Grounding the BlackDiamond 8810 Chassis
Although grounding the BlackDiamond 8810 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.
To ground the chassis:
1 Locate the grounding point on the back of the chassis ( Figure 53 ).
