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 dis-
connected from mains.Also make sure that other voltage inputs have been discon-
nected (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 de-
layed) 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 func-
tion 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 dis-
connect 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 pre-
scribed 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 per-
sonal safety considerations make it necessary to ensure that no unintended start oc-
curs, 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 con-
nection 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 moni-
toring 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.

All types of three-phase asynchronous standard motors can be connected to a frequency con-
verter. 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.

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.
NB!
If an unscreened/unarmoured cable is used, some EMC requirements are not com-
plied 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 con-
verter 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, I
M, 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 con-
verter 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.

1.4.9 Earthing
Comply with the following at installation:
• Safety earthing: The drive has a high leakage current and must be earthed properly for
safety. Follow all local safety regulations.
• High frequency earthing: Keep earthing connections as short as possible.

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.
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 ca-
ble 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, pro-
vided 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 in-
stallation, switch gear, machines etc., must be short-circuited and overcurrent protected according
to national/international regulations.
Short circuit protection:
Danfoss recommends using thefuses 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 fre-
quency 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 A
rms
(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 fre-
quency 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 inter-
mediate 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.

1.5 Programming
1.5.1 Control Unit
On the front of the frequency converter there
is a control panel divided into four sections.
1. Six-digit LED display.
2. Keys for changing parameters and
shifting display function.
3. Indicator lamps.
4. Keys for local operation.
LED indication
Warning yellow
Alarm red
Trip locked yellow and red
All displays of data are in the form of a six-digit LED display capable of showing one item of
operating data continuously during normal operation. As a supplement to the display, there are
three indicator lamps for indication of mains connection (ON), warning (WARNING) and alarm
(ALARM). Most of the frequency converter's parameter Setups can be changed immediately via
the control panel, unless this function has been programmed as
Locked [1] via parameter 018
Lock for data changes .
1.5.2 Control Keys
[QUICK MENU] allows access to the parameters used for the Quick menu.
The[QUICK MENU] key is also used if a change to a parameter value is not to be implemented.
See also [QUICK MENU] + [+].
[CHANGE DATA] is used for changing a setting.
If the display shows three dots at the right, the parameter value has more than three digits. In
order to see the value, activate [CHANGE DATA]
The [CHANGE DATA] key is also used for confirming a change of parameter settings.
[+] / [-] are used for selecting parameters and for changing parameter values.
These keys are also used in Display mode for selecting the display of an operating value.
The [QUICK MENU] + [+] keys must be pressed at the same time to give access to all param-
eters. See
Menu mode.
[STOP/RESET] is used for stopping the connected motor or for resetting the frequency converter
after a trip.
Can be selected as
Active [1] or Not active [0] via parameter 014 Local stop/reset . In Display
mode, the display will flash if the stop function is activated.

NB!
If the [STOP/RESET] key is set at
Not active [0] in parameter 014 Local stop/re-
set,
and there is no stop command via the digital inputs or serial communication,
the motor can only be stopped by disconnecting the mains voltage to the frequency
converter.
[START] is used for starting the frequency converter. It is always active, but the [START] key
cannot override a stop command.
1.5.3 Manual initialisation
Disconnect mains voltage. Hold the [QUICK MENU] + [+] + [CHANGE DATA] keys down while
simultaneously reconnecting the mains voltage. Release the keys; the frequency converter has
now been programmed for the factory setting.
1.5.4 Display Readout States
In normal operation, one item of operating data can be displayed continuously at the operator's
own choice. By means of the [+/-] keys the following options can be selected in Display mode:
• Output frequency [Hz]
• Output current [A]
•Outputvoltage[V]
• Intermediate circuit voltage [V]
•Outputpower[kW]
• Scaled output frequency f
out
x p008
1.5.5 Menu mode
In order to enter the Menu mode [QUICK MENU] + [+] must be activated at the same time.
In Menu mode, most of the frequency converter parameters can be changed. Scroll through the
parameters using the [+/-] keys. While scrolling in the Menu mode proceeds, the parameter
number will flash.
1.5.6 Quick menu
Using the [QUICK MENU] key, it is possible to access the 12 most important parameters of the
frequency converter. After programming, the frequency converter is in most cases ready for op-
eration. When the [QUICK MENU] key is activated in Display mode, the Quick menu starts. Scroll
through the quick menu using the [+/-] keys and change the data values by first pressing
[CHANGE DATA] and then changing the parameter value with the [+/-] keys.
The Quick menu parameters are shown in section
Parameter Lists .

1.5.7 Hand Auto
During normal operation the frequency converter is in Auto mode, where the reference signal is
given externally, analog or digital via the control terminals. However, in Hand mode, it is possible
to give the reference signal locally via the control panel.
On the control terminals, the following control signals will remain active when Hand mode is ac-
tivated:
Hand Start (LCP2) Quick Stop Inverse Thermistor
Off Stop (LCP2) Stop Inverse Precise Stop Inverse
Auto Start (LCP2) Reversing Precise Stop/Start
Reset DC Braking Inverse Jog
Coasting Stop Inverse Setup Select LSB Stop Comm. Via Serial Comm.
