3. Installations and Wiring
3.1 Installation Guidelines
1) Ensure the surrounding ambient operating temperature is between 0~50
℃
.
2) Ensure the power supply for the unit does not fluctuate greatly.
3) Install the unit where there is no dust, corrosive or explosive gas present.
4) Install the unit where there is no risk of mechanical vibration or shock.
5) Keep the unit away from susceptible instruments by high current and voltage circuits.
The unit and connection wires (esp. medical instruments, controller and measurement
instruments or computers) should be kept approximately 30cm (12”) away from
susceptible instruments by high current and voltage circuits to limit the possible affects of
noise.
3.2 Wiring
1) Power
Prior to applying power, ensure the supply voltage is connected to the correct terminals as
ordered specification or marked on the electrical connection diagram. Connect the power
supply voltage to input line terminals.
Tighten the power connections correctly. Poor tightening can lead to incorrect operation of the
unit and can have serious consequences on the installation. All capacity is necessary to
connect the power cables using round lugs. See table 1.
Note) Keep the connection line does not shifting R, S and T.
