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 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.
The inverter has a large capacitive leakage current.
4
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

1.3 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.

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.

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).

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.

5.2 Fan cooling
5.2.1
Frames FR4 to FR8
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 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. When planning the cooling for the space, take into consideration that the inverter’s heat loss is 2.5% of the nominal capacity.

Power losses as function of switching frequency
Raising the switching frequency of the drive, to reduce motor noise for example, inevitably affects the power losses and cooling requirements as shown in the Figure below. It illustrates the power loss FR7 as function of switching frequency. For more information, contact the Manufacturer or your local distributor (see back cover).

Power connections
6.1.1.1
DC supply and motor cables
The power cables are connected to terminals DC+ and DC- (R+/B+ and DC terminals when using an external charging circuit) and the motor cables to terminals U, V and W. A cable entry gland should
be used at the motor cable end to reach the EMC levels, see Table 6-1.
Use cables with a heat resistance of at least +60C. The cables and the fuses must be sized according to the inverter nominal output current which you can find 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.
The minimum dimensions of the Cu-cables are shown in Table 6-4.
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 installations with one motor and one cable connection from the inverter to the motor. In any other case, ask the factory for more information.

Before starting the installation, check that none of the components of the inverter are live.
If the inverter is installed outside the cubicle, cabinet or device space,
you need to install a separate inverter cover (see, for example Figure 6-3
) in accordance with protection class IP21 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 (units with power greater than 1.5 kW) and 100 m (units with power from 0.75
to 1.5 kW).
The motor cables should cross other cables at an angle of 90 degrees.

6.2 Control unit
The control unit of the inverter consists of the control board and option boards (see Figure 6-7 and
Figure 6-20) connected to the five slot connectors (A to E) on the control board. The control board is connected to the power unit through a D connector (1).
A

C
D
E board
When the inverter is delivered from the factory, the control unit usually includes two basic boards
(I/O board and relay board), which are normally installed in slots A and B. On the next pages you will
find the arrangement of the control I/O and the relay terminals of the two basic boards, the general
wiring diagram and the 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.

Digital input signal inversions
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 6-13.
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.

Jumper selections on the NXOPTA1 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 NXOPTA1 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 43 (Figure 6-15).

CONTROL KEYPAD
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.

Note: You can connect power to the control board by connecting the external power source to the
bidirectional terminal #6 on the NXOPTA1 board (see page 40). 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.

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.

HMI acknowledge timeout (P6.7.3)
This function allows the user to change the timeout of the HMI acknowledgement time. The inverter waits for the HMI acknowledgment in accordance with the value of this parameter.
Note! If the inverter has been connected to the PC with a normal cable, the default values of parameters 6.7.3 and 6.7.4 (200 and 5) must not be changed.
If the inverter has been connected to the PC via a modem and there is a delay in transferring messages, the value of parameter 6.7.3 must be set according to the delay as follows:
Example:
Transfer delay between the inverter 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.

COMMISSIONING
8.1 Safety
Before commissioning, note the following directions and warnings:
WARNING
HOT SURFACE
1
2
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-link/brake resistor terminals+/are live when Vacon NX inverter is connected to DC supply, even if the motor is not running.
3
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 Vacon NX is disconnected from DC supply.
Do not make any connections when the inverter is connected to the DC supply.
5
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.
6 Before connecting the inverter to DC supply make sure that the Vacon NX front cover is closed.
7
When running, the side of inverter FR8 is burning hot. Do not touch it with bare hands!
8 When running, the back of inverter FR6 is burning hot. Therefore it MUST
NOT be mounted onto a surface which is not fireproof.
8.2 Commissioning the inverter
1
Read carefully the safety instructions in Chapter 1 and above and follow them.
2
After the installation, make sure that: both the inverter and the motor are grounded
the DC supply and motor cables comply with the requirements given in Chapter 6.1.1.
the control cables are located as far as possible from the power cables (see Chapter 6.1.2,
step 2) and the shields of the shielded cables are connected to protective earth . The wires may not touch the electrical components of the inverter.
