Emv-Gerechte Installation - Lenze i550 Series Mounting Instructions

EMV-gerechte Installation

The drive system of inverter and drive meet the EMC Directive 2014/30/EU, if they are installed according to
the guidelines of CE-typical drive systems.
These guidelines should also be followed in installations requiring FCC Part 15 or ICES 001 compliance.
The structure of the installation place must support the EMC-compliant installation with shielded motor
cables.
• Use sufficiently conductive shield connections.
• Connect the housing with shielding effect to the grounded mounting plate with a surface as large as
possible, e.g. of inverters and RFI filters.
• Use central earthing points.
The following example shows the effective wiring:
A Shield connection for control connections
B Control cable
C EMC cable gland
D Low-capacitance motor cable
(C-core/core/C-core/shield:
< 75/150 pF/m ≤ 2.5 mm² (≥ AWG 14)
< 150/300 pF/m ≥ 4 mm² (≤ AWG 12)
