Applications

The FS/Q locks are used to ensure that multiple supplies are not applied to common bus bars. When all incomers are closed the bus bars are open. To close a bus bar, first the incomers must be switched to open.

In the shown is application to close Bus 1, either incomer AA or AB must be opened. The key is removed from either AA or AB connection and is then inserted into the bus switch A_ (A BLANK). To close Bus 2, either incomer AB or BB must be opened and the key AB or BB transferred to the switch _B (BLANK B).
