• Two zinc-plated steel lockwashers
• Two zinc-plated steel nuts
• One Panduit-style, standard two-hole barrel, copper compression lug
• AWG, high-strand-count copper wire cable, appropriate for your chassis
— 8 AWG for the Alpine 3808
— 10 AWG for the Alpine 3804
— 14 AWG for the Alpine 3802
• Flathead screwdriver
To ground the chassis:

torque.
4 Attach the ground lug, lock washers, and nuts (in that order) to the grounding studs on the rear of
the chassis. Tighten the nuts to 125 inch-pounds of torque.
After the chassis is installed, install power supplies and connect power as described in Chapter 8. Then
install required modules as described in Chapter 9 and Chapter 10.
Grounding the Alpine 3804 or 3806 Chassis
To ground the Alpine 3804 or 3906 chassis, gather the following materials:
• Two 1/4-20 screws
• One copper, standard barrel 2-hole compression grounding lug, type LDC, equivalent to Panduit
part number LCD4-14B-L
• Appropriate grounding wire for your system, based on the available input current for the power
supply:
— For AC systems using a 20-Amp breaker per PSU (SSI AC), the chassis ground can be as small as
14 AWG.
— For DC systems using a 40-Amp breaker per PSU (SSI DC), the chassis ground can be as small as
10 AWG.
