Cable lengths

Maximum cable length from the sensor to the Model 3700 transmitter depends on the installation type and cable type:

4-wire remote transmitter: see Figure 5, then refer to Table 1 for maximum length of the 4-wire cable.

Remote core processor with remote transmitter: see Figure 6, then refer to Table 1 for maximum length of the 4-wire cable and the 9-wire cable.

If you are installing the Model 3350 applications peripheral in combination with a transmitter, the maximum cable length from the transmitter’s frequency output to the Model 3350’s frequency input is 500 feet (150 meters).

STEP 2. Preparing conduit openings for ATEX Zone 1

If the Model 3350/3700 carries an ATEX Zone 1 approval:

1.Remove thread protectors from conduit openings (see Figure 7).

2.Install factory-supplied cable glands or user-supplied EExe cable entry devices in conduit openings that are in use.

3.Install EExe plugs in conduit openings that are not in use.

STEP 3. Orienting the Model 3350/3700 (optional)

The Model 3350/3700 can be oriented on the mounting bracket as needed, and the display cover can be rotated on the applications platform. Figure 7 provides orientation examples.

To orient the Model 3350/3700:

1.Use the four supplied mounting bolt assemblies.

2.Using a 13 mm hex wrench, install the bolt assemblies to 12 ft-lb (16 Nm) of torque.

To rotate the display cover, if needed, see the transmitter installation manual.
