| Mechanical tests | Mechanical strength Result: Test passed Attachment on the carrier DIN rail/fixing support: NS35/NS15 Test force setpoint: 1 N Result: Test passed Note: 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. 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.
