(4) Smoothing capacitor (C510, C511)
This smoothes (averages) the voltage rectified by the diode stacks.
ADC vorlege is generated in the same way as in NENG: 1-3.
(5) C507, C508, C512, C513, C506, NF COIL1
These absorb electrical noise generated during operation of compressor, and also absorb external noise entering
from power line to Brotert electronic parts.
(6) Surge shanise varistor-1, 2, 3, 4
These absorbs external ees surge.

(7) Inrush-protective resistor
This works to protect from overcurrent when
power is turned on.
<Reference>

,
When inrush protective resistor is defective, diode
stack may malfunction. As a result, DC voltage is not
generated and no operation can be done.
