Typical configuration of a bus link for redundancy mode
Installing the bus link for redundant mode
1. Hook the lower edge of the BM Compact FF Link onto the rail, press it into the mounting
rail (a) and push it to the left until it engages (b).
If you are using the 482.6 mm or 530 mm mounting rail and position the BM Compact FF Link
in the right-hand engaged position, you can install two additional PS 307; 2A or one
PS 307; 5A to the left of the bus module.
