CBN and IBN support
The 7705 SAR-F supports both Common Bonding Networks (CBN) and Isolated Bonding
Networks (IBN). The battery terminals (labeled +Batt A, -Batt A, +Batt B, and -Batt B on
the chassis) are floating inputs relative to digital or chassis ground within the chassis.

7705 SAR-F Installation Guide
In an IBN installation, the chassis ground terminal must be connected to ground at the
building ground point.
In a CBN installation, if you use the 7705 SAR-F chassis ground stud (located on the
right-hand side mounting bracket) to connect the chassis ground terminal(s) to the frame
ground on the rack, then you must use a second nut on the stud to secure the
attachment. The first nut is used to secure the building ground point wire to the chassis
ground stud, and that connection must be a single-purpose permanent connection.
