4.3 Electrical diagrams.
4.3.1 Wiring coding system.
The main circuits are not shown in the wiring diagrams
due to clarity. The control circuit is presented as a typical
circuit diagram and is a combination of numbered basic
diagrams for drives, trips and indicators.
Using the key numbers of the basic plan, you can derive
the number of the complete diagram.

1) These relays are part of internal emergency STOP circuit. It
is a 24VDC closed circuit, through all the control units in the
box. Serial connection of all emergency relays is realized
through connections ( :5/:6) in every PCB’s terminal. In case
of control voltage lost or unit’s damage, circuit is locking
possibility to switch ON the breaker.
