Emc-Compliant Installation - Lenze i510 Mounting And Switch-On Instructions

Electrical installation

EMC-compliant installation

EMC-compliant installation
The drive system (inverter and drive) only complies with the EMC Directive 2014/30/EU if it is installed
according to the guidelines for CE-typical drive systems.
These guidelines should also be followed in installations requiring FCC Part 15 or ICES 001 compliance.
NOTICE
Electromagnetic interference
Product and peripheral devices may be affected during operation.
▶ Please 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., inverters and RFI filters.
▶ Use central earthing points.
The example below shows the effective wiring:
A Shield connection for control cables
B Control cable
C Mounting plate with conductive surface
EMC-compliant installation must be implemented with shielded motor cables with low capacitance.
Capacitance per unit length:
• C-core-core/C-core-shielding: < 75/150 pF/m ≤ 2.5 mm² (≥ AWG 14)
• C-core-core/C-core-shielding: < 150/300 pF/m ≥ 4 mm² (≤ AWG 12)
