VLTp Micro Drive FC 51 Operating Instructions
1. Safety
1.1.1. High Voltage Warning
The voltage of the frequency converter is dangerous whenever it is connected to mains. Incorrect installation of the motor or frequency
converter 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 frequency converter is properly connected to earth.
• Do not remove mains connections, motor connections or other power connections while the frequency converter is connected to power.
• Protect users against supply voltage.
• Protect the motor against overloading according to national and local regulations.
• The earth leakage current exceeds 3.5 mA.
• The [OFF] key is not a safety switch. It does not disconnect the frequency converter from mains.
1.1.3. Approvals
1. Safety
1
1.1.4. General Warning
Warning:
Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.
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.
Shorter time is allowed only if indicated on the nameplate for the specific unit.
Leakage Current
The earth leakage current from the VLT Micro Drive FC 51 exceeds 3.5 mA. According to IEC 61800-5-1 a reinforced Protective Earth
connection must be ensured by means of a min. 10mm² Cu or an addtional PE wire - with the same cable cross section as the Mains
wiring - must be terminated separately.
Residual Current Device
This product can cause a D.C. current in the protective conductor. Where a residual current device (RCD) is used for extra protection,
only an RCD of Type B (time delayed) shall be used on the supply side of this product. See also Danfoss Application Note on RCD, MN.
90.GX.YY.
Protective earthing of the VLT Micro Drive and the use of RCDs must always follow national and local regulations.
Motor overload protection is possible by setting Parameter 1-90 Motor thermal protection to the value ETR trip. For the North American
market: ETR functions provide class 20 motor overload protection, in accordance with NEC.

Installation in high altitudes:
By altitudes above 2km, please contact Danfoss Drives regarding PELV.
1.1.5. IT Mains
IT Mains
Installation on isolated mains source, i.e. IT mains.
Max. supply voltage allowed when connected to mains: 440 V.
As an option, Danfoss offers line filters for improved harmonics performance.
1.1.6. Avoid unintended Start
While the frequency converter is connected to mains, the motor can be started/stopped using digital commands, bus commands, references or via the
Local Control Panel.
• Disconnect the frequency converter from mains whenever personal safety considerations make it necessary to avoid unintended start of any
motors.
• To avoid unintended start, always activate the [OFF] key before changing parameters.
1.1.7. Disposal Instruction
tions
Equipment containing electrical components must not be disposed of together with domestic waste.
It must be separately collected with electrical and electronic waste according to local and currently valid leg-
islation.
1.1.8. Before Commencing Repair Work
1. Disconnect FC 51 from mains (and external DC supply, if present.)
2. Wait for 4 minutes for discharge of the DC-link.
3. Disconnect DC bus terminals and brake terminals (if present)
4. Remove motor cable

3.1.2. Fuses
Branch circuit protection:
In order to protect the installation against electrical and fire hazard, 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 DC-link. The frequency converter 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 A
(symmetrical), 480 V maximum.
rms
3
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 frequency converter.

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
is in EN 61800-3
Good engineering practice to ensure EMC-correct electrical installation:

First environment
is required. If the installation
• Use only braided screened/armoured motor cables and control cables.
The screen should provide a minimum coverage of 80%.The screen material must be metal, not limited to but typically copper, aluminium, steel
or lead. There are no special requirements for the mains cable.
• Installations using rigid metal conduits are not required to use screened cable, but the motor cable must be installed in conduit separate from
the control and mains cables. Full connection of the conduit from the drive to the motor is required. The EMC performance of 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 control cables.
• Avoid terminating the screen/armour with twisted ends (pigtails). Such a termination increases the high frequency impedance of the screen,
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 frequency converter, see Instruction MI.02.BX.YY
• Avoid using unscreened/unarmoured motor or control cables inside cabinets housing the drive(s), where possible.
