An installation switch has an insulating housing and a terminal connecting arrangement for clamping a connecting conductor having an annular terminal shoe. In broadest terms, the separation process of the present invention is a process for separating cells from a liquid containing cells. In a second test cycle, the memory content of at least one of the previously activated memory cells is read by synchronously actuating the semiconductor memory using a second signal combination of control signals. Other embodiments are described and claimed. A granular FIFO fill level indicator of the DLL provides input to the phase shifter to adjust the frequency of the PLL accordingly.
