Grounding Cables
Rack equipment is bonded through the screws that fasten the equipment chassis
to the frame of the rack. Therefore, it is necessary to provide a reliable
low-impedance connection between the rack frame and the site grounding bus
using copper conductors.
Connect the rack grounding screw and the site grounding bar with a 2 AWG
(35 mm
2
) or thicker copper lead with green/yellow insulation, in compliance
with UL/ETSI recommendations. The RAP end of the lead must be terminated
in an M6 lug suitable for the gauge of the lead in use.
Route grounding conductors along the shortest possible route. Treat the bare
portion of the conductor with antioxidant and connect a listed two-hole
compression lug. If the lug is not plated, bring it to a bright finish and coat it
with antioxidant before connecting it to the rack frame. Do not mix conductors
of different types of metal.
