5.3 Grounding
The system has been designed to use an equal potential grounding system. The required ground
system is shown in Figure 5-1: D670 System Grounding Map, p.5-8.
The system includes 3 primary grounding points:
 System power ground point, located in the PDU
 NM Reference ground point, located at the side of the NM gantry base
 CT Reference ground point, located at the front of the CT gantry base
All exposed metal surfaces in the patient vicinity are grounded to the reference ground point.
