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 specications 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 suciently conductive shield connections.
• Connect the housing with shielding eect to the grounded mounting plate with a surface as
large as possible, e.g. of inverters and RFI lters.
• Use central earthing points.
The following example shows the eective wiring.
Low-capacitance motor cable
C-core/core/C-core/shield < 75/150pF/m≤ 2.5 mm² (≥ AWG 14)
C-core/core/C-core/shield < 150/300pF/m ≥ 4 mm² (≤ AWG 12)
Shield connection
Control connections
Shield connection for motor cable
(alternatively: shield connection on an
optional motor shield plate)
