n 1 Fieldbus cable from previous device (input)
n+1 Fieldbus cable to next device (output)
Connection at terminal carrier for loop topology
For flexible cables, the fieldbus connection can be made via spring clamp terminals
directly at the terminal carrier. For solid cables (single or multiple strands), additional
support terminals must be used. Refer to <Connection with support terminals> section
For two flexible wires per terminal, a joint wire end sleeve must be used (twin wire
end sleeve).

[XK] Terminal assignment according to wiring diagram (customer connection):
□ ▣ Channel 1 □ or channel 2 ▣ if further fieldbus devices follow
■ If the actuator is the last fieldbus device:
Channel 1: Link terminals 31/33 and 32/34
Channel 2: Link terminals 35/37 and 36/38
