3.1.3. EMC-Correct Installation
Following these guidelines is advised, where compliance with EN 61000-6-3/4, EN 55011 or EN61800-3 First environment is required. If the installation is in EN 61800-3 Second environment,then it is acceptable to deviate from these guidelines. It is however not recommended.
Good engineering practice to ensure EMC-correct electrical installation:
• Use only braided screened/armoured motor cables and control cables.The screen should provide a minimum coverage of 80%.The screen material must bemetal, not limited to but typically copper, aluminium, steel or lead. There are no specialrequirements for the mains cable.
• Installations using rigid metal conduits are not required to use screened cable, but themotor cable must be installed in conduit separate from the control and mains cables. Fullconnection of the conduit from the drive to the motor is required. The EMC performanceof flexible conduits varies a lot and information from the manufacturer must be obtained.
• Connect the screen/armour/conduit to earth at both ends for motor cables and controlcables.
• Avoid terminating the screen/armour with twisted ends (pigtails). Such a terminationincreases the high frequency impedance of the screen, which reduces its effectivenessat high frequencies. Use low impedance cable clamps or glands instead.
• Ensure good electrical contact between the de-coupling plate and the metal chassis ofthe frequency converter, see Instruction MI.02.BX.YY
• Avoid using unscreened/unarmoured motor or control cables inside cabinets housing thedrive(s), where possible.

3.3. Motor Connection
3.3.1. How to Connect the Motor
See the chapter Specifications for correct dimensioning of motor cable cross-section and length.
• Use a shielded/armored motor cable to comply with EMC emission specifications, andconnect this cable to both the decoupling plate and the motor metal.
• Keep motor cable as short as possible to reduce the noise level and leakage currents.
For further details on mounting of the decoupling plate, please see instruction MI.02.BX.YY.
All types of three-phased asynchronousstandard motors can be connected to the fre-quency converter. Normally, small motors arestar-connected (230/400 V, Δ/Y). Large mo-tors are delta-connected (400/690 V, Δ/Y).Refer to motor nameplate for correct connec-tion and voltage.

Protection and Features:
• Electronic thermal motor protection against overload.
• Temperature monitoring of the heatsink ensures that the frequency converter trips incase of overtemperature
• The frequency converter is protected against short-circuits on motor terminals U, V, W.
• If a motor phase is missing, the frequency trips and issues an alarm.
• If a mains phase is missing, the frequency converter trips or issues a warning (dependingon the load).
• Monitoring of the intermediate circuit voltage ensures that the frequency converter tripsif the intermediate circuit voltage is too low or too high.
• The frequency converter is protected against earth faults on motor terminals U, V, W.

See section on special conditions
7.3. Special Conditions
7.3.1. The Purpose of Derating
Derating must be taken into account when using the frequency converter at low air pressure(heights), at low speeds or at high ambient temperature. The required action is described in thissection.
7.3.2. Derating for Ambient Temperature
The ambient temperature measured over 24 hours should be at least 5 °C lower than the max.ambient temperature.
If the frequency converter is operated at high ambient temperature, the continuous output currentshould be decreased.
The VLT Micro Drive FC 51 has been designed for operation at max 50 °C ambient temperaturewith one motor size smaller than nominal. Continuous operation at full load at 50 °C ambienttemperature will reduce the lifetime of the frequency converter.
7.3.3. Derating for Low Air Pressure
The cooling capability of air is decreased at low air pressure.
VLT Micro Drive FC 51 Operating Instructions 7. Specifications
MG.02.A2.02 - VLT® is a registered Danfoss trademark 33
7
For altitudes above 2000 m, please contact Danfoss Drives regarding PELV.
Below 1000 m altitude no de-rating is necessary but above 1000 m the ambient temperature orthe maximum output current should be decreased.Decrease the output by 1% per 100 m altitude above 1000 m or reduce the max. ambient tem-perature by 1 degree per 200 m
7.3.4. Derating for Running at Low Speeds
When a motor is connected to at frequency converter, it is necessary to check that the cooling ofthe motor is adequate.A problem may occur at low speeds in constant torque applications. Running continuously at lowspeeds – below half the nominal motor speed – may require additional air cooling. Alternatively,choose a larger motor (one size up).
