Installing the converter in compliance with EMC rules
Rules for cable installation to ensure EMC
● Install the inverter on a metal mounting plate. The mounting plate must be unpainted and
highly electrically conductive.
● Use shielded cables for the following connections:
– Motor and motor temperature sensor
– Braking resistor (not available for all inverters)
– Fieldbus
– Inputs and outputs of the terminal strip
● Connect the cable shields to ensure EMC:
