From the factory, the SG, ETH and PBXG grounds are located inside the chassis and are connected to
the FG ground (frame ground) on the back of the Chassis-B.
●
Each 9.5" Chassis-B or 19" Chassis-A in the system must be grounded separately following the step
below.
1. Ground each 9.5" Chassis-B or 19" Chassis-A by connecting a 14 AWG wire from the FG lug on the back
side of the chassis to an electrical service ground (such as a cold water pipe).
