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 otherlocations 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

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 manufacturer can be used.
1.2 Safety instructions
1
The VACON®NX inverter is meant for fixed installations only.
2
Do notperform 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 notperform 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 Grounding and earth fault protection
The VACON®NX inverter must always be earthed with an grounding conductor connected to the
grounding 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 carries the CE label as a proof of compliance with the Low Voltage Directive (LVD), Electro
Magnetic Compatibility (EMC) Directive and RoHS Directive.
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
otherdisturbances 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 Notified Body. The
Technical Construction Files are used to authenticate the conformity of VACON®NX 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 (standard 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.
