2 Failure to performinstallation, start-up, and maintenance by qualifiedpersonnel could result in death or serious injury. Installation, start-up, and maintenance must beperformed by qualified personnel 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, a serialbus command, an input reference signal from the LCP orLOP, or after a cleared fault the frequency converter from mainswhenever personal safety considerations makeit necessary to avoid unintended motor [Off/Reset] on the LCP, beforeprogramming frequency converter, motor, and any drivenequipment must be in operational readinesswhen the frequency converter is connected toAC TIMEThe frequency converter contains DC-link capacitors,which can remain charged even when the frequencyconverter is not powered.

3 Failure to wait the specifiedtime after power has been removed before performingservice or repair work, could result in death or AC mains, permanent magnet typemotors, and remote DC-link power supplies,including battery back-ups, UPS, and DC-linkconnections to other frequency for the capacitors to discharge fully, beforeperforming any service or repair work. Theduration of waiting time is specified inTable waiting time [min]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.

4 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. The earth 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 3,5 grounding must be reinforced in one of thefollowing ways: earth ground wire of at least 10 mm2. Two separate ground wires both complying withthe dimensioning EN 60364-5-54 for further RCDsWhere residual current devices (RCDs), also known as earthleakage circuit breakers (ELCBs), are used, comply with thefollowing: RCDs of type B only which are capable ofdetecting AC and DC RCDs with an inrush delay to prevent faultsdue to transient earth 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.

Instructions Make sure the frequency converter is properlyconnected to earth . 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. The earth leakage current exceeds mA. The [Off/Reset] key is not a safety switch.
