Chapter 2 - Pre-Installation 2-3
2-2-5 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.
2-2-5-1 Vivid™ 4 Power Requirements
Electrical specifications for the Vivid™ 4 monitor and onboard peripherals are as follows:
2-2-5-2 Inrush Current
Inrush current is not a factor for consideration, due to the inrush current limiting properties of the power
supplies.
Maximum power requirement = 1.2 KVa
• 100V AC: 8A
• 120V AC: 8A
• 220 - 240V AC: 4A
2-2-5-3 Site Circuit Breaker
It is recommended that the branch circuit breaker for the machine be readily accessible.
Table 2-3 Electrical Requirements
Voltage Tolerances Op. Current Frequency
100V AC ±10% 8A 50-60 Hz
120V AC ±10% 8A 50-60 Hz
220 - 240V AC ±10% 4A 50-60 Hz
CAUTION
POWER OUTAGE MAY OCCUR.
The Vivid 3 requires a dedicated single branch circuit. To avoid circuit overload and possible
loss of critical care equipment, make sure you DO NOT have any other equipment operating on
the same circuit.
