1) For permissible main and control voltage values, refer to Technical Data, pages 9-7 to 9-10.
Caution: risk of restart!
The start command (e.g. by the PLC) must be reset before a reset command, since an automatic restart is
executed when a start command is pending after the reset command. This especially applies to motor
protection tripping.
For safety reasons it is recommended to integrate the group fault output (terminals 95 and 96) into the
control.
