Grounding the BlackDiamond 8806/12804 Chassis
Although grounding the BlackDiamond 8806/12804 chassis is optional, it is recommended. A grounding
point with integrated pem-nuts is provided on the back of the chassis.
You need the following materials to ground the chassis:
● Two 10-24 screws
● One copper, standard barrel 2-hole compression grounding lug, type LDC, equivalent to Panduit
part number LCD4-14A-L or Thomas & Betts part number: LCN4-14
● Appropriate grounding wire for your system, based on the available input current for the power
supply:
■ For AC systems using a 20A breaker per PSU (SSI AC), the chassis ground can be as small as
14 AWG.
■ For DC systems using a 40A breaker per PSU (SSI DC), the chassis ground can be as small as
10 AWG.
