2.6 O-rings with flange adapters
WARNING
Failure to install proper flange adapter O-rings may cause process leaks,
which can result in death or serious injury. The two flange adapters are
distinguished by unique O-ring grooves. Only use the O-ring that is designed
for its specific flange adapter, as shown below.

B. O-ring
C. PFTE-based profile (square)
D. Elastomer profile (round)
Whenever the flanges or adapters are removed, visually inspect the O-rings.
Replace them if there are any signs of damage, such as nicks or cuts. If you
replace the O-rings, re-torque the flange bolts and alignment screws after
installation to compensate for seating of the PTFE O-ring.
2.7 Environmental seal for housing
For NEMA® 4X, IP66, and IP68 requirements, use thread sealing (PTFE) tape
or paste on male threads of conduit to provide a water and dust tight seal.
Consult factory if other ingress protection ratings are required.
Always ensure a proper seal by installing the electronics housing cover(s) so
that metal contacts metal. Use Rosemount O-rings.
For M20 threads, install conduit plugs to full thread engagement or until
mechanical resistance is met.

5 Connect the wiring and power up
Figure 5-1 shows wiring connections necessary to power a Rosemount 3051
and enable communications with a handheld communicator.
Use the following steps to wire the transmitter:
Procedure
1. Remove the housing cover on the field terminals side.
2. Connect the positive lead to the “+” terminal (PWR/COMM) and the
negative lead to the “–” terminal.
3. Ensure full contact with terminal block screw and washer. When
using a direct wiring method, wrap wire clockwise to ensure it is in
place when tightening the terminal block screw.
The use of a pin or a ferrule wire terminal is not recommended as the
connection may be more susceptible to loosening over time or under
vibration.
4. Ensure proper grounding.
It is important that the instrument cable shield:
•Be trimmed close and insulated from touching the transmitter
housing
•Be connected to the next shield if cable is routed through a
junction box
•Be connected to a good earth ground at the power supply end
Do not connect the powered signal wiring to the test terminals.
Power could damage the test diode in the test connection. Shielded
twisted pair cable should be used for best results. Use 24 AWG or
larger wire and do not exceed 5,000 ft (1500 m).
5. Plug and seal unused conduit connections.
6. 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.
7. Replace the housing cover.

5.1 Signal wiring grounding
Do not run signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. Grounding terminations are provided on the
outside of the electronics housing and inside the terminal compartment.
These grounds are used when transient protect terminal blocks are installed
or to fulfill local regulations. See Step 2 for more information on how the
cable shieldshould be grounded.
