4.1.6 Screened CablesWARNINGDanfoss recommends using screened cables between theLCL filter and the frequency converter. Unshielded cablescan be used between transformer and LCL filter inputside.It is important that screened and armoured cables areconnected in a proper way to ensure high EMC immunityand low emissions.The connection can be made using either cable glandsor clamps.• EMC cable glands: Available cable glands can beused to ensure an optimum EMC connection.• EMC cable clamp: Clamps allowing easyconnection are supplied with the frequencyconverter.4.1.7 Motor CableConnect the motor to terminals U/T1/96, V/T2/97, W/T3/98.Ground to terminal 99. All types of 3-phase asynchronousstandard motors can be used with a frequency converter.The factory setting is for clockwise rotation with thefrequency converter output connected as follows:Terminal Number Function96, 97, 98 Mains U/T1, V/T2, W/T399 GroundTable 4.3 Motor Connection Terminals• Terminal U/T1/96 connected to U-phase.• Terminal V/T2/97 connected to V-phase.• Terminal W/T3/98 connected to W-phase.175HA036.11U1 V1 W196 97 98FCMotorU2 V2 W2U1 V1 W196 97 98FCMotorU2 V2 W2Illustration 4.13 Wiring for Clockwise and CounterclockwiseMotor RotationThe direction of rotation can be changed by switching 2phases in the motor cable or by changing the setting of4-10 Motor Speed Direction.A motor rotation check can be performed using 1-28 MotorRotation Check and following the steps shown on thedisplay.RequirementsF8/F9 requirements: The cables must be of equal lengthwithin 10% between the inverter module terminals and thefirst common point of a phase. The recommendedcommon point is the motor terminals.F10/F11 requirements: Motor phase cable quantities mustbe multiples of 2, resulting in 2, 4, 6, or 8 (1 cable is notallowed) to obtain equal amount of wires attached to bothinverter module terminals. The cables must be equallength within 10% between the inverter module terminalsand the first common point of a phase. The recommendedcommon point is the motor terminals.F12/F13 requirements: Motor phase cable quantities mustbe multiples of 3, resulting in 3, 6, 9, or 12 (1, 2, or 3cables are not allowed) to obtain an equal amount of wiresattached to each inverter module terminal. The wires mustbe of equal length within 10% between the inverterHow to Install Operating Instructions36 Danfoss A/S © Rev. 06/2014 All rights reserved. MG20Y20244
