Grounding the transmitter case via threaded conduit connection may not provide sufficient
ground continuity.
Grounding transient protection terminal block
The transmitter can withstand electrical transients of the energy level usually encountered
in static discharges or induced switching treatments. However, high-energy transients,
such as those induced in wiring from nearby lightning strikes, can damage the transmitter.
You can order the transient protection terminal block as an installed option (option code
T1) or as a spare part to retrofit existing transmitters in the field. See the Spare parts
section of the
