4.3.3.5.2 For U.S. only: Grounding the System
A connecting cable is used for grounding the system cabinets. The system must also be
grounded by a separate ground conductor. Choose a ground connection with less than 2 ohms
of resistance, such as:
● Master ground busbar
● Ground field
● Copper ground rod
Run a separate earth ground conductor from the earth ground to the cabinet frame ground (lo-
cated in the center of the bottom of the backplane). The minimum cross-section required is
12 AWG.
Figure 4-63 shows the safety conductor connectors for the basic cabinet
If one or two ECs are required in addition to the BC in a standalone system, the four metal con-
necting plates must be installed to properly ground these cabinets.
If two system cabinets are mounted on the wall, a separate grounding connector is also re-
quired for the expansion cabinet. Do not use the metal connecting plates on wall-mounted sys-
tems.
