Hi,
Normally with 2 lines i would use 3 PSU’s and 2 TP couplers and add the Wiser in main line with 1 160ma PSU and the 2 couplers, behind both couplers a 640ma PSU and your KNX devices divided over the 2 lines.
If you are sure that there never will be more then 2 lines it could also be done with 2x 640ma PSU and one TP coupler between the 2 lines and add the Wiser for KNX in one of the lines. However this is not the methode how KNX tells you to do it but works fine. If you ever need to add a extra line you need to change everything to setup above.

Erwin
