Is the circuit diagram OK ?

The LED from the MRD does not light up and does not switch on the inverter.
What is wrong?

Thanks

The connections are incorrect. The EXT IOx is just a potential free contact (an electronic contact but still a contact). You will need to supply power by connecting a 470Ohm resistor to battery+ to limit the current in case of fault then the other end connects to EXT IO3+ and EXT IO3- will connect to +A1 then -A2 will connect to battery negative.
