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
1.1.4. General Warning
Warning:
Touching the electrical parts may be fatal - even after the equipment has been dis-
connected 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 de-
layed) 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 pro-
tection 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
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 legislation.

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. Programming
3.1. How to Programme
3.1.1. Programming with MCT-10
The frequency converter can be programmed from a PC via RS485 com-port by installing the
MCT-10 Set-up Software.
This software can either be ordered using code number 130B1000 or downloaded from the Dan-
foss Web site: www.danfoss.com, Business Area: Motion Controls.
Please refer to manual MG.10.RX.YY.
3.1.2. Programming with LCP 11 or LCP 12
The LCP is divided into four functional groups:
1. Numeric display.
2. Menu key.
3. Navigation keys.
4. Operation keys and indicator lights (LEDs).
Illustration 3.1: LCP 12 with potentiometer Illustration 3.2: LCP 11 without potentiometer
The display:
A number of information can be read from the display.
Set-up number shows the active set-up and
the edit set-up. If the same set-up acts as
both active and edit set-up, only that set-up
number is shown (factory setting).
When active and edit set-up differ, both num-
bers are shown in the display (Setup 12). The
number flashing, indicates the edit set-up.
