Note
With a combination of connection blocks and interlinking
blocks with metal on plastic or plastic on metal, always use
the appropriate screws for the interlinking block (see

1.1.3 The power supply concept of the CPX terminal
The operating and load voltages for the CPX terminal are sup
plied via the interlinking blocks (see Tab.1/5 and Tab.1/6).
These conduct the operating and load voltages to the neigh
bouring modules.
Interlinking blocks are available in various housing designs
and with alternative connections:
