When the frequency level is out of the operational levels shown in the table, the
inverter will disconnect from the grid.
Remarks:
(1) The maximum time to disconnect refers to the interval between the
abnormal frequency level and the action of inverter (disconnect from the
grid).
(2) After the low / high frequency, the inverter will only reconnect to the grid
again when the grid frequency returns to normal operation range,
respecting the reconnection waiting time of 300 seconds.
