1) For permissible main and control voltage values, refer to Technical Data,
Pages 10-8 to 10-12.
2) Caution: risk of restart!
The start command (e.g. by the PLC) must be reset before a reset
command is issued, as 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 general fault output
(terminals 95 and 96) into the control.
