I/O wiring for Model 2400S PROFIBUS-DP transmitters
To connect the I/O wiring for a 2400S PROFIBUS-DP transmitter:
1. Remove the user interface cover and user interface module. See Section 2.4 for instructions.
2. Wire the transmitter to the PROFIBUS-DP segment according to the diagram in Figure 4-1.
Follow all local safety regulations.
