2.1.2.2 Inrush Current
Inrush current is not a factor to consider due to the inrush current limiting properties of the power supplies.
2.1.2.3 Site Circuit Breaker
It is recommended that the branch circuit breaker for the system be readily accessible.
Caution: Power outage may occur.
Voluson E-Series 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.
2.1.2.4 Site Power Outlets
A dedicated AC power outlet must be within reach of the system without extension cords. Other outlets
adequate for the external peripherals, medical and test equipment needed to support this system must also
be present within 1 m (3.2 ft.) of the system. Electrical installation must meet all current local, state, and
national electrical codes.
2.1.2.5 System Power Plug
If the Voluson E-Series arrives without a power plug, or with the wrong plug, you must contact your GE
dealer or the installation engineer must supply what is locally required.
2.1.3 EMI Limitations
Ultrasound systems are susceptible to Electromagnetic Interference (EMI) from radio frequencies, magnetic
fields, and transients in the air or wiring. They also generate EMI. The Voluson E-Series system complies
with limits as stated on the EMC label. However, there is no guarantee that interference will not occur in a
particular installation.
Note
Possible EMI sources should be identified before the system is installed.
Electrical and electronic equipment may produce EMI unintentionally as the result of a defect. Sources of
EMI include the following:
•
medical lasers
•
scanners
•
cauterizing guns
•
computers
•
monitors
•
fans
•
gel warmers
•
microwave oven
•
light dimmers
•
mobile phones
•
in-house wireless phones (DECT phones)
•
wireless computer keyboard and mouse
•
air conditioning system
•
High Frequency (HF) surgery equipment
•
general AC/DC adapters
The presence of a broadcast station or broadcast van may also cause interference.
