A.2.3 Switching with supply voltage (control supply voltage)
Requirements
Because of the intrinsic protection, allow an interval of at least 5 minutes to elapse before
restarting the device if the device is switched on and off in normal operation by means of the
supply voltage (control supply voltage).
If a starting command is pending, a restart will be triggered automatically after the reset.
This particularly applies if the motor protection has tripped. Dangerous states of the system
can result.
Reset the start command (e.g. via the PLC or switch) before performing a reset.
To do this, for example, link the group error output (terminals 95 and 96) into the control.
