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.

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.

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).

3.2 Storage
If the inverter is to be stored before use, make sure that the ambient conditions are acceptable:
Storage temperature –40…+70°C
Relative humidity <95%, no condensation
When inverter units are stored without voltage being applied, the recharging of the capacitors
should be done at least once a year by connecting voltage into the unit and keeping it powered at
least for 1 hour.
If the storing time is much longer than one year, the recharging of the capacitors has to be carried
out so that the possible high leakage current through the capacitors is limited. The best alternative
is to use DC-power supply with adjustable current limit. Current limit has to be set for example to
300…500mA and DC-power supply has to be connected to the B+/B- terminals (DC supply terminals).
DC-voltage must be adjusted up to nominal DC-voltage level of the unit (1.35*Un ac) and shall be
supplied at least for 1 hour.
If DC-voltage is not available and unit has been stored much longer than 1 year de-energized,
consult factory before connecting the power.
3.3 Maintenance
All technical devices, drives as well, need a certain amount of care-taking and failure preventive
maintenance. To maintain trouble-free operation of the drive, environmental conditions, as well as
load, line power, process control, etc. have to be within specifications, determined by manufacturer.
If all conditions are in accordance with the manufacturer's specifications, there are no other
concerns, but to provide a cooling capacity high enough for the power- and control circuits. This
requirement can be met by making sure, that the cooling system works properly. Operation of
cooling fans and cleanness of the heat sink should be verified regularly.
Regular maintenance is recommended to ensure trouble free operation and long lifetime of the
drive. At least the following things should be included in the regular maintenance.

4. TECHNICAL DATA
4.1 Introduction
The figure below presents the block diagram of the Vacon NX inverter. The inverter mechanically
consists of two units, the Power Unit and the Control Unit.
The Power Unit contains an inverter bridge which consists of IGBT switches and produces a
symmetrical, 3-phase PWM-modulated AC voltage to the motor.
The Motor and Application Control Block is based on microprocessor software. The microprocessor
controls the motor based on the information it receives through measurements, parameter settings,
control I/O and control keypad. The motor and application control block controls the motor control
ASIC which, in turn, calculates the IGBT positions. Gate drivers amplify these signals for driving the
IGBT inverter bridge.

The control keypad constitutes a link between the user and the inverter. The control keypad is used
for parameter setting, reading status data and giving control commands. It is detachable and can be
operated externally and is connected via a cable to the inverter. Instead of the control keypad, a PC
can be used to control the inverter if connected through a similar cable (VACON RS232PC –1.5M).
The basic control interface and the parameters (the Basic Application) are easy to use. If a more
versatile interface or parameters are required, a more suitable application can be chosen from the
"All in One+" Application Package. See the "All in One+" Application Manual for more information on
the different applications.
Optional I/O expander boards that increase the number of inputs and outputs to be used are also
available. For more information, contact the Manufacturer or your local distributor (see back cover).
