General Console Requirements
2-2-1 Console Environmental Requirements
2-2-1-1 Cooling
The cooling requirement for the Voluson® 730Expert is 3446 BTU/hr. This figure does not include
cooling needed for lights, people, or other equipment in the room.
NOTE: Each person in the room places an additional 300 BTU/hr. demand on the cooling system.
2-2-1-2 Lighting
Bright light is needed for system installation, updates and repairs. However, operator and patient
comfort may be optimized if the room light is subdued and indirect. Therefore a combination lighting
system (dim/bright) is recommended. Keep in mind that lighting controls and dimmers can be a source
of EMI which could degrade image quality. These controls should be selected to minimize possible
interference.
2-2-2 Electrical Requirements
NOTE: GE Healthcare requires a dedicated power and ground for the proper operation of its Ultrasound
equipment. This dedicated power shall originate at the last distribution panel before the system.
The dedicated line shall consist of one phase, a neutral (not shared with any other circuit), and a full
size Ground wire from the distribution panel to the Ultrasound outlet.
NOTE: Please note that image artifacts can occur, if at any time within the facility, the Ground from the main
facility's incoming power source to the Ultrasound unit is only a conduit.
