1 Surges up to 156 V for 2 s (complying to LES-DB standard for VN = 110 V).
2 With external input capacitor Ce = 470 F/200 V and option L.
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:
