Mechanical installation

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 adjustable frequency drive

must

be installed vertically.

The adjustable frequency drive 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 adjustable frequency drive and that the 24-hour average temperature is not exceeded

. The max. temperature and 24-hour average can be seen from the General Technical section.

When installing the adjustable frequency drive on a non flat surface, i.e. a frame, please consult the instruction, MN.50.XX.YY.

If the ambient temperature is in the range of 45° C

— 55° C, derating of the adjustable frequency drive will be required in accordance with the diagram in the Design Guide. The service life of the adjustable frequency drive will be reduced if no allowance is made for the derating for ambient temperature.

All units require a minimum space above and below the enclosure.

General information about electrical installation

High voltage warning

The voltage of the AFD is dangerous whenever the equipment is connected to line. Incorrect installation of the motor or the AFD may cause damage to the equipment, serious personal injury or death. Consequently, the instructions in this manual, as well as national and local safety regulations, must be complied with. Touching the electrical parts may be fatal even after disconnection from line:

Using VLT 8006-8062, 200-240 V wait at least 15 minutes

Using VLT 8006-8072, 380-480 V wait at least 15 minutes

Using VLT 8102-8352, 380-480 V wait at least 20 minutes

Using VLT 8450-8600, 380-480 V wait at least 15 minutes

Using VLT 8002-8006, 525-600 V wait at least 4 minutes

Using VLT 8008-8027, 525-600 V wait at least 15 minutes

Using VLT 8032-8300, 525-600 V wait at least 30 minutes

■

If more than one device is installed in cabinets, the cabinet rear plate, which must be made of metal, should be used as a common ground 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 to the rear plate. It is necessary to remove insulating paint or similar from the fastening points.

Cables

Control cables and the filtered line cable should be installed separate from the motor cables so as to avoid interference overcoupling. Normally, a distance of

204mm (8 in) 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.

NOTE

It is the user ’ s or certified electrician ’ s responsibility to ensure correct grounding and protection in accordance with applicable national and local codes and standards.

With respect to sensitive signal cables, such as telephone cables and data cables, the greatest possible distance is recommended with a minimum of 1m (3 ft) per 5m (15 ft) of power cable (line 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.

■

Grounding

The following basic issues need to be considered when installing an AFD.

• Safety grounding:

Please note that the

AFD has a high leakage current and must be grounded appropriately for safety reasons.

Apply local safety regulations.

• High-frequency grounding:

Keep the ground wire connections as short as possible.

Connect the different ground 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

VESS

.

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 shielded/armored or filtered.

■

Shielded/armored cables

The shield must be a low HF-impedance shield. This is ensured by using a braided shield of copper, aluminium

50

MG.80.A6.22 — VLT is a registered Danfoss trademark

or iron. Shield armor intended for mechanical protection, for example, is not suitable.

■

Extra protection with regard to indirect contact

ELCB relays, multiple protective grounding or grounding can be used as extra protection, provided that local safety regulations are complied with. In the case of an ground 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 currents.

If ELCB relays are used, this must be:

•

Suitable for protecting equipment with a direct current content (DC) in the faulty current

(3-phase bridge rectifier)

•

Suitable for power-up with short charging current to ground

•

Suitable for a high leakage current

RFI switch

Mains supply isolated from earth:

If the adjustable frequency drive is supplied from an isolated mains source (IT mains and grounded delta), the RFI switch can be turned off (OFF). 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).

NOTE

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.

NOTE

Open RFI switch is only allowed at factory set switching frequencies.

NOTE

The RFI switch disconnects the capacitors galvanically to ground.

The red switches are operated by means of e.g. a screwdriver. They are set in the OFF position when they are pulled out and in ON position when they are pushed in (see drawing below). Factory setting is ON.

EMC-correct electrical installation

525-600 V units do not comply with European

EMC and Low Voltage Directives.

The following is a guideline to good engineering practice, when installing drives. Following these guidelines is advised, where compliance with EN 50081,

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. See also

CE labelling,

Emission

and

EMC test results

in this manual.

Good engineering practice to ensure EMC-correct electrical installation:

•

Use only braided shielded/armored motor cables and braided shielded/armored control cables. The shield should provide a minimum coverage of 80%.

The shield material must be metal, not limited to but typically copper, aluminum, steel or lead. There are no special requirements for the line cable.

•

Installations using rigid metal conduits are not required to use shielded cable, but the motor cable must be installed in conduit separate from the control and line 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 shield/armor/conduit to ground at both ends for motor cables as well as for control cables. See also

Grounding of braided shielded/armored control cables

.

•

Avoid terminating the shield/armor with twisted ends (pigtails). Such a termination increases the high frequency impedance of the shield, which reduces its effectiveness at high frequencies.

Use low impedance cable clamps or EMC cable glands instead.

•

It is important to have good electrical contact between the mounting plate on which the AFD is installed and the metal chassis of the AFD unit.

Exception:

IP54/NEMA 12 units designed for wall mounting

VLT 8152-8600 (380-480 V) IP20/NEMA 1

VLT 8042-8062 (200-240 V) IP20/NEMA 1

This however does not apply to IP54/NEMA 12 units as they are designed for wall mounting and

VLT 8152-8600, 380-480 VAC and VLT 8042-8062,

200-240 VAC in IP20/NEMA 1 enclosure.

VLT® 8000 AQUA

•

Use starwashers and galvanically conductive installation plates to secure good electrical connections for IP00/Chassis and IP20/NEMA

1 installations.

•

Avoid using unshielded/unarmored motor or control cables inside cabinets housing the drive(s), whenever this can be avoided.

•

An uninterrupted high frequency connection between the AFD and the motor is required for IP54/NEMA 12 units.

The next illustration shows an example of an

EMC-correct electrical installation of an IP 20/NEMA

1 AFD; the AFD has been installed in a cabinet

(enclosure) together with an output contactor and is connected to a PLC which, in this example, is installed in a separate cabinet. For IP 54/NEMA 12 units, VLT

8152-8600 (380-480 V) and VLT 8042-8062 (200-240

V) units in IP20/NEMA 1 enclosures; shielded cables are connected by using EMC conduits to assure proper

EMC performance. (See next illustration.)

Other ways of making the installation may give as good an EMC performance, provided the above engineering practice guidelines are followed.

Please note, that when the installation is not made according to these guidelines as well as when unshielded cables and control wires are used, some emission requirements are not complied with, although the immunity requirements are fulfilled.

Earthing/Grounding of shielded/armored control cables

Generally speaking, control cables must be shielded/ armored and the shield must be connected by means of a cable clamp at both ends to the metal cabinet of the unit.

The drawing below indicates how correct earthing/grounding is carried out.

Correct earthing/grounding

Control cables and cables for serial communication must be fitted with cable clamps at both ends to ensure the best possible electrical contact.

Wrong earthing/grounding

Do not use twisted cable ends (pigtails), since these increase the shield impedance at high frequencies.

Protection with respect to ground potential between PLC and AFD

If the ground potential between the AFD and the PLC

(etc.) is different, electric noise may occur that will disturb the whole system. This problem can be solved by fitting an equalizing cable, to be placed next to the control cable. Minimum cable cross-section: 8 AWG.

For 50/60 Hz ground loops

If very long control cables are used, 50/60 Hz ground loopsmay occur that will disturb the whole system. This problem can be solved by connecting one end of the shield to via a ground 100nF capacitor (keeping leads short).

Cables for serial communication

Low-frequency noise currents between two AFD can be eliminated by connecting one end of the shield to terminal 61. This terminal is connected to ground via an internal RC link. It is recommended to use twisted-pair cables to reduce the differential mode interference between the conductors.

Use of EMC-correct cables

Braided shielded/armored cables are recommended to optimise EMC immunity of the control cables and the EMC emission from the motor cables.

The ability of a cable to reduce the in- and outgoing radiation of electric noise depends on the transfer impedance (Z

T

). The shield of a cable is normally designed to reduce the transfer of electric noise; however, a schield with a lower transfer impedance

(Z

T

) value is more effective than a shield with a higher transfer impedance (Z

T

).

Transfer impedance (Z

T

) can be assessed on the basis of the following factors:

The conductibility of the shield material.

The contact resistance between the individual shield conductors.

The shield coverage, i.e. the physical area of the cable covered by the shield — often stated as a percentage value.

Shield type, i.e. braided or twisted pattern.

Aluminium-clad with copper wire.

Twisted copper wire or armoured steel wire cable.

Single-layer braided copper wire with varying percentage shield coverage.

This is the typical Danfoss reference cable.

Double-layer braided copper wire.

Twin layer of braided copper wire with a magnetic, shielded/armored intermediate layer.

Cable that runs in copper tube or steel tube.

Lead cable with 1.1 mm wall thickness.

Transfer impedance (Z

T

) is rarely stated by cable manufacturers, but it is often possible to estimate transfer impedance (Z

T

) by assessing the physical design of the cable.

All types of three-phase asynchronous standard motors can be used with a VLT 8000 AQUA unit.

The direction of rotation can be changed by switching two phases in the motor cable.

■

Parallel coupling of motors

Small-size motors are normally star-connected.

(220/380 V, /Y). Large-size motors are delta-connected (380/660 V, /Y). The correct connection and voltage can be read from the motor nameplate.

NOTE

In older motors without phase coil insulation, a

LC filter should be fitted to the AFD output.

VLT 8000 AQUA is able to control several motors connected in parallel. If the motors are to have different rpm values, the motors must have different rated rpm values. Motor rpm is changed simultaneously, which means that the ratio between the rated rpm values is maintained across the range.

70

MG.80.A6.22 — VLT is a registered Danfoss trademark

The total current consumption of the motors is not to exceed the maximum rated output current I

VLT,N for the AFD.

Problems may arise at the start and at low rpm values if the motor sizes are widely different. This is because the relatively high ohmic resistance in small motors calls for a higher voltage at the start and at low rpm values.

In systems with motors connected in parallel, the electronic thermal relay (ETR) of the AFD cannot be used as motor protection for the individual motor. Consequently, additional motor protection is required, such as thermistors in ground motor

(or individual thermal relays).

If it is necessary to break the shield to install a motor isolator or motor contactor, the shield must be continued at the lowest possible HF impedance.

■

Motor cables

See

Technical data

for correct sizing of motor cable cross-section and length.

Always comply with national and local regulations on cable cross-sections.

NOTE

If an unshielded cable is used, some

EMC requirements are not complied with, see

EMC test results

.

If the EMC specifications regarding emission are to be complied with, the motor cable must be shielded, 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 shield must be connected to the metal cabinet of the AFD and to the metal cabinet of the motor. The shield connections are to be made with the biggest possible surface (cable clamp).

This is enabled by different installation devices in the different AFDs. Mounting with twisted shield ends (pigtails) is to be avoided, since these spoil the shielding effect at higher frequencies.

Bus connection

The serial bus connection in accordance with the RS

485 (2-conductor) norm is connected to terminals

68/69 of the AFD (signals P and N). Signal P is the positive potential (TX+,RX+), while signal N is the negative potential (TX-,RX-).

If more than one AFD is to be connected to a given master, use parallel connections.

In order to avoid potential equalizing currents in the shield, the cable shield can be grounded via terminal

61, which is connected to the frame via an RC-link.

Bus termination

The bus must be terminated by a resistor network at both ends. For this purpose, set switches 2 and 3 on the control card for «ON».

Control unit LCP

The front of the AFD features a control panel — LCP

(Local Control Panel). This is a complete interface for operation and programming of the VLT 8000 AQUA.

The control panel is detachable and can — as an alternative — be installed up to 3m/10 ft away from the AFD, e.g. on the front panel, by means of a mounting kit option.

The functions of the control panel can be divided into five groups:

1. Display

2. Keys for changing display mode

3. Keys for changing program parameters

4. Indicator lamps

5. Keys for local operation.

All data are indicated by means of a 4-line alpha-numeric display, which, in normal operation, is able to show 4 operating data values and 3 operating condition values continuously. During programming, all the information required for quick, effective parameter

Setup of the AFD will be displayed. As a supplement to the display, there are three indicator lamps for voltage (ON), warning (WARNING) and alarm (ALARM),
