External Input Circuitry
The sum of the lengths of the supply lines to the source or
to the nearest capacitor
≥100 F or to the nearest external
input filter which includes such a capacitor (a + b) should
not exceed 0.3 m (0.5 m twisted). An external input filter
(FP 38 or FP 80, see Accessory Products) is recommen-
ded in order to prevent power line oscillations and reduce
superimposed interference voltages. See also:
