System Installation
3.1 Preparations for Installation
NOTE:
Do not install the machine in the following locations:
Locations near heat generators;
Locations of high humidity;
Locations with flammable gases.
3.1.1 Electrical Requirements
3.1.1.1 Requirement of Regulated Power Supply
Due to the difference of the power supply stability of different districts, please advise
the user to adopt a regulator of good quality and performance such as an on-line UPS.
3.1.1.2 Grounding Requirements
The power cord of the system is a three-wire cable, the protective grounding terminal
of which is connected with the grounding phase of the power supply. Please ensure that
the grounding protection of the power supply works normally.
WARNING:
DO NOT connect this system to outlets with the same
circuit breakers and fuses that control the current of
devices such as life-support systems. If this system
malfunctions and generates an over current, or when
there is an instantaneous current at power ON, the
circuit breakers and fuses of the building’s supply circuit
may be tripped.
3.1.1.3 EMI Limitation
Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio
frequencies, magnetic fields, and transient in the air wiring. They also generate EMI.
Possible EMI sources should be identified before the unit is installed.
Electrical and electronic equipment may produce EMI unintentionally as the result of
defect.
These sources include: medical lasers, scanners, monitors, cauterizing guns and so on.
Besides, other devices that may result in high frequency electromagnetic interference
such as mobile phone, radio transceiver and wireless remote control toys are not allowed
to be presented or used in the room. Turn off those devices to make sure the ultrasound
system can work in a normal way.
