Electrical/Cable Harness Information Overview
Standard sign system and cables are identified in the pages that follow. The illustrations of those figures
also include detailed information about their connectors and pin-out locations.
NOTE: The cable/connector types and sizes may vary depending on each bus type
installation/application.
Although an overall schematic and a general wiring diagram have been included, in order to make the
information easier to read and interpret, the user will note that these illustrations have been divided into
quadrants or simply divided in half. Each quadrant or half has then been enlarged in the ―detail‖ figures
that follow the overall view.
NOTE:
To easily locate a cable harness or wiring diagram, refer to this manual’s List of Figures and
List of Tables that follows the manual’s Table of Contents located at the beginning of this manual.
Also refer to Table K on Page 54.
