Figure 8.8 Preventing Induced Noise
Reducing Radiated/Radio Frequency Noise
The drive, input lines, and output lines generate radio frequency noise. Use noise filters on input and output sides and
install the drive in a metal enclosure panel to reduce radio frequency noise.
Note:
The cable running between the drive and motor should be as short as possible.

EMC Filter Installation
This drive is tested according to European standards EN61800-3 and it complies with the EMC guidelines.
Refer to EMC
Filter Installation on page 383
for details about EMC filter selection and installation.

Installing a Motor Thermal Overload (oL) Relay on the Drive Output
Motor thermal overload relays protect the motor by disconnecting power lines to the motor due to a motor overload
condition.
Install a motor thermal overload relay between the drive and motor:
