Note
Depending on the application case and mechanical load, other arrangements of the mounting accessory can also be chosen.
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.
The IEC 60947-7-1 standard applies for the use of mounting accessories.
The maximum load current of a single clamping unit must not be exceeded.
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.
