NOTE: 1 Inrush Current Protection Element (RT1) is installed to prevent a problem from occurring
in a surrounding circuit due to a great inrush current that generates at the opening/closing of Interlock Switch.
When Interlock Switch is closed, causing an inrush current to flow in RT1, the internal resistance of RT1 protects the circuit.
When 50ms has passed since Interlock was closed, FET (Q1) turns ON, leading to a stable power supply to the motors.
