Danfoss VLT AutomationDrive Design Guide

Make the screen connections with the largest possible
surface area (cable clamp). This is done by using the
supplied installation devices within the frequency
converter.
Cable-length and cross-section:
The frequency converter has been EMC tested with a given
length of cable. Keep the motor cable as short as possible
to reduce the noise level and leakage currents.
Switching frequency:
When frequency converters are used together with Sine-
wave filters to reduce the acoustic noise from a motor, the
switching frequency must be set according to the
instruction in 14-01 Switching Frequency.
