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:
