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.
NB! With the IP 21 solution all units require a minimum of 100 mm air on each side. This means that side-by-side mounting is NOT allowed.

Table 1.3: Tightening of terminals.

Power Cables
NB! Please note that the power terminals can be removed.
Connect mains to the mains terminals of the frequency converter, i.e. L1, L2 and L3 and the earth connection to terminal 95.


Fit screened/armoured cable from the motor to the motor terminals of the frequency converter, i.e. U, V, W. The screen ends in a screen connector.

Mains connection
NB! Please note that at 1 x 220-240 Volt the neutral wire must be attached to terminal N (L2) and the phase wire must be connected to terminal L1 (L1).

NB! Please check that the mains voltage fits the mains voltage of the frequency converter, which can be seen from the nameplate.
400-Volt units with RFI-filters may not be connected to mains supplies in which the voltage between phase and earth is more than 300 Volts. Please note that for the IT mains and the delta earth the mains voltage can exceed 300 Volts between phase and earth. Units with type code R5 (IT mains) can be connected to mains supplies with up to 400 V between phase and earth.
See Technical data for correct dimensioning of cable cross-section. See also the section entitled Galvanic isolation in the Operating Instructions for further details.

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.

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 motor characteristics [8] when motors are connected in parallel.

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 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.

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).

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.

NB! Please note that the cable jacket for the relay must cover the first row of control card terminals - otherwise the galvanic isolation (PELV) cannot be maintained. Max. cable diameter: 4 mm.

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.

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.

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.

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.

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 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 frequency converter.

Table 1.4: Prefuses for UL application /cUL

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.

Programming

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.

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 parameters. See Menu mode.
[STOP/RESET] is used for stopping the connected motor or for resetting the frequency converter after a trip.

NB! Use MCT-10 and USB to RS485 converter to change parameters.

Warnings/alarm messages


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.

Special Conditions

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, cabinet fitting with fresh-air circulation in the cabinet is recommended, thereby ensuring that aggressive gases are kept away from the frequency converter.
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.

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.

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.

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).

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).

Derating for High Switch Frequency
The frequency converter will automatically derate the rated output current I_VLT,N, when the switching frequency exceeds 4.5 kHz.
In both cases, the reduction is carried out linearly, down to 60% of I_VLT,N.

Safety

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.

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. 10mm† 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.

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.

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.

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.
