2 Pay particularattention to the safety instructions and general keep this Quick Guide with the frequency is a registered ResourcesAdditional resources are available to understand advancedfrequency converter functions and programming: The VLT Micro Drive FC 51 Programming Guideprovides greater detail on working withparameters and many application examples. The VLT Micro Drive FC 51 Design Guide providesdetailed information about capabilities andfunctionality to design motor control systems. Instructions for operation with optionalequipment and replacement of publications and manuals are available #/089 The frequency converter complies with UL 508C thermalmemory retention requirements.

See Table Unintended StartWhile the frequency converter is connected to mains, themotor can be started/stopped using digital commands, buscommands, references, or via the LCP (local control panel).To avoid unintended start: Disconnect the frequency converter from mainsfor personal safety considerations. Always press [Off/Reset] before containing electrical componentsmust not be disposed of together with must be separately collected with electricaland electronic waste according to local andcurrently valid GuideVLT Micro Drive FC 512 Danfoss A/S 10/2017 All rights SafetyWARNINGHIGH VOLTAGEF requency converters contain high voltage whenconnected to AC mains input, DC supply, or load to perform installation, start-up, and maintenanceby qualified personnel can result in death or seriousinjury.

4 Only qualified personnel must perform instal-lation, start-up, and maintenance. Before performing any service or repair work,use an appropriate voltage measuring device tomake sure that there is no remaining voltage onthe STARTWhen the frequency converter is connected to AC mains,the motor may start at any time, causing risk of death,serious injury, equipment, or property damage. Themotor can start by means of an external switch, afieldbus command, an input reference signal from theLCP or LOP, or after a cleared fault condition. Disconnect the frequency converter from mainswhenever personal safety considerations makeit necessary to avoid unintended motor start.

5 Press [Off/Reset] on the LCP beforeprogramming parameters. The frequency converter , motor, and any drivenequipment must be in operational readinesswhen the frequency converter is connected toAC [Off/Reset] key is not a safety switch. It does notdisconnect the frequency converter from TIMEThe frequency converter contains DC-link capacitors,which can remain charged even when the frequencyconverter is not powered. High voltage can be presenteven when the warning LED indicator lights are to wait the specified time after power has beenremoved before performing service or repair work canresult in death or serious injury. Stop the motor. Disconnect AC mains and remote DC-link powersupplies, including battery back-ups, UPS, andDC-link connections to other frequencyconverters.

6 Disconnect or lock PM motor. Wait for the capacitors to discharge fully. Theminimum duration of waiting time is specifiedin Table Before performing any service or repair work,use an appropriate voltage measuring device tomake sure that the capacitors are waiting time (minutes)M1, M2, and M34M4 and M515 Table Discharge TimeLeakage current (> mA)Follow national and local codes regarding protectiveearthing of equipment with a leakage current >3,5 converter technology implies high frequencyswitching at high power. This generates a leakage currentin the ground connection. A fault current in the frequencyconverter at the output power terminals might contain aDC component, which can charge the filter capacitors andcause a transient ground current.

7 The ground leakagecurrent depends on various system configurationsincluding RFI filtering, screened motor cables, andfrequency converter (Power Drive System Product Standard)requires special care if the leakage current exceeds Grounding in 1 of the following ways: Grounding wire of at least 10 mm2 (8 AWG). 2 separate ground wires both complying with thedimensioning EN 60364-5-54 for further GuideQuick GuideMG02BC02 Danfoss A/S 10/2017 All rights RCDsWhere residual current devices (RCDs), also known as earthleakage circuit breakers (ELCBs), are used, comply with thefollowing: Use RCDs of type B that can detect AC and DCcurrents. Use RCDs with an inrush delay to prevent faultsdue to transient ground currents.

8 Dimension RCDs according to the system configu-ration and environmental thermal protectionMotor overload protection is possible by setting parameter1-90 Motor Thermal Protection to [4] ETR trip. For the NorthAmerican market: Implemented ETR function provides class20 motor overload protection, in accordance with at high altitudesFor altitudes above 2000 m (6562 ft), contact Danfossregarding Instructions Make sure that the frequency converter isproperly grounded. Do not remove mains connections, motorconnections, or other power connections whilethe frequency converter is connected to power. Protect users against supply voltage. Protect the motor against overloading accordingto national and local regulations.

9 The ground leakage current exceeds the frequency converter properly. The [Off/Reset] key is not a safety switch. It doesnot disconnect the frequency converter the VLT Micro Drive FC 51 frommains (and external DC supply, if present). for 4 minutes (M1, M2, and M3) and 15minutes (M4 and M5) for discharge of the Table the DC bus terminals and the braketerminals (if present). the motor InstallationThe frequency converter can be mounted side by side forIP20 rating units and requires 100 mm ( in) clearanceabove and below for cooling.
