4.9.4 Grid Connection after Correction of Error
If a grid fault in the inverter has been corrected, the inverter will only switch on when the grid voltage
meets a set of conditions.
For example, the grid voltage must stay within the set limiting values for grid connection
(e.g., parameter "VCtlOpMinNom") for the duration of the grid monitoring time "GriGrdMonTm".
