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.
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
numbers. The lightning bolt symbol shown in
terminal block.
