Quick Start Guide
Note
Grounding the transmitter case via threaded conduit connection may not provide sufficient
ground continuity.
Transient protection terminal block grounding
The transmitter can withstand electrical transients of the energy level usually
encountered in static discharges or induced switching transients. However,
high-energy transients, such as those induced in wiring from nearby lightning
strikes, can damage the transmitter.
The transient protection terminal block can be ordered as an installed option
(option code T1) or as a spare part to retrofit existing Rosemount 3051SMV
Transmitters in the field. The lightning bolt symbol shown in Figure 10 identifies
the transient protection terminal block.

Note
The transient protection terminal block does not provide transient protection unless the
transmitter case is properly grounded. Use the guidelines to ground the transmitter case
(see “Grounding” on page 11).
5.5 Signal termination
A terminator should be installed at the beginning and end of every fieldbus
segment.
