1.6

Wiring

The wiring directions are different depending upon the

configuration of your particular transmitter. Choose the

appropriate configuration from the following sections and

follow the directions carefully.

1.6.1 Two-Wire Transmitter without Meter

WARNING: These units are designed to operate with voltages

between 14 VDC and 40 VDC only. Application of 120

VAC will destroy the transmitter.

Caution: All power must be turned off until all of the wiring connec-

tions have been made.

All wiring between the power supply and the transmitter

should be done with 16 AWG to 22 AWG shielded twisted

pair. The connection is made at the terminal strip within

the transmitter enclosure.

1. Remove the transmitter housing cover. Pull the power

supply wires through the conduit connection.

2. Connect the positive supply wire to the (+) terminal and

the negative supply wire to the (–) terminal. Connect the

shield to the green ground screw at the base of the hous-

ing. Make the shield wire as short as possible. Refer to

Figure 3 on page 3, and Figure 5.

3. Replace the transmitter housing cover until calibration.

4. Connect the positive supply wire to the positive terminal

on the power source. Connect the negative supply wire to

the negative terminal on the power source. Connect the

shield to the power source’s ground terminal and apply

power. The yellow LED on the potted module should be on.

5. Proceed to Calibration, Section 1.7.

1.6.2 Two-Wire Transmitter with Meter

WARNING: These units are designed to operate with voltages

between 14 VDC and 40 VDC only. Application of 120

VAC will destroy the transmitter.

Caution: All power must be turned off until all of the wiring connec-

tions have been made.

All wiring between the power supply and the transmitter

should be done with 16 AWG to 22 AWG shielded twisted

pair. The connection is made at the terminal strip within

the transmitter enclosure.

1. Remove the meter housing cover.

2. Remove the two screws holding the meter bracket to the

housing. Pull the meter gently out of the housing, being

careful not to disturb the wiring. Lay it on one side.
