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 super-
imposed interference voltages. See also: Technical Infor-
mation : Application Notes .
