There are two phases to this procedure:

• Wiring the remote core processor to the transmitter

• Wiring the sensor to the remote core processor

Wiring

To wire the remote core processor to the transmitter:

1. Use one of the following methods to shield the wiring.

Installation method Procedure

Unshielded wiring in continuous metallic conduit that provides 360°
termination shielding for the enclosed wiring

A user-supplied cable gland with shielded cable or armored cable,
terminate the shields in the cable gland. Terminate both the armored
braid and the shield drain wires in the cable gland

A Micro Motion-supplied cable gland at the core processor housing Go to Step 2

Go to Step 8

Go to Step 8

2. Do one of the following:

• If you are using shielded cable, prepare the cable and apply shielded heat shrink

as described in Step 6. The shielded heat shrink provides a shield termination
suitable for use in the gland when using cable whose shield consists of foil and not
a braid. Go to Step 3.

• If you are using armored cable, prepare the cable as described in Step 6, but do

not apply heat shrink – omit Steps 6d, e, f, and g. Go to Step 3.

3. Identify the components shown in Figure 2-1.

4. Remove the core processor lid.

5. Slide the gland nut and the clamping insert over the cable. See Figure 3-4.

6. For connection at the core processor housing, prepare shielded cable as follows (for
armored cable, omit steps d, e, f, g):

a. Strip 4 1/2 inches (114 mm) of cable jacket.

b. Remove the clear wrap that is inside the cable jacket, and remove the filler material

between the wires.

c. Remove the foil shield that is around the insulated wires, leaving 3/4 inch (19 mm)

of foil or braid and drain wires exposed, and separate the wires.

d. Wrap the shield drain wires around the exposed foil twice. Cut off the excess wire.

Figure 3-5: Shield drain wires wrapped twice around exposed shield foil

e. Place the shielded heat shrink over the exposed shield drain wires. The tubing

should completely cover the drain wires.

f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing. See

Figure 3-6.

Installation Manual 17

Wiring

Figure 3-6: Shielded heat shrink covering exposed drain wires

g. Position gland clamping insert so the interior end is flush with the heat shrink.

h. Fold the cloth shield or braid and drain wires over the clamping insert and

approximately 1/8 inch (3 mm) past the O-ring. See Figure 3-7.

Figure 3-7: Folded cloth

i. Install the gland body into the core processor housing conduit opening. See Figure

3-8.

Figure 3-8: Installing the gland body

7. Insert the wires through the gland body and assemble the gland by tightening the
gland nut.

8. Identify the wires in the 4-wire cable.
Use the 4-wire cable supplied by Micro Motion. This cable consists of one pair of 18

AWG (0,75 mm

2

) wires (red and black) for the VDC connection, and one pair of 22

Do not connect shield drain wires to this terminal.

11. Reinstall and tighten the core processor lid.

Do not twist the core processor, as this will damage the sensor.

Additional information for connecting the wires at the core processor is provided
below:

a. Identify the components shown in Figure 2-1.

b. Remove the core processor’s end-cap.

c. Insert the 9-wire cable through the conduit opening.

d. Connect the wires to the plugs supplied with the core processor.

e. Insert the plugs into the sockets inside the lower conduit ring. See Figure 3-10.

3. Ground the cable.

Cable type Procedure

Jacketed cable Ground the shield drain wires (the black wire) only on the core

processor end, by connecting it to the ground screw inside the
lower conduit ring. Do not ground to the core processor’s
mounting screw. Do not ground the cable at the sensor junction
box.

Shielded or armored cable Ground the shield drain wires (the black wire) only on the core

processor end, by connecting it to the ground screw inside the
lower conduit ring. Do not ground to the core processor’s
mounting screw. Do not ground the cable at the sensor junction
box.

Ground the cable braid on both ends, by terminating it inside the
cable glands.

4. Ensure integrity of gaskets, grease all O-rings, then close the junction box housing and
core processor end-cap, and tighten all screws.

CAUTION!

20 Model 3500 Transmitters or Model 3300 Peripherals - Rack Mount

Make sure that the wires are not caught or pinched when you close the housing to reduce the risk of
measurement error or meter failure.

3.4 Connect the power supply wiring

Power supply wiring terminals

Terminal designations for AC power

Terminal designations for DC power

CAUTION!

• Do not install power supply wiring in the same cable tray or conduit as the input/output

wiring to avoid device failure or measurement error.

• Shut off the power supply before installing the applications platform.

• Make sure the power supply voltage matches the voltage that is indicated on the power

supply wiring terminals. See Figure 3-11.

Connect the Model 3300 or Model 3500 to a power supply as follows:

1. Use 18 to 14 AWG (0,75 to 2,5 mm

2. Ground the transmitter as follows:

• Connect the ground wire to the middle terminal.

• Connect the power supply ground directly to earth ground.

• Keep all ground leads as short as possible.

• Ensure that all ground wiring has less than 1 ohm impedance.

3. Connect wires to the upper and lower terminals.

4. (Optional). Install a user-supplied switch in the power supply line.
In Europe, install the switch close to the Model 3300 or Model 3500 in order to comply

with low-voltage directive 2006/95/EC. For details, see standard EN 61010-1:2010
