SX-2000 VS Grounding 
The SX-2000 VS systems operating in North America require only one external 
ground, the safety ground. A ground clip, attached to the EMI shield, links the safety 
ground to the system ground on the System Filter Assembly Card. 
The System Filter Assembly card, plugged into the backplane, provides a common 
point for all grounds in the system (DGI). 
Refer to Figure 1-I 3 for ground references on the SX-2000 VS system. 
Grounding cables are to be installed in accordance with the information that is listed 
in Table I-5.

SX-2000 FD Grounding 
The SX-2000 FD systems operating in North America require only one external 
ground, the system ground. 
Refer to Figure 1-14 for ground references on the SX-2000 FD system. A 14 AWG 
gauge system ground cable is installed between the system ground terminal on the 
backplate of each Peripheral Node and the site building ground. 
Grounding cables are to be installed in accordance with the information listed in table 
Table 1-S.
