5.3.3 Connection to Mains and EarthingNOTEThe plug connector for power can be removed.1. Make sure that the frequency converter isproperly earthed. Connect to earth connection(terminal 95). Use screw from the accessory bag.2. Place plug connector 91, 92, 93 from theaccessory bag onto the terminals labelled MAINSat the bottom of the frequency converter.3. Connect mains wires to the mains plugconnector.CAUTIONThe earth connection cable cross section must be at least10 mm2 or 2 rated mains wires terminated separatelyaccording to EN 50178.The mains connection is fitted to the main switch ifincluded.NOTECheck that mains voltage corresponds to the mainsvoltage of the frequency converter name plate.CAUTIONIT MainsDo not connect 400 V frequency converters with RFI-filtersto mains supplies with a voltage between phase and earthof more than 440 V.For IT mains and delta earth (grounded leg), mains voltagecan exceed 440 V between phase and earth.3 Phasepowerinput130BA026.1091 (L1)92 (L2)93 (L3)95 PEIllustration 5.44 Terminals for Mains and Earthing5.3.4 Motor Cable ConnectionNOTEScreened motor cable is recommended. If an unscreenedcable is used, some EMC requirements are not compliedwith. For more information, see 5.10 EMC-correct Instal-lation.1. Fasten de-coupling plate to the bottom of thefrequency converter with screws and washersfrom the accessory bag.2. Attach motor cable to terminals 96 (U), 97 (V), 98(W).3. Connect to earth connection (terminal 99) on de-coupling plate with screws from the accessorybag.4. Insert terminals 96 (U), 97 (V), 98 (W) and motorcable to terminals labelled MOTOR.5. Fasten screened cable to de-coupling plate withscrews and washers from the accessory bag.All types of three-phase asynchronous standard motors canbe connected to the frequency converter. Normally, smallmotors are star-connected (230/400 V, D/Y). Large motorsare delta-connected (400/690 V, D/Y). Refer to the motorname plate for correct connection mode and voltage.U V W175ZA114.10VU W96 97 98 96 97 98Illustration 5.45 Motor Cable ConnectionNOTEIf motors are not inverter-duty rated, fit a Sine-wave filteron the output of the frequency converter.How to Install VLT® AQUA Drive FC 202 Design GuideMG20Z102 - VLT® is a registered Danfoss trademark 1015 5
