Lenze I51AE175F - 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 interference
Product and peripheral devices may be aected during operaon.
▶
Please use suciently conducve shield connecons.
▶
Connect the housing with shielding eect to the grounded mounng plate with a surface as large as
possible, e. g., inverters and RFI lters.
▶
Use central earthing points.

A Shield connecon for control cables
B Control cable
C Mounng plate with conducve surface
D Shield connecon for motor cable
(alternavely: shield connecon on an
oponal motor shield plate)
E Motor cable with low capacity
EMC-compliant installaon 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)
