I/O Wiring – Model 2400S PROFIBUS-DP and DeviceNet Transmitters

4.3I/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.

3.Replace the user interface module and user interface cover.

Note: It is not necessary to open the power compartment to wire the outputs. Do not open the power compartment unless you are also wiring the power supply.

Note: The PROFIBUS cable shield is required to be grounded at both ends. At the 2400S, ground the cable shield in an appropriate cable gland. If an optional PROFIBUS-DP Eurofast M12 connector is used, the cable shield is grounded via the threads of the connector.

WARNING

Hazardous voltage can cause severe injury or death.

To avoid the risk of hazardous voltage, shut off the power before wiring the transmitter outputs.

WARNING

A transmitter that has been improperly wired or installed in a hazardous area could cause an explosion.

To avoid the risk of an explosion:

•Make sure the transmitter is wired to meet or exceed local code requirements.

•Install the transmitter in an environment that complies with the classification tag on the transmitter. See Appendix A.
