    1.1.1. High Voltage Warning

    The voltage of the adjustable frequency drive is dangerous whenever it is connected to AC line power. Incorrect installation of the

    motor or adjustable frequency drive may cause damage to the equipment, serious injury or death. Consequently, it is essential to

    comply with the instructions in this manual as well as local and national rules and safety regulations.

    1.1.2. Safety Instructions

    • Make sure the adjustable frequency drive is properly grounded.

    • Do not remove line power connections, motor connections or other power connections while the adjustable frequency drive is connected to line

    power.

    • Protect users against supply voltage.

    • Protect the motor against overloading in accordance with national and local regulations.

    • The ground leakage current exceeds 3.5 mA.

    • The [OFF] key is not a safety switch. It does not disconnect the adjustable frequency drive from line power.

    1.1.3. Approvals

    1.1.4. General Warning

    Warning:

    Touching the electrical parts may be fatal - even after the equipment has been disconnected from line power.

    Also make sure that other voltage inputs have been disconnected (linkage of DC intermediate circuit).

    Be aware that there may be high voltage on the DC link even when the LEDs are turned off.

    Before touching any potentially live parts of the VLT Micro Drive, wait at least 4 minutes for all sizes.

    A shorter time is allowed only if indicated on the nameplate for the specific unit.

    Leakage Current

    The ground leakage current from the VLT Micro Drive FC 51 exceeds 3.5 mA. According to IEC 61800-5-1, a reinforced protective

    ground connection must be ensured by means of a min. of 0.016 in² [10 mm²] Cu or an additional PE wire - with the same cable cross-

    section as the line power wiring, which must be terminated separately.

    Residual Current Device

    This product can cause DC current in the protective conductor. If a residual current device (RCD) is used for extra protection, only an

    RCD of Type B (time delayed) may be used on the supply side of this product. See also Danfoss Application Note on RCD, MN.90.GX.YY.

    Protective grounding of the VLT Micro Drive and the use of RCDs must always follow national and local regulations.

    3.1.2. Fuses

    Branch circuit protection:

    In order to protect the installation against electrical and fire hazards, all branch circuits in an installation, switch gear, machines, etc. must be short-

    circuited and overcurrent protected according to national/international regulations.

    Short circuit protection:

    Danfoss recommends using the fuses mentioned in the following tables to protect service personnel or other equipment in case of an internal failure in

    the unit or short-circuit on the DC link. The adjustable frequency drive provides full short-circuit protection in case of a short-circuit on the motor or brake

    output.

    Overcurrent protection:

    Provide overload protection to avoid overheating of the cables in the installation. Overcurrent protection must always be carried out according to national

    regulations. Fuses must be designed for protection in a circuit capable of supplying a maximum of 100,000 Arms (symmetrical), 480 V maximum.

    NonUL compliance:

    If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in table 1.3, which will ensure compliance with EN50178:

    In case of malfunction, not following the fuse recommendation may result in damage to the adjustable frequency drive.

    3.1.3. EMC-correct Installation

    Following these guidelines is advised where compliance with EN 61000-6-3/4, EN 55011 or EN 61800-3 First environment is required. If the installation

    is in EN 61800-3 Second environment, then it is acceptable to deviate from these guidelines. However, it is not recommended.

    Good engineering practice to ensure EMC-correct electrical installation:

    • Use only braided shielded/armored motor cables and control cables.

    The shield should provide a minimum coverage of 80%. The shield material must be metal, not limited to but typically copper, aluminum, steel

    or lead. There are no special requirements for the line cable.

    • Installations using rigid metal conduits are not required to contain shielded cable, but the motor cable must be installed in a conduit separate

    from the control and line cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of flexible conduits

    varies greatly, and information from the manufacturer must therefore be obtained.

    • Connect the shield/armor/conduit to ground at both ends for motor cables and control cables.

    • Avoid terminating the shield/armor with twisted ends (pigtails). This type of termination increases the high frequency impedance of the shield,

    which reduces its effectiveness at high frequencies. Use low impedance cable clamps or glands instead.

    • Ensure good electrical contact between the de-coupling plate and the metal chassis of the adjustable frequency drive; see Instruction MI.

    02.BX.YY

    • Avoid using unshielded/unarmored motor or control cables inside cabinets housing the drive(s), whenever 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, and connect 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.

  • 7.2. Other Specifications

    Protection and Features:

    • Electronic thermal motor protection against overload.

    • Temperature monitoring of the heatsink ensures that the adjustable frequency drive trips in case of overtemperature

    • The adjustable frequency drive 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 line phase is missing, the adjustable frequency drive trips or issues a warning (depending on the load).

    • Monitoring of the intermediate circuit voltage ensures that the adjustable frequency drive trips if the intermediate circuit voltage is too low or

    too high.

    • The adjustable frequency drive is protected against ground faults on motor terminals U, V, W.
