1 Quick Guide
1.1 Safety
1.1.1 Warnings
WARNING
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.
WARNING
Electrical Hazard
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 frequency converter, wait at least as stated in the table
below:
Voltage (V) Power range (kW) Min. waiting time
(minutes)
3 x 200 0.25 – 3.7 4
3 x 200 5.5 – 11 15
3 x 400 0.37 – 7.5 4
3 x 400 11 – 90 15
3 x 600 2.2 – 7.5 4
3 x 600 11 – 90 15
CAUTION
Leakage Current:
The earth leakage current from the frequency converter
exceeds 3.5 mA. According to IEC 61800-5-1 a reinforced
Protective Earth connection must be ensured by means of
a min. 10 mm² Cu or an additional PE wire - with the same
cable cross section as the Mains wiring - must be
terminated separately.
Residual Current Device:
This product can cause a DC 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, MN90GXYY.
Protective earthing of the frequency converter and the use
of RCDs must always follow national and local regulations.
Motor thermal protection:
Motor overload protection is possible by setting Parameter
1-90 Motor thermal protection to the value Electronic
Thermal Relay (ETR) trip.
WARNING
Installation at high altitudes
For altitudes above 2 km, please contact Danfoss regarding
PELV.
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.

1.2 Introduction
1.2.1 Available Literature
This quick guide contains the basic information necessary
for installing and running the frequency converter. If more
information is needed, literature can be found on the
enclosed cd or downloaded from:
http://www.danfoss.com/Products/Literature/Technical
+Documentation.htm
1.2.2 Approvals
1.2.3 IT Mains
CAUTION
IT Mains
Installation on isolated mains source, i.e. IT mains.
Max. supply voltage allowed when connected to mains:
440 V (3 x 380-480 V units).
On IP20 200-240 V 0.25-11 kW and 380-480 V IP20 0.37-22
kW, open the RFI switch by removing the screw on the
side of the frequency converter when at IT grid.

On all units, set par. 14-50 RFI filter to OFF when operating
in IT mains.
CAUTION
If reinserted, only use M3 x 12 screw.
1.2.4 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 LCP.
•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.

1.3.5 Connecting to Mains and Motor
The frequency converter is designed to operate all
standard three-phased asynchronous motors. For
maximum cross-section on wires please see section
1.7 General Specifications.
•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
MI02QXYY
•Also see EMC-Correct Installation in the Design
Guide, MG18CXYY.
1. Mount the earth wires to earth terminal.
2. Connect motor to terminals U, V and W.
3. Mount mains supply to terminals L1, L2 and L3
and tighten.

1.3.6 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-circuit 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.
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.
Non UL 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 IEC 61800-5-1:
In case of malfunction, not following the fuse recommen-
dation may result in damage to the frequency converter.

1.3.7 EMC-Correct Electrical Installation
General points to be observed to ensure EMC-correct
electrical installation.
•Use only screened/armoured motor cables and
screened/armoured control cables.
•Connect the screen to earth at both ends.
•Avoid installation with twisted screen ends
(pigtails), since this ruins the screening effect at
high frequencies. Use the cable clamps provide-
dinstead.
•It is important to ensure good electrical contact
from the installation plate through the installation
screws to the metal cabinet of the frequency
converter.
•Use starwashers and galvanically conductive
installation plates.
•Do not use unscreened/unarmoured motor cables
in the installation cabinets.
