Communications power for the bus interface
I/O supply for analog terminals
Ground of communications power and I/O supply for analog terminals
Segment circuit supply
(if necessary with overload protection)
Main circuit supply
(if necessary with overload protection)
Ground of segment and main supply
Functional earth ground
FE contact to the DIN rail
(for bus couplers, segment terminals, and power terminals for the SELV area)
Local bus
Terminal inputs and outputs are supplied with voltage via the segment circuit.
The voltage for the segment circuit can be tapped from the main circuit. In addition, some
terminals tap the voltage directly from the main circuit.

Depending on the terminal function, not all of the jumpers listed in Figure 7-2 are present
on a terminal. Please refer to the circuit diagram of the terminal to see which jumpers are
available for a terminal and how they are internally connected. The circuit diagram is
shown in the terminal-specific data sheet.
