Note
Specific designations of the process terminals in the wiring and block diagrams of the I/O
modules / terminal blocks
● RES: Reserved, these process terminals must be left unconnected for future expansions
● n.c.: Not connected, these process terminals have no function. However, they can be
connected to potentials specifically defined for a module, for example, for the laying unused
wires.
Supply voltage
Connect the supply voltage to a light-colored terminal block. The following two tables show the
terminal blocks to which you need to connect the cables of the supply voltage.
