Note:

The XPL_ENABLE signal is not connected by default. If it is necessary to control this signal, add resistor R71 (0Ω).
The XPL_STBY signal is not connected by default. If it is necessary to control this signal, add resistor R68 (0Ω).
The XPL_VZC signal is not connected by default. If it is necessary to control this signal, add resistor R57 (0Ω). See Zero-Crossing Detector Circuit for additional information.
