External Input Circuitry
The sum of the lengths of the supply lines to the source or
to the nearest capacitor ≥100 µF (a + b) should not exceed
5 m unless an external input filter with capacitor is fitted.
This filter is recommended in order to prevent power line
oscillations and reduce superimposed interference vol-
tages. See also: Technical Information : Application Notes .
