Abstract: An interlock device for a bypass device, which includes a Rack In Rack Out (RIRO) mechanism, configured to drive an Automatic Transfer Switching Equipment (ATSE) from a non-operating position to an operating position and drive the ATSE from the operating position to the non-operating position. Further, the interlock device includes a first interlock mechanism which is configured to prevent the RIRO mechanism from driving the ATSE from the non-operating position to the operating position when the first switch and the fourth switch are both switched on. The interlock device also includes a second interlock mechanism which is configured to prevent the RIRO mechanism from driving the ATSE from the non-operating position to the operating position when the second switch and the third switch are both switched on.
