2-2-3 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 (not shared with any other circuit) 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 (not shared with any other circuit) 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.
2-2-4 Power Requirements
Electrical Specifications for LOGIQ™ 3.
2-2-4-1 Inrush Current
Inrush current is not a factor to consider due to inrush current limiting properties of the power supplies.
2-2-4-2 Site Circuit Breaker
It is recommended that the branch circuit breaker for the machine be ready accessible.

DANGER
POWER OUTAGE MAY OCCUR.
The LOGIQ™ 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.
