Installing the system ground

Note: Use the grounding block as a bridging point for ground
wires from:

•

up to three nearby Cabinet systems. If you have remote
cabinets, or when more than three cabinets are collocated,
you require additional grounding blocks.

•

up to six nearby chassis and chassis expander pairs. If you
have additional chassis, you require additional grounding
blocks.

For the Cabinet system: Install a #6 AWG (#40 Metric Wire Gauge)
ground wire from the ground lug in each cabinet to the NTBK80
grounding block.

Connect the ground wire to the ground lug located in the bottom
portion of the cabinet next to the cable connectors. Route the
ground wire through the third groove from the left in the bottom of
the cabinet. See

Figure 55 "Ground/Earth lug in the NTAK11 system

cabinets" (page 131)

Connect the ground wire to the grounding block. See

Figure 57

"NTBK80 grounding block" (page 133)

Place a DO NOT DISCONNECT tag on the ground wire.
