HOW TO USE THE IPB

..
'I

GENERAL
This IPB is compiled 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 referenc:e 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 callouts 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
colum,n 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.
