Divide the installation space into different areas
In driving system, the drive, control equipment and
sensors are installed in the same cabinet, the noise
should be suppressed at the main connecting points
with the RFI filter and input reactor installed in cabinet to
satisfy the EMC requirements.
The most effective but expensive measure to reduce the
interference is to ***late the noise source and the noise
receiver, which should be considered in
mechanical/system design phase. In driving system, the
noise source can be drive, brake unit and contactor.
Noise receiver can be automation equipment, coder and
sensor.
The mechanical/system is divided into different EMC
area according to its electrical characteristics. The
recommended installation positions are shown in the
following figure:

Fig. 3-43 Recommendation of Installation space
Attention:
· Area Ⅰshould be used to install transformers of
control power supply, control system and sensor.
·Area Ⅱ should be used for interfaces of signal and
control cables, correct immunity level is required.
· Area Ⅲ should be used to install noise sources such
as input reactor, the drive, brake unit and contactor.
·Area Ⅳ should be used to install output noise filter
and the wires of filter.
·Area Ⅴ should be used to install power source and
cable connecting parts of RFI filter.
·Area Ⅵ should be used to install motor and motor
cables.
·Areas should be ***lated in space, so that
electro-magnetic decoupling effect can be achieved.
·The minimum distance between areas should be 20cm.
·Earthing bars should be used for decoupling among
areas, the cables from different area should be placed in
different tubes.
·The filter should be installed at the interfaces between
different areas if necessary.
·Bus cable(such as RS485) and signal cable must be
shielded

Fig. 3-44 Installation of the drive
·Motor cable should be earthed at the drive side, if
possible, the motor and drive should be earthed
separately;
·Motor cable and control cable should be shielded or
armored. The shield must be earthed and avoid
entangling at cable end to improve high frequency noise
immunity.
·Assure good conductivity among plates, screw and
metal case of the drive; use tooth-shape washer and
conductive installation plate;
Generally, if there are some sensitive equipment, it is
more cost-effective to install the power filter at sensitive
equipment side.
3.4.7 Application of Power Line Filter
Power source filter should be used in the equipment that
may generate strong EMI or the equipment that is
sensitive to the external EMI. The power source filter
should be a two-way low pass filter through which only
50Hz current can flow and high frequency current should
be rejected.
Function of power line filter
The power line filter ensures the equipment can satisfy
the conducting emission and conducting sensitivity in
EMC standard. It can also suppress the radiation of the
equipment.
