This quick guide includes the essential steps for easy
installation and setup of your Vacon 20 frequency converter.
Before commissioning your drive, download and read the complete
Vacon 20 User Manual available at:
http://drives.danfoss.com/knowledge-center/technical-documentation/
1. SAFETY
ONLY A COMPETENT ELECTRICIAN IS ALLOWED TO
CARRY OUT THE ELECTRICAL INSTALLATION!
This quick guide contains clearly marked warnings which are intended for your per-
sonal safety and to avoid any unintentional damage to the product or connected ap-
pliances.
Please read these warnings carefully:
The components of the power unit of the frequency converter
are live when Vacon 20 is connected to mains. Coming into
contact with this voltage is extremely dangerous and may
cause death or severe injury.
The motor terminals U, V, W (T1, T2, T3) and the possible brake
resistor terminals - / + are live when Vacon 20 is connected to
mains, even if the motor is not running.
The control I / O-terminals are isolated from the mains poten-
tial. However, the relay output terminals may have a danger-
ous control voltage present even when Vacon 20 is
disconnected from mains.
The earth leakage current of Vacon 20 frequency converters
exceeds 3.5 mA AC. According to standard EN61800-5-1, a
reinforced protective ground connection must be ensured.
See Chapter 7!
If the frequency converter is used as a part of a machine, the
machine manufacturer is responsible for providing the
machine with a main switch (EN 60204-1).
If Vacon 20 is disconnected from mains while running the
motor, it remains live if the motor is energized by the process.
In this case the motor functions as a generator feeding energy
to the frequency converter.
After disconnecting the frequency converter from the mains,
wait until the fan stops and the display segments or status
leds on the front panel go out. Wait 5 more minutes before
doing any work on Vacon 20 connections.
The motor can start automatically after a fault situation, if the
autoreset function has been activated.

2. INSTALLATION
2.1 Mechanical installation
There are two possible ways to mount Vacon 20 in the wall. For MI1 - MI3, either
screw or DIN-rail mounting; For MI4 - MI5, screw or flange mounting.

Note! See the mounting dimensions on the back of the drive.
Leave free space for cooling above (100 mm), below (50 mm), and on the sides
(20 mm) of Vacon 20! (For MI1 - MI3, side-to-side installation allowed only if the am-
bient temperature is below 40 °C; For MI4 - MI5, side-to-side installation is not al-
lowed.

4.2 Commissioning and startup wizard
4.2.1 Commissioning steps:
4.2.2 Startup wizard
Vacon 20 runs the startup wizard in first power-up. The wizard can be run by setting
SYS Par.4.2 =1. The following figures show the procedure.
NOTE! Running the startup wizard will always return all parameter
settings to their factory defaults!
NOTE! StartUp-Wizard can be skipped after pressing STOP button
continuously for 30 seconds
1. Read safety instructions on page 1
7. Perform test run without motor, see the
User Manual at http://drives.danfoss.com/
knowledge-center/technical-documentation/
2. Secure the grounding and check that cables
comply with requirements
8. Run no-load tests without motor being con-
nected to the process
3. Check quality and quantity of cooling air 9. Perform an identification run (Par. ID631)
4. Check that all start / stop switches are in
STOP position
10. Connect the motor to the process and per-
form test run once again
5. Connect the drive to mains 11. Vacon 20 is now ready for use
6. Run the Startup wizard and set all necessary
parameters
