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 2.0 m (3.0 m twisted). An external input filter
(FP 144, see Accessories) is recommended in order to
prevent power line oscillations and reduce superimposed
interference voltages. See also: Technical Information.
