This installation manual explains basic installation guidelines for installing the Micro Motion
Model 3300 or Model 3500 MVD applications platform.

For information on I.S. applications, refer to Micro Motion approval documentation.
For complete instructions about configuration, maintenance, and service, refer to the

instruction manual shipped with the transmitter.

WARNING!

Improper installation in a hazardous area can cause an explosion.

For information about hazardous applications, refer to the appropriate Micro Motion approval
documentation, shipped with the meter or available from the Micro Motion web site.

WARNING!

Hazardous voltage can cause severe injury or death.

Install transmitter and complete all wiring before supplying power.

CAUTION!

Improper installation can cause measurement error or meter failure. Follow all instructions.

Planning

1.1 Installation kit

The installation kit includes a bezel, frame, two mounting brackets with screws, a power
supply wiring connector, and a retaining clip assembly for power supply wiring. See Figure

1-1).

The applications platform fits through a 5 7/16-inch (138 mm) square cutout in a panel
that is 5/64 inch (2 mm) to 1/2 inch (13 mm) thick. The bezel provides a IP65 watertight
seal between the panel cutout and the applications platform housing. See Figure 1-1.

In addition, the installation kit includes either:

• A bracketed wiring connector for screw-type connectors. See Figure 3-2.

• I/O cables and connectors. See Figure 3-3.

3.2.3 Wiring instructions for remote core processor with
remote transmitter installations

There are two phases to this procedure:

• Wiring the remote core processor to the transmitter

• Wiring the sensor to the remote core processor

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

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

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

Go to Step 8

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

not apply heat shrink – omit Step 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 3-11.

Figure 3-11: Gland nut and clamping insert

Wiring

6. For connection at the core processor housing, prepare shielded cable as follows (for
armored cable, omit steps d, e, f, and 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. See Figure 3-12. Cut off

the excess wire.

Installation Manual 21

Wiring

Figure 3-12: 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 3-13.

Figure 3-13: Shielded heat shrink covering exposed drain wires

g. Position the gland clamping insert so that 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 3-14.

Figure 3-14: Folded cloth

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

3-15.

10. Connect the core processor housing internal ground screw if earth ground is required.
Earth ground is required if the core processor cannot be grounded via sensor piping,

and local codes require internal ground connections.
Do not connect shield drain wires to this terminal.

11. Reinstall and tighten the core processor lid.

WARNING!

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

12. Connect the cable to the transmitter.

2. Plug the I/O cable connector onto the terminal block. Tighten
the captive screws to secure the connector to the terminal
block.

3. Connect the four wires from the core processor to the
appropriate terminals on the terminal block. See Table 3-3 and

Figure 3-9. No bare wires should remain exposed. Do not ground

the shield, braid, or drain wire(s) at the transmitter.

3.3 Wire the sensor to the remote core processor

CAUTION!

Do not allow the shield drain wires to contact the sensor junction box, as this can cause meter
errors.

1. Refer to Micro Motion’s 9-Wire Flowmeter Cable Preparation and Installation Guide and
follow the instructions on cable shielding and preparation.

• At the sensor end, follow the instructions for your cable type.

• At the core processor end, follow the instructions for your cable type with an MVD

transmitter.

2. To connect the wires, refer to Micro Motion’s 9-Wire Flowmeter Cable Preparation and
Installation Guide and follow the instructions for your sensor with an MVD transmitter.
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 3-17.

box.

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

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

CAUTION!

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

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

Connect the Model 3300 or Model 3500 to a power supply using the following steps:

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

2

) wiring to the power supply wiring connector.

See Figure 1-1.

2. Ground the transmitter as follows:

a. Connect the ground wire to the green power supply ground screw. See Figure 3-1.

b. Connect the power supply ground wire directly to earth ground.

c. Keep all ground leads as short as possible.

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

3. Plug the power supply wiring connector into the power supply wiring terminals. See

Figure 3-18.

4. Slide the retaining clip over the wiring, then tighten the screw to hold the clip in place.
See Figure 1-1.

5. (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
clause 5.4.3.d.
