1. SAFETY
1.1 Warnings
1 The NX frequency converter is meant for fixed installations only.
2 Do not perform any measurements when the frequency converter is con-
nected to the mains.
3 Do not perform any voltage withstand tests on any part of NX. There is a
certain procedure according to which the tests shall be performed. Ignor-
ing this procedure may result in damaged product.
4 The earth leakage current of NX_ frequency converters exceeds 3.5mA
AC. According to standard EN61800-5-1, a reinforced protective ground
connection must be ensured. See chapter 1.3.
5 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).
6 Only spare parts delivered by Honeywell can be used.
7 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.
8 Prior to measurements on the motor or the motor cable, disconnect the
motor cable from the frequency converter.
9 Do not touch the components on the circuit boards. Static voltage dis-
charge may damage the components.
1.2 Safety instructions
1 The components of the power unit of the frequency converter are live
when 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.
2 The motor terminals U, V, W and the DC-link/brake resistor terminals are
live when NX is connected to mains, even if the motor is not running.
3 After disconnecting the frequency converter from the mains, wait until the
fan stops and the indicators on the keypad go out (if no keypad is at-
tached see the indicators on the cover). Wait 5 more minutes before
doing any work on NX connections. Do not even open the cover before
this time has expired.
4 The control I/O-terminals are isolated from the mains potential. However,
the relay outputs and other I/O-terminals may have a dangerous control
voltage present even when NX is disconnected from mains.
5 Before connecting the frequency converter to mains make sure that the
NX front and cable covers are closed.
ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT

1.3 Earthing and earth fault protection
The NX frequency converter must always be earthed with an earthing conductor connected to the earthing
terminal .
The earth leakage current of NX frequency converters exceeds 3.5mA AC. According to EN61800-5-1, one
or more of the following conditions for the associated protective circuit shall be satisfied:
a. The protective conductor shall have a cross-sectional area of at least 10 mm2Cu or 16 mm2Al, through
its total run.
b. Where the protective conductor has a cross-sectional area of less than 10 mm2Cu or 16 mm2Al, a
second protective conductor of at least the same cross-sectional area shall be provided up to a point
where the protective conductor has a cross-sectional area not less than 10 mm2Cu or 16 mm2Al.
c. Automatic disconnection of the supply in case of loss of continuity of the protective conductor. See chapter 6.
The cross-sectional area of every protective earthing conductor which does not form part of the supply
cable or cable enclosure shall, in any case, be not less than:
a. 2,5mm2 if mechanical protection is provided or
b. 4mm2 if mechanical protection is not provided.
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.
1.4 Running the motor

WARNING

8(110) EU DIRECTIVE
2
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).
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 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 the NX frequency converters with the Direc-
tive 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
cost-efficiency. EMC compliance was a major consideration from the outset of the design.
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 NX frequency converters are designed to fulfil
even the strictest requirements, while as regards the emission level, the customer may want to upgrade
NX's already high ability to filter electro-magnetic disturbances.
2.2.3 Frequency converter EMC classification
NX frequency converters are divided into five classes according to the level of electromagnetic distur-
bances emitted, the requirements of a power system network and the installation environment (see chapter
2.2.3.1). 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 comply with the requirements of category C1 of the product standard
EN 61800-3 (2004). Category C1 ensures the best EMC characteristics and it includes converters the rated
voltage of which is less than 1000V and which are intended for use in the 1st environment. 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 (NX_5, FR4 to FR9 and NX_2, FR4 to FR9):
Frequency converters of this class comply with the requirements of category C2 of the product standard
EN 61800-3 (2004). Category C2 includes converters in fixed installations and the rated voltage of which is
less than 1000V. The class H frequency converters can be used both in the 1st and the 2nd environment.
Class L (Protection classes IP21 and IP54: NX_5 FR10 and greater, NX_6 FR6 and greater):
Frequency converters of this class comply with the requirements of category C3 of the product standard
EN 61800-3 (2004). Category C3 includes converters the rated voltage of which is less than 1000V and
which are intended for use in the second environment only.

EU DIRECTIVE 9(110)
2
Class T:
Frequency converters of this class fulfil the product standard EN 61800-3 (2004) if intended to be used in
IT systems. In IT systems, the networks are isolated from earth, or connected to earth through high imped-
ance to achieve a low leakage current. NOTE: if converters are used with other supplies, no EMC
requirements are complied with.
Class N:
The drives of this class do not provide EMC emission protection. These kinds of drives are mounted in
enclosures. NOTE: An external EMC filter is usually required to fulfil the EMC emission requirements.
All NX frequency converters fulfil all EMC immunity requirements (standard EN 61800-3 (2004).
Note: For changing the EMC protection class of your NX frequency converter from class H or L to class T,
please refer to the instructions given in Chapter 6.1.3.
2.2.3.1 Environment definitions in product standard EN 61800-3 (2004)
First environment: Environment that includes domestic premises. It also includes establishments directly
connected without intermediate transformers to a low-voltage power supply network which supplies
buildings used for domestic purposes.
NOTE: houses, apartments, commercial premises or offices in a residential building are examples of first
environment locations.
Second environment: Environment that includes all establishments other than those directly connected to
a low-voltage power supply network which supplies buildings used for domestic purposes.
NOTE: industrial areas, technical areas of any building fed from a dedicated transformer are examples of
second environment locations.
2.2.4 Manufacturer's declaration of conformity
The following pages present the Manufacturer's Declarations of Conformity assuring the compliance of the
NX frequency converters with the EMC-directives.
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.

3.2 Storage
If the frequency converter is to be kept in store before use make sure that the ambient conditions are
acceptable:
Storing temperature –40…+70°C
Relative humidity <95%, no condensation
If the converter is to be stored during longer periods power should be connected to the converter once a
year and kept on for at least 2 hours. If the storage time exceeds 12 months the electrolytic DC capacitors
need to be charged with caution. Therefore, such a long storage time is not recommended. If longer
storage time is, however, necessary, follow the instructions in chapter 3.3.1 to recharge the capacitors.
3.3 Maintenance
In normal conditions, NX frequency converters are maintenance-free. However, regular maintenance is
recommended to ensure a trouble-free operation and a long lifetime of the drive. We recommend to follow
the table below for maintenance intervals.
Maintenance interval Maintenance action
Whenever necessary •Clean heatsink
Regularly •Check tightening torques of terminals
12 months (if unit stored) •Recharge capacitors (see chapter 3.3.1)
6-24 months
(depending on environment) •Check input and output terminals and control
I/O terminals.
•Clean cooling tunnel.
•Check operation of cooling fan, check for cor-
rosion on terminals, busbars and other surfaces
•Check door filters in case of cabinet installation
5-7 years •Change cooling fans:
-main fan
-internal IP54 fan
-cabinet cooling fan/filter
5-10 years •Change DC bus capacitors
Table 3-1. Maintenance intervals
3.3.1 Capacitor recharge
After a longer storage time the capacitors need to be recharged in order to avoid capacitor damage.
Possible high leakage current through the capacitors must be limited. The best way to achieve this is to
use a DC-power supply with adjustable current limit.
1) Set the current limit to 300…800mA according to the size of the drive.
2) Then connect the DC-power supply to the B+/B- terminals (DC+ to B+, DC- to B-) of the DC-link or
directly to the capacitor terminals. NX converters with no B+/B- terminals (FR8/FR9) can be powered
connecting the DC-supply between two input phases (L1 and L2).
3) In drives FR8 to FR12: To ensure full recharge of capacitors, remove the fuses of the cooling fan. Ask
your distributor for further instructions if necessary.
4) Then set the DC-voltage to the nominal DC-voltage level of the unit (1.35*Un AC) and supply the
converter for at least 1h.
If DC-voltage is not available and the unit has been stored much longer than 12 months deenergized,
consult the factory before connecting power.

4. TECHNICAL DATA
4.1 Introduction
Figure 4-1 presents the block diagram of the NX frequency converter. The frequency converter mechani-
cally consists of two units, the Power Unit and the Control Unit. Pictures of the mechanical assemblage on
pages 54 to 62.
The three-phase AC-choke (1) at the mains end together with the DC-link capacitor (2) form an LC-filter,
which, again, together with the diode bridge produce the DC-voltage supply to the IGBT Inverter Bridge (3)
block. The AC-choke also functions as a filter against High Frequency disturbances from the mains as well
as against those caused by the frequency converter to the mains. It, in addition, enhances the waveform of
the input current to the frequency converter. The entire power drawn by the frequency converter from the
mains is active power.
The IGBT Inverter Bridge 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 con-
trols the motor basing 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 frequency converter. The control keypad is
used for parameter setting, reading status data and giving control commands. It is detachable and can be
operated externally and connected via a cable to the frequency converter. Instead of the control keypad,
also a PC can be used to control the frequency converter if connected through a similar cable.
You can have your frequency converter equipped with a control I/O board which is either isolated (OPT-A8)
or not isolated (OPT-A1) from the ground.
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" Appli-
cation Package. See the "All in One" Application Manual for more information on the different applications.
A brake resistor is available as internal option for frames FR4 to FR6 of voltage classes NX_2 and NX_5.
In all other frames of voltage classes NX_2 and NX_5, as well as in all frames of all other voltage classes,
the brake resistor is available as option and installed externally.
Optional I/O expander boards that increase the number of inputs and outputs to be used are also available.
For closer information, contact the Manufacturer or your local distributor (see back cover).
