Ground System
The BrightSpeed CT Scanner has been designed to use an equal potential grounding system. The
required ground system is shown in
Figure 8-1 . There are three primary grounding points:
• A system power ground point located in the PDU.
• A reference ground point located between gantry and table base.
• A patient ground point located at the front of the table base.
All exposed metal surfaces in the patient vicinity are grounded to the reference ground point.
For additional information, refer to Electrical Safety Equipment, Direction 46-014505.
