Segment terminals can only be used in the 24 V DC area. Segment terminals can be used
to create partial circuits (segment circuits) within the main circuit.
On segment terminals without a fuse, the connection between the main circuit U
segment circuit U
a fuse establish this connection automatically.

terminal.
The segment terminal interrupts the segment circuit U
previous terminal.
For more detailed information about the supply voltages, please refer to "Circuits and
provision of supply voltages" on page 7-1.
The maximum current carrying capacity of the jumper contacts on the side is specified in
"Current and voltage distribution" on page 7-12.
The terminal is connected to functional earth ground when it is snapped onto the grounded
DIN rail via the FE spring on the bottom of the terminal. This spring is connected to the FE
potential jumper and to the terminal points for an FE connection.
When snapped onto the previous terminal, the segment terminal is connected to the FE
potential jumper of the station.
For more detailed information about the function, properties, and wiring of the individual
terminals, please refer to the terminal-specific documentation.
