Documentation

Before device installation begins, a licensed electrician must

attach a cable lug to the grounding cables that you supply. A cable with an

incorrectly attached lug can damage the device.

Before connecting the device to earth ground, review the following information:

Two pairs of threaded inserts (PEM nuts) are provided on the QFX3008-I Interconnect

device for connecting the device to earth ground. The first pair is sized for M6 screws

and is located below the wiring tray on the bottom left corner at the rear of the chassis.

The second pair is sized for UNC ¼-20 screws and is located below the second wiring

tray on the bottom right corner at the rear of the chassis. The grounding points are

spaced at 0.625 in. (15.86 mm). UNC ¼-20 screws with washers are provided in the

accessory kit.

The grounding lug required is a Panduit LCD2-14A-Q or equivalent. This grounding lug

is provided in the accessory kit.

The grounding cable that you provide for a QFX3008-I Interconnect device must be 2

AWG (33.6 mm

), minimum 60° C wire, or as permitted by the local code.

Only one of the two protective earthing terminals needs to be

permanently connected to earth ground.
