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 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 per­formed. 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 dis­charge may damage the components.

7

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 capacitive 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 cost­efficiency. EMC compliance was a major consideration from the outset of the design.

Vacon NX inverters are marketed throughout the world, a fact which makes the EMC requirements
of customers different. As far as immunity is concerned, all Vacon NX inverters are designed to fulfil
even the strictest requirements.

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. If they
are used with other supplies, no EMC requirements are complied with.

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.

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. To protect the DC-link capacitors,
the Power Unit also contains a charging circuit for controlled DC-link charge. Use the B+ and DC­terminals in order to bypass the charging circuit.

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).

5. INSTALLATION

5.1 Mounting

The inverter can be mounted in either a vertical or horizontal position on a wall or on the back plane
of a cubicle. Enough space must be reserved around the inverter to ensure sufficient cooling, see
Figure 5-6. You must follow the minimum dimensions for installation, see Table 5-6 and Table 5-7.
Also make sure that the mounting plane is relatively even.

The inverter is fixed with four screws (or bolts, depending on the unit size). The dimensions for
installation are presented in Figure 5-6 and Table 5-6.

Lift units bigger than FR7 out of the package using a jib crane. Ask the factory or your local
distributor for information on how to lift the unit safely.

The following pages show the dimensions for Vacon NX with a default enclosure in Figure 5-1, and
with flange mounting in Figures 5-2 and Figure 5-4. Dimensions for the opening needed in flange
mounting are given in Table 5-3 and Table 5-5.
