1. SAFETY

ONLY A COMPETENT ELECTRICIAN MAY CARRY OUT

THE ELECTRICAL INSTALLATION

1.1 Warnings

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.

WARNING

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 cables from the frequency converter.

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

1.2 Safety instructions

The components of the power unit of the frequency converter and all cabinet mounted devices are potentially 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 –/+ and all other mains devices are potentially 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 cabinet door before this time has expired.

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 as well as the cabinet doors are closed.

6 • vacon SAFETY

1.3 Earthing and earth fault protection

The Vacon NX frequency converter must always be earthed with an earthing conductor connected to the PE bar in the lower front side of the cabinet.

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 symbols

For your own safety, please pay special attention to the instructions marked with the following symbols:

3.3 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

Relative humidity <95%, no condensation

The environment should also be free from dust. If there is dust in the air the converter should be well protected to make sure dust does not get into the converter.

If the converter is to be stored during longer periods the 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.

3.4 Maintenance

In normal conditions, Vacon NX frequency converters are maintenance-free. However, we recommend to keep the converter clean, e.g. by cleaning the heatsink with compressed air whenever necessary.

In IP54 units, the air filters in the door and in the roof should be cleaned or replaced regularly.

It is recommended to replace the fans every 6 years.

We recommend checking the tightening torques of terminals at regular intervals.

Vacon Service Centre can provide you with a long-period maintenance plan for your frequency converter on request.

3.5 Warranty

Only manufacturing defects are covered by the warranty. The manufacturer assumes no responsibility for damages caused during or resulting from transport, receipt of the delivery, installation, commissioning or use.

The manufacturer shall in no event and under no circumstances be held responsible for damages and failures resulting from misuse, wrong installation, unacceptable ambient temperature, dust, corrosive substances or operation outside the rated specifications.

Neither can the manufacturer be held responsible for consequential damages.

The Manufacturer's time of warranty is 18 months from the delivery or 12 months from the commissioning whichever expires first (Vacon Warranty Terms).

The local distributor may grant a warranty time different from the above. This warranty time shall be specified in the distributor's sales and warranty terms. Vacon assumes no responsibility for any other warranties than that granted by Vacon itself.

5.2 Lifting the unit out of the transport packaging

The unit is delivered either in a wooden box or a wooden cage. The box may be transported either horizontally or vertically, while transportation of the cage in a horizontal position is not allowed. To lift the unit out of the box, use lifting equipment capable of handling the weight of the cabinet.

There are lifting lugs on the top of the cabinet and these lugs can be used to lift the cabinet into an upright position and to move it to the place needed.

Min 60°

Figure 5-2. Lifting the unit

Recycle the packaging material according to local regulations.

5.3 Fixing the unit to the floor or to the wall

The cabinet should always be fixed to the floor or to the wall. Depending on installation conditions, the cabinet sections can be fixed in different ways. There are holes in the front corners which can be used for fixing. Additionally, the rails on the top of the cabinet have fixing lugs for fixing the cabinet to the wall.

Welding of the cabinet might risk sensitive components in the converter.

Ensure that no grounding currents can flow through any part of the converter.

5.3.1 Fixing to the floor and to the wall

In installations where the cabinet is mounted against the wall, it is more convenient to fix the top of the cabinet to the wall. Fix the cabinet in the two front corners to the floor with bolts. Fix the top part to the wall with bolts. Note that the rails and the fixing lugs can be moved horizontally to make sure the cabinet stands in a horizontal position. In converters consisting of more than one cabinet section, fix all sections in the same way.

Figure 5-3. Fixing the cabinet to the floor and to the wall

5.3.2 Fixing to the floor only

Note: This option is not available for FR13 and bigger units.

If bottom-only fixing is used, additional fixing brackets (Rittal part.nr. 8800.210) or equivalent are necessary. Fix the cabinet to the floor in the front with bolts and use the fixing brackets in the middle. Fix all cabinet sections in the same way.

5.4 AC choke connections

The AC input choke carries out several functions in the Vacon NX frequency converter. The input choke is needed as an essential component for motor control, to protect the input and DC-link components against abrupt changes of current and voltage as well as to function as a protection against harmonics.

The frequency converter is equipped with one or more input AC chokes. The chokes have two inductance levels to optimise the functionality at different supply voltages. In the installation phase, the wiring of the chokes should be checked and changed if needed (not for FR9).

The input is always connected to terminal #1 (see picture below) and should not be changed. The output of the choke should be connected to terminal #2 or #3 (see picture below) according to the table below. The terminals are marked with inductance values and applicable voltage.

In units FR10 to FR12, the connection is changed by moving the cable to the appropriate terminals.

In FR13/14, the bridges of the busbar connection should be moved according to the settings shown in the table.

WARNING

In units with two or more parallel chokes (some FR11 as well as all FR12 and FR13) all chokes have to be wired in the same way. If chokes are wired differently the converter may be damaged.

5.5 Auxiliary voltage transformer tappings

If the drive is ordered with an auxiliary voltage transformer for 230V auxiliary voltage supply (+ATx option) the tappings of the transformer have to be set according to the mains voltage.

The tappings of the transformer in 500V drives is by default set to 400V and in 690V drives to 690V unless otherwise ordered.

Locate the transformer in the lower part of the cabinet. The primary side of the transformer has tappings that correspond to standard main voltages. Change to tapping to correspond to the mains voltage in use.

5.7 Power losses

The power loss of the frequency converter varies greatly with load and output frequency as well as with the switching frequency used.

6.1 Understanding the power unit topology

Figure 6-1 shows the principles for mains and motor connections of the basic 6-pulse drive in frame sizes FR10 to FR14.

Some units built in frame size FR11 have double input devices and require an even number of supply cables but an uneven number of motor cables can be used.

Units built in frame size FR12 consist of two power modules and require an even number of supply and ables. See Figure 6-1 and tables 6-2 and 6-4.

The 12-pulse drives always have a double set of inputs. The motor connection is size dependent as described above and in Figure 6-1.

6.2 Power connections

6.2.1 Mains and motor cables

The mains cables are connected to terminals L1, L2 and L3 (12-pulse units 1L1, 1L2, 1L3, 2L1, 2L2,

2L3) and the motor cables to terminals marked with U, V and W, see Figure 6-3.

In converters consisting of double input sections (some FR11 and all FR12 units), an even number of input cables is required. In converters consisting of double power modules (FR12) an even number of input cables and an even number of motor cables is needed. See tables 6-2 to 6-5 for cabling recommendations.

WARNING

In 12-pulse units and in types with double inputs (FR11 and FR12) or outputs (FR12) is it very important that the same cable dimensions, type and routing is used for all cables. In case the cabling between the converter modules is not symmetrical, unequal load inside converter might reduce loadability or even damage the converter.

In units with double motor outputs the motor cables must not be connected together in the converter end. Always connect the parallel motor cables together in the motor end only.

The minimum motor cable length is 5m.

WARNING

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 in front of the AC choke as shown in the figure below.

The EMC grounding clamps must be suited to the output cable diameter to give a 360 o

contact with the cables. Refer to chapters 6.2.4 and 6.2.5 for output cable diameters. See Figure 6-2.

EMC grounding

PE rail Cable fixing clamps

Figure 6-2. Installing EMC grounding

For more detailed cable installation instructions, see chapter 7, step 6.

Use cables with a temperature rating of at least +70

C. As a rule of thumb, cables and the fuses can 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 the output current.

Tables 6-2 and 6-4 show the minimum dimensions of Cu- and Al-cables and the recommended aR fuse sizes.

If the motor temperature protection of the drive (see Vacon All in One Application Manual) is used as an overload protection, the cable should be chosen accordingly. If three or more cables are used parallelly (per block) in bigger units each cable requires a separate overload protection.

Installing the cable gland

Unless the cable gland is already installed by the manufacturer, follow the procedure below to do this:

1. Assemble the rubber sealing in the narrow groove of the bush ring. Make sure that the gap between the assembly plate and the sealing is tight.

2. Since the fastening spring is rather stiff, we recommend to use a cone-shaped tool to fit the metal sock in the bush ring and then to clamp it with the spring bent into a ring shape. Draw the sock over the groove far enough to be easily fastened with the spring. Make sure that the spring clamps the sock at 360°.

3. Roll up the sock as far as the fastening ring and remove the cone-shaped tool if used. Now the cable installation is easier and the cable will not damage the sock.

4. Clamp the sock to the shielding of cable with a cable tie.

6.2.1.2 Installation of ferrite rings (+OCM) on the motor cable

Modern PWM Frequency converters based on IGBT transistors generate output pulses having short rise times (0,1...0,2 µs). Those pulse edges increase the stress for motor insulation and also generate high frequency common mode voltages on the motor output. Common mode voltage increases emitted radio interferences and might cause danger of bearing currents when larger motor frames

(> 100kW) are used.

Motor cable selection and installation has to be done according to the requirements of the installation environment. The screen of the motor cable has to be connected to earth at every end (frequency converter, safety switch, motor etc.) so that high frequency impedance is as low as possible.

The best solution is a 360-degree grounding. If this is difficult to do then connect the PE conductor to ground or panel wall (metallic) right after the stripping point of jacket of cable (see Figure 6-8, alternatives a and b). Influence of common mode voltages can easily be additionally attenuated by installing a common mode choke on the motor output. The simplest way is to use ferrite rings with a diameter large enough to allow the motor phase conductors to be slipped through.

Installation of the ferrite rings:

Slip only the phase conductors through the rings; leave the cable screen below and outside the rings, see Figure 6-8. Separate the PE conductor. In case of parallel motor cables, reserve an equal amount of ferrite ring sets for each cable and feed all the phase conductors of one cable through one set of rings.

Vacon's delivery consists of fixed sets of ferrite rings (option). When ferrite rings are used to attenuate the risk of bearing damages, use always two ferrite ring sets per motor cable.

Note! The ferrite rings are only additional protection. The basic protection against bearing currents is an insulated bearing.

6.2.2 DC supply and brake resistor cables

Vacon frequency converters can optionally be equipped with terminals for DC supply and with an 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– on the converter module. The converter module terminals can also optionally be wired to customer terminals in the cabinet.

WARNING

Make sure that the converter is equipped with a brake chopper before connecting a brake resistor.

WARNING

Do not connect the brake resistor between the terminals B- and B+ as this will damage the drive.

6.2.3 Control cable

For information on control cables see chapter 7.2. The control cables are routed down to the bottom of the cabinet in the left inner side of the cabinet.

6.2.4 Cable and fuse sizes, 380-500V units

The table below shows typical cable sizes and types that can be used with the converter. The final selection should be made according to local regulations, cable installation conditions and cable specification.

7. INSTALLATION INSTRUCTIONS

Before starting the installation, check that none of the components of the frequency converter is live.

Make sure that the space where the converter is installed, and the converter itself, is clean and free from particles, dust or humidity that could harm the converter when it is powered on.

Make sure the connection of the AC choke and the optional 230V auxiliary voltage transformer are suitable for the supply voltage in use (See chapters 5.4 and 5.5).

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 run 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 maximum length of the motor cables is 300m.

If output du/dt filters (+DUT option) are used the cable length is limited according to the table below:

Maximum cable length with du/dt filter

Connect the cables:

Strip the motor and mains cables

Remove the protection grids for the input terminals and the protection covers on the converter module(s).

Pull the cable through the bottom plate and fix the PE conductor to the PE bar of the cabinet.

Connect the mains, motor and control cables into their respective terminals. Use cable lugs on the power cables. In units with parallel cables (FR11 and FR12) make sure the cabling is fully symmetrical.

Fix the shields of the motor cable(s) to the cabinet by using the earthing clamps included in the delivery.

For Information on cable installation according to UL regulations see Chapter 7.1.

Make sure that the control cable wires do not come in contact with the electronic components of the unit or control components inside the cabinet.

If an external brake resistor (option) is used, connect its cable to the appropriate terminal (R+/R–). Also make sure that the converter is equipped with a brake chopper (indicated in the type code of the converter).

Check the connection of the earth cable to the motor and the frequency converter terminals marked with PE or .

Connect the separate shield of the power cable to the earth terminals of the frequency converter, motor and the supply centre.

IMPORTANT: If an output filter (+ODU, +OSI) is used, note that the switching frequency of the converter (parameter 2.6.9, ID601) must be set according to the specification of the output filter. Setting too high/low a switching frequency may damage the filter.

7.1 Cable installation and the UL standards

To meet the UL ( Underwriters Laboratories ) regulations, a UL-approved copper cable with a minimum heat-resistance of +60/75

C must be used. The cable must be suitable for use on a circuit capable of delivering not more than 100,000 rms symmetrical amperes, 600V maximum. Use Class 1 wire only.

The tightening torques of the terminals are given in Table 7-1.

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. Brake resistor cable insulation checks

Disconnect the brake resistor cable from terminals R+ and R- of the frequency converter and from the brake resistor. Measure the insulation resistance of the cable between each conductor as well as between conductors and the protective ground conductor.

The insulation resistance must be >1MΩ.

4. 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.

5. Brake resistor insulation check

Disconnect the brake resistor cable and measure the insulation from the power terminals to the ground terminal. The measurement voltage must equal at least the motor nominal voltage but not exceed 1000 V. The insulation resistance must be >1MΩ.

7.2 Control unit

The control unit of the frequency converter consists roughly of the control board and additional boards (see

Figure 7-1 and Figure 7-2) 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.

Figure 7-1. NX control board Figure 7-2. 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

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, ±10%) by connecting the external power source to either of the bidirectional terminala #6 or #12, see page 42. This voltage is sufficient for parameter setting and for keeping the fieldbus active.

Note! If the 24V 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.

8. 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.

8.3.2 Parameter menu (M2)

Parameters are the way of conveying the commands of the user to the frequency converter. The 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 8-5.

Push the Menu button right once to move into the

Parameter Group Menu (G#)

. Locate the parameter group desired by using the Browser buttons and push the Menu button right again to enter the group and its parameters. Use again the

Browser buttons to find the parameter

(P#)

you want to edit. From here you can proceed in two different ways: Pushing the

Menu button right

takes you to the edit mode. As a sign of this, the parameter value starts to blink. You can now change the value in two different manners:

1

Just set the new desired value with the

Browser buttons and confirm the change with the

Enter button

. Consequently, the blinking stops and the new value is visible in the value field.

2

Push the

Menu button right once again. Now you will be able to edit the value digit by digit. This editing manner may come in handy, when a relatively greater or smaller value than that on the display is desired. Confirm the change with the

Enter button

The value will not change unless the Enter button is pushed. Pressing the

Menu button left

takes you back to the previous menu.

Several parameters are locked, i.e. uneditable, 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 frequency converter must be stopped in order to edit these parameters.

The parameters values can also be locked using the function in menu M6 (see Chapter Parameter lock (P6.5.2)).

You can return to the

Main menu

anytime by pressing the

Menu button left

for 3 seconds.

The basic application package "All in One" includes seven applications with different sets of parameters. See the All in One Application manual for closer information.

Once in the last parameter of a parameter group, you can move directly to the first parameter of that group by pushing the Browser button up

The keypad reference submenu (P3.2) displays and allows the operator to edit the frequency reference. The changes will take place immediately. This reference value will not, however, influence the rotation speed of the motor unless the keypad has been selected as source of reference.

NOTE: The maximum difference in RUN mode between the output frequency and the keypad reference is 6 Hz.

See Figure 8-5 for how to edit the reference value (pressing the

Enter button

is not, however, necessary).

8.3.3.3 Keypad direction

The keypad direction submenu displays and allows the operator to change the rotating direction of the motor. This setting will not, however, influence the rotation direction of the motor unless the keypad has been selected as the active control place.

See Figure 8-6 for how to change the rotation direction.

Note: Additional information on controlling the motor with the keypad is given in Chapters 8.2.1 and

9.2.

8.3.3.4 Stop button activated

By default, pushing the STOP button will always stop the motor regardless of the selected control place. You can disable this function by giving parameter 3.4 the value 0. If the value of this parameter is 0, the STOP button will stop the motor only when the keypad has been selected as the active control place.

NOTE! There are some special functions that can be performed when in the

M3

menu:

start

Select the keypad as the active control place by keeping the button pushed down for 3 seconds when the motor is running. The keypad will become the active control place and the current frequency reference and direction will be copied to the keypad.

stop

Select the keypad as the active control place by keeping the button pushed down for 3 seconds when the motor is stopped. The keypad will become the active control place and the current frequency reference and direction will be copied to the keypad.

Copy the frequency reference set elsewhere (I/O, fieldbus) to the panel by keeping the

enter

button pushed down for 3 seconds.

Note that if you are in any other than M3 menu these functions will not work.

If you are in some other than

(Fault Autoreset)

(Fault Trip)

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.

8.3.6.3 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

to the keypad, then the keypad is connected to another drive and then the parameter groups are

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:

Parameter sets (S6.3.1)

The Vacon NX frequency converter features a possibility for the user to load back the factory default parameter values and to store and load two customised parameter sets (all parameters included in the application).

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 8.3.6.3.

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.

8.3.6.4 Parameter comparison

In the

Parameter comparison

submenu (S6.4), you can compare the actual parameter values to the values of your customised parameter sets and those loaded to the control keypad.

The comparison is performed by pushing the Menu button right when in the

Compare parameters submenu

. The actual parameter values are first compared to those of the customised parameter

Set1. If no differences are detected a '0' is displayed on the lowermost line. But if any of the parameter values differ from those of the Set1 the number of the deviations is displayed together with symbol P (e.g. P1ÆP5 = five deviating values). By pressing the

Menu button right

once again you can still enter the pages where you can see both the actual value and the value it was compared to.

In this display, the value on the Description line (in the middle) is the default value and the one on the value line (lowermost) is the edited value. Furthermore, you can also edit the actual value with the Browser buttons in the

Fan control (P6.7.2)

This function allows you to control the frequency converter’s cooling fan. You can set the fan to run continuously when the power is switched on or depending on the temperature of the unit. If the latter function has been selected the fan is switched on automatically when the heat sink temperature reaches 60°C or the converter is in RUN state. The fan receives a stop command when the heat sink 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

9. COMMISSIONING

9.1 Safety

Before commissioning, note the following directions and warnings:

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.

WARNING

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 cabinet door or cover before this time has expired.

HOT SURFACE

Before connecting the frequency converter to mains make sure that the

Vacon NX front cover is closed.

9.2 Commissioning of the frequency converter

Read carefully the safety instructions in Chapter 1 and above and follow them.

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 6.2.2.

- that the control cables are located as far as possible from the power cables (see

Chapter 7, 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 +24V or ground of the

I/O terminal or the external supply.

Check the quality and quantity of cooling air (chapter 5.2 and Table 5-2).

Check the inside of the frequency converter for condensation.

Check that all Start/Stop switches connected to the I/O terminals are in Stop-position.

Connect the frequency converter to mains.
