You can activate internal ground-fault monitoring by parameterization. It covers two different
operating conditions:
● Normal operation up to 2 x I
current setting I
● Start-up or overload operation to 2 x I
current setting I
detected.
Trip level activity, warning level
Unless deactivated, this function is always active, independent of whether the motor is
running or not (operating state "ON").
