• “0A-_ _ _ _-_ _ _ _” represents an assembly, such as a circuit board and the
plate or bracket to which it mounts. A collection of circuit boards working
as a single unit may also carry an assembly label.
• “W-_ _ _ _” indicates a wire or cable. Cables may also carry the assembly
numbering format in certain circumstances. This is especially true of ribbon
cables.
• “F-_ _ _ _” signifies a fuse.
Figure 3: Typical Label
Most circuit boards and components within this sign
carry a label that lists the part number of the unit. If
the Replacement Parts List in Section 4.13 does not
list a circuit board or assembly, use the label to order a
replacement.
Figure 3 illustrates a typical label. The
part number is in bold.
