• Check if the ground line is connected with the
inverter;
• Make sure the grounding connection of the
inverter is connected and reliable.
If this fault occurs often, contact the service.
• Check the grid voltage at the point of
connection of inverter.
If the grid voltage is outside the permissible
range due to local grid conditions, try to modi-
fy the values of the monitored operational limi-
ts after informing the electric utility company
rst.
If the grid voltage lies within the permitted ran-
ge and this fault still occurs, please call service.
