Installation of the temperature detector
•
Firstly, daub heat conductive silicone onto the front of the temperature sensor, then insert it into the
temperature detector.
•
Next, push the temperature sensor with the pin through to the end of the temperature detector, then
mark the level of the pin on the temperature detector.
•
Finally, seal the inlet of the temperature detector with silicone to keep the ambient air isolated so it
does not a
ff
ect the reading of the sensor.
Electrical wiring
•
The unit should use dedicated power supply with supply voltage and current corresponding with rated
specification on the technical label.
•
The power cable of the unit must support the maximum starting current requirements.
•
The unit power supply circuit must have a grounding wire, which should connect with a reliable and
e
ff
ective external ground wire
•
Wiring must be installed by qualified technicians with reference to the circuit diagram.
•
The layout of power lines and signal lines should be neat, rational and strong with weak lines
separated so they cannot interfere with each other.
•
When power lines and control lines are parallel, the wires must be placed inside an insulating tube,
with appropriate distance between the lines.
•
For electrical connection of the unit, take the following wiring through the wiring hole set into the
electrical box, then connect to the appropriate terminals in the electrical box according to wiring
