1.5 Approvals and CertificationsIllustration 1.4 CEThe VLT® Plus Panel carries a CE mark in accordance withthe Low Voltage Directive 2006/95/EC and EMC Directive2004/108/EC of the European Union.The frequency converter complies with UL 508C thermalmemory retention requirements. For more information,refer to the section Motor Thermal Protection in theproduct-specific design guide.NOTICEImposed limitations on the output frequency(due to export control regulations):From software version 6.72 onwards, the outputfrequency of the frequency converter is limited to 590Hz. Software versions 6.xx also limit the maximumoutput frequency to 590 Hz, but these versions cannotbe flashed, that is, neither downgraded nor upgraded.1.6 DisposalDo not dispose of equipment containingelectrical components together withdomestic waste.Collect it separately in accordance withlocal and currently valid legislation.1.7 Symbols, Abbreviations, andConventionsAbbreviation DefinitionAC Alternating currentAMA Automatic motor adaptationAVM Asynchronous vector modulationDC Direct currentDE Drive-endELCB Earth (ground) leakage circuit breakerEMC Electromagnetic compatibilityEMI Electromagnetic interferenceHO High overloadIGBT Insulated-gate bipolar transistorLCP Local control panelLED Light-emitting diodeNED Non-drive endNO Normal overloadRCD Residual current deviceRDF Rated diversity factor according to DIN EN61439RFI Radio-frequency interference, see EMISFAVM Stator flux-oriented asynchronous vectormodulationSTO Safe Torque OffUPS Uninterruptible power supplyTable 1.2 Symbols and AbbreviationsConventionsNumbered lists indicate procedures.Bullet lists indicate other information and description ofillustrations.Italicized text indicates:• Cross-reference.• Link.• Footnote.• Parameter name.• Parameter group name.• Parameter option.Introduction Installation GuideMG13B102 Danfoss A/S © 09/2015 All rights reserved. 71 1
