1) For permissible values for main and control voltage, refer to Technical Data, Pages 10-8 to 10-12.
2) Caution: risk of restart!
The start command (e.g. via PLC) must be reset if a general fault occurs as an automatic restart is executed
when a start command is pending after the reset command is issued. This applies to motor protection
tripping in particular.
For safety reasons, we recommend integrating the general fault output (terminals 95 and 96) into the
control.
