止回路。 Two rectifiers are connected in series in opposite directions in a fault prevention circuit due to reverse connection of a DC power supply, which always outputs a voltage of normal polarity to the output terminal, regardless of the polarity of the voltage input to the input terminal. Then, connect two sets of circuits consisting of a relay coil connected in parallel to one of the rectifiers in parallel between the above input and output terminals, and connect two relay switches operated by these relay coils to the output terminals. A failure prevention circuit due to reverse connection of a DC power supply, characterized in that the above input and output terminals are connected to maintain proper polarity.
