[X] Shielding clamp
[X...] Terminal designation (X1, X2, X3, X4) according to wiring diagram
[S1/2] "Termination" switch for fieldbus termination

Functions of switches [S1] and [S2]
1)
Fieldbus termination channel 1 ONON[S1]
Fieldbus termination channel 1 OFFOFF
Fieldbus termination channel 2 ON (option)ON[S2]
Fieldbus termination channel 2 OFF (option)OFF
Upon delivery, the switches [S1] and [S2] are set to position OFF.1)
Cable connection
1. Always link A connections to green wire and B connections to red wire.
2. If the actuator is the final fieldbus device in the fieldbus segment:
2.1 Switch on the termination resistor for channel 1 using switch [S1] (position
ON).
2.2 For redundancy: Switch on the termination resistor for channel 2 using
switch [S2] (position ON).
Information: As soon as the termination resistors are switched on, the
connection to the next fieldbus device is automatically interrupted to avoid
multiple terminations.
3. Connect cable shield largely to shielding clamp [X].
