Information:
The terminal blocks are pluggable and can be detached from the
electronics. To do this, loosen the two lateral locking levers of the
terminal block with a small screwdriver. When loosening the locking,
the terminal block is automatically squeezed out. It must snap in place
when re-inserted.
