You need the following materials to ground the chassis:

●Two 10-24 screws, 1 inch or shorter

●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.
