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.
The DC supply and motor terminals are live when the Vacon NX is connected to DC supply, 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 dangerous control voltage present even when the Vacon NX is disconnected from the
DC supply.
The inverter has a large capacitive leakage current.
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).
Only spare parts delivered by Vacon can be used.

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.

eu directive vacon • 9
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.
2.2.1 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.
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.
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.
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.

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).

5. INSTALLATION
5.1 Mounting
The inverter can be mounted in a vertical position on the back plane of a cubicle. Enough space must be reserved around the inverter to ensure sufficient cooling, see Figure 5-7. Follow the minimum
dimensions for installation, see Table 5-1 and Table 5-2. 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 5-7
and Table 5-1.The following pages show the
dimensions for IP00 power module.

5.2.1 Frames FI9 to FI14
Enough free space must be left around the inverter to ensure sufficient air circulation and cooling.
You will find the required dimensions for free space in the table below.
If several units are mounted on top of each other, the required free space equals 2 * C (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. When planning the cooling for the space, take into consideration that the inverter’s heat loss is approx. 2.5% of the nominal capacity.

Table 5-2. Required cooling air
5.2.2 Arranging ventilation of the enclosure
The enclosure door must be provided with air gaps for air intake. To achieve sufficient cooling inside the cabinet, the dimensions for the total area of free openings for incoming air given in Table 5-2 must be followed. For instance, there could be two screened gaps as presented in Figure 5-7
(Vacon's recommendation). This layout ensures a sufficient air flow to the module fans as well as cooling of the additional components.
Air outlet gaps must be situated on top of the cabinet. The minimum effective air outlet area per converter frame is given in Table 5-2. The cooling arrangements inside the cabinet must be such that they prevent hot output air from mixing with the incoming fresh air (see page 32).
The ventilation gaps must fulfil the requirements set by the selected IP class. The examples in this manual apply to protection class IP21.
During operation, air is sucked in and circulated by a fan blower at the bottom of the power unit. If the power unit is placed in the upper part of the cabinet, the fan blower will be in the mid of the cabinet, at the height of the upper ventilation grid.

STEERING AIR FLOW
Cooling air must be taken in through the ventilation gaps on the door and blown out at the top of the enclosure. To steer the hot air from the power unit to the outlet at the top of the enclosure and prevent it from circulating back to the fan blower, use either of the following arrangements:
A. Install a closed air duct from the power unit to the outlet on top of the enclosure (A in figures below).
B. Install shields in the gaps between the power unit and the cabinet walls (B in figures below). Place the shields above the air outlet gaps at the sides of the module.

6.1.1.1 DC supply and motor cables
The power supply is connected to terminals B+ and B- and the motor cables to terminals U/T1, V/T2 and W/T3. A cable entry gland should be used at the motor cable end to reach the EMC levels, see
Use cables with a heat resistance of at least +70°C. The cables and the fuses must be sized according to the inverter nominal output current which can be found on the rating plate. Installation
of cables according to UL regulations is presented in Chapter 6.1.3 and aR fuse sizes in Tables 6-2
and 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.
These instructions apply only to installations with one motor and one cable connection from the inverter to the motor. In any other case, ask the factory for more information.
Cable type EMC Level T
Power supply
Motor cable
Control cable
Flexible conductor. Min. temperature endurance for isolation 70°C

Before starting the installation, check that none of the components of the inverter are live.
In accordance with protection class IP00 requirements. There is no need to install the inverter cover if the inverter is installed in a cubicle, separate cabinet or device space.
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 the table below.
The given distances also apply between the motor cables and signal cables of other systems.
The maximum length of the motor cables is 300 m.
If output du/dt filters (+DUT option) are used the cable length is limited according to the table below:

5 Connect the cables:
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. The rubber grommets are delivered in a separate bag.
Connect the DC supply, motor and control cables into their respective terminals.
For Information on cable installation according to UL
regulations, see Chapter 6.1.3.
Cable installation according to EMC regulations:
The output cables to the motor must be 360 o
EMC earthed. The
EMC grounding clamps can, for instance, be installed on the mounting plate. The EMC grounding clamps must be suited to the output cable diameter to give a 360 o contact with the cables.
Make sure that the control cable wires do not come in contact with the electronic components of the unit.
Check the connection of the earth cable to the motor and the inverter terminals marked with .
Connect the separate shield of the power cable to the earth terminals of the inverter, 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.

6.1.4 Cable and motor insulation checks
1. Motor cable insulation checks
Disconnect the motor cable from terminals U, V, and W of the inverter 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. DC supply cable insulation checks
Disconnect the DC supply cable from terminals DC- and DC+ of the inverter and from DC supply.
Measure the insulation resistance between each conductor and ground.
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 1,000 V.
The insulation resistance must be >1MΩ.

control signal descriptions. The I/O boards mounted 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 (+24V) by connecting the external power source to bidirectional terminal #6 (see Table 6-9). This voltage is sufficient for parameter setting and for keeping the fieldbus active.
Note! If the +24V input of several inverters are connected in parallel, we recommend to use a diode in terminal #6 to avoid the current to flow in opposite direction, which might damage the control board.

The active signal level depends on which potential the common inputs CMA and CMB (terminals 11
and 17) are connected to. The alternatives are either +24V or ground (0 V). See Figure 6-19.
We recommend the use of positive logic in all control connections of the inverter. If negative logic is used, additional appropriate measures are needed to meet the safety regulation requirements.
The 24 volt control voltage and the ground for the digital inputs and the common inputs (CMA, CMB) can be either internal or external.

6.2.2.2 Jumper selections on the OPT-A1 basic board
The user can customise the functions of the inverter to better suit his needs by selecting certain positions for the jumpers on the OPT-A1 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 selection possibilities of the jumpers are shown on page 58 (Figure 6-21).

The control keypad is the link between the Vacon inverter 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 section 7.1.3.
The control information, i.e. the menu number, description of the menu or the displayed value and the numeric information are presented on three text lines.
The inverter is operable through the nine push-buttons of the control keypad. Furthermore, the buttons can be used in setting parameters and monitoring values.
The keypad is detachable and isolated from the input line potential.

Parameters are the way of conveying the commands of the user to the inverter. Parameter values can be edited by entering the
Parameter Menu
from the
Main Menu
when the location indication M2
is visible on the first line of the display. The value editing procedure is presented in Figure 7-1.
Pressing
Menu button right once takes you to the Parameter Group Menu
(G#)
. Locate the desired parameter group by using the
Menu button right again to see the group
and its parameters. Use the
to find the parameter (P#) you want to edit
.
Pressing
You can now change the value in two different ways:
Set the desired value with the Browser buttons
and confirm the change with the
button.
Consequently, the blinking stops and the new value is visible in the value field.
Press
Menu button right once more. Now you will be able to edit the value digit by digit. This may
come in handy, when a relatively greater or smaller value than that on the display is desired.
Confirm the change with the
button.
The value will not change unless the Enter button is pressed. Pressing Menu button left takes
you back to the previous menu.
Several parameters are locked, i.e. cannot be edited, when the drive is in RUN status. If you try to change the value of such a parameter the text
*Locked*
will appear on the display. The inverter must be stopped to edit these parameters.
The parameter values can also be locked using the function in menu M6 (see Chapter6.5.2)).
You can return to the Main menu any time by pressing
Menu button left for 1 to 2 seconds.
The basic application package "All in One+" includes seven applications with different sets of parameters. You will find the parameter lists in the Application Section of this manual.
Once in the last parameter of a parameter group, you can move directly to the first parameter of that group by pressing
See the diagram for parameter value change procedure on page 67.
Note: You can connect power to the control board by connecting the external power source to the
bidirectional terminal #6 on the OPT-A1 board (see page 55). The external power source can also be
connected to the corresponding +24V terminal on any option board. This voltage is sufficient for parameter setting and for keeping the fieldbus active.

Table 7-1. 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' makes the drive stop. Actions need to be taken to restart the drive.
If an 'AR fault' occurs the drive will 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 'FT fault' has basically the same effect as the F fault: the drive is stopped.

8. COMMISSIONING
8.1 Safety
Before commissioning, note the following directions and warnings:
WARNING
1
2
3
4
5
Internal components and circuit boards of the inverter (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-, DC+ terminals are live when
Vacon NX inverter is connected to DC supply, 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 DC supply.
Do not make any connections when the inverter is connected to the DC supply.
After having disconnected the inverter, 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 open the cover before the time has expired.

FAULT
When a fault is detected by the inverter control electronics, the drive is stopped and the symbol F together with the ordinal number of the fault, the fault code and a short fault description appear on
the display. The fault can be reset with the reset
button on the control keypad or via the I/O terminal.
The faults are stored in the Fault history menu M5, which can be browsed. The table below contains all the fault codes.
The fault codes, their causes and correcting actions are presented in the table below. Shadowed faults are A faults only. The items in white on black background present faults for which you can program different responses in the application, see parameter group Protections.
