SAFETY
ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT
THE ELECTRICAL INSTALLATION
1.1 Danger
2
3
5
6
1
4
The components of the power unit of the frequency converter are live 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 motor terminals U, V, W and the DC-link/brake resistor terminals 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 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.
Always ensure absence of voltage before starting any electrical work!
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 Vacon NX_ is disconnected from mains.
Before connecting the frequency converter to mains make sure that the
Vacon NX_ front and cable covers are closed.
If Vacon NX_ is disconnected from mains while running the motor, it remains live if the motor is energized by the process. In this case the motor functions as a generator feeding energy to the frequency converter.

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.
The earth leakage current of Vacon NX_ frequency converters exceeds 3.5 mA AC. According to standard EN61800-5-1, a reinforced protective ground
connection must be ensured. See Chapter 1.4.
If the frequency converter is used as a part of a machine, the machine manufacturer is responsible for providing the machine with a disconnecting device (EN 60204-1).
Only spare parts delivered by Vacon can be used.
After the power-up, power brake or fault reset the motor will start immediately if the start signal is active, unless the pulse control for
Start/Stop logic has been selected. Futhermore, the I/O functionalities
(including start inputs) may change if parameters, applications or software are changed. Disconnect, therefore, the motor if and unexpected start can cause danger.
Prior to measurements on the motor or the motor cable, disconnect the motor cable from the frequency converter.

1 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.
Do not touch the components on the circuit boards. Static voltage discharge may damage the components.
If a fault protection relay is used, it must be of at least type B, preferably B+
(according to EN 50178) , with a trip level of 300 mA. This is for fire protection, not for touch protection in grounded systems.
1.4 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 leakage current of Vacon NX_ exceeds 3.5 mA AC. According to EN61800-5-1, one or more of the following measures shall be applied, unless the touch current can be shown to be less than 3.5 mA AC or
10 mA DC:
A fixed connection and a. The protective earthing conductor shall have a cross-sectional area of at least 10 mm mm 2 Al,
2 Cu or 16 or b. An automatic disconnection of the supply in case of loss of continuity of the protective earthing conductor.
or c. Provision of an additional terminal for a second protective earthing conductor of the same crosssectional area as the original protective earthing conductor,

The values above are valid only if the protective earthing conductor is made of the same metal as the phase conductors. If this is not so, the cross-sectional area of the protective earthing conductor shall be determined in a manner which produces a conductance equivalent to that which results from the application of this table.
Table 1. Protective earthing conductor cross-section
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:
-
2,5 mm
-
4 mm 2
2 if mechanical protection is provided or
if mechanical protection is not provided. For cord-connected equipment, provisions shall be made so that the protective earthing conductor in the cord shall, in the case of failure of the strain-relief mechanism, be the last conductor to be interrupted.

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 conformity 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 five classes according to the level of electromagnetic disturbances 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.
Vacon EMC class C1 (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 C1 are fulfilled only as far as the conducted emissions are concerned.
Vacon EMC class C2 (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 C2 frequency converters can be used both in the 1st and the 2nd environment.
Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: [email protected]
Vacon EMC 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 1000 V and which are intended for use in the second environment only.
Vacon EMC 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 impedance to achieve a low leakage current. NOTE! If converters are used with other supplies, no EMC requirements are complied with.
Vacon EMC 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 Vacon NX_ frequency converters fulfil all EMC immunity requirements (standard EN 61800-3
(2004).
Warning: 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.
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.

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
3.3 Maintenance
In normal conditions, Vacon 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
Whenever necessary
Regularly
12 months (if unit stored)
6-24 months
(depending on environment)
5-7 years
Maintenance action
• Clean heatsink
• Check tightening torques of terminals
• Recharge capacitors (see chapter 3.3.1)
• Check input and output terminals and control
I/O terminals.
• Clean cooling tunnel.
• Check operation of cooling fan, check for corrosion on terminals, busbars and other surfaces
• Check door filters in case of cabinet installation
• Change cooling fans:
main fan
internal IP54 fan
cabinet cooling fan/filter
• Change DC bus capacitors 5-10 years
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 factory 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 re-energised, consult the factory before connecting power.

TECHNICAL DATA
4.1 Introduction
Figure 4-1 presents the block diagram of the Vacon NX_ frequency converter. The frequency converter
mechanically consists of two units, the Power Unit and the Control Unit. Pictures of the mechanical
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 controls 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 brake resistor can be installed internally in sizes FR4 to FR6 (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.
Brake chopper belongs to the standard equipment in sizes FR4 to FR6, while in greater sizes
(FR7 to FR9) it is optional.

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 (OPTA8) or not isolated (OPTA1) 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+"
Application 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).

INSTALLATION
5.1 Mounting
The frequency converter can be mounted in either vertical or horizontal position on the wall or on the back plane of a cubicle. However, if the drive is mounted in a horizontal position, it is not protected against vertically falling drops of water.
Enough space shall be reserved around the frequency converter in order to ensure a sufficient cooling, see
Figure 5-10, Table 5-10 and Table 5-11. Also see to that the mounting plane is relatively even.
The frequency converter shall be fixed with four screws (or bolts, depending on the unit size). The
dimensions of installation are presented in Figure 5-10 and Table 5-10.
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.
Below you will find the dimensions of both wall-mounted as well as flange-mounted Vacon NX_ frequency
The sizes FR10 to FR12 are floorstanding units. The enclosures are equipped with fixing holes. For dimensions see below.

5.2 Cooling
Enough free space shall be left around the frequency converter to ensure sufficient air circulation, cooling as well as maintenance. You will find the required dimensions for free space in the tables below.
If several units are mounted above each other the required free space equals C + D (see figure below).
Moreover, the outlet air used for cooling by the lower unit must be directed away from the air intake of the upper unit.
The amount of cooling air required is indicated below. Also make sure that the temperature of the cooling air does not exceed the maximum ambient temperature of the converter.

5.3 Power losses
5.3.1
Power losses as function of switching frequency
If the operator wants to raise the switching frequency of the drive for some reason (typically e.g. in order to reduce the motor noise), this inevitably affects the power losses and cooling requirements according to the graphs below.

CABLING AND CONNECTIONS

6.1.1
Power connections
6.1.1.1
Mains and motor cables
The mains cables are connected to terminals L1, L2 and L3 and the motor cables to terminals marked with
U, V and W. A cable entry gland should be used when installing the motor cable at both ends in order to
reach the EMC levels. See Table 6-1 for the cable recommendations for different EMC levels.
Use cables with heat resistance of at least +70
°
C. The cables and the fuses must be dimensioned according to the frequency converter nominal OUTPUT current which you can find on the rating plate. Dimensioning according to the output current is recommended because the frequency converter input current never significantly exceeds
Recommended fuse types: gG/gL, see Table 6-2 and Table 6-3;
If the motor temperature protection of the drive (see Vacon All in One Application Manual) is used as an overload protection, the cable shall be chosen accordingly. If three or more cables are used in parallel for bigger units each cable requires a separate overload protection.
These instructions apply only to cases with one motor and one cable connection from the frequency converter to the motor. In any other case, ask the factory for more information.

6.1.1.2
DC supply and brake resistor cables
Vacon frequency converters are equipped with terminals for the DC supply and an optional external brake resistor. These terminals are marked with B–, B+/R+ and R–. The DC bus connection is made to terminals
B– and B+ and the brake resistor connection to R+ and R–. Note that the DC connection is optional for drives greater than FR8.

Installation instructions
Before starting the installation, check that none of the components of the frequency converter is live.
Place the motor cables sufficiently far from other cables:
Avoid placing the motor cables in long parallel lines with other cables
If the motor cables runs in parallel with other cables, note the minimum distances between the motor cables and other cables given in table below.
The given distances also apply between the motor cables and signal cables of other systems.

The total maximum length of motor cables incl. shielded cables should not exceed
300 m (units with power greater than 1.5 kW) and 100 m (units with power from 0.75
to 1.5 kW). If used motor cables exceed these limits contact factory for more information.
NOTE! Each parallel cable adds to the total length.
NOTE! If you use long motor cables (max. 100m) together with small drives (≤1.5 kW) the motor current measured by the drive can be much higher than the actual motor current due to capacitive currents in the motor cable. Consider this when setting up the motor stall protection functions
.
The motor cables should cross other cables at an angle of 90 degrees.
If cable insulation checks are needed, see Chapter 6.1.7.
Connect the cables:
Strip the motor and mains cables as advised in Table 6-6 and Figure 6-7.
Remove the screws of the cable protection plate. Do not open the cover of the power unit!
Make holes into and pass the cables through the rubber grommets on the bottom of
the power unit (see Chapter 6.1.4). Note: Use a cable gland instead of the grommet in
types where this is required.
Connect the mains, motor and control cables into their respective terminals (see
For information on the installation of greater units, please contact the factory or your local distributor.
For Information on cable installation according to UL regulations see Chapter
Make sure that the control cable wires do not come in contact with the electronic components of the unit.
If an external brake resistor (option) is used, connect its cable to the appropriate terminal.
Check the connection of the earth cable to the motor and the frequency converter terminals marked with .
Connect the separate shield of the power cable to the earth terminals of the frequency converter, motor and the supply centre.
Attach the cable protection plate with the screws.
Ensure that the control cables or the cables of the unit are not trapped between the frame and the protection plate.

Cable selection and unit installation in accordance with the UL standards
To meet the UL (Underwriters Laboratories) regulations, use a UL-approved copper cable with a minimum heat-resistance of +60/75
°
C. However, for sizes NX_0170 2 and NX_0168 5 always use cables with heat resistance of at least +90 °C to meet the requirements.
Use Class 1 wire only.
The units are suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes, 600 V maximum, when protected by T and J Class fuses.
Integral solid state short circuit protection does not provide branch circuit protection. Branch circuit protection must be provided in accordance with the National Electric Code and any additional local codes.
Branch circuit protection provided by fuses only.
The tightening torques of the terminals are given in Table 6-7.

6.1.7
Cable and motor insulation checks
1. Motor cable insulation checks
Disconnect the motor cable from terminals U, V and W of the frequency converter and from the motor.
Measure the insulation resistance of the motor cable between each phase conductor as well as between each phase conductor and the protective ground conductor. The insulation resistance must be
>1MΩ.
2. Mains cable insulation checks
Disconnect the mains cable from terminals L1, L2 and L3 of the frequency converter and from the mains. Measure the insulation resistance of the mains cable between each phase conductor as well as between each phase conductor and the protective ground conductor. The insulation resistance must be
>1MΩ.
3. Motor insulation checks
Disconnect the motor cable from the motor and open the bridging connections in the motor connection box. Measure the insulation resistance of each motor winding. The measurement voltage must equal at least the motor nominal voltage but not exceed 1000 V. The insulation resistance must be >1MΩ.

6.2 Control unit
The control unit of the frequency converter consists roughly of the control board and additional boards (see
Figure 6-24 and Figure 6-25) connected to the five
slot connectors
(A to E) of the control board. The control board is connected to the power unit through a D-connector (1) or fibre optic cables (FR9).
Figure 6-24. NX control board Figure 6-25. Basic and option board connections on the control board
Usually, when the frequency converter is delivered from the factory, the control unit includes at least the standard compilation of two basic boards (I/O board and relay board) which are normally installed in slots
at the factory are indicated in the type code. For more information on the option boards, see Vacon NX option board manual (ud741).
The control board can be powered externally (+24 V, ±10%) by connecting the external power source to
and for keeping the fieldbus active. Note however that the analogue inputs and outputs as well as the measurements of the main circuit (e.g. DC-link voltage, unit temperature) are not available when the mains is not connected (with the exception of frame size FR9 and bigger).
NOTE! If the 24 V inputs of several frequency converters are parallelly connected we recommend to use a diode in terminal #6 (or #12) in order to avoid the current to flow in opposite direction. This might damage the control board. See picture below.

Jumper selections on the OPTA1 basic board
The user is able to customise the functions of the frequency converter to better suit his needs by selecting certain positions for the jumpers on the OPTA1 board. The positions of the jumpers determine the signal type of analogue and digital inputs.
On the A1 basic board, there are four jumper blocks X1, X2, X3 and X6 each containing eight pins and two
jumpers. The selectable positions of the jumpers are shown in Figure 6-32.

CONTROL KEYPAD
The control keypad is the link between the Vacon frequency converter and the user. The Vacon NX control keypad features an alphanumeric display with seven indicators for the Run status (RUN, , READY,
STOP, ALARM, FAULT) and three indicators for the control place (I/O term/ Keypad/BusComm). There are
also three Status Indicator LEDs (green - green - red), see Status LEDs (green – green – red) below.
The control information, i.e. the number of menu, description of menu or the displayed value and the numeric information are presented on three text lines.
The frequency converter is operable through the nine push-buttons of the control keypad. Furthermore, the buttons serve the purposes of parameter setting and value monitoring.
The keypad is detachable and isolated from the input line potential.

Table 7-3. Fault types
Meaning
This type of fault is a sign of an unusual operating condition. It does not cause the drive to stop, nor does it require any special actions. The 'A fault' remains in the display for about 30 seconds.
An 'F fault' is a kind of fault that makes the drive stop.
Actions need to be taken in order to restart the drive.
If an 'AR fault' occurs the drive will also stop immediately. The fault is reset automatically and the drive tries to restart the motor. Finally, if the restart is not successful, a fault trip (FT, see below) occurs.
If the drive is unable to restart the motor after an AR fault an FT fault occurs. The effect of the 'FT fault' is basically the same as that of the F fault: the drive is stopped.

Copy parameters
The parameter copy function is used when the operator wants to copy one or all parameter groups from one drive to another or to store parameter sets in the internal memory of the converter. All the parameter groups are first
uploaded
parameter groups are to the keypad, then the keypad is connected to another drive and then the
downloaded
to it (or possibly back to the same drive).
Before any parameters can successfully be copied from one drive to another the drive has to be stopped when the parameters are downloaded to it:
The parameter copy menu (S6.3) embodies four functions:

When the Parameter backup function is activated Vacon NX control keypad makes a copy of the parameters of the presently used application. Every time a parameter is changed the keypad backup is automatically updated.
When applications are changed, you will be asked if you wish the parameters of the new application to be
uploaded to the keypad. For this to happen, push the
Enter button
. If you wish to keep the copy of the
parameters of the previously used application saved in the keypad push any other button. Now you will be
able to download these parameters to the drive following the instructions given in Chapter 7.3.6.3.
If you want the parameters of the new application to be automatically uploaded to the keypad you have to do this for the parameters of the new application once on Page 6.3.2 as instructed. Otherwise the panel will always ask for the permission to upload the parameters.
NOTE! Parameters saved in the parameter settings on page S6.3.1 will be deleted when applications are changed. If you want to transfer the parameters from one application to another you have to upload them first to the keypad.

Fan control (P6.7.2)
This function allows you to control the frequency converter’s cooling fan. You have four alternatives to choose between for the function of the fan:
1.
2.
Continuous (default setting);
Temperature;
The fan runs continuously when the power is switched on.
The fan is switched on automatically when the heatsink temperature reaches 60 °C or the converter is in RUN state. The fan receives a stop command when the heatsink temperature falls to 55 °C and the converter is in STOP state. However, the fan runs for about a minute after receiving the stop command or switching on the power, as well as after changing the value from
3.
4.
Continuous
to
Temperature.
First start;
When power is switched on the fan is in stop state. Once the first start command for the drive is given the fan runs continuously.
Calc temp;
Fan function depends on the calculated IGBT temperature:
If IGBT temp > 40 °C the fan starts running.
If IGBT temp < 30 °C the fan stops.
NOTE: As the presumed temperature at power-up is 25 °C the fan will not immediately start operating.
NOTE! The fan runs always when the drive is in RUN state.

HMI acknowledge timeout (P6.7.3)
This function allows the user to change the timeout of the HMI acknowledgement time in cases where there is an additional delay in the RS-232 transmission due to use of modems for communication over longer distances, for example.
Note! If the frequency converter has been connected to the PC with a normal cable, the default values of parametres 6.7.3 and 6.7.4 (200 and 5) must not be changed.
If the frequency converter has been connected to the PC via a modem and there is delay in transferring messages, the value of par. 6.7.3 must be set according to the delay as follows:
Example:
• Transfer delay between the frequency converter and the PC = 600 ms
• The value of par. 6.7.3 is set to 1200 ms (2 x 600, sending delay + receiving delay)
• The corresponding setting shall be entered in the [Misc]-part of the file NCDrive.ini:
Retries = 5
AckTimeOut = 1200
TimeOut = 6000
It must also be considered that intervals shorter than the AckTimeOut-time cannot be used in NC-Drive monitoring.

7
8
1
2
3
Internal components and circuit boards of the frequency converter (except for the galvanically isolated I/O terminals) are live 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 motor terminals U, V, W and the DC-link/brake resistor terminals –/+ are live when Vacon NX_ is connected to mains, even if the motor is not running.
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 Vacon NX_ is disconnected from mains.
Do not make any connections with the frequency converter connected to the mains.
After having disconnected the frequency converter from the mains, 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.
Before connecting the frequency converter to mains make sure that the
Vacon NX_ front cover is closed.
When running, the side of converter FR8 is burning hot. Do not touch with hands!
When running, the back of frequency converter FR6 is burning hot.
Therefore it MUST NOT be mounted onto a surface which is not fireproof.
8.2 Commissioning of the frequency converter
1 Read carefully the safety instructions in Chapter 1 and above and follow them.
2
After the installation, pay attention to:
- that both the frequency converter and the motor are grounded.
- that the mains and motor cables comply with the requirements given in Chapter 6.1.1.
- that the control cables are located as far as possible from the power cables (see Chapter
6.1.5, step 3) , the shields of the shielded cables are connected to protective earth
. The wires may not touch the electrical components of the frequency converter.
- that the common inputs of digital input groups are connected to +24 V or ground of the I/O terminal or the external supply.
3 Check the quality and quantity of cooling air (Chapter 5.2 and Table 5-11).
4 Check the inside of the frequency converter for condensation.
5 Check that all Start/Stop switches connected to the I/O terminals are in Stop-position.
6 Connect the frequency converter to mains.
