Shown with the spring energy storage mechanism in the
discharged state. The wiring diagram comprises the
basic components and all further equipment options for
the various VD4 types. The scope of equipment possible
within an individual type series is listed in the relevant
switchgear list, and the equipment fitted in each indivi-
dual case can be found in the order documentation. Note:
Shunt releases and blocking magnets are fundamentally
wired with rectifiers (e.g. magnet holder 40 with integrated
rectifiers -V1, -V2, -V3 and -V9).
Rectifiers function as free-wheeling diodes if d.c.-supply.
