PROBLEM TO BE SOLVED: To provide a power connection system to suppress increase in circuit scale and cost and prevent increase of power consumption by a bleeder resistor and heat generation. SOLUTION: The power connection system is provided with a circuit board having a logic circuit, a power supply unit supplying power to the circuit board, a power supply line which is connected between the power supply unit and the logic circuit for power supply, a ground line, a reset signal line transmitting a reset signal from the power supply unit to the logic circuit, and a transistor which has the bleeder resistor installed between the power supply line and the ground line, is connected between the bleeder resistor and the ground line and has a switch function controlling on/off connection of the bleeder resistor to the power supply unit in accordance with on/off of the reset signal.
