1.1 Safety
1.1.1 Warnings
High Voltage Warning:
The voltage of the frequency converter is dangerous whenever it is connected to
mains. Incorrect installation of the motor or frequency converter may cause damage
to the equipment, serious injury or death. Consequently, it is essential to comply
with the instructions in this manual as well as local and national rules and safety
regulations.
Warning:
Touching the electrical parts may be fatal - even after the equipment has been disconnected from mains.Also make sure that other voltage inputs have been disconnected (linkage of DC intermediate circuit). Be aware that there may be high voltage
on the DC link even when the LEDs are turned off. Before touching any potentially
live parts of the frequency converter, wait at least 4 minutes.
Leakage Current:
The earth leakage current from the frequency converter exceeds 3.5 mA. According
to IEC 61800-5-1 a reinforced Protective Earth connection must be ensured by
means of a min. 10mm² Cu or an addtional PE wire - with the same cable cross
section as the Mains wiring - must be terminated separately.
To increase safety, install an RCD
Residual Current Device:
This product can cause a DC current in the protective conductor. Where a residual
current device (RCD) is used for extra protection, only an RCD of Type B (time delayed) shall be used on the supply side of this product. See also Danfoss Application
Note on RCD, MN.90.GX.YY.
Protective earthing of the frequency converter and the use of RCDs must always
follow national and local regulations.
Motor Thermal Protection:
Protection against Motor overload is not included in the factory setting. If this function is required, set par. 128 Motor Thermal Protection to data value ETR trip or data
value ETR warning. For the North American market: The ETR functions provide
overload protection of the motor, class 20, in accordance with NEC.
Installation in high altitudes:
For altitudes above 2 km, please contact Danfoss regarding PELV.

1.1.2 Safety Instructions
•
The frequency converter must be disconnected from the mains if repair work is to be
carried out. Check that the mains supply has been disconnected and the prescribed time
has passed before removing motor and mains plugs.
•
Make sure the frequency converter is properly connected to earth.
•
Protect users against supply voltage.
•
Protect the motor against overloading according to national and local regulations.
•
The earth leakage current exceeds 3.5 mA. For ELCB types, please see application note
MN.90.GX.YY.
•
The [STOP/RESET] key on the control panel of the frequency converter does not disconnect the equipment from mains and is thus not to be used as a safety switch.
•
Note that the frequency converter has more voltage inputs than L1, L2 and L3 when DC
bus terminals are used. Check that all voltage inputs are disconnected and that the prescribed time has passed before repair work is commenced.
1.1.3 Warning against unintended start
1.
The motor can be brought to a stop by means of digital commands, bus commands,
references or a local stop, while the frequency converter is connected to mains. If personal safety considerations make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient.
2.
While parameters are being changed, the motor may start. Consequently, the stop key
[STOP/RESET] must always be activated, following which data can be modified.
3.
A motor that has been stopped may start if faults occur in the electronics of the frequency
converter, or if a temporary overload or a fault in the supply mains or the motor connection ceases.
1.1.4 Use on Isolated Mains
See section RFI Switch in the operating instructions 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.

1.2.3 Approvals
1.2.4 Disposal Instruction
Equipment containing electrical components must not be disposed of
together with domestic waste.
It must be separately collected with electrical and electronic waste
according to local and currently valid legislation.
1.3 Mechanical Installation
VLT 2800 frequency converters allow side-by-side installation on a wall in any position as the units
do not require ventilation on the side. Because of the need for cooling, there must be 10 cm free
air passage above and below the frequency converter.
All units with enclosure IP 20 must be integrated in cabinets and panels. IP 20 is not suitable for
remote mounting. In some countries, e.g. in the USA, units with enclosure NEMA 1 are approved
for remote mounting.

1.4.4 Motor connection
Connect the motor to terminals 96, 97, 98. Connect earth to terminal 99.
See Technical data for correct dimensioning of cable cross-section.
All types of three-phase asynchronous standard motors can be connected to a frequency converter. Normally, small motors are star-connected (230/400 V, Δ/ Y).
NB!
In motors without phase insulation paper, an LC filter should be fitted on the output
of the frequency converter.
The factory setting is for clockwise rotation.
The direction of rotation can be changed by switching two phases on the motor terminals.
1.4.5 Parallel connection of motors
The frequency converter is able to control several motors connected in parallel.
Please consult the Operating Instructions for further information.
NB!
Be aware that the total cable length, listed in the section EMC Emission.
NB!
Parameter 107 Automatic motor adaption, AMT cannot be used when motors are
connected in parallel. Parameter 101 Torque characteristic must be set to Special

1.4.6 Motor Cables
See General Specifications for correct dimensioning of motor cable cross-section and length. See
EMC Emissions for relationship between length and EMC emission.
Always comply with national and local regulations on cable cross-section.
1
NB!
If an unscreened/unarmoured cable is used, some EMC requirements are not complied with, see EMC test results in the Design Guide.
If the EMC specifications regarding emission are to be complied with, the motor cable must be
screened/armoured, unless otherwise stated for the RFI filter in question. It is important to keep
the motor cable as short as possible so as to reduce the noise level and leakage currents to a
minimum. The motor cable screen must be connected to the metal cabinet of the frequency converter and to the metal cabinet of the motor. The screen connections are to be made with the
biggest possible surface area (cable clamp). This is enabled by different installation devices in
different frequency converters. Mounting with twisted screen ends (pigtails) is to be avoided, since
these spoil the screening effect at high frequencies. If it is necessary to break the screen to install
a motor isolator or motor relay, the screen must be continued at the lowest possible HF impedance.
1.4.7 Motor Thermal Protection
The electronic thermal relay in UL-approved frequency converters has received the UL-approval
for single motor protection, when parameter 128 Motor thermal protection has been set for ETR
Trip and parameter 105 Motor current, IM, N has been programmed to the rated motor current
(see motor nameplate).
1.4.8 Control Cables
Remove the front cover underneath the control panel. Place a jumper between terminals 12 and
27.
Control cables must be screened/armoured. The screen must be connected to the frequency converter chassis by means of a clamp. Normally, the screen must also be connected to the chassis
of the controlling unit (use the instructions for the unit in question). In connection with very long
control cables and analogue signals, in rare cases depending on the installation, 50/60 Hz earth
loops may occur because of noise transmitted from mains supply cables. In this connection, it may
be necessary to break the screen and possibly insert a 100 nF capacitor between the screen and
the chassis.
See section entitled Earthing of screened/armoured control cables in the VLT 2800 Design Guide
for the correct termination of control cables.

VLT 2800 Quick Guide
1 Quick Guide
Connect all earthing systems to ensure the lowest possible conductor impedance. The lowest
possible conductor impedance is achieved by keeping the conductor as short as possible and by
grounding with the greatest possible surface area. If multiple drives are installed in a cabinet, the
cabinet backplate, which must be made of metal, should be used as a joint earth reference plate.
The drives must be fitted to the backplate at the lowest possible impedance.
1
To achieve low impedance, connect the drive to the backplate with the drive fastening bolts. The
backplate must be completely free from paint.
1.4.10 EMC emission
The following system results are achieved on a system consisting of a VLT Series 2800 with
screened/armoured control cable, control box with potentiometer, screened/armoured motor cable and screened/armoured brake cable as well as an LCP2 with cable.

1.4.11 Extra protection
RCD relays/ELCBs, multiple protective earthing or earthing can be used as extra protection, provided that local safety regulations are complied with.
Three phase VLT frequency converters require an RCD type B. If an RFI filter is mounted in the
drive and either the switch of the RCD or a manually operated switch is used to connect the drive
to the mains voltage, a time delay of minimum 40 ms is required (RCD type B).
If no RFI filter is mounted of a CI contactor is used for mains connection, no time delay is required.
Single phase VLT frequency converters require an RCD type A. There is no particular need for a
time delay whether RFI filters are mounted or not.
See application note MN.90.GX.YY for further information on ELCBs.
1.4.12 EMC-correct electrical installation
General points to be observed to ensure EMC-correct electrical installation.
-
Use only screened/armoured motor cables and screened/armoured control cables.
-
Connect the screen to earth at both ends.
-
Avoid installation with twisted screen ends (pigtails), since this ruins the screening effect
at high frequencies. Use cable clamps instead.
-
It is important to ensure good electrical contact from the installation plate through the
installation screws to the metal cabinet of the frequency converter.
-
Use starwashers and galvanically conductive installation plates.
-
Do not use unscreened/unarmoured motor cables in the installation cabinets.
The illustration below shows EMC-correct electrical installation, in which the frequency converter
has been fitted in an installation cabinet and connected to a PLC.

1.4.13 Fuses
Branch circuit protection:
In order to protect the installation against electrical and fire hazard, all branch circuits in an installation, switch gear, machines etc., must be short-circuited and overcurrent protected according
to national/international regulations.
Short circuit protection:
Danfoss recommends using the fuses mentioned in the following table to protect service personnel
or other equipment in case of an internal failure in the unit or short-circuit on DC-link. The frequency converter provides full short circuit protection in case of a short-circuit on the motor or
brake output.
Overcurrent protection:
Provide overload protection to avoid overheating of the cables in the installation. Overcurrent
protection must always be carried out according to national regulations. Fuses must be designed
for protection in a circuit capable of supplying a maximum of 100,000 Arms (symmetrical), 480 V
maximum.
Non UL compliance:
If UL/cUL is not to be complied with, Danfoss recommends using the fuses mentioned in the below
table, which will ensure compliance with EN50178/IEC61800-5-1:
In case of malfunction, not following the fuse recommendation may result in damage to the frequency converter.

1.4.14 RFI switch
Mains supply isolated from earth:
If the frequency converter is supplied from an isolated mains source ( IT mains) or TT/TN-S mains
with grounded leg, the RFI switch is recommended to be turned off (OFF). For further reference,
see IEC 364-3. In case optimum EMC performance is needed, parallel motors are connected or
the motor cable length is above 25 m, it is recommended to set the switch in ON position.
In OFF position, the internal RFI capacities (filter capacitors) between the chassis and the intermediate circuit are cut off to avoid damage to the intermediate circuit and to reduce the earth
capacity currents (according to IEC 61800-3).
Please also refer to the application note VLT on IT mains, MN.90.CX.02. It is important to use
isolation monitors that are capable for use together with power electronics (IEC 61557-8).
NB!
The RFI switch is not to be operated with mains connected to the unit. Check that
the mains supply has been disconnected before operating the RFI switch.
The RFI switch disconnects the capacitors galvanically from ground.
The switch Mk9, placed next to terminal 96, should be removed to disconnect the RFI-filter.
The RFI switch is only available on VLT 2880-2882.

W: Warning, A: Alarm, T: Trip locked
A warning or an alarm will appear in the display as a numerical code Err. xx. A warning will be
shown on the display until the fault has been corrected, while an alarm will continue to flash until
the [STOP/RESET] key is activated.The table shows the various warnings and alarms, and whether
the fault locks the frequency converter. After a Trip locked the mains supply is cut off and the
fault is corrected. The mains supply is reconnected and the frequency converter is reset. The
frequency converter is now ready. A Trip can be reset manually in three ways:
1.
Via the operating key [STOP/RESET].
2.
Via a digital input.
3.
Via serial communication.
It is also possible to choose an automatic reset in parameter 405 Reset function. When a cross
appears in both warning and alarm, this can mean that a warning comes before an alarm. It can
also mean that it is possible for the user to programme whether a warning or an alarm will appear
for a given fault. For example, this is possible in parameter 128 Motor thermal protection. After a
trip the motor will coast, and alarm and warning will blink on the frequency converter, but if the
fault disappears only the alarm will blink. After a reset the frequency converter will be ready to
start operation again.

Safeguards:
•
Electronic thermal motor protection against overload.
•
Temperature monitoring of the power module ensures that the frequency converter cuts
out if the temperature reaches 100 °C. An overload temperature cannot be reset until
the temperature of the power module is below 70 °C.
1.12 Special Conditions
1.12.1 Aggressive Environments
The frequency converter is not to be installed in environments, where liquids, particles or gases are in the air that would impact and damage the electronics. Unless
the necessary measures are taken to protect the frequency converter, there is a risk
of stoppages, which reduce the service life of the frequency converter.
Aggressive gases, such as sulphur, nitrogen and chlorine compounds, together with high humidity
and temperature, facilitate possible chemical processes on the components of the frequency converter. These chemical processes quickly impact and damage the electronics. In these areas,

VLT 2800 Quick Guide
1 Quick Guide
cabinet fitting with fresh-air circulation in the cabinet is recommended, thereby ensuring that
aggressive gases are kept away from the frequency converter.
1
NB!
Fitting of frequency converters in aggressive environments increases the risk of
stoppages, in addition to considerably reducing the service life of the unit.
Before the frequency converter is installed, it must be checked whether there are liquids, particles
or gases in the air. This can be done by looking at existing installations in the same environment.
Typical indicators of harmful airborne liquids are water or oil on metal parts or corrosion of metal
parts. Too many dust particles are typically observed on top of installation cabinets and on existing
electrical installations. Indicators that there are aggressive gases in the air are copper rails and
cable ends that are black on existing electrical installations.
1.12.2 Derating for Ambient Temperature
The ambient temperature measured over 24 hours should be at least 5° C lower than the max.
ambient temperature.
If the frequency converter is operated above 45° C, the continuous output current should be
decreased.
1.12.3 Derating for Low Air Pressure
Above 1000 m the ambient temperature or max. output current must be derated.
For altitudes above 2000 m, please contact Danfoss regarding PELV.
1.12.4 Derating for Running at Low Speeds
When a motor is connected to at frequency converter, it is necessary to check that the cooling of
the motor is adequate.
A problem may occur at low speeds in constant torque applications. Running continuously at low
speeds – below half the nominal motor speed – may require additional air cooling. Alternatively,
choose a larger motor (one size up).
1.12.5 Derating for Long Motor Cables
The frequency converter has been tested using a 75 m unscreened/unarmoured cable and a 25
m screened/armoured cable and has been designed to work using a motor cable with a rated
cross-section. If a cable with a larger cross-section is required, it is recommended to reduce the
output current by 5% for each step the cable cross-section is increased. (Increased cable crosssection leads to increased capacitance to earth, and thus to an increased earth leakage current).
1.12.6 Derating for High Switch Frequency
The frequency converter will automatically derate the rated output current IVLT,N, when the switching frequency exceeds 4.5 kHz.
In both cases, the reduction is carried out linearly, down to 60% of IVLT,N.
