Section 2: Installation

Installation
2.4.5 Connect wiring and power up
It is recommended to use twisted pair wiring. To ensure proper communication, use 24 AWG to
14 AWG wire, and do not exceed 5000 feet (1500 meters).
Note
Proper electrical installation is necessary to prevent errors due to improper grounding and
electrical noise. Shielded wiring is recommended for environments with high EMI/RFI levels.
Shielded wiring is required in order to comply with NAMUR requirements.
Figure 2-9. Terminal blocks
To make connections, perform the following procedure:
1. Remove the cover on the field terminals side of the housing.
2. Connect the positive lead to the “PWR/COMM +” terminal, and the negative lead to the
“PWR/COMM –” terminal.
Note
Do not connect the power across the test terminals. Power could damage the test diode in the
test connection.
3. If the optional process temperature input is not installed, plug and seal the unused
conduit connection. If the optional process temperature input is being utilized, see
“Install optional process temperature input (Pt 100 RTD sensor)” on page 2-22 for more
information.
When the enclosed pipe plug is utilized in the conduit opening, it must be installed with
a minimum engagement of five threads in order to comply with
flameproof/explosion-proof requirements.
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. Reinstall the housing cover and tighten so that metal contacts metal to meet
flameproof/explosion-proof requirements.
2-10 shows the wiring connections necessary to power a 3051S MultiVariable transmitter and
enable communications with a hand-held 375 Field communicator.
