Both the harmonic distortion of Danfossadjustable frequency drives as well as non-Danfossadjustable frequency drives with additional harmonicreduction devices, such as Danfoss AHF filters and12-18-pulse rectifiers, can be calculated.Ordering number:Order the CD containing the MCT 31 PC tool using codenumber 130B1031.MCT 31 can also be downloaded from www.danfoss.com/BusinessAreas/DrivesSolutions/Softwaredownload/.6.7 Safety6.7.1 High Voltage TestCarry out a high voltage test by short-circuiting terminalsU, V, W, L1, L2 and L3. Energize maximum 2.15 kV DC for380–500 V adjustable frequency drives and 2.525 kV DC for525–690 V adjustable frequency drives for one secondbetween this short-circuit and the chassis.WARNINGWhen running high voltage tests of the entire instal-lation, interrupt line power and the motor connection ifthe leakage currents are too high.6.7.2 GroundingThe following basic issues need to be considered wheninstalling an adjustable frequency drive, so as to obtainelectromagnetic compatibility (EMC).• Safety grounding: The adjustable frequency drivehas a high leakage current and must begrounded appropriately for safety reasons. Applylocal safety regulations.• High-frequency grounding: Keep the ground wireconnections as short as possible.Electrical Installation Design GuideMG11BC22 Danfoss A/S © Rev. 06/2014 All rights reserved. 1276 6
