A terminal block arrangement includes a housing and a plurality of connection terminals, each connection terminal including at least one terminal unit for contacting at least one conductor, which can be received on the connection terminal, and at least one associated actuation unit for actuating the terminal unit in order to selectively transfer the terminal unit between at least two positions. More specifically, a way of measuring a set of previously-operated blades to determine their post-operation geometric characteristics is provided where an offset due to deformation of the hardface surfaces of the shroud is determined. And the partition plates 16 construct a second reinforcement part 31 having an approximately rectangular cross sectional shape of a width capable of supporting an outer edge of a head part 51 of a nail 50 at a portion 52 where a columnar reinforcement body 40 for supporting a form is to be nailed. A radio access network is coupled to the IP core network and the cellular telephone. The second processor module includes a second microprocessor and generates the processed data based on data from the sensors.
