n 1 Fieldbus cable from previous device (input)
n+1 Fieldbus cable to next device (output)
[XK] Terminal assignment according to wiring diagram (customer connection):
Channel 1: Terminals 31, 32 and 33, 34
Channel 2: Terminals 35, 36 and 37, 38 (AUMA redundancy I or II)
Connect fieldbus cables:
1. Connect bus cables.
Always link A connections to green wire and B connections to red wire.
2. If the actuator is the final device in the fieldbus segment (line topology only):
2.1 Connect termination resistor for channel 1 through linking the terminals
31 - 33 and 32 - 34 (standard)
2.2 For AUMA redundancy I or II: Connect termination resistor for channel 2
through linking the terminals 35 - 37 and 36 - 38.
