Notes
￫
The block diagrams in Figures 4 and 5 serve merely to represent
the general functions.
The actual wiring depends on the application case
(
chapter 5, “Application examples”, page 33).
￫
The voltages supplying the motor starter on terminals A1 and
A2 and the voltage which activates terminals ON or R and L do
not need to originate from the same source.
Reference point for activation is terminal E.
