Quick Start Guide
Use the following steps to wire the transmitter:
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. Tighten the terminal screws to ensure full contact with the 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.
Note
The use of a pin or ferrule wire terminal is not recommended as the connection may be
more susceptible to loosening over time or under vibration.
4. Ground housing to fulfill local grounding regulations.
5. Ensure proper grounding. It is important that the instrument cable shield be:
a. Trimmed close and insulated from touching the transmitter housing
b. Connected to the next shield if cable is routed through a junction box
c. Connected to a good earth ground at the power supply end
6. If transient protection is needed, refer to section
“Grounding for transient
terminal block” on page 11
for grounding instructions.
7. Plug and seal unused conduit connections.
8. Replace the housing cover.
Figure 7. Wiring
Installation of the transient protection terminal block does not provide transient protection unless
the Rosemount 3051 case is properly grounded.
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment.
Do not connect the powered signal wiring to the test terminals. Power could damage the test diode
in the terminal block.
A. Minimize distance
B. Trim shield and insulate
C. Protective grounding terminal
D. Insulate shield
E. Connect shield back to the power supply ground
