4.1.3.4.2 For U.S. only: Grounding the System
Implementation guidelines in accordance with NEC (National Electrical Code), UL 60950-1 and
IEC 60364 must be adhered to during installation.
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 lower right corner of the backplane). The minimum cross-section required is 12
AWG.
Figure 4-8 shows the safety conductor connectors for the basic cabinet. An expansion cabinet
requires a separate earth ground.
