Connecting inverters in compliance with EMC
4.5.1
EMC-compliant connection of the converter
EMC-compliant installation of the inverter and motor are required in order to ensure
disturbance-free operation of the drive.
Install and operate inverters with IP20 degree of protection in a closed control cabinet.
Inverters with degree of protection IP55 are suitable for installation outside a control cabinet.
An overview of control cabinet installation and cabling can be found in the following section.
For further details, refer to the installation instructions of the Power Module.
The EMC-compliant connection of the inverter itself is described in the following sections.
4.5.2
Avoiding electromagnetic influence (EMI)
The inverters are designed for operation in industrial environments where high values of EMI
are expected. Safe, reliable and disturbance-free operation is only guaranteed if the devices
are installed by appropriately trained and qualified personnel.
Control cabinet design
● Connect the metallic parts and components of the control cabinet to the frame of the
cabinet through a good electrical connection.
– Side panels
– Rear panels
– Cover plate
– Base plates
Use the largest possible contact area or many individual screw connections.
● Connect the PE busbar and EMC shielding bus to the control cabinet frame using a good
electrical connection established through the largest possible surface area.
● Connect all metal enclosures of the devices installed in the control cabinet (such as the
inverter and line filter) to the control cabinet frame through a good electrical connection
established through the largest possible surface area.
We recommend that these devices are mounted on a bare metal plate with good
conducting properties.
