FUNCTIONAL SAFETY-COMPLIANT USE

The VLT® Plus Panel is a product in accordance with the Low Voltage Directive 2006/95/EG, but does not provide safety-related control functionality in accordance with Machine Safety Directive 2006/42/EG. CE declaration is therefore related to EMC (2004/108/EG) and LV Directive. Failure to take the necessary safety-related control measures can result in death or serious injury.

•

The panel operator has to ensure the proper use of the product, even when Safe Torque O (STO) functionality is used, for example for ATEX-conform motor thermal protection. In this case, the safety function is part of the approved motor thermal protection, using the function as appropriate energy cut-o.

•

Any other use of the safety functions is in sole responsibility of the end user, including certi- cation, documentation, and so on.

•

Customized variants can dier and are not subject to the Panel congurator products description.

NOTICE

For VLT® AutomationDrive FC 302, NO (Normal overload) values are used for the design. Due to the 80% design rule of EN 61439-2, design is adjusted for the HO (High overload) use. Details are provided per power rating in the relevant documents.

The VLT® Plus Panel is designed to provide high shaft performance on electrical motors along with extra features (see chapter 1.4.2 Features).

Depending on conguration, the VLT® Plus Panel can be used in stand-alone applications or form part of a larger appliance or installation. It is intended to be used solely for the application it was

tailored to (see documentation provided with the VLT

Plus Panel). The intended use of the frequency converter, as described in the frequency converter documentation applies, and must be observed.

The VLT® Plus Panel is allowed for use in residential, industrial, and commercial environments in accordance with local laws, standards, and emission limits as described

Optimised duct cooling

A dedicated option allows optimised installation of IP00 rated frequency converters in Rittal TS8 enclosures. Therefore, the fan of the frequency converter is used for forced air cooling of the backchannel. The exhaust air on the top of the enclosure can be ducted outside a facility. So, the heat losses from the backchannel are not dissipated within the control room. Hence, the airconditioning requirements of the facility are not impacted.

Introduction

VLT® Plus Panel

See Installation of Duct Cooling Kit in Rittal Enclosures, for further information.

The remaining heat losses are handled via fans and lter

combinations in the VLT® Plus Panel front doors.

Door fan

One or more door fans remove the heat losses not contained in the frequency converter backchannel and any additional losses generated from other components installed inside the enclosure. The total required air ow is calculated with a dedicated software tool and the required air ow is shown in the panel documentation.

The frequency converter fan runs for the following reasons:

•

AMA.

•

DC hold.

•

Pre-mag.

•

DC brake.

•

60% of nominal current is exceeded.

•

Specic heat sink temperature exceeded (power size dependent).

•

Specic power card ambient temperature exceeded (power size dependent).

•

Specic control card ambient temperature exceeded.

Once the frequency converter fan is started, it runs for minimum 10 minutes.

The door fans run, whenever the thermostat inside the panel reaches the adjusted limit. Once the o-setpoint is reached, it switches the fans o. The duration of the ontime varies and depends on the load and local conditions, as well as on the pollution of the air lters.

Cabinet light with power outlet

A light mounted on the cabinet interior increases visibility during servicing and maintenance. The light housing includes a power outlet (230 V, 50 Hz, 2.5 A, CE/ENEC) for temporarily supplying power to tools or other devices.

Accessibility of the installation site.

•

How to cool the unit.

•

Position of the frequency converter.

•

Cable routing.

•

Ensure that the power source supplies the correct voltage and necessary current.

•

Ensure that all electrical conditions match with

the VLT® Plus Panel design, such as, but not limited to, short circuit capability, short circuit withstand capability, and voltage.

•

Ensure that the motor current rating is within the maximum current from the frequency converter.

•

If the VLT® Plus Panel is without built-in fuses, ensure that the external fuses are rated correctly.

Wire access

Ensure that proper cable access is present including necessary bending allowance. Cables must be

xed to remove force and weight from the cable termination points. This can be done while using the C rails provided in the plinth, applying cable clamps (not part of the delivery). For EMC reasons, cable shields have to be connected to the construction, for example with EMC cable glands (not provided).

NOTICE

All cable lugs/shoes must mount within the width of the terminal bus bar.

Space

Ensure proper space above and below the VLT® Plus Panel to allow airow and cable access. In addition, consider space in front of the unit to enable opening of the door of the panel.

Terminal locations

Terminal locations can be found in the detail documentation, as provided per unit. The terminal locations vary because of multiple options on the infeed options, power rating, and so on. Data on maximum torque for the termination points are provided in the panel documentation.

NOTICE

All cable and terminal dimensions can be found in the documentation package supplied with the unit. The power cables are heavy and hard to bend. Consider the optimum position of the frequency converter for ensuring easy installation of the cables.

3.2 Cooling

NOTICE

The unit sucks the cooling air in from the bottom. To allow cooling air intake from the bottom:

•

Place the unit on a double-oor (standard installation).

•

For non double-oor environments: Make sure to adapt for instance the plinth to allow cooling air intake in from the bottom.

The VLT® Plus Panel dissipates power in the form of heat. Cooling can be obtained in dierent ways, by using the cooling ducts in the bottom and the top of the unit. See Installation of Duct Cooling Kit in Rittal Enclosures, for further information.

The following recommendations are necessary for eective cooling of the units:

•

Mount the unit allowing for unhindered cooling airow through the cooling ns.

•

Provide 225.0 mm (8.86 in) minimum clearance above the unit for airow.

•

Provide clearance for airow. Do not cover all air inlets and air outlets.

For airow path, see Illustration 1.1, Illustration 1.2, and Illustration 1.3.

NOTICE

Improper cooling can lead to derating and result in reduced performance or failure of the application.

Mechanical Installation Installation Guide

3 3

3.3 Derating

Consider derating when any of the following conditions are present.

•

Operating above 1000 m (low air pressure)

•

High ambient temperature

•

Insucient cooling

•

High switching frequency

•

Low-speed operation

•

Long motor cables

•

Cables with a large cross-section

3.4 Operating Environment

For specications regarding ambient conditions, see chapter 5 Specications.

NOTICE

CONDENSATION

Moisture can condense on the electronic components and cause short circuits. Avoid installation in areas subject to frost. Install an enclosure heater when the

VLT® Plus Panel is colder than the ambient air. Operating in stand-by mode reduces the risk of condensation as long as the power dissipation keeps the circuitry free of moisture.

NOTICE

EXTREME AMBIENT CONDITIONS

Extremely hot or cold temperatures compromise unit performance and longevity.

•

Do not operate in environments where the ambient temperature exceeds 30 °C (86 °F).

•

Extra air conditioning of the enclosure or installation site can be required.

3.4.1 Gases

Aggressive gases, such as hydrogen sulphide, chlorine, or ammonia can damage the electrical and mechanical components.

3.4.2 Dust

When installing the VLT® Plus Panel in dusty environments, pay attention to the following:

Periodic maintenance

When dust accumulates on electronic components, it acts as a layer of insulation. This layer reduces the cooling capacity of the components, and the components become warmer. The hotter environment decreases the life of the electronic components.

Keep the heat sink and fans free from dust build-up.

Cooling fans

Fans provide airow to cool the VLT® Plus Panel. When fans are exposed to dusty environments, the dust can damage the fan bearings and cause premature fan failure.

3.4.3 Potentially Explosive Atmospheres

WARNING

EXPLOSIVE ATMOSPHERE!

Do not install a VLT® Plus Panel in a potentially explosive atmosphere. Install the unit in a cabinet outside of this area. Failure to follow this guideline increases risk of death or serious injury.

Systems operated in potentially explosive atmospheres must full special conditions. EU Directive 94/9/EC (ATEX

95) classies the operation of electronic devices in potentially explosive atmospheres.

•

Class d species that if a spark occurs, it is contained in a protected area.

•

Class e prohibits any occurrence of a spark.

Motors with class d protection

Does not require approval. Special wiring and containment are required.

Motors with class e protection

When combined with an ATEX approved PTC monitoring

device like the VLT® PTC Thermistor Card MCB 112, installation does not need an individual approval from an approbated organisation.

Motors with class d/e protection

The motor itself has an e ignition protection class, while the motor cabling and connection environment comply with the d classication. Use a sine-wave lter at the active front-end drive output to attenuate the high peak voltage.

4.1 Safety Instructions

See chapter 2 Safety for general safety instructions.

WARNING

INDUCED VOLTAGE!

Induced voltage from output motor cables from dierent frequency converters that are run together can charge equipment capacitors even with the equipment turned o and locked out. Failure to run output motor cables separately or use screened cables could result in death or serious injury.

•

Run output motor cables separately, or

•

Use screened cables.

•

Simultaneously lock out all the frequency converters.

WARNING

SHOCK HAZARD

The frequency converter can cause a DC current in the PE conductor and hence result in death or serious injury.

•

When a residual current-operated protective device (RCD) is used for protection against electrical shock, only an RCD of Type B is permitted on the supply side.

Failure to follow the recommendation means that the RCD cannot provide the intended protection.

Overcurrent protection

•

Extra protective equipment such as short-circuit protection or motor thermal protection between frequency converter and motor is required for applications with multiple motors.

•

Input fusing is required to provide short-circuit and overcurrent protection. If fuses are not factory-supplied, the installer must provide them. See maximum fuse ratings in chapter 4.4 Fuses.

Wire type and ratings

•

All wiring must comply with local and national regulations regarding cross-section and ambient temperature requirements.

•

Power connection wire recommendation: Minimum 75 °C rated copper wire.

See chapter 5 Specications for recommended wire sizes and types.

4.1.1 General Notes on Cabling and Fusing

NOTICE

All cabling must comply with national and local regulations on cable cross-sections, cable types, and ambient temperature.

For protection of the frequency converter, use the recommended fuses or install a unit with built-in fuses. For recommended fuses, see chapter 4.4 Fuses. Always ensure that proper fusing is made according to local regulation.

The mains connection is tted to the rst switch gear in the mains circuit if this is included.

4.2 EMC Compliant Installation

Perform the following steps to support EMC-compliant installation:

NOTICE

TWISTED SCREEN ENDS (PIGTAILS)

Twisted screen ends increase the screen impedance at higher frequencies, which reduces the screen eect and increases the leakage current. Avoid twisted screen ends.

•

Connect the screen to the enclosure at both ends for use with:

- Relays.

- Control cables.

- A signal interface.

- Fieldbus.

- Brake.

If the ground path has high impedance or is noisy or is carrying current, break the screen connection on 1 end to avoid ground current loops.

•

Use a metal mounting plate to convey the currents back to the unit. Ensure good electrical contact from the mounting plate through the mounting screws to the frequency converter chassis.

•

Use screened cables for motor output cables. An alternative is unscreened motor cables within metal conduit.

Electrical Installation Installation Guide

4 4

NOTICE

INSTALLATION AT HIGH ALTITUDE

There is a risk for overvoltage. Isolation between components and critical parts could be insucient, and may not comply with PELV requirements. Reduce the risk for overvoltage by using external protective devices or galvanic isolation. For installations above 1000 m (3281 ft) altitude, contact Danfoss regarding PELV compliance.

NOTICE

PELV COMPLIANCE

Prevent electric shock by using protective extra low voltage (PELV) electrical supply and complying with local and national PELV regulations.

4.3 Grounding

WARNING

LEAKAGE CURRENT HAZARD!

Leakage currents exceed 3.5 mA. Failure to ground the frequency converter properly could result in death or serious injury.

•

Ensure the correct grounding of the equipment by a certied electrical installer.

For electrical safety

•

Ground the frequency converter in accordance with applicable standards and directives.

•

Use a dedicated ground wire for input power, motor power, and control wiring.

•

Do not ground one frequency converter to another in a daisy chain fashion.

•

Keep the ground wire connections as short as possible.

•

Follow motor manufacturer wiring requirements.

•

Minimum cable cross-section: 10 mm2.

•

Terminate 2 rated ground wires separately, if applicable in accordance with national and local codes.

For EMC-compliant installation

•

Establish electrical contact between the cable screen and the frequency converter enclosure by using metal cable glands or by using the clamps provided on the equipment. See Illustration 4.1.

•

Reduce burst transient by using high-strand wire.

•

Do not use pigtails.

•

Use serrated washers or split washers with enclosure assembly screws. Anodized aluminum enclosures provide inadequate ground bonding when plain washers are used.

•

To obtain a low impedance contact, scrape painted surfaces down to the bare metal.

NOTICE

POTENTIAL EQUALISATION

Risk of burst transient, when the ground potential between the frequency converter and the control system is dierent. Install equalizing cables between the system components. Recommended cable cross-section: 16 mm

(4 AWG) or larger.

4.4.1 Motor Insulation

For motor cable lengths ≤ the maximum cable length listed in chapter 5

Specications, the recommended motor insulation ratings are in Table 4.1. The peak voltage can be up to twice the DC-link voltage, 2.8 times the mains voltage, due to transmission line eects in the motor cable. If a motor has a lower insulation rating, use a dU/dt or sine wave lter.

Nominal mains voltage Motor insulation

UN ≤420 V

Standard ULL = 1300 V

420 V <UN ≤500 V Reinforced ULL = 1600 V

500 V <UN ≤600 V Reinforced ULL = 1800 V

600 V <UN ≤690 V Reinforced ULL = 2000 V

Table 4.1 Motor Insulation at Various Nominal Mains Voltages

4.4.2 Motor Bearing Currents

All motors installed with FC 302 90 kW or higher power frequency converters should have NDE (non-drive end) insulated bearings installed to eliminate circulating bearing currents. To minimize DE (drive end) bearing and shaft currents, proper grounding of the frequency converter, motor, driven machine, and motor to the driven machine is required.

Standard mitigation strategies:

1. Use an insulated bearing.

2. Apply rigorous installation procedures.

2a Ensure that the motor and load motor

are aligned.

2b Strictly follow the EMC installation

guideline.

2c Reinforce the PE so the high frequency

impedance is lower in the PE than the

input power leads.

2d Provide a good high frequency

connection between the motor and the

frequency converter. Achieve that for

example by using a screened cable

which has a 360° connection in the

motor and the frequency converter.

2e Make sure that the impedance from

frequency converter to building ground

is lower than the grounding impedance

of the machine. This can be dicult for

pumps.

2f Make a direct ground connection

between the motor and load motor.

3. Lower the IGBT switching frequency.

Modify the inverter waveform, 60° AVM versus SFAVM.

5. Install a shaft grounding system or use an isolating coupling.

6. Apply conductive lubrication.

7. Use minimum speed settings if possible.

8. Try to ensure that the line voltage is balanced to ground. This can be dicult for IT, TT, TN-CS or grounded leg systems.

9. Use a dU/dt or sinus lter.

4.4.3 Control Cable Routing

Tie down all control wires to the designated control cable routing. To ensure optimum electrical immunity, connect the screens properly.

Fieldbus connection

Connections are made to the relevant options on the control card. For details, see the relevant eldbus instruction. Place the cable in the provided path inside the frequency converter and tie it down with other control wires.
