Lenze i550 - EMC-Compliant Installation

EMC-compliant installaon
The drive system (inverter and drive) only complies with the EMC Direcve 2014/30/EU if it is installed
according to the guidelines for CE-typical drive systems.
These guidelines should also be followed in installaons requiring FCC Part 15 or ICES 001 compliance.
NOTICE
Electromagnec interferences
Product and peripheral devices may be aected during operaon.
▶
Use integrated conducve shield connecons for control lines and motor lines.
▶
Use central earthing points.

A Shield connecon for control connecons
B Control line
C EMC cable gland
D Motor cable with low capacity
E Power line
EMC-compliant installaon must be implemented with shielded motor cables of 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)
