CN101 is a connector for connecting AC Power. F101&F102 are fuse to protect all the circuit
AC. Input voltage is single 120V. CY101, CY102, CY103 are used high frequency noise of primary
between common GND.LX101,LX102,CX101, CX102 is used to filter low frequency noise. RX101,
RX102 and RX103 are used to discharge CX101 and CX102 remnants voltage
