In RCD mode, the <RESET> button is used not only to reset the residual current device, but
also as a mechanical indication that the unit has "tripped". If a residual current is detected or
the button <TEST> is pressed, the button <RESET> is automatically released and so signals
that the residual current device has tripped. Even when the residual current device is at zero
potential, the <RESET> remains in the "TRIP" position.
