• Check the inverter' s AC side connections (ref. par.
5 of this guide) and repeat the commissioning
procedure.
• Check that the grid voltage, at terminal block
heads, is within the range (width and frequency)
permitted for the inverter' s operation and repeat
the commissioning procedure.
• If this error is frequently repeated, consult the
