Unshielded cables can bebetween transformer and LCL filter input side.It is important that shielded and armoured cables areconnected in a proper way to ensure the high EMCimmunity and low emissions.The connection can be made using either cable glandsor clamps• EMC cable glands: Generally available cableglands can be used to ensure an optimum EMCconnection.• EMC cable clamp: Clamps allowing easyconnection are supplied with the frequencyconverter.3.6.7 Motor CableThe motor must be connected to terminals U/T1/96, V/T2/97, W/T3/98. Earth to terminal 99. All types of 3-phaseasynchronous standard motors can be used with afrequency converter unit. The factory setting is forclockwise rotation with the frequency converter outputconnected as follows:Terminal No. Function96, 97, 98, 99 Mains U/T1, V/T2, W/T3EarthTable 3.21 Mains Terminals• Terminal U/T1/96 connectedto U-phase• Terminal V/T2/97 connectedto V-phase• Terminal W/T3/98connected to W-phase175HA036.11U1 V1 W196 97 98FCMotorU2 V2 W2U1 V1 W196 97 98FCMotorU2 V2 W2Table 3.22The direction of rotation can be changed by switching 2 phases inthe motor cable or by changing the setting of 4-10 Motor SpeedDirection.Motor rotation check can be performed using 1-28 MotorRotation Check and following the steps shown in thedisplay.F enclosure requirementsF1/F3 requirements: Motor phase cable quantities must bemultiples 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 are required to beequal length within 10% between the inverter moduleterminals and the first common point of a phase. Therecommended common point is the motor terminals.F2/F4 requirements: Motor phase cable quantities must bemultiples of 3, resulting in 3, 6, 9, or 12 (1 or 2 cables arenot allowed) to obtain equal amount of wires attached toeach inverter module terminal. The wires are required tobe equal length within 10% between the inverter moduleterminals and the first common point of a phase. Therecommended common point is the motor terminals.Output junction box requirements: The length, minimum2.5 m, and quantity of cables must be equal from eachinverter module to the common terminal in the junctionbox.NOTICEIf a retrofit application requires unequal amount of wiresper phase, consult the factory for requirements anddocumentation or use the top/bottom entry side cabinetoption.How to Install VLT AQUA Drive FC 202 Operation Instructions54 MG20P402 - Rev. 2013-12-1633
