Im installing VE.Bus BMS V2, I have a multiplus 3000. I belief the 3000 requires a Mains Detector. The installation instructions is not very clear, is there a specific installation manual for the mains detector? It has 2 output (blue/brown) cables, the BMS instructions only show 1 cable. What happens with the second cable?
IMO the manual is pretty clear for what devices the mains detector is needed:

The mains detector is not required for the new style MultiPlus 12/1600/70 and MultiPlus 12/2000/80, MultiPlus-II, Quattro-II and inverter models. In this case, these chapters can be skipped, and the mains detector should be disposed of.
Do you have one of the mentioned devices?
Yes? → don’t use it
No? → use it
And for the 2nd cable:
In the case of a MultiPlus, only use one AC wire pair, and in the case of a Quattro, use both wire pairs.
The 2nd cable is for the 2nd AC input of a Quattro.
