2-2-2 Electrical Requirements
2-2-2-1 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 Line:
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.
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.
2-2-2-2 LOGIQ™ 7 Power Requirements
The following power line parameters should be monitored for one week before installation. We
recommend that you use an analyzer Dranetz Model 606-3 or Dranetz Model 626:
2-2-2-3 Inrush Current
Inrush Current is not a factor to consider due to the inrush current limiting properties of the power
supplies.
2-2-2-4 Site Circuit Breaker
It is recommended that the branch circuit breaker for the machine be ready accessible.

CAUTION
POWER OUTAGE MAY OCCURE. The LOGIQ™ 7 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.
