1 Additional external input filter or capacitor necessary.
External Input Circuitry
The sum of the lengths of the supply lines to the source or
to the nearest capacitor
≥100 F (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.
