System Installation 3-1
3 System Installation
3.1 Installation Preparations
Do not install the machine in the following locations:
Locations near heat generators
Locations with high humidity
Locations with flammable gases
3.1.1 Electrical Requirements
3.1.1.1 Requirements of Regulator
See Chapter 2.2.2 for power supply specifications. 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 grounding terminal should be connected
with a power grounding cable to ensure that protective grounding works normally. Make sure that
the protective grounding works normally.
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.
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.
