Mounting 2 Mounting 2.1 Mount the core processor Use this section only if you are installing a remote transmitter using a remote core processor or a remote enhanced core processor. See Figure 1-5. If you have a 4-wire remote installation, go to Section 3.1. Figure 2-1 shows both types of core processors and mounting bracket. Using the mounting bracket, mount the core processor in a location compatible with the cable length requirements discussed in Section 1.2.

Wiring Refer to the label attached to the terminal block. See Figure 3-5 and Figure 3-2. • Use 24 to 16 AWG (0,25 to 1,5 mm2) twisted-pair shielded wire • Ground the shields at a single point only The I/O terminal block ground is available for continuation of user cable shielding to I/ O cable shielding. The cable connector does not connect the I/O cable shielding to the chassis ground.

Wiring 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 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.
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.
Wiring Figure 3-15: 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. The 4-wire cable supplied by Micro Motion consists of one pair of 18 AWG (0,75 mm2) wires (red and black) for the VDC connection, and one pair of 22 AWG (0,35 mm2) wire (green and white) for the RS-485 connection. 9. Connect the four wires to the numbered slots on the core processor. See Figure 3-16.
Wiring Connection type Procedure Screw-type connectors Connect the four wires from the core processor to the appropriate terminals on the transmitter. See Table 3-3 and Figure 3-6. • Do not expose bare wires. • Do not ground the shield, braid, or drain wires at the transmitter. I/O cables 1. Attach the supplied terminal block to a DIN rail. The terminal block accommodates various rail types. See Figure 3-8. 2. Plug the I/O cable connector onto the terminal block.

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.
Wiring 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 mm2) 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.
