Introduction
This chapter contains various diagrams for use in troubleshooting and maintaining the Agilent power supplies. Separate
diagrams and/or tables are provided to show model differences. For wiring connections to external equipment, refer to the
Operating Manual.
Interconnections
Figure 6-1 is the overall interconnection diagram. The location of each circuit board in the supply chassis is given in
Chapter 3, Figure 3-1.
AC Input and Transformer Connections
Figure 6-2 shows the AC power distribution and Figure 6-9 shows the transformer connectors and cable connections for the
500 watt models (655xA & 665xA).
Circuit Board Schematics
Table 6-1 describes the signal name abbreviations that appear on the schematics. Each schematic has grid coordinates to
help you locate signal origins and destinations. Circuit names and test points are also given. A list of the schematic and
assembly drawings in this chapter are listed under "Figures" in the front matter to this manual. Table 6-2 gives general notes
that apply to the schematic diagrams. Test point information is summarized in Table 6-3.
Component Location Diagrams
Diagrams showing the location of components and test points on each circuit board are shown on the page opposite the
associated schematic(s). The Al Main Board’s component location diagram has grid coordinates and a table to help you
locate components.
