			The CLK and ITE signals comes alive when supplying12V to IG and >40V to the main DC Power supply inlet and pull-up/pull-down connected to them(CLK and ITE). For the inverter to start you need higher voltage >200V to main DC Power supply inlet, STB to GND and send appropriate 10 byte messages to the inverter on ETI.
