Surges/transients
The indicator will 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 indicator.
Optional transient protection terminal block
The transient protection terminal block can be ordered as an installed option (Option code T1 in the
indicator model number) or as a spare part. The spare part number is 03151-4134-0002. The lightning
bolt symbol shown identifies it as a transient protection terminal block.
Note
The fieldbus physical layer specification requires indicator communication during extreme operating
conditions of 250 V
rms
common mode signal. The transient terminal block was designed to limit
common mode voltages to 90 V and cannot be used in these extreme operating conditions.
