This quick guide includes the steps that will enable you to easily install and setup
your Vacon 20 frequency converter.
Before putting your drive into operation, download and read the complete Vacon 20

1. SAFETY
THE ELECTRICAL INSTALLATION MAY ONLY BE CARRIED
OUT BY A COMPETENT ELECTRICIAN!
This quick guide contains clearly marked warnings that are intended for your per-
sonal safety and to prevent any unintentional damage to the product or connected
appliances.
Please read these warnings carefully:
The components of the frequency converter's power unit are
live when Vacon 20 is connected to the 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 optional brake
resistor terminals - / + are live when Vacon 20 is connected to
the 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 even when Vacon 20 is disconnected from
the mains.
The earth leakage current of Vacon 20 frequency converters
exceeds 3.5 mA AC. A reinforced protective ground connection
must be available in accordance with standard EN61800-5-1.
See Chapter 7!
If the frequency converter is used as 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 the mains while the motor is
running, Vacon 20 will remain live if the motor is fed by the
process. In this case, the motor functions as a generator that
feeds 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 switch off. Wait 5 more minutes before
doing any work on Vacon 20 connections.
The motor can start automatically after a fault if the autoreset
function is active.
