WIRING DIAGRAM

The power source consists of a number of function modules, which are described in the
component descriptions on the following pages. Wire numbers and component names in
the wiring diagrams show to which module each component belongs.
Wires/cables within modules are marked 100 - 6999.
Wires/cables between modules are marked 7000 - 7999.
Components outside modules - e.g. capacitors - are named such as C1 - C99,
connectors XS1 - XS99 (S = socket), XP1 - XP99 (P = plug), XT1 - XT99 (T = terminal).
Circuit boards within each module have names such as 20AP1 - 20AP99.
20 = module association, 1-69
AP = circuit board
1 = individual identification number, 0-99
Transistors within particular modules have identification numbers such as 15Q1 -
15Q99.
15 = module association, 1-69
Q = transistor
1 = individual identification number, 0-99

Component description
