Overload protection of the supply cable should be considered (e.g. fuses). The
use of shielded motor cables is recommended; they should be routed as far
away from other cables as possible, and cross other cables at right angles. The
motor cable shield should be grounded at both the NX drive and at the motor.

The installation involves:

mount the controller in position
connect mains cable
connect motor cable
check mains and motor cable insulation
connect control cable
check quality and quantity of cooling air
check inside of drive for condensation
set up links on basic board NX/OPTA1
check all start/stop switches connected to I/O are at stop
switch on power to drive
configure the drive (e.g. using the keypad)
perform run test without motor

Installation on a Trend System

2.2 Sample Applications

2.2.1 NX drive - stand alone

In this application the NX drive is supplied with 3 phase via a fuse and an
isolating contact. An alternative is to use a fused switch (shown dotted). The
start/stop contact connects terminals 6 to 8 to start the drive. The speed is set
by the voltage signal at terminals 2, 3.

The motor local isolator has an early break, late make contact in the circuit
between terminals 6 and 8. If the motor isolator is op erated, the early break
ensures that the drive output is stopped before isolating the motor, and the
motor is connected before the drive output commences.

Installation on a Trend System

2.2.2 NX drive stand alone with start/stop contactor

This application is similar to the previous, but now there is a start/stop
contactor which stops the drive by both isolating the supply to the drive, and
breaking the connection between terminals 6 and 8 (via contacts C1). The
isolating switch will isolate both the drive and the start/stop co ntactor.

NX Variable Speed Drives Installation Manual TG200434 Issue 3/A 04/07/2006 13

Installation on a Trend System

2.2.3 NX drive with Direct On line bypass

In this application the drive can be bypassed.
An Emergency Stop (ES) contact has been added in series with the start/stop

contact which will disconnect the C1 coil, and isolate the drive, and switch it
off via the C1 contacts.

The bypass is operated by a 3 position switch (NX, Off, Bypass).
In the NX position, the time delay contactor, T1, will cause C2 to op erate. C2

is mechanically interlocked to C3 so that as C2 closes C3 cannot close and
stops the motor supply being connected back to the input. Closing C2 also
powers up C1 which puts power on the drive and starts it via terminals 6 and 8.

In the Off position, both drive and bypass are isolated so the motor is off.
In the Bypass position, C3 operates which bypasses the drive via C3 contact

and stops the supply being fed back to the Drive via the open C2 contact.
Another open C2 contact isolates the C1 coil and stops the drive starting. If the
overload contact operates, it opens the bypass, and also de-energises the C3
coil which drops out the C3 bypass contact.

14 NX Variable Speed Drives Installation Manual TG200434 Issue 3/A 04/07/2006

Installation on a Trend System

2.2.4 NX drive with parallel motor operations

In this application, the drive operates 2 motors which are separately isolated by
two local isolators (L1 and L2). Since the NX drive is supplying both motors
in parallel it cannot individually protect them, so each drive has an in-built
thermistor relay which will operate if the motor overheats. TH1 will de­energise C1, and TH2 will de-energise C2. As the start connection between
terminals 6 and 8 consists of C1 and C2 in series, if either motor is isolated or
overheats, both motors will be switched off.

NX Variable Speed Drives Installation Manual TG200434 Issue 3/A 04/07/2006 15

Installation on a Trend System

2.2.5 NX drive with duty/standby motors

This system drives 2 motors in duty/standby e.g. they are both mounted on a
common drive shaft.

The motors are controlled by a three position switch (Motor 1, Off, Motor 2).
If Motor 1 is selected, then closing the start contact will energise the C1 coil

which will connect terminals 6 and 8 together, and connect the output of the
drive to motor 1.

Since the C1 and C2 motor contacts are mechanically interlocked so that
closing one prevents the other from closing; closing C1 will stop C2 closing
and switch off motor 2.

In the Off position neither motor can operate.
Since the circuit is symmetrical, in the Motor 2 position, motor 2 is switched

on and motor 1 is switched off.
The local isolators (L1, L2) will isolate the appropriate motor.

Note that since the C1 and C2 contacts are in parallel across terminals 6 and
8, the motors can operate independently unlike example 1.2.4 above where
they can only operate together.

1.2 Safety instructions

The Vacon NX frequency converter is meant for fixed installations only.

Do not perform any measurements when the frequency converter is
connected to the mains.

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.

The frequency converter has a large capacitive leakage current.

If the frequency converter is used as a part of a machine, the machine
manufacturer is responsible for providing the machine with a main
switch (EN 60204-1).

Only spare parts delivered by Vacon can be used.

The motor starts at power-up if the start command is 'ON'. Furthermore,
the I/O functionalities (including start inputs) may change if parameters,
applications or software are changed. Disconnect, therefore, the motor if
an unexpected start can cause danger.

Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the frequency converter.

Do not touch the components on the circuit boards. Static voltage dis­charge may damage the components.

The components of the power unit of the frequency converter are live

1

when Vacon NX is connected to mains potential. Coming into contact
with this voltage is extremely dangerous and may cause death or se­vere injury. The control unit is isolated from mains potential.

The motor terminals U, V, W and the DC-link/brake resistor terminals

2

are live when Vacon NX is connected to mains, even if the motor is not
running.

After disconnecting the frequency converter from the mains, wait until

3

the fan stops and the indicators on the keypad go out (if no keypad is
attached see the indicators on the cover). Wait 5 more minutes before
doing any work on Vacon NX connections. Do not even open the cover
before this time has expired.

The control I/O-terminals are isolated from the mains potential. How-

4

ever, the relay outputs and other I/O-terminals may have a dangerous
control voltage present even when Vacon NX is disconnected from mains.

Before connecting the frequency converter to mains make sure that the

5

Vacon NX front and cable covers are closed.

1.3 Earthing and earth fault protection

The Vacon NX frequency converter must always be earthed with an earthing conductor connected to the

earthing terminal

The earth fault protection inside the frequency converter protects only the converter itself against earth
faults in the motor or the motor cable. It is not intended for personal safety.

Due to the high capacitive currents present in the frequency converter, fault current protective switches
may not function properly.

EU DIRECTIVE vacon • 9

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).

Vacon NX frequency converters carry the CE label as a proof of compliance with the Low Voltage Directive
(LVD) and the Electro Magnetic Compatibility (EMC). The company SGS FIMKO has acted as the Competent
Body.

2.2 EMC directive

2.2.1 General

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 frequency converters with the EMC directive is verified with Technical Con­struction Files (TCF) checked and approved by SGS FIMKO, which is a Competent Body. The Technical
Construction Files are used to authenticate the comformity of Vacon frequency converters with the Direc­tive because such a large-sized product family is impossible to be tested 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 frequency converters offering the best possible usability and cost­efficiency. EMC compliance was a major consideration from the outset of the design.

Vacon NX frequency converters are marketed throughout the world, a fact which makes the EMC require­ments of customers different. As far as the immunity is concerned, all Vacon NX frequency converters are
designed to fulfil even the strictest requirements, while as regards the emission level, the customer may
want to upgrade Vacon's already high ability to filter electro-magnetic disturbances.

2.2.3 Vacon frequency converter EMC classification

Vacon NX frequency converters are divided into four classes according to the level of electromagnetic
disturbances emitted. The EMC class of each product is defined in the type designation code.

Class C (NX_5, FR4 to FR6, Protection class IP54):
Frequency converters of this class fulfil the requirements of the product standard EN 61800-3+A11 for
the 1st environment (unrestricted distribution) and the 2nd environment.
The emission levels correspond to the requirements of EN 61000-6-3.
Note: If the protection class of the frequency converter is IP21, the requirements of Class C are fulfilled
only as far as the conducted emissions are concerned.

Class H:
Vacon NX_5 frequency converters (FR4 to FR9) and NX_2 frequency converters (FR4 to FR6) have been
designed to fulfil the requirements of the product standard EN 61800-3+A11 for the 1st environment
restricted distribution and the 2nd environment.
The emission levels correspond to the requirements of EN 61000-6-4.

Class L (NX_6 FR6 to FR9 only):
Provides filtering for the 2

nd

environment, restricted distribution according to EN 61800-3+A11.

10 • vacon EU DIRECTIVE

Class T:
The T-class converters have a smaller earth leakage current and are intended to be used with IT supplies
only. If they are used with other supplies no EMC requirements are complied with.

Class N:
The drives of this class do not provide EMC emission protection. This kind of drives are mounted in
enclosures. External EMC filtering is usually required to fulfil the EMC emission requirements.

All Vacon NX frequency converters fulfil all EMC immunity requirements (standards EN 61000-6-1,
EN 61000-6-2 and EN 61800-3+A11).

Warning: This is a product of the restricted sales distribution class according to IEC 61800-3. In a
domestic environment this product may cause radio interference in which case the user may be
required to take adequate measures.

Note: For changing the EMC protection class of your Vacon NX frequency converter from class H or L to
class T, please refer to the instructions given in Chapter 6.1.3.
