How to use the parts lists and diagrams
The figures in this chapter show the major subassemblies in the product and their component parts. A
parts list table follows each exploded view assembly diagram. Each table lists the item number, the
associated part number, and the description of each part. If a part is not listed in the table, then it is
not a field replacement unit (FRU).
CAUTION: Be sure to order the correct part. When looking for part numbers for electrical
components, pay careful attention to the voltage that is listed in the description column. Doing so will
ensure that the part number selected is for the correct product model.
NOTE: In this manual, the abbreviation “PCA” stands for “printed circuit-board assembly.”
Components described as a PCA might consist of a single circuit board or a circuit board plus other
parts, such as cables and sensors.
