Notes on operation
the blocks can be bridged with one another via the conductor shaft, for corresponding plug-in bridges, see accessories
Note
For power distribution applications, IEC 60364-4-43.2008; modified + corrigendum Okt. 2008 (DIN VDE 0100-430:2010-10) section 433.2 ff must be observed!
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 aligning several blocks, it is recommended to either place a DIN rail adapter underneath the connection point or a flange element between the blocks.
When using the DIN rail adapter PTFIX-NS35, an aligned block must not protrude by more than a half.
