1 BEFORE YOU BEGIN This quick reference guide e xplains basic installation guidelines for installing the Micro Motion ® Model 3350/370 0 MVD applications platform.
2 European installations This Micro Motion product complies with all applicable European directiv es when properly installe d in accordance with th e instructions in this quick reference guide. Refer to the EC declaration of conformity for directiv es that apply to this product.
3 STEP 1. Choosing a location Choose a location for the tr ansmitt er based on the requirements described below . Environmental requ irements Install the Model 3350/3700 ac cording to specif ied limits: • Ambient temperature: –4 to +140 °F (–20 to +60 °C ) Dimensions See Figures 2, 3, and 4 fo r Model 3350/3700 dimensions.

7 STEP 2. Preparing con duit openings for A TEX Zone 1 If the Model 3350/3700 carries an A TEX Zone 1 approv al: 1. Remov e thread protectors from conduit openings (see Figure 7). 2. Install factory-supplied c able glands o r user-supplied EExe cable entry de vices in conduit op enings that are in use.
8 STEP 4. Mounting the applications platform For flat-surf ace mounting, see Figure 8. For po le mounting, see Figure 9. Figure 8. Mounting to a flat s urface Figure 9. Mounting to a pole 4 x 5/16-inch or M8 bolt (user-supplied) • Mount al l four bolts to the same surface.
9 STEP 5. Mounting the core processor This step is required only for re mote core processor with remote transmitter installations (see Figure 6). If you ha ve a 4-wire remote installation, go to Step 6. Figure 10 sho ws the remote core pro cessor and mounting bracket.

11 Figure 12. Wiring terminal labels STEP 7. Connecting the Mod el 3700 to the sensor If you are installing the Model 3350 appli cations pe ripheral, this step is not required. Go to Step 8. T o connect the Model 37 00 transmitter to a Micro Motion sensor , follow the instructions in this section.
12 Installation options The Model 3700 can be wired to the sensor in either of the following confi gurations: • 4-wire remote transmitter (requires a 4-wire cable; see Figure 5 and W iring instructi.

14 Wiring instructions for remote core processor with remote transmitter There are two phases to this procedure: • W iring the remote core pr ocessor to the transmitter • W iring the sensor to the remote core processor T o wire the remote core processor to the tr ansmitter: 1.
15 4. For connection at the core processo r housing , prepare shielded c able as follo ws (for armored cable, omit steps d, e, f, g): a. Strip 4 1/2 inches (114 mm ) of cable jacket. b . Remo ve the clear wrap that is inside the cable jacket, and remo ve the f iller material between the wires.
16 g. Position gland clamping insert so the interior end is flush with the heat shrink. h. Fold the cl oth shield or braid and drain wires over the clamping insert and approximately 1/8 in ch (3 mm) past the O-ring. i. Install the gland body into th e core processor housing conduit opening.
17 7. Reinstall and tighten the core processor lid. 8. T o connect the cable to the transm itter , connect the four wires from the core processor to the appropriate terminals on the transmitter . See T able 3 and Figure 13. No bare wires should remain e xposed.
18 1. Refer to Micro Motion’ s 9-W ir e Flowmeter Cable Pr epar ation and Installation Guide for instructions on cable shielding and preparatio n: • At the sensor end, follo w the in structions for your cable type. • At the core processor end, follo w the instructions for your cable type with an MVD transmitter .
19 If using shielded or armored cable: a. Ground the shield dra in wires (the black wire) only on the co re processor end, by connecting it to the ground screw inside the lo wer conduit ring. Do not ground to the core pro cessor’ s mounting scre w .
20 Connect the Model 33 50/3700 to a po wer supply as follo ws: 1. Use 18 to 12 A WG (0,75 to 4,0 mm 2 ) wire. 2. Using a flat-head screwdri ver , loos en the captiv e screws that secure the display cov er to the housing. 3. Ground the transmitter as follo ws: • Connect the ground wire to the green screw (p ower supp ly ground; see Figure 11).
