Section 2-2
General Console Requirements
2-2-1 Console Environmental Requirements
2-2-1-1 Cooling
The cooling requirement for the LOGIQ™ 9 is 3500 BTU/hr. This figure does not include cooling needed
for lights, people, or other equipment in the room. 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 Medical Systems 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.
Sites with a mains power system with defined Neutral and Live:
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.
Sites with a mains power system without a defined Neutral:
The dedicated line shall consist of one phase (two lines), 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.
2-2-2-1 LOGIQ™ 9 Power Requirements
2-2-2-2 Inrush Current
Inrush current is not a factor to consider due to the inrush current limiting properties of the power
supplies.
