■Control principle
A frequency converter rectifies AC voltage from
mains into DC voltage, after which this DC
voltage is converted into a AC current with a
variable amplitude and frequency.
VLT® 7000 Booster
The motor is thus supplied with variable voltage and
frequency, which enables infinitely variable speed
control of three-phased, standard AC motors.
1. Mains voltage
3 x 380 - 460 V AC, 50 / 60 Hz.

■AEO - Automatic Energy Optimization
Normally, the U/f characteristics have to be set on the
basis of the expected load at different frequencies.
However, knowing the load at a given frequency in an
installation is often a problem. This problem can be
solved by using a VLT 7000 Booster with its integral
Automatic Energy Optimization (AEO), which ensures
optimum energy utilization. All VLT 7000 Booster
units feature this function as a factory setting, i.e. it
is not necessary to adjust the frequency converter
U/f ratio in order to obtain maximum energy savings.
In other frequency converters, the given load and
voltage/frequency ratio (U/f) must be assessed to carry
out correct setting of the frequency converter.
Using Automatic Energy Optimization (AEO),
you no longer need to calculate or assess the
system characteristics of the installation, since
Danfoss VLT 7000 Booster units guarantee
optimum, load-dependent energy consumption
by the motor at all times.
VLT® 7000 Booster
Booster
Introduction to
The figure on the right illustrates the working
range of the AEO function, within which energy
optimization is enabled.
If the AEO function has been selected in parameter 101,
Torque characteristics, this function will be constantly
active. If there is a major deviation from the optimum U/f
ratio, the frequency converter will quickly adjust itself.
Advantages of the AEO function
• Automatic energy optimization
• Compensation if an oversize motor is used
• AEO matches operations to daily or
seasonal fluctuations
• Energy savings in a constant air volume system
• Compensation in the oversynchronous
working range
• Reduces acoustic motor noise

■PC software and serial communication
Danfoss offers various options for serial communication.
Using serial communication, it is possible to monitor,
program and control one or several frequency
converters from a centrally located computer.
All VLT 7000 Booster units have a RS 485 port
and the FC protocol as standard.
Using the RS 485 port enables communication, e.g.
with a PC. A Windows
TM
program, called MCT 10,is
available for this purpose. It can be used to monitor,
program and control one or several VLT 7000 Booster
units. For further information, contact Danfoss.

■Unpacking and ordering a VLT frequency converter
If you are in doubt as to which frequency converter
you have received and which options it contains,
use the following to find out.
■Type code ordering number string
On the basis of your order, the frequency converter is
given an ordering number that can be seen from the
nameplate on the unit. The number may look as follows:
VLT-7008-B-T4-B20-R3-DL-F00-A33

■Mechanical installation
VLT® 7000 Booster
Please pay attention to the requirements
that apply to integration and field mounting
kit, see the below list. The information given
in the list must be observed to avoid serious damage
or injury, especially when installing large units.
The frequency converter must be installed vertically.
The frequency converter is cooled by means of air
circulation. For the unit to be able to release its cooling
air, the minimum distance over and below the unit
must be as shown in the illustration below.
To protect the unit from overheating, it must be
ensured that the ambient temperature does not rise
above the max. temperature stated for the frequency
converter and that the 24-hour average temperature is
not exceeded . The max. temperature and 24-hour
average can be seen from the General Technical Data.
If the ambient temperature is in the range of 45°C -55°
C, derating of the frequency converter will become
relevant, see Derating for ambient temperature.
The service life of the frequency converter will
be reduced if derating for ambient temperature
is not taken into account.
■Installation of VLT 7002-7072
All frequency converters must be installed in a
way that ensures proper cooling.

■General information about electrical installation
■High voltage warning
The voltage of the frequency converter
is dangerous whenever the equipment is
connected to mains. Incorrect installation
of the motor or the frequency converter may cause
damage to the equipment, serious personal injury
or death. Consequently, the instructions in this
Design Guide, as well as national and local safety
regulations, must be complied with. Touching
the electrical parts may be fatal - even after
disconnection from mains: Using VLT 7002-7005,
380-460 V wait at least 4 minutes
Using VLT 7006-7072, 380-460 V wait at
least 15 minutes
NB!:
It is the user’s or certified electrician’s
responsibility to ensure correct earthing and
protection in accordance with applicable
national and local norms and standards.
■Earthing
The following basic issues need to be considered
when installing a frequency converter, so as to obtain
electromagnetic compatibility (EMC).
to the rear plate. It is necessary to remove insulating
paint or similar from the fastening points.
■Cables
Control cables and the filtered mains cable should
be installed separate from the motor cables so as to
avoid interference overcoupling. Normally, a distance
of 20 cm will be sufficient, but it is recommended
to keep the greatest possible distance wherever
possible, especially where cables are installed in
parallel over a substantial distance.
With respect to sensitive signal cables, such as
telephone cables and data cables, the greatest possible
distance is recommended with a minimum of 1 m per 5
m of power cable (mains and motor cable). It must be
pointed out that the necessary distance depends on
the sensitivity of the installation and the signal cables,
and that therefore no precise values can be stated.
If cable jaws are used, sensitive signal cables are not
to be placed in the same cable jaws as the motor
cable or brake cable. If signal cables are to cross
power cables, this should be done at an angle of
90 degrees. Remember that all interference-filled
in- or outgoing cables to/from a cabinet should
be screened/armoured or filtered.
See also EMC-correct electrical installation.
Installation
• Safety earthing: Please note that the frequency
converter has a high leakage current and must
be earthed appropriately for safety reasons.
Apply local safety regulations.
• High-frequency earthing: Keep the earth wire
connections as short as possible.
Connect the different earth systems at the lowest
possible conductor impedance. The lowest possible
conductor impedance is obtained by keeping the
conductor as short as possible and by using the
greatest possible surface area. A flat conductor, for
example, has a lower HF impedance than a round
conductor for the same conductor cross-section
C
. If more than one device is installed in cabinets,
VESS
the cabinet rear plate, which must be made of
metal, should be used as a common earth reference
plate. The metal cabinets of the different devices
are mounted on the cabinet rear plate using the
lowest possible HF impedance. This avoids having
different HF voltages for the individual devices and
avoids the risk of radio interference currents running
in connection cables that may be used between
the devices. The radio interference will have been
reduced. In order to obtain a low HF impedance, use
the fastening bolts of the devices as HF connection
■Screened/armoured cables
The screen must be a low HF-impedance screen.
This is ensured by using a braided screen of
copper, aluminium or iron. Screen armour int
ended
for mechanical protection, for example, is not
suitable for an EMC-correct installation. See
also Use of EMC-correct cables.
■Extra protection with regard to indirect
contact
ELCB relays, multiple protective earthing or earthing can
be used as extra protection, provided that local safety
regulations are complied with. In
the case of an earth
fault, a DC content may develop in the faulty current.
Never use ELCB relays, type A, since such relays
are not suitable for DC fault curr
ents.
If ELCB relays are used, this must be:
• Suitable for protecting equipment with a direct
current content (DC) in the fault
y current
(3-phase bridge rectifier)
• Suitable for power-up with short charging
current to earth
• Suitable for a high leakage current

■RFI switch
ains supply isolated from earth:
M
When the frequency converter is supplied from an
isolated mains source (IT mains), the RFI switch
must be closed (OFF). In the OFF position, the
internal RFI capacitors (filter capacitors) between
the chassis and the intermediate circuit are cut out
so as to avoid damaging the intermediate circuit
and to reduce the earth leakage currents (see IEC
1800-3). The position of the RFI switch can be
seen from in VLT 7000 enclosures.
Please also refer to the application note VLTon IT mains, MN.90.CX.02.
NB!:
When the RFI switch is set to OFF parameter
407 Switching frequency max is only allowed
to be set to factory setting.
NB!:
TheRFIswitchisnottobeoperatedwith

that the mains supply has been disconnected
before operating the RFI switch.

NB!:
The RFI switch disconnects the capacitors
galvanically; however, transients higher than
approx. 1,000 V will be bypassed by a spark gap.
The VLT 7000 Booster EMC performance
will be reduced if the RFI switch is
placed in the OFF position.

■High voltage test
A high voltage test can be carried out by short-circuiting
terminalsU,V,W,L1,L2andL3andenergizing
by max. 2.5 kV DC for one second between
this short-circuit and the chassis.
NB!:
The RFI switch must be closed (position
ON) when high voltage tests are carried out.
The mains and motor connection must be
interrupted in the case of high voltage tests of the total
installation if the leakage currents are too high.

■EMC-correct electrical installation
Following these guidelines is advised, where
compliance with EN 61000-6-3/4, EN 55011 or
EN 61800-3 First environment is required. If the
installation is in EN 61800-3 Second environment,
then it is acceptable to deviate from these guidelines.
It is however not recommended.
Good engineering practice to ensure EMC-correct
electrical installation:
• Use only braided screened/armoured motor
cables and control cables.
The screen should provide a minimum coverage
of 80%.The screen material must be metal,
not limited to but typically copper, aluminium,
steel or lead. There are no special requirements
for the mains cable.
• Installations using rigid metal conduits are not
required to use screened cable, but the motor
cable must be installed in conduit separate from
the control and mains cables. Full connection
of the conduit from the drive to the motor is
required. The EMC performance of flexible
conduits varies a lot and information from the
manufacturer must be obtained.
• Connect the screen/armour/conduit to earth
at both ends for motor cables and control
cables. See also Earthing of braided screened/
armoured control cables.
• Avoid terminating the screen/armour with tw
ends (pigtails). Such a termination increases the
high frequency impedance of the screen, which
reduces its effectiveness at high frequen
low impedance cable clamps or glands instead.
• Ensure good electrical contact between the
mounting plate and the metal chassis of
the frequency converter.
• Use starwashers and galvanically conductive
installation plates to secure good elec
connections for IP 20 installations.
• Avoid using unscreened/unarmoured motor
or control cables inside cabine
drive(s), where possible.

The illustration shows an example of an EMC-correct
electrical installation of an IP 20 frequency converter.
The frequency converter has been fitted in an
installation cabinet with an output contactor and
connected to a PLC, which in this example is installed
in a separate cabinet. Other ways of making the
installation may have as good an EMC performance,
provided the above guide- lines to engineering practice
are followed. Please note that when unscreened
cables and control wires are used, some emission
