Abstract
PURPOSE: The circuit which operates the return system relay only when the DC power source is connected in reverse polarity, and reverses the polarity of the DC power source to be connected to instruments, and is so constituted that, even if the DC power source is connected reversely, instruments are not broken, and normal operations can be performed.
