ABOUT THE VACON NXI USER'S MANUAL
AND THE ”All in One” APPLICATION MANUAL
Congratulations for choosing Vacon NX Inverters!
The User's Manual will provide you with the necessary information about the installation,
commissioning and operation of Vacon NX Inverters. We recommend that you carefully study these
instructions before powering up the inverter for the first time.
In the All in One Application Manual you will find information about the different applications
included in the All in One Application Package. Should these applications not meet the requirements
of your process, please contact the manufacturer for information on special applications.
This manual is available in both paper and electronic editions. We recommend you to use the
electronic version if possible. If you have the electronic version at your disposal, you will be able to
benefit from the following features:
The manual contains several links and cross-references to other locations in the manual, which
makes it easier to move around in the manual. The reader can thus easily find and check things.
The manual also contains hyperlinks to web pages. To visit these web pages through the links, you
must have an internet browser installed on your computer.

1. SAFETY
1.1 Warnings
1
The components of the power unit of the inverter are
live
when the Vacon
NX is connected to DC supply.
Coming into contact with this voltage is
extremely dangerous and may cause death or severe injury.
The
control unit is isolated from mains potential.
2
The DC supply and motor terminals are
live
when the Vacon NX is
connected to DC supply,
even if the motor is not running
.
3
The control I/O-terminals are isolated from the mains potential.
However, the relay outputs and other I/O-terminals may have dangerous
control voltage present even when the Vacon NX is disconnected from the
DC supply.
4
The inverter has a large capacitive leakage current.
5
If the inverter is used as a part of a machine, the machine manufacturer
is responsible for providing the machine with a main switch (EN 60204-1).
6
Only spare parts delivered by Vacon can be used.
1.2 Safety instructions
1
The Vacon NX inverter is meant for fixed installations only.
2
Do not perform any measurements when the inverter is connected to the
DC supply.
3
After having disconnected the inverter from the DC supply, wait until the
fan stops and the indicators on the keypad go out (if no keypad is
attached see the indicator through the keypad base). Wait 5 more
minutes before doing any work on Vacon NX connections. Do not even
open the cover before this time has expired.
4
Do not perform any voltage withstand tests on any part of Vacon NX.
There is a certain procedure according to which the tests shall be per-
formed. Ignoring this procedure may result in damaged product.
5
Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the inverter.
6
Do not touch the components on the circuit boards. Static voltage dis-
charge may damage the components.
7
Before connecting the inverter to DC supply, make sure that the Vacon
NX front and cable covers are closed.
ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT
THE ELECTRICAL INSTALLATION

1.3 Earthing and earth fault protection
The Vacon NX inverter must always be earthed with an earthing conductor connected to the earthing
terminal.
The earth fault protection inside the inverter only protects the inverter against earth faults in the
motor or the motor cable.
Due to the high capacity currents present in the inverter, fault current protective switches may not
function properly. If fault current protective switches are used, they need to be tested with earth
fault currents present during possible fault situations.
1.4 Running the motor
Warning symbols
For your own safety, please pay special attention to the instructions marked with the following
symbols:
=
Dangerous voltage
WARNING
=
General warning
HOT SURFACE
=
Hot surface – Risk of burn
MOTOR RUN CHECK LIST
1
Before starting the motor, check that the motor is mounted properly and
ensure that the machine connected to the motor allows the motor to be
started.
2
Set the maximum motor speed (frequency) according to the motor and
the machine connected to it.
3
Before reversing the motor, make sure that this can be done safely.
4
Make sure that no power correction capacitors are connected to the
motor cable.
5
Make sure that the motor terminals are not connected to mains
potential.

2. EU DIRECTIVE
2.1 CE marking
The CE marking on the product guarantees the free movement of the product within the EEA
(European Economic Area). It also guarantees that the product complies with applicable directives
(for example, the EMC directive and other possible so-called new method directives).
Vacon NX inverters carry the CE label as a proof of compliance with the Low Voltage Directive (LVD)
and the Electro Magnetic Compatibility (EMC) directive. SGS FIMKO has acted as the Competent
Body.
2.2 EMC directive
2.2.1 Introduction
The EMC Directive provides that the electrical apparatus must not excessively disturb the
environment it is used in, and, on the other hand, it shall have an adequate level of immunity toward
other disturbances from the same environment.
The compliance of Vacon NX inverters with the EMC directive is verified with Technical Construction
Files (TCF) and checked and approved by SGS FIMKO, which is a Competent Body. The Technical
Construction Files are used to authenticate the conformity of Vacon inverters with the Directive
because it is impossible to test such a large product family in a laboratory environment and because
the combinations of installation vary greatly.
2.2.2 Technical criteria
Our basic idea was to develop a range of inverters offering the best possible usability and cost-
efficiency. EMC compliance was a major consideration from the outset of the design.
2.2.3 Vacon inverter EMC classification
Factory delivered Vacon NX inverters are Class T equipment, which fulfil all EMC immunity
requirements (standards EN 50082-1, 50082-2 and EN 61800-3).
Class T:
Class T equipment have a small earth leakage current and can be used with floating DC input.
2.2.4 Manufacturer's declaration of conformity
The following page presents the photocopy of the Manufacturer's Declaration of Conformity assuring
the compliance of Vacon Inverters with the EMC-directives
Warning:
This product is of the restricted sales distribution class according to IEC 61800-3. In
residential areas, this product may cause radio interference in which case the user may be required
to take adequate measures.
