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
Power specification is showing in chapter 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 cable 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 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, fuses of the building’s supply circuit may be tripped.
3.1.1.3 EMI Limitation
Ultrasound machines are susceptible to Electromagnetic Interference (EMI) by radio frequencies,
magnetic fields, and transient in the air wiring. They also generate a weak electromagnetic radiation.
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.
