Description
The soft starter detects the type of connection (inline circuit or
inside-delta circuit) automatically if the load voltage is applied and
the motor is connected to the device. Thus no parameterization of
the type of connection is necessary.
The connections of the soft starter are wired into the motor feeder
between the motor starter protector and the motor.
The inside-delta circuit makes it possible to increase the operable
motor power of the individual devices by a factor of root 3.
Operation in the inside-delta circuit is not possible for 690 V.
