It most likely means the inverter itself is not powered using the 2-pole connector next to the 32-pin connector.

Hi John,
Thank You for the advice.
The controller is coneccted to battery stack of 110V. Is there a chance that the controller is damaged and could not connect ?

Supplying high voltage does not supply the inverter gate drive circuitry! Please read: https://openinverter.org/wiki/Toyota_Prius_Gen2_Board

Dear Johu,

I appologise first for the wrong adressing You as JOHN .
Thank You for the enclosure of the controllerfoto .It was a big help indeed.
You are completly correct with the power attachment
.I have tapped the wrong connections,namely the DC-DC input. I was misled by the connector,supposing this to be the right power connection input.
Hope now that evrything will run much better .
Thanks again.
Greetings
