*Externer 2,2-kΩ Pull-Down-Widerstand zu Fahrzeugmasse (KL. 31)
ist erforderlich. Nicht geschützt vor einem Kurzschluss, wenn KL.31
nicht vorhanden ist. Daher wird ein 100 Ω-Widerstand bei jedem
Treiberausgang benötigt.

*External 2.2 kΩ pull-down resistor to chassis ground (KL.31) is re-
quired. Not protected against a short circuit in the event that KL.31
is missing. Therefore, a 100 Ω resistor is required on each driver out-
put.
