Not sure about the blue/white and pink wires, but the 3 non-insulated wires are earth/ground (one for each bundle of wires within the cable) and are supposed to be connected together.

The cable structure can be found in the

Thanks for the replies.

Did have a flick through the handbook but couldn't see why the two wires would be connected.

Though all works so no problem really

As far as I'm aware, ML-sense (blue-white) isn't actually used.

Blue abd Pink should be connected when done in this manner.  However if you ahve any real concerns (but you shouldn't) just use a masterlink junction box to make the connectioin.

when a run of masterlink cables reaches 20m it is nessasery to connect the pink to step the voltage up to maintain  correct operation. this is done inside a masterlink junction box. this is also the reason why it is not possible to purchase a 'pre made' masterlink cable woth plugs at each end that is longer than 20m.

Makes sense, the cables run to the other rooms and probably reach the 20m mark.

Due to moving the beoport i will need to create a new junction half way along one the longer wires - as this is probably only 5-8m further along do i need to step the voltage again at the new junction?

Thanks
