Chapter 9 EMC
9.1 EMC–Correct Installation
HLP-B serials drive implement the latest international standards,
following these guidelines is advised, IEC/EN61800-3:2004 (Adjustable speed
electrical power drive systems part 3: EMC requirements and specif ic test
methods). In order to achieve the using requirements of the EMC, must meet
the following speci
fi
cations:
●
Using shield motor cables, and connect it to the decoupling device
(optional) and the metal motor cabinet;
●
To reduce the noise and the leakage current, use the motor cable as short
as possible;
●
The entire system need to have a good earthling;
●
RFI Switch screw must be tightened up.
9.2 RFI Switch
Use the RFI switch screw to remove the internal EMC f ilter, if the
f requency converter is supplied f rom IT or TN Grid. If a drive with EMC
fi
lter is connected to the IT grid, then the system may be grounded through the
EMC
fi
lter capacitors, this may cause damage to the inverter. If a drive with
EMC
fi
lter is connected to the TN grid, the drive may be burned. Remove the
RFI switch can help to reduce the leakage currents.
Step1: Open a hole in line with the size of the
control panel in the position need to install
the LCP, hole size, as shown:
Step 3: The LCP is installed in the cradle,
according to the direction of the arrow.
Step 4: Install the external LCP communication
cable, insert into RJ45 terminal from thebottom
of hole.
Recommended
to install vertical

Press and hold
the snap roots when
installation, using
buckle deformation
install sheet metal.
Step2: Install the LCP according to
the direction of the arrow.
