Hello, I struggle to find how exactly to wire the Quattro 12/3000 to the smart BMS 12/100 to allow the BMS to turn off charging. I have the Load Disconnect on the BMS wired to my Smart Battery Protect (for my 12 volt system) and I believe I have to connect the “charge disconnect” on the BMS via this cable (inverting remote on/off ASS030550120) to the quattro. But I can’t find any documentation which port on the quattro I should use to connect the two cables on the charger side of the inverting remote on off cable. Thank you so much for your help!
There is a chapter and a link to a document in the manual:
You need two ASS030550120 for the Quattro to stop charging and discharging.
Thank you so much, Matthias. Now I just need to find a way to run the assistant on my macbook and probably buy this MK3‑USB interface cable… or is there any other way to set the Aux port to do charge disconnect? As for the second cable, I have connected the load disconnect from the BMS to the smart Battery protect, so It’s not available anymore. is that a problem? thanks again!
You can connect more than one wire to the load disconnect 
Oh, That’s clever ! 
and makes sens ahah:) Thank you so much!
