Start input (terminal 1) on 3RW30 and 3RW402 to 3RW404

Rated control voltage is present at terminal A1 / A2: The startup process of the soft starter
begins when a signal is present at terminal 1 (IN). The starter operates until the signal is
removed again.
If a ramp-down time is parameterized (3RW40 only), a soft stop starts as soon as the signal
is removed.
The potential of the signal at terminal 1 must correspond to the potential of the rated control
voltage at terminal A1 / A2.
For recommended circuits, e.g. control by means of pushbuttons, contactor contacts, or a
PLC, refer to chapter Typical circuit diagrams (Page 161).
