INSTALLATION

Using Cable Glands

Figure 2-8. Installing the 848L with Cable Glands

Use the following steps to install the 848L with Cable Glands:

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

2.Run the sensor and power/signal wires through the appropriate cable glands using the pre-installed cable glands (see Figure 2-8).

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

4.Install the power/signal wires onto 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.

5.Replace the enclosure cover and securely tighten all cover screws.
