European installations

This Micro Motion product complies with all applicable European
directives when properly installed in accordance with the instructions in
this quick reference guide. Refer to the EC declaration of conformity for
directives that apply to this product.

The EC declaration of conformity, with all applicable European
directives, and the complete ATEX Installation Drawings and Instructions
are available on the internet at www.micromotion.com/atex or through
your local Micro Motion support center.

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).

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.

In addition, the installation kit includes:

• A bracketed wiring connector for screw-type connectors (see Figure 5,
page 5), or

• I/O cables and connectors (see Figure 7, page 7)

below.

Environmental requirements

Install the transmitter where ambient temperature is between

–4 and

+140 °F (–20 and +60 °C).

Dimensions

If the Model 3300/3500 has screw-type wiring connectors, see Figure 2
for dimensions. If the Model 3300/3500 has I/O cables, see Figure 3,

Flowmeter cable lengths

Maximum cable length from the sensor to the Model 3500 transmitter is
1000 feet (300 meters).

If you are installing the Model 3300 applications peripheral in
combination with a transmitter, the maximum cable length from the
transmitter’s frequency output to the Model 3300’s frequency input is
500 feet (150 meters).

STEP 2. Installing the Model 3300/3500 in the panel

Refer to Figure 4, page 5, and follow these steps:

1. Insert the Model 3300/3500 through the cutout.

2. Slide the frame over the housing.

3. Insert the posts on the brackets into the rails on the housing.

4. Tighten the screws evenly to 10 to 14 inch-pounds (1,13 to 1,38 Nm)
to ensure a watertight seal between the gasket and the panel.

STEP 4. Connecting the Model 3500 to the sensor

To connect the Model 3500 transmitter to a Micro Motion sensor, follow
the steps below. If you are installing the Model 3300 applications
peripheral, this step is not required.

Sensor wiring depends on the connectors supplied with the Model 3500:

• Screw-type connectors

•I/O cables

Follow the steps below to connect the Model 3500 to the sensor.

1. Identify the components:

• See Figure 10 for transmitters with screw-type connectors.

• See Figure 11, page 10, for transmitters with I/O cables.

2. Prepare the cable according to the instructions in Micro Motion’s
9-Wire Flowmeter Cable Preparation and Installation Guide.

3. Ensure that the cable has 360° shielding, continuous from the
transmitter to the sensor’s junction box. Two methods can be used:

• Metallic conduit

• Shielded or armored cable

Refer to Micro Motion’s 9-Wire Flowmeter Cable Preparation and
Installation Guide for specific instructions.

4. At the sensor:

a. Clip the cable drain wires.

b. Connect wiring inside the junction box housing and tighten the

screws to hold the wires in place.

For information on your sensor’s junction box terminals, see the
sensor installation manual or Micro Motion’s 9-Wire Flowmeter
Cable Preparation and Installation Guide.

5. At the transmitter:

• For transmitters with screw-type connectors:

a. Connect the color-coded wires to the appropriate terminals.

To identify the terminals, refer to Figure 10, page 9. No bare
wires should remain exposed.

b. If using shielded or armored cable, connect the cable braid to

the rear stud, as described in Micro Motion’s 9-Wire
Flowmeter Cable Preparation and Installation Guide.

• For transmitters with I/O cables:

a. Attach the supplied terminal block for sensor wiring to a DIN

rail. The terminal block fits various rail types (see Figure 12).

b. Plug the connector for sensor wiring onto the terminal block.

Tighten the captive screws to secure the connector to the
terminal block.

c. Connect the color-coded wires to the appropriate terminals on

the terminal block. To identify the terminals, refer to
Figure 11, page 10. No bare wires should remain exposed.

d. If using shielded or armored cable, connect the cable braid to

the terminal as shown in Figure 11, page 10.

STEP 5. Connecting power supply wiring

CAUTION

Improper wiring installation can cause device failure
or measurement error.

• To avoid device failure or measurement error, do not
install power supply wiring in the same cable tray or
conduit as input/output wiring.

• Shut off power supply before installing the applications
platform.

• Make sure power supply voltage matches voltage that
is indicated on power supply wiring terminals. See
Figure 13, page 13.

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

1. Plug in the power supply wiring connector. See Figure 13, page 13.

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

2

) wiring to the power supply

wiring connector.

3. Ground the power supply wiring:

• Connect the ground wire to the ground lug for the power supply.

• 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.

4. Connect wires to the power supply wiring terminals as shown in
Figure 13, page 13.

5. Slide the retaining clip over the wiring, then tighten the screw to hold
the clip in place. See Figure 1, page 2.

A user-supplied switch may be installed in the power supply line. For
compliance with low-voltage directive 73/23/EEC (European
installations), a switch in close proximity to the Model 3300/3500 is
required.
