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 option L is fitted. This option is recommended
in order to prevent power line oscillations and reduce su-
perimposed interference voltages. See also: Technical In-
formation : Application Notes .
