Using Conduit Entries

Figure 2-9. Installing the 848L with Conduit Entries

Use the following steps to install the 848L with Conduit Entries:

1.Remove the junction box cover by unscrewing the four cover screws.

2.Remove the five conduit plugs and install five conduit fittings (supplied by the installer).

3.Run sensor and output wires through each conduit fitting.

4.Install the I/O wires into the correct screw terminals.

5.Install the power/signal wires into the correct screw terminals. Bus power is polarity insensitive, allowing the user to connect positive (+) or negative (–) to either Fieldbus wiring terminal labeled “Bus.” I/O power is polarity sensitive and must be connected correctly to avoid damage to the transmitter. See Figure 2-4 on page 2-5.

6.Replace the junction box cover and securely tighten all cover screws.
