The connection procedure is simple: remove conductor isolation, insert a screwdriver into the square opening in the terminal block to compress the spring, releasing the access and then insert the conductor into the terminal block. 

When removing the screwdriver, the connection becomes effective. The contact pressure in this connection system is uniform and independent of user/operator, as it is provided by the spring.
