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
Requirement of power supply is referring to 2.2.2.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.
