A grounding kit provides special equipment grounding for the Expedio 500D Table
and the Intelligent Digital Device during procedures where the patient may
become susceptible to electrical shock. When installed, voltage differences due to
leakage current between various parts of the table and other properly grounded
equipment are minimized. The kit limits voltage differences should an electrical
fault occur.
Patient vicinity grounding is required for procedures such as cardiac
catheterization, in which the patient is electrically susceptible.
For patient grounding to be effective, it is imperative to properly
ground all equipment which may come in contact with the patient, or
anyone touching the patient during a procedure.
The grounding outlet panel is located on the Precision 500D table base. This
panel has connections for grounding the Precision 500D table top and other
equipment such as a film changer and injector. The panel has four green ground-
ing receptacles that accept grounding cord locking plugs.
Three grounding cables are supplied: one for the grounding table top, and two for
the grounding accessories.
The table top grounding cable has locking pin plugs at both ends. This cable con-
nects between one of the table base grounding receptacles and one of the table
top grounding receptacles.
The accessory grounding cables are terminated with a locking pin plug at one end
and a ground lug at the other end. These cables connect accessory equipment to
the table base receptacles.
To minimize the possibility of table top cable interference with patient,
personnel, or equipment, carefully consider:
1. Direction and distance that table top will be extended
2. Placement of personnel
3. Placement of equipment for the intended procedure
Check all the table motions required for the procedure, with all ground
cords, equipment, and personnel in place BEFORE bringing a patient
into an examination room.
To connect a locking pin grounding cable to a ground receptacle, press the plug
into the receptacle and rotate the plug slightly clockwise. The plug will remain
engaged in the receptacle if properly connected.
To remove locking pins, push the plug in slightly and rotate counterclockwise until
the plug is disengaged. A spring will push the plug out of the receptacle.
