Figure 6-40 Overvoltage protection for the air-ultrasonic sensor
Please observe the non-reversed connection of the DataPro (p-side
to transmitter) and a correct, straight wiring supply. Ground
(earth) must lead to the unprotected side.
Please note that incorrect wiring will deactivate the overvoltage
protection function.
