1.1.2. 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.
1.1.3. 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.

1.1.5. 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.
1.1.6. 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.
1.1.7. 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.

1.1.8. Disposal Instruction
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.
1.1.9. 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
1.1.10. Side-by-Side Installation
The Danfoss VLT Micro Drive can be mounted side-by-side for IP 20 rating units and requires 100 mm clearance above and below for cooling. Please
refer to the specifications near the end of this document for details on environmental ratings of the VLT Micro FC 51.

1.1.13. 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 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 frequency converter.

1.1.14. Connecting to Mains and Motor
The VLT Micro FC 51 is designed to operate all standard three-phased asynchronous motors.
The VLT Micro FC 51 is designed to accept mains/motor cables with a maximum cross-section of 4 mm2 (10 AWG).
• 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.
Step 1: First, mount the earth wires to earth terminal.
Step 2: Mount mains supply to terminals L1/L, L2 and L3/N (3-phase) or
L1/L and L3/N (single-phase) and tighten.
Step 3: Connect motor to terminals U, V and W.

1.1.15. Control Terminals
All control cable terminals are located underneath the terminal cover in
front of the frequency converter. Remove the terminal cover using a
screwdriver.
Illustration 1.3: Removing terminal cover.
The illustration below shows all control terminals of the VLT Micro Drive. Applying Start (term. 18) and an analog reference (term. 53 or 60) make the
frequency converter run.

Protection and Features:
• Electronic thermal motor protection against overload.
• Temperature monitoring of the heatsink ensures that the frequency converter trips in case 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 (depending on the load).
• Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if 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
1.1.23. 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 current should be decreased.
The VLT Micro Drive FC 51 has been designed for operation at max 50 °C ambient temperature with one motor size smaller than nominal. Continuous
operation at full load at 50 °C ambient temperature will reduce the lifetime of the frequency converter.
1.1.24. Derating for Low Air Pressure
The cooling capability of air is decreased at low air pressure.
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 or the maximum output current should be decreased.
Decrease the output by 1% per 100 m altitude above 1000 m or reduce the max. ambient temperature by 1 degree per 200 m
1.1.25. Derating for Running at Low Speeds
When a motor is connected to at frequency converter, it is necessary to check that the cooling of the motor is adequate.
A problem may occur at low speeds in constant torque applications. Running continuously at low speeds – below half the nominal motor speed – may
require additional air cooling. Alternatively, choose a larger motor (one size up).
