NoteWhen aligning several blocks, it is recommended to either place a DIN rail adapter underneath the connection point or a flange element between the blocks.
For versions with 6 or 7 connections, it is enough to place one DIN rail adapter centrally per block and place flange elements after every other block.
When using the DIN rail adapter PTFIX-NS35, an aligned block must not protrude by more than a half.
