1) For permissible main and control voltage values, refer to Technical Data, pages 10-12 to 10-16.
2) Caution: risk of restart!
The start command (e.g. via PLC) must be reset when a group fault occurs, since an automatic restart is
executed when a start command is pending after the reset command is issued. This particularly applies to
motor protection tripping.
For safety reasons, we recommend integrating the group error output (terminals 95 and 96) into the control.
