Note
In this circuit type, the motor start may be delayed by up to 5 s in relation to the start command due to the internal run times of the soft starter. Coasting down is the only
possible run-down mode.
Notice
After switching off the control supply voltage and before restarting, the device must be allowed to cool down for at least 30 s, because this has an influence on the
effectiveness of the inherent protection of the soft starter.
This circuit type is not recommended for higher switching frequencies, since the integrated fan cannot idle after the
soft starter has been switched off which means that the switching frequency specified in the technical data will be reduced.
