DC-DC Charger adding an isolation relay

[Guzziando]

I am installing a B2B charger in a V-Line autotrail. I believe that I need to install an isolation relay, but wondering which wires I need to cut. There are 2 green and brown wires that come from the battery on the VBOUT connector, are these the wires?

Yes they are the ones

It's nice to see that Sargent have supplied instructions for this particular setup.

Yes they are the ones

Thank you, do I need to cut both wires?

Yes, they are both doing the same job and joined together at each end.

Just as a FYI, I have made this modification to my Kon-Tiki (well a variation of it as I don't have the Green PCB on the right of your picture), now, every time I start the engine and the relay activates as it should the Sargent tracker detects a disconnect of the leisure battery and sends an alert, so within a mile of setting off I have the control centre on the phone. I will get it sorted, but it'll have to wait until I return from my current break.

It might also be worth noting that I've fitted a Victron B2B, not the Sargent on shown in the diagram.

I also fitted a Vctron, but was using the picture as guidance.
