Wiring diagrams
The wiring diagrams are assigned to the familiar function groups
a
00-91. The systems are listed alphabetically with an indication of
the function group/ function subgroup in the "Search aid for all
wiring diagram groups"
OV00.01-S-1901VA or A3 (paper version).
The wiring diagrams are filed in the respective function group
a
arranged according to the PE number,
e.g.: PE07.16-S-2000VA
PE07.16-S-2000IVB
To check the completeness of the volume the sequence of the
wiring diagrams filed can be seen from the lists of contents of the
respective function group. For supplements the wiring diagrams
should be filed as per the supplement sheet.

column in the row in front of the connector designation. For
connectors, which are installed as standard, special
equipment specification is noted directly at the respective jack
and/or connector.
The feed of the terminal blocks is shown by means of an
arrow pointing to the left, the outputs by means of arrows
pointing to the right. The grouping of the individual variants/
special equipment (SA) is highlighted by means of broken
lines. All outputs to components, which are installed as
standard, are listed up to the first broken line.
The wiring diagrams are prepared as function diagrams or control
a
unit diagrams and are built up as follows:
-Function diagrams
The control units and electrical components belonging to the
function are shown as symbols. The functional connections are
realized by direct lines or by the data bus.
-Control unit diagrams
Control units are represented complete with all connected
components. The feed of the control units appears first.
The wiring diagrams also contain linkages of possible versions and
functions.
Linkages, recognizable as versions, are framed and provided with
an abbreviated designation/ abbreviation.
The versions are designated with 1
