■Use on isolated mains
See section RFI Switch regarding use on isolated mains.
It is important to follow the recommendations regarding
installation on IT-mains, since sufficient protection
of the complete installation must be observed.
Not taking care using relevant monitoring devices
for IT-mains may result in damage.
It is the responsibility of the user or the
person installing the VLT to provide proper
earthing/grounding, as well as motor
overload and branch circuit protection according to
local codes such as the Nation Electrical Code (NEC).
NB!:
Electrostatic Precaution; Electrostatic discharge
(ESD). Many electronic components are
sensitive to static electricity. Voltages so low
that they cannot be felt, seen or heard, can reduce
the life, affect performance, or completely destroy
sensitive electronic components. When performing
service, proper ESD equipment should be used to
prevent possible damage from occurring.

■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®8000 AQUA
The motor is thus supplied with variable voltage and
frequency, which enables infinitely variable speed
control of three-phased, standard AC motors.

■Example of application - Constant pressure
regulation in water supply system
The demand for water from waterworks varies considerably during the course of a day. In the night,
practically no water is used, while in the morning and in the evening the consumption is high. In order to
maintain a suitable pressure in the water supply lines in relation to the current demand, the water supply
pumps are equipped with speed control. The use of a frequency converter enables the energy consumed by
the pumps to be kept at a minimum, while optimizing the water supply to consumers.
A VLT 8000 AQUA with its integral PID controller ensures simple and quick installation. For example, an
IP54/NEMA 12 unit can be mounted close to the pump on the wall and the existing mains cables can be
used as mains supply to the frequency converter. A Pressure transmitter (e.g. Danfoss MBS 33 or MBS
3000) can be fitted a few meters (feet) from the joint outlet point from the waterworks to obtain closed loop
regulation. Danfoss MBS 33 and MBS 3000 is a two-wire transmitter (4-20 mA) that can be powered directly
from a VLT 8000 AQUA. The required setpoint (e.g. 5 bar) can be set locally in parameter 418 Setpoint 1.
Assume:
Transmitter is scaled 0-10 Bar, minimum flow
is achieved at 30 Hz. An increase in motor
speed increases the pressure.

■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 8000 AQUA units have an RS 485 port as
standard with a choice of two protocols. The protocols
selectable in parameter 500 protocols are:
• FC Protocol
• Modbus RTU
A bus option card allows higher transmission speed
than RS 485. In addition, a higher number of units
can be linked to the bus and alternative transmission
media can be used. Danfoss offers the following
option cards for communication:
• Profibus
• LonWorks
• DeviceNet
Information on the installation of various options is
not included in these operating instructions.
Using the RS 485 port enables communication,
TM
e.g. with a PC. A Windows
program, called
MCT 10, is available for this purpose. It can be
used to monitor, program and control one or
several VLT 8000 AQUA units.
■PC Software tools

Introduction
■Fieldbus options
The increasing need for information in building
management systems makes it necessary to collect
or visualise many different types of process data.
Important process data can help the system technician
in the day to day monitoring of the system, which
means that a negative development, e. g. an increase
in energy consumption, can be rectified in time.
The substantial amount of data in large buildings
may generate a need for a higher transmission
speed than 9600 baud.
MG.83.A2.02 - VLT is a registered Danfoss trademark
■Profibus
Profibus is a fieldbus system with FMS and DP,
which can be used for linking automation units,
such as sensors and actuators, to the controls
by means of a two-conductor cable.
Profibus FMS is used if major communication
tasks are to be solved at cell and system level by
means of large volumes of data.
Profibus DP is an extremely fast communication
protocol, made specially for communication between
the automation system and various units.
VLT 8000 AQUA only supports DP.
13
■LON - Local Operating Network
LonWorks is an intelligent fieldbus system which
improves the possibility of decentralising control,
as communication is enabled between individual
units in the same system (Peer-to-Peer).
This means that there is no need for a big main station
for handling all the signals of the system (Master-Slave).
Signals are sent direct to the unit that needs them
via a common network medium. This makes
communication much more flexible and the central
building state control and monitoring system can be
changed into a dedicated building state monitoring
system whose task is to ensure that everything is
running as planned. If the potential of LonWorks is
fully utilised, sensors will also be connected to the
bus, which means that a sensor signal can quickly
be moved to another controller. If room dividers are
mobile, this is a particularly useful feature.
■DeviceNet
DeviceNet is a digital, multi-drop network, based
on the CAN protocol, that connects and serves
as a communication network between industrial
controllers and I/O devices.
Each device and/or controller is a node on the
network. DeviceNet is a producer-consumer
network that supports multiple communication
hierarchies and message prioritization.
DeviceNet systems can be configured to operate in a
master-slave or a distributed control architecture using
peer-to-peer communication. This system offers a
single point of connection for configuration and control
by supporting both I/O and explicit messaging.
DeviceNet also has the feature of having power
on the network. This allows devices with limited
power requirements to be powered directly from
the network via the 5-conductor cable.
VLT®8000 AQUA
■Modbus RTU
MODBUS RTU (Remote Terminal Unit) Protocol is
a messaging structure developed by Modicon in
1979, used to establish master-slave/client-server
communication between intelligent devices.
MODBUS is used to monitor and program
devices; to communicate intelligent devices
with sensors and instruments; to monitor field
devicesusingPCsandHMIs.
MODBUS is often applied in Gas and Oil applications,
but also in building, infrastructure, transportation and
energy, applications are making use of its benefits.

■Cascade Controller Option
In "Standard Mode", one motor is controlled by
the drive that has the Cascade Controller Option
card installed in it. Up to four additional fixed speed
motors can be sequenced on & off, as required
by the process, in lead-lag mode.
In "Master/Slave Mode", the drive that has the
Cascade Controller option card installed in it, along
with its associated motor, is designated as the
master. Up to four additional motors, each with
its own drive, can be operated in slave mode. The
Cascade Controller functions to stage the slave
drives/motors - on & off (as required), as a function
of "best system operating efficiency".
In "Lead Pump Alternation Mode", it is possible to
averageouttheusageofthepumps.Thisisdoneby
making the frequency converter switch between the
pumps (max. 4) by means of a timer. Please note
that this mode requires an external relay setup.
VLT®8000 AQUA
This filter reduces the voltage rise time, the peak voltage
and the ripple currentI to the motor, thereby
U
PEAK
making current and voltage almost sinusoidal. The
acoustic motor noiseis thereforereducedto a minimum.
Because of the ripple current in the coils, there will be
some noise from the coils. This problem can be solved
entirely by integrating the filter in a cabinet or similar.
Introduction
Consult your Danfoss Sales Office for
additional information.
■LC filters for VLT 8000 AQUA
When a motor is controlled by a frequency converter,
resonance noise will be heard from the motor. This
noise, which is caused by the design of the motor,
occurs each time one of the inverter switches in
the frequency converter is activated. Consequently,
the resonance noise frequency corresponds to the
switching frequency of the frequency converter.
For the VLT 8000 AQUA, Danfoss offers a LC filter
to dampen the acoustic motor noise.
■Examples of the use of LC filters
ubmersible pumps
S
For small motors with up to and including 5.5 kW
rated motor power, use an LC filter, unless the motor
is equipped with phase separation paper. This applies
e.g. to all wet running motors. If these motors are
used without LC filter in connection with a frequency
converter, the motor windings will short-circuit. If in
doubt, ask the motor manufacturer whether the motor
in question is equipped with phase separation paper.
ell pumps
W
If immersion pumps are used, e.g. submerged
pumps or well pumps, the supplier should be
contacted for clarification of requirements. It is
recommended to use a LC filter if a frequency converter
is used for well pump applications.

■Harmonic filter
Harmonic currents do not directly affect the electricity
consumption but has an impact on following conditions:
Higher total current to be handled by the installations
- Increases load on transformer (sometimes it will
require a larger transformer, particular at retrofit)
- Increases heat losses in transformer and installation
- In some cases demands larger cables,
switches and fuses
Higher voltage distortion due to higher current
- Increase risk for disturbing electronic equipment
connected to same grid
A high percentage of rectifier load from eg frequency
converters, will increase the harmonic current, which
must be reduced to avoid the above consequences.
Therefore the frequency converter has as standard,
built in DC coils reducing the total current with about
40% (compared to devices without any arrangement
for harmonic suppression), down to 40-45% ThiD.
In some cases there is a need for further suppression
(eg retrofit with frequency converters). For this purpose
Danfoss can offer two advanced harmonic filters
AHF05 and AHF10, bringing the harmonic current
down to around 5% and 10% respectively. For further
details see instruction MG.80.BX.YY.
MCT 31
The MCT 31 harmonic calculation PC tool enables
easy estimation of the harmonic distortion in a given
application. Both the harmonic distortion of Danfoss
frequency converters as well as non-Danfoss frequency
converters with different additional harmonic reduction
measurements, such as Danfoss AHF filters and
12-18-pulse rectifiers, can be calculated.

tool using code number 130B1031.
