Inverter is in undervoltage
OFF
Inverter is in normal condition
Valid for inputs:
11, 12, AL0 – AL2
Example for terminal [11] (default output
configuration shown – see

Notes:
•
The example circuit for terminal [11] drives a relay
coil. Note the use of a diode to prevent the
negative-going turn-off spike generated by the coil
from damaging the inverter’s output transistor.
