1.1 Warnings

The components of the power unit, LCL filter and pre-charging circuit are live when the
Active Front End is connected to AC 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 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 Active Front End is disconnected from the AC supply.

1.2 Safety Instructions

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

The Active Front End, LCL filter and optional components are used for fixed
installations only.

Do not perform any measurements when the Active Front End is connected to the AC
supply.

After having disconnected the Active Front End from the AC supply, 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 Active
Front End connections. Do not even open the cover before this time has expired.

Do not perform any voltage withstand tests on any part of Active Front End. There is a
certain procedure according to which the tests shall be performed. Ignoring this
procedure may result in damaged product.

Before connecting the Active Front End to AC supply, make sure that the Active Front
End front and cable covers are closed.

Before doing any work on Common DC bus, system shall be earthen.

1.3 Earthing

3.4 Storage

If Vacon® NX Active Front End 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 the Active Front End unit is 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 1hour.

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…500 mA 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*U
shall be supplied at least for 1 hour.

If DC power supply with current limiting is not available and unit has been stored much longer than
1 year de-energized, consult factory before connecting the power.

3.5 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 Vacon
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 Vacon
NX Active Front End. At least the following things should be included in the regular maintenance.

4. ACTIVE FRONT END (AFE)

4.1 Introduction

The Vacon® NX Active Front End is used to transfer power between the AC input and intermediate
DC circuit. The Vacon NX Active Front End has a two-way function. This means that when power is
transferred from the AC input to the intermediate DC circuit, the Vacon NX Active Front End rectifies
the alternating current and voltage. When power is transferred from the intermediate DC circuit to
the AC input, the Vacon NX Active Front End inverts the direct current and voltage.

The difference between Vacon
low current distortion (THDI). In a typical Vacon NX Active Front End configuration, the desired
number of Inverters, Figure 7, are connected to the intermediate DC circuit.

The Active Front End configuration consists of the unit itself, LCL filter, pre-charging circuit, control
unit, AC fuses, main contactor (or circuit-breaker) and DC fuses, Figure 8.

4.7.2 LCL wiring diagram

The LCL filter contains a choke on the mains side, capacitors and a choke on the AFE side,
Figure 16. The LCL also includes capacitors connected against ground potential. There are
resistors connected across the capacitors for discharging them when the LCL filter is disconnected
from the input power. The discharging resistors are 10 MΩ, 500 V and 0,5 W.

4.7.2.1

Removing discharging resistors

If the LCL filter is used in a network fitted with an earth fault protection relay, these discharging
resistors should be removed. If the discharging resistors are not removed, the earth fault
monitoring device might indicate a very low leakage resistance. The resistors must be connected
so that the capacitors are discharged when disconnecting from the input power. The wiring diagram
of an alternative discharging circuit can be seen in Figure 18. Figure 17 shows the default wiring of
the LCL filter. The discharging resistors should be 10 kΩ, 500 V and 2 W. Failure to ensure the
discharging of capacitors results in a risk of electric shock! Without the discharge resistors, the
capacitors take a very long time to discharge.

Figure 19 (for FI9 and FI10) and Figure 20 (for FI13) have a blue marking on the lead that has to be
removed from each capacitor if the discharge resistor is not to be used.

Warning! If you do not allow a total discharge of the system before starting the modification, it is
likely that you will get an electric shock in spite of the fact the system is disconnected from the
power supply.

4.11 Active Front End unit – Fuse selection

4.11.1 Introduction

AC fuses are used to protect the input network in case the Active Front End unit or the LCL filter is
faulty. DC fuses are used to protect the Active Front End unit and the LCL filter in case there is a
short circuit in the DC buses. If DC fuses are not used, short-circuit in the DC buses will cause a
loading of the Active Front End unit. Vacon Plc will not assume any responsibility for damages
caused by insufficient protection.

4.12 Active Front End unit – Circuit breaker selection

The Active Front End can also be protected by a circuit-breaker. The recommended types of circuit­breakers are shown in Table 18. If a circuit-breaker from another manufacturer is used, it must be
equivalent to the circuit-breakers shown. Further information on the circuit-breakers shown is
available from the manufacturer. Circuit-breakers do not provide the same level of protection as
fuses. A circuit-breaker can be used without a main contactor. In this case, the Active Front End unit
controls the circuit-breaker instead of the contactor. The circuit-breakers shown are suitable for
equipment rated at 380 V–500 V or 525 V–690 V.

4.14 Pre-Charging circuit

The Active Front End unit requires an external pre-charging circuit. The purpose of the pre­charging unit is to charge the voltage in the intermediate circuit to a level sufficient for connecting
the Active Front End unit to the mains. The charging time depends on the capacitance of the
intermediate circuit and the resistance of the charging resistors. The technical specifications of
Vacon's standard pre-charging circuits are shown in Table 20. Pre-charging circuits are suitable
for 380-500 Vac and 525-690 Vac.

The Active Front End unit must not be connected to mains without pre-charging. In order to ensure
the correct operation of the pre-charging circuit, the input circuit-breaker or contactor, as well as
the pre-charging circuit contactor, must be controlled by the Active Front End unit. The input
circuit-breaker or contactor as well as the pre-charging circuit contactor must be connected as
shown in Appendix 70.

Table 20. Capacitance Min and Max value for Pre-charging circuit

Capacitance

Frame size Resistance

Min Max

FI9

FI10

FI13

If the capacitance of the intermediate circuit in the system exceeds the values shown, please
contact the nearest Vacon office.

The example shown in Appendix 70 uses a spring-return switch. The switch has positions 0-1­START. The spring returns the switch from position START to position 1. To start the pre-charging,
the switch is turned from position 0 via 1 to START. When pre-charging starts, the switch can be
released and it returns to position 1. No other control measures are required. The Active Front End
application controls the main contactor of the system with Relay Output RO2, see Appendix 72.
When pre-charging of the intermediate circuit is ready the main contactor will be closed. The status
of the main contactor is monitored via digital input (Default is DIN4). As a default the main contactor
monitoring is ON but it can be set OFF with parameter. The main contactor should not be possible
close without pre-charging.

To open the main contactor, simply turn the switch to 0. The contactor should not be opened under
load. Opening the contactor under load will shorten its service life.

NOTE! Wirings what are used for connecting the pre-charging circuit to the intermediate circuit has
to be double insulated.

4.15 Paralleling

The power of the input group can be increased by connecting several Active Front End units in
parallel. Paralleling refers to Active Front End units connected in the same input transformer.
Active Front End units of different power ratings can also be connected in parallel. No
communication bet-ween the units is required; they work independently. Vacon's standard LCL
filters must be used for paralleling. If filters other than Vacon's standard LCL filters are used in
Active Front End units connected in parallel, too large circulation currents may be generated
between the Active Front End units. Parameter P2.1.4
parallel AFE units. This parameter will also set
be also modified manually with parameter P2.2.2.

Each Active Front End unit connected in parallel must have its own short-circuit protection on AC
and DC sides. The fuses are selected in accordance with Section 4.11. When paralleling, attention
must be paid to the sufficient short-circuit capacity of the system.

The derating of Active Front End units connected in parallel is 5% of the DC power; this should be
taken into account when selecting the input unit.

If a device is to be isolated from the AC and DC voltages, and other Active Front End units connected
in parallel are also to be used, separate isolators are required in the AC input and DC output. The
AC input can be isolated using a compact circuit-breaker, an ordinary circuit-breaker or a fuse
switch. Contactors are not suitable for isolating the AC input because they cannot be locked in the
safe position. The DC output can be isolated using a fuse switch. The pre-charging circuit must also
be isolated from the AC input. A load isolation switch or safety isolation switch can be used for this.
The device can also be connected to mains even when the other devices connected in parallel are
already connected and running. In such a case, the isolated deice must first be pre-charged. When
that is done, the AC input can be switched on. After this, the device can be connected to the
interediate DC circuit.

4.15.1 Common pre-charging circuit

In case of paralleled Active Front End units, one common pre-charging circuit can be used, see
Figure 21. Standard pre-charging circuits can be used if the capacitance of the intermediate circuit
not exceeds maximum value. For example if three FI10 Active Front End units are connected
parallel, the pre-charging circuit for FI13 Active Front End unit can be used. If all paralleled Active
Front End units have a common circuit breaker, the breaker can be controlled by one of the Active
Front End units. If each paralleled Active Front End unit has its own circuit-breaker, each Active

Front End controls it’s own circuit. The circuit diagram for control, see Appendix 70 and Appendix

72.

4.15.2 Each Active Front End unit has the pre-charging circuit

Each Active Front End can have its own pre-charging circuit. Each unit controls its own pre-charging
and main contactor. See Figure 22. One control switch can be used, but if an Active Front End unit
needs to be controlled independently, separate switches are needed. With this the system is more
redundant than with a common pre-charging circuit. The circuit diagram for control, see Appendix
70 and Appendix 72.

The output power has to be derated if one of following cases:

• Ambient temperature is more than 40 ºC.

• Installation altitude is more than 1000 m.

4.16.1 Ambient Temperature

The power rating of the Active Front End unit is valid for an ambient temperature of 40 ºC. If the
device is to be used in higher ambient temperatures, its power rating must be subjected to derating.
The derating coefficient is 1.5%/1 ºC, for ambient temperatures not exceeding 50 ºC. The reduced
power is calculated using the formula:

Pde = P

5.2.3 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 22 and
Table 24 must be followed. For instance, there could be two screened gaps as presented in
Figure 39 (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 unit
frame is given in Table 22 and Table 24. The cooling arrangements inside the cabinet must be such
that they prevent hot output air from mixing with the incoming fresh air (see Chapter 5.2.4).

The ventilation gaps must fulfill 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. In case of LCL filter air inlet 1.1 in Figure 39
cannot be used.

5.2.4 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 Figure 40).

B. Install shields in the gaps between the power unit and the cabinet walls (B in Figure 40).

Place the shields above the air outlet gaps at the sides of the module.

NOTE! If a flat roof is used, mount a V-shaped air guide on the underside of the roof to direct the air
flow horizontally. See Figure 41.

5.3 Power connection

5.3.1 AC connection

The 3-phase input is connected to the input terminals of the LCL filter (L1, L2 and L3). The output
terminals of the LCL filter (U, V and W) are connected to the input terminals of the AFE unit (U, V
and W), Figure 8. The AC input of the AFE input group must be protected against short circuit. The
fuses suitable for protection are shown in Chapter 4.11. A circuit breaker can also be used for
protection, see Chapter 4.12. The best short-circuit protection is achieved by using fuses. The
short-circuit protection must be on the input side when seen from the LCL filter, Figure 8.

A cable or busbar designed for the purpose must be used to make the connection. The connection
must be dimensioned according to the nominal current rating of the Active Front End unit. The
necessary overloading allowance must also be used. The connection must also have the same
short-circuit capacity as the whole system. The connecting cable or busbar may be of copper or
aluminium. When aluminium is used, steps must be taken to prevent corrosion. The dimensions of
the terminals in the unit are indicated in Appendix 82 and their locations are shown in Appendix 73,
Appendix 74 and Appendix 75. Locations of terminals in the LCL filter are shown in Appendix 76 and
Appendix 77.

5.3.2 DC connection

The DC connection of the Active Front End unit is connected to the terminals at the top. The
terminals are marked as B+ for connection to DC+ and B- for connection to DC-. The DC connection
must be protected using DC fuses, see Chapter 4.11. The terminal dimensions are shown in
Appendix 82.

5.3.3 LCL filter Fan power supply

Two types of power supplies are available for the LCL filter cooling fan. The cooling fan can be
supplied from an external power supply or an integrated DC/DC power supply.

5.3.3.1 LCL filter with integrated DC/DC power supply for fan

The DC/DC power supply is integrated in the structure of the LCL filter, Figure 44 and Figure 45.
The integrated DC/DC power supply takes its input voltage from the intermediate circuit,
Appendix 79. The input of the DC/DC power supply must be protected against short circuit using DC
fuses type Ferraz Shawmut ATQ8 (8 A) if the length of the supply cable does not exceed 2 m. The
fuses can be installed in holders type Ferraz Shawmut US102I (2-pole), to allow the easy
disconnection of the DC/DC power supply from the supply. If the length of the supply cable exceeds
2 m, fuses type Ferraz Shawmut D100gRB008VI (8 A) must be used. The fuses should be installed
in holders.

The high DC voltage must be taken into account when wiring the supply; suitable cables/leads must
be used.

The DC/DC power supply is monitored and controlled by the Active Front End unit. The DC/DC power
supply connections are shown in Figures 44 - 45 and Appendix 79 and Appendix 80.

5

The control connection has to be taken from the Active Front End unit. The control cable has to be
connected to the terminal X51 on the LCL filter, see Figure 44 and Figure 45. The control cable has
to be connected to the terminal X3 on the Active Front End unit, see Figure 47. The terminal X3 can
be found under the black cover. In the FI13, the terminal X3 is located in the left-most unit. The
delivery includes the cable for the control connection. The length of the standard cable is 1,6 m.

The over-temperature protection can be wired directly to the control unit or to the DC/DC power
supply. The over-temperature protection must be connected to protect the filter for protect the
filter in case of over-temperature.

NOTE! By default, the over-temperature protection is not activated. If it is not activated, the LCL can
be damaged in case of over-temperature.

If the over-temperature protection is connected to a digital input, the wires have to be removed from
the terminal X52. The I/O wiring has to be connected to the terminals 1 and 4 on the terminal X52,
see Appendix 80. If the over-temperature protection is connected to the I/O of the Active Front End
unit, it can be programmed. The parameter P2.2.1.3 has to be set to choose the digital input to which
the over-temperature monitoring is connected. The parameter P2.7.3 allows one to select the
response to an over-temperature alarm as wanted.

If the over-temperature protection is connected to the DC/DC power supply, the jumper has to be
removed from the terminal X3. The cable from the terminal X52 should be connected to the terminal
X3. By default, the jumper is connected to the terminal X3, see Figure 45. The delivery includes the
cable for connecting the terminals X52 and X3. The wiring diagram can be seen in Appendix 80. If
over-temperature monitoring is connected to the DC/DC power supply, the Active Front End unit
will monitor over-temperature. The response to an over-temperature alarm cannot be selected. In
this case, the over-temperature fault message will be same as the fan fault of the unit. On the
keypad, the fault “32 Fan Cooling” will be shown.

LCL filter without DC/DC power supply for fan

The LCL filter is supplied without an integrated DC/DC power supply. In this case, the customer
must procure the power supply separately. The requirements for the DC power supply are shown
in Table 2. Short-circuit protection is implemented by protecting the input of the DC power with
fuses. When required, the cooling fan can be controlled on/off by installing a contactor in the DC
power supply input and controlling that depending on whether the main switch is open or closed.

The over-temperature protection of the LCL filter must always be wired from contacts 1 and 4 of
terminal X52 to a digital input of the control unit (see Appendix 81) and from contacts 1 and 2 of
terminal X51 to a digital input of the control unit. The wiring of the circuit is shown in Figure 48.

When Vacon® NX Active Front End 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 (+24 V) by connecting the external power source to
bidirectional terminal #6. This voltage is sufficient for parameter setting and for keeping the
fieldbus active.

NOTE! If the +24 V input of several brake choppers or other loads 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.

6.3.5 Fault types

®

Vacon

NX Active Front End has four types of faults. These types differ from each other on the basis

of the subsequent behaviour of the drive. See Table 26.

Figure 57. Fault display

Table 26. Fault types

Fault type symbol Meaning

A

(Alarm)

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.

F

(Fault)

AR

(Fault Autoreset)

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.

FT

(Fault Trip)

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.
