5.3 Power conditioner
A fieldbus segment requires a power conditioner to isolate the power supply,
filter, and decouple the segment from other segments attached to the same
power supply.
5.4 Grounding
Signal wiring of the fieldbus segment can not be grounded. Grounding one of the
signal wires will shut down the entire fieldbus segment.
Transmitter case grounding
Always ground the transmitter case in accordance with national and local
electrical codes. The most effective transmitter case grounding method is a
direct connection to earth ground with minimal impedance. Methods for
grounding the transmitter case are listed below.
Internal ground connection
The internal ground connection screw is inside the FIELD TERMINALS side of the
electronics housing. This screw is identified by a ground symbol ( ). The ground
connection screw is standard on all Rosemount 3051SMV Transmitters (see
Figure 8).

External ground connection
The external ground connection is located on the exterior of the transmitter
housing (see Figure 9). This connection is only available with option D4 and T1.
