STEP 2.Installing guide rails and wiring connectors
Guide rails
Positions of guide rails and wiring connectors are indicated in Figure 3,
page 6. Centers of guide rails should be 27 HP (27 TE) apart, for
example, at 1 HP (TE) and 28 HP (TE).
Wiring connectors
The applications platform is shipped with a solder-tail or screw-type
connector for input/output wiring, a keyed solder-tail or screw-type
connector for sensor wiring (Model 3500 only), and a plug-in connector
for power supply wiring.
Working from the front of the rack, use the supplied M2.5x8 screws to
install the wiring connectors onto the back of the rack as follows:
1. Use the centers of the guide rails as reference points and refer to
Figure 3, page 6.
2. Install the input/output wiring connector at 4 HP (4 TE) from the
neighboring unit or from the edge of the rack.
3. (Model 3500 only) Install the keyed sensor wiring connector at 16 HP
(16 TE) from the neighboring unit or from the edge of the rack.
4. Install the power supply wiring connector at 25 HP (25 TE) from the
neighboring unit or from the edge of the rack.

Guide rail centers should be 27 HP (27 TE) apart;
for example, 1 HP (1 TE) and 28 HP (28 TE)
Install screws and connectors from front of
rack.
• Model 3500 has six M2.5x8 screws
and three connectors.
• Model 3300 has four M2.5x8 screws
and two connectors.

STEP 3.Installing the Model 3300/3500 in the rack
1. Align the Model 3300/3500 with the guide rails.
2. Slide the Model 3300/3500 into the rack. Make sure the pins on the
back panel make contact with the wiring connectors.
3. Tighten the supplied captive screws to secure the front panel of the
Model 3300/3500 to the guide rails.

STEP 4.Connecting input and output wiring
Connect input and output wiring to the appropriate terminals on the
input/output wiring connector, which is the far right connector. Refer to
Table 1 and to the card that is inserted into the sleeve on the top panel
(shown in Figure 4).

•Use 24 to 16 AWG (0,25 to 1,5 mm
) twisted-pair shielded wire.
•Ground the shields at a single point only.

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.
8
5. At the transmitter:
a. Connect the color-coded wires to the appropriate terminals. To
identify the terminals, refer to Figure 5, page 8. 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.
STEP 6.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 6, page 10.
Referring to Figure 6, page 10, connect the Model 3300/3500 to a power
supply as follows:
2
1. Use 18 to 14 AWG (0,75 to 2,5 mm
) wire.
2. Ground the power supply wiring:
•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.
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 rack is required.
