HOW TO USE THE IPB
GENERAL
This IPB is complied following the organization and nomenclature of
the engineering drawing structure.
MAJOR ASSEMBLY LOCATOR
The Major Assembly Locator (first illustration) is an index that
provides a description and a figure reference for all illustrations used in
this manual.
INDENTED PARTS LIST
This manual identifies each assembly being broken down (figure
reference callout), and all parts of that assembly. Further breakdown
of an assembly is shown by an asterisk ( •) preceding the item call outs
in the Description Column. The number of asterisks preceding an item
is used to denote the subordination of that item with respect to the
Major Assembly. A single asterisk preceding an item description
indicates that the item is part of the major assembly being illustrated.
Items that are subordinate to single asterisks items, are denoted by
two asterisks ( • •) and immediately follow the related single asterisk
item. Additional asterisks are used, as required, to denote further
subordination. This system of part identification, provides a means for
the user to identify the next higher assembly item and make alternate
selections for parts when the required replacement part or assembly is
not immediately available.
COLUMN CALLOUT DESCRIPTION
Figure & Item - Indicates the figure number and item number of each
part.

ECO Cut-In - The notation at the top of this column indicates the
ECO level of the system (option), at which the IPB was initially
prepared. Subsequent ECO level designations, that modify existing
parts or add new parts to the device, are Inserted in the ECO Cut-In
column next to the part that is added or modified. A bracket ( [)
preceding the item description Is used to indicate the parts affected by
ECO's.
Vendor Code/Part No. - Indicates vendor parts that are not stocked
by DEC. Refer to the Field Service Spares Catalog (vendor part
number to DEC part number) for the vendor code cross-reference.
Used On Code - Letters In this column correspond to the variation
codes assigned in Figure 1. Parts with an Alpha notation(s) are used
only in those option variations. A blank indicates that the part Is used
on all option variations.
Ref Fig No. - A cross reference between illustrations. For each Major
Assembly, the number in this column denotes the figure of the next
higher assembly. For all subassemblies, the number in this column
denotes the figure showing additional detailed breakdown.
SYMBOL USAGE
Hardware Designators - Alpha designators for screws (S), washers
(W), nuts (N), and retaining rings (R) are inserted after the item
number callouts on the illustration when stacked item numbers are
used.
Attaching Hardware - The @ symbol is inserted before any part that
is used as attaching hardware. Attaching hardware is denoted as those
parts that are not an integral part of the referenced assembly.

Description - Lists the name of the part and pertinent specifications
(when required). Asterisks preceding the description denote the
subordination of the part to the next higher assembly.

(NFR) Not Field Repairable - The (NFR) symbol is inserted after
any assembly that is not to be field dismantled.

DEC Part No. - Lists the DEC part ordering number. A blank in this
column indicates a DEC part number was not assigned at the time of.
publication.

Other Symbols - Any other symbols that are required for kits,
accessories, etc., will be explained and appear as part of the item
description.
