When the high voltage side is powered off, when the secondary working power is connected, press the self-check button, the L1, L2, L3 indicator lights showing high voltage should light up, and the output contacts of the locking relay should be disconnected; release the button, the L1, L2, L3 indicator lights go out, and the output contacts of the locking relay are closed.
2. When the high voltage terminal voltage reaches or exceeds 40% of the nominal voltage, regardless of whether the secondary power is connected, press the button, the L1, L2, L3 indicator lights showing high voltage are on, and the output contacts of the locking relay are disconnected.
Function of the power test switch
1. When the high voltage side is powered off, press the power test switch, and the L1, L2, and L3 indicator lights showing that the high voltage is energized should not light up;
