Figure 4-6 FM terminal wiring
AO2 is selected as open collector output, the wiring is the same as that of FM , as shown in
Figure 4 -6 .
FM is selected as the pulse frequency output, and the internal 24V power supply or external
power supply of the inverter can be used. The wiring is shown in Figure 4 -7 .

4.4 Installation instructions for compliance with EMC requirements
4.4.1 Correct EMC installation
The national standard GB/T12668.3 stipulates that the inverter needs to meet the requirements
of electromagnetic interference and anti-electromagnetic interference. The international standard
IEC/61800-3 (the third part of variable frequency speed regulation drive system: EMC specification
requirements and test methods) is equivalent to the national standard GB/T12668.3.
The FC100P produced by Janson Controls Technologies (Shenzhen) Co.,Limited has been
designed and tested according to the requirements of IEC/61800-3. Please follow the instructions in
this section for correct EMC installation to make it have good electromagnetic compatibility.
•
In the transmission system composed of the inverter and the motor, the inverter, the control
device, and the sensor are installed in a cabinet, and the noise emitted to the outside must be
limited at the main connection point, so EMI filters and AC reactors must be installed in the
cabinet to meet the electromagnetic compatibility requirements.
•
Considering the spatial separation of noise sources and noise receivers during the
mechanical / system design phase is the most effective measure to reduce interference, but it
