To the external potentiometer, resistance should be greater than 3kΩ and power should greater
than 1/4W. Its resistance is recommended to be 5~10kΩ.
Notice:
The terminal will use the internal circuit to adjust the input signal. To the first two work
mode, the relative internal voltage range is 0~10V. And to the third work mode, the relative
internal voltage range is 0~5V.

4.7 Installation Guidline to EMC Compliance

4.7.1 General description of EMC
EMC is the abbreviation of electromagnetic compatibility, which means the device or system has
the ability to work normally in the electromagnetic environment and will not generate any
electromagnetic interference to other equipments.
EMC includes two subjects: electromagnetic interference and electromagnetic anti-jamming.
According to the transmission mode, Electromagnetic interference can be divided into two.
categories: conducted interference and radiated interference.
Conducted interference is the interference transmitted by conductor. Therefore, any conductors
(such as wire, transmission line, inductor, capacitor and so on) are the transmission channels of
the interference.
Radiated interference is the interference transmitted in electromagnetic wave, and the energy is
inverse proportional to the square of distance.
Three necessary conditions or essentials of electromagnetic interference are: interference source,
transmission channel and sensitive receiver. For customers, the solution of EMC problem is
mainly in transmission channel because of the device attribute of disturbance source and receiver
can not be changed
