7.2.1 Select the cable with appropriate wire diameter, connect the power supply to the input terminal of the voltage
regulator, and the neutral wire must be connected.
7.2.2 The enclosure must be reliably grounded.
7.3 Inspection before power connection
7.3.1 The input supply voltage of the voltage regulator should be consistent with the input voltage range on the nameplate.
