STEP 4: CONNECT WIRING AND POWER UP

Use the following steps to wire the transmitter:

1.Remove the housing cover labeled “Field Terminals.”

2.Connect the positive lead to the “+” terminal, and the negative lead to the “–” terminal.

NOTE

Do not connect the power across the test terminals. Power could damage the test diode in the test connection. Twisted pairs yield best results. For single compartment housing (Junction Box housing), shielded signal wiring should be used in high EMI/RFI environments. Use 24 AWG to 14 AWG wire and do not exceed 5,000 feet (1500 meters).

3.Plug and seal the unused conduit connection.

4.If applicable, install wiring with a drip loop. Arrange the drip loop so the bottom is lower than the conduit connections and the transmitter housing.

5.Replace the housing cover.

The figures below show the wiring connections necessary to power a 3051S and enable communications with a hand-held Field Communicator.
