Electrical potential and data routing (Inline)

6452_en_11 Phoenix Contact 89 / 188

GND

(24 V DC area)

This potential jumper is ground for the main and segment circuits.

NOTE: Overload

Please note that the GND potential jumper carries the total current of the main and

segment circuits. The total current of the main and segment circuits must not ex-

ceed the maximum current carrying capacity of the potential jumpers (8 A). The

maximum current carrying capacity is determined not only by the potential jump-

ers, but also by the power/segment terminal used.

Calculate the current in the station. Refer to the data provided in the terminal-spe-

cific data sheets for your particular application.

The Project+ software provides support when calculating the currents (see Section

“Appendix: Software support” on page 176).

(24 V DC area)

The FE potential jumper is connected to the grounded DIN rail via the FE spring at each

bus coupler, each 24 V power terminal, and each segment terminal and is led through all

subsequent 24 V terminals.

In addition, connect the FE connection to a grounding terminal at the bus coupler.

If the FE jumper is interrupted by a 120 V AC/230 V AC voltage level, reconnect the FE

connection to a grounding terminal at the subsequent 24 V DC power terminal.

Please also observe the information in Section “Grounding concept” on page 112.

FE spring

(24 V DC area)

This spring creates the FE contact between the bus coupler, a 24 V DC power terminal or

a segment terminal, and the grounded DIN rail.

Data routing

(all areas)

The bus signal is also transmitted within the station using a connection that is created au-

tomatically when the station devices are snapped on.

Current carrying capacity

(all areas)

The maximum total current flowing through the potential jumpers is limited. The maxi-

mum current carrying capacity for each circuit is specified in Section “Circuits and provi-

sion of supply voltages” on page 80.

Please also observe the information about the current carrying capacity of the pow-

er and segment terminals provided in the terminal-specific data sheets.

NOTE: Malfunctions

If the current carrying capacity of the potential jumpers U

or U

ANA

is reached, the

voltage must be boosted via a power terminal, or a new station must be created us-

ing a bus coupler

If the current carrying capacity of the potential jumpers U

, U

, and GND is reached

(total current of U

and U

), a new power terminal must be used.

The Project+ software provides support when calculating the currents (see Section

“Appendix: Software support” on page 176).
