EMC-compliant installation
The drive system of inverter and drive comply with the EMC Directive 2014/30/EU if they are
installed according to the specications of CE-typical drive systems. These guidelines should
also be followed in installations requiring FCC Part 15 or ICES 001 compliance. The structure
at the installation location must support the EMC-compliant installation with shielded motor
cables.
• Please use suciently conductive shield connections.
• Connect the housing with shielding eect to the grounded mounting plate with a surface as
large as possible, e.g. of inverters and RFI lters.
• Use central earthing points.
Mains connection with multiple devices
Several inverters in close proximity can be connected to the mains using the integrated
Han-Q4/2 connectors. The mains cables are looped through from one inverter to the next via
the Han-Q4/2 connector.
