Note
For the component design, refer to chapter Technical data [Page 121].
If a main or line contactor is used, it should not be connected between the soft starter and the
motor. The soft starter could otherwise indicate a "Missing load voltage" fault in case of a
start command and delayed connection of the contactor.
