Site Preparation

2.1 General Requirements

2.1.1 Environmental requirements

Operating Temperature
10 to 30°C
(50 to 86°F)
Caution
If the system has been in storage, has been transported or is very cold or hot, do not turn on its power until it
has had a chance to acclimate to its operating environment. (see:
page 3-2
).
2.1.1.1 Cooling
The cooling requirement for a Voluson E-Series system is 2730 BTU/hour. 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.
Note
2.1.1.2 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.

2.1.2 Electrical Requirements

GE Healthcare Austria GmbH & Co OG requires a dedicated power and ground for the proper operation of
Note
its Ultrasound equipment. This dedicated power shall originate at the last distribution panel before the
system.
The Ultrasound will function on voltages from 100-240 Volts and 50 or 60 Hz. However, if using 220 volt
power in North America, then a center tapped power source is required.
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 system is only a conduit.
2.1.2.1 Voluson Power Requirements Voluson E-Series
Voltage
100 - 240 VAC
AC mains power outlets (AUX) for auxiliary devices and peripherals are co-switched by the systems mains
switch. Output voltage for AUX: 115V
Caution
The maximum power consumption of equipment (inclusive color LCD monitor) connected to these outlets
must not exceed 200VA!
