Safety and operating instructions for drive power converters

(as per: Low Voltage Directive 2006/95/EEC )

1. General

During operation, drive power converters may, depending on their protection class, have live, bare, moving or rotating parts or hot surfaces.

Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of serious personal injury or material damage.

Further information can be found in this documentation.

All transportation, installation, initialisation and maintenance work must be carried out by qualified personnel (compliant with IEC 364, CENELEC HD 384, DIN VDE 0100, IEC 664 or DIN VDE 0110, and national accident prevention regulations).

For the purposes of these basic safety instructions, qualified personnel are persons who are familiar with the assembly, installation, commissioning and operation of this product and who have the relevant qualifications for their work.

2. Proper use in Europe

Drive power converters are components intended for installation in electrical systems or machines.

When installed in machines, the drive power converter cannot be commissioned (i.e. commencement of the proper use) until it has been ensured that the machine meets the provisions of the EC Directive 2006/42/EEC (machine directive); EN 60204 must also be complied with.

Commissioning (i.e. implementation of the proper use) is only permitted when the EMC directive (2004/108/EEC) is complied with.

CE-labelled drive power converters meet the requirements of the Low Voltage Directive 2006/95/EEC. The harmonised standards for drive power converters listed in the declaration of conformity are used.

Technical data and information for connection conditions can be found on the rating plate and in the documentation, and must be complied with.

The drive power converters may only be used for safety functions which are described and explicitly approved.

3. Transport, storage

Information regarding transport, storage and correct handling must be complied with.

4. Installation

The installation and cooling of the equipment must be implemented according to the regulations in the corresponding documentation.

The drive power converter must be protected against impermissible loads. Especially during transport and handling, components must not be deformed and/or insulation distances must not be changed. Touching of electronic components and contacts must be avoided.

Drive power converters have electrostatically sensitive components, which can be easily damaged by incorrect handling. Electrical components must not be mechanically damaged or destroyed (this may cause a health hazard!).

5. Electrical connection

When working on live drive power converters, the applicable national accident prevention regulations must be complied with (e.g. VBG A3, formerly VBG 4).

The electrical installation must be implemented according to the applicable regulations (e.g. cable cross-section, fuses, ground lead connections). Further instructions can be found in the documentation.

Information about EMC-compliant installation – such as shielding, earthing, location of filters and installation of cables can be found in the drive power converter documentation. These instructions must be complied with even with CE marked drive power converters. Compliance with the limiting values specified in the EMC regulations is the responsibility of the manufacturer of the system or machine.

6. Operation

Where necessary, systems where drive power converters are installed must be equipped with additional monitoring and protective equipment according to the applicable safety requirements, e.g. legislation concerning technical equipment, accident prevention regulations, etc.

The parameterisation and configuration of the drive power converter must be selected so that no hazards can occur.

All covers must be kept closed during operation.

7. Maintenance and repairs

After the drive power converter is disconnected from the power supply, live equipment components and power connections should not be touched immediately, because of possible charged capacitors. Observe the applicable information signs located on the drive power converter.

Further information can be found in this documentation.

These safety instructions must be kept in a safe place!

NORDAC SK 200E Manual

1 General information

These brief instructions for the SK 200E are based on the user manual for the frequency inverter - BU0200.

In addition to information concerning safety and use, this document also contains selected information on commissioning, as well as use of the frequency inverter in explosion hazard areas (ATEX Zone 22).

This manual is based on the device software V1.2 R0 (see P707) of the SK 200E. If the frequency inverter uses a different software version, this may cause differences.

A detailed description of the SK 200E and its options can be found in the user manual (BU0200). This and other documents can be downloaded free of charge from

www.nord.com.

1.1 Delivery

Check the equipment immediately after delivery/unpacking for transport damage such as deformation or

loose parts.

If there is any damage, contact the carrier immediately and carry out a thorough assessment.

Important! This also applies even if the packaging is undamaged.

6 BU 0240 GB

1.2 Safety and installation information

NORDAC SK 200E frequency inverters are devices for use in industrial high voltage systems and are

operated at voltages that could lead to severe injuries or death if they are touched.

• Installation and other work may only be carried out by qualified electricians and with the device disconnected. The operating instructions must always be available to these persons and must be strictly observed.

• Local regulations for the installation of electrical equipment and accident prevention must be complied with.

• The equipment continues to carry hazardous voltages for up to 5 minutes switched off at the mains.

• For single phase operation (115/230V) the mains impedance must be at least 100μH for each conductor. If this is not the case, a mains choke must be installed.

• For safe isolation from the mains, all poles of the supply cable to the frequency inverter must be able to be disconnected.

• Even during motor standstill (e.g. caused by a release block, blocked drive or output terminal short circuit), the line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages

. A motor standstill is not identical to

electrical isolation from the mains.

• Warning: with certain settings, the frequency inverter/motor can start up automatically

after the mains are switched on.

• The frequency inverter is only intended for permanent connection and may not be operated without effective earthing connections which comply with the local regulations for large leakage currents (> 3.5mA). VDE 0160 stipulates the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm

• Normal FI-circuit breakers are not suitable as the sole protection for three-phase

frequency inverters if the local regulations do not permit a possible DC proportion in the fault current. According to EN 50178 / VDE 0160, the FI circuit breaker must be an allcurrent sensitive FI circuit breaker (type B).

• In normal use, NORDAC SK 200E frequency inverters are maintenance free. The cooling surfaces must be regularly cleaned with compressed air if the ambient air is dusty.

1 General

CAUTION

The heat sink and all other metal components can heat up to temperatures above 70°C.

When mounting, sufficient distance from neighbouring components must be maintained. When working on the components, allow sufficient cooling time beforehand

Protection against accidental contact may need to be provided.

ATTENTION

DANGER TO LIFE

The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains. Inverter terminals, motor cables and motor terminals may carry voltage!

Touching open or free terminals, cables and equipment components can lead to severe injury or death!

Work may only be carried out by qualified specialist electricians and with the electrical supply to the equipment disconnected!

1.3 Wiring guidelines

The frequency inverter has been developed for use in an industrial environment. In this environment, high levels of electromagnetic interference can influence the frequency inverter. In general, correct installation ensures safe and problem-free operation. To meet the limiting values of the EMC directives, the following instructions should be complied with.

(1) Ensure that all equipment in the control cabinet is securely earthed using short earthing cables which

have large cross-sections and are connected to a common earthing point or earthing bar. It is especially important that all control devices connected to the frequency inverters (e.g. an automation device) are connected to the same earthing point as the inverter itself, using a short cable with large cross-section. Flat conductors (e.g. metal clamps) are preferable, as they have a lower impedance at high frequencies.

(2) The bonding cable of the motor controlled by the frequency inverter should be connected directly to the

earthing terminal of the associated frequency inverter. The presence of a central earthing bar in the control cabinet and the grouping together of all bonding conductors to this bar normally ensures safe operation.

(3) Where possible, shielded cables should be used for control loops. The shielding at the cable end

should be carefully sealed and it must be ensured that the wires are not laid over longer distances without shielding.

The shields of analog setpoint cables should only be earthed on one side on the frequency inverter.

(4) The control cables should be installed as far as possible from power cables, using separate cable

ducts, etc. Where cables cross, an angle of 90° should be ensured as far as possible.

(5) Ensure that the contactors and brake chokes in the cabinet are interference protected, either by RC

circuits in the case of AC contactors, or by “free-wheeling” diodes for DC contactors, for which the interference protectors must be positioned on the contactor coils. Varistors for over-voltage

limitation are also effective. This interference suppression is particularly important when the contactors are controlled by the relay in the frequency inverter.

(6) Use screened or armoured cable for the load connections (motor cable) and earth the

screening/armour at both ends, if possible to the frequency inverter bonding.

In addition, an EMC-compliant cabling must be ensured.

The safety regulations must be complied with under all circumstances when installing the

frequency inverter!

1 General

NOTE

The control cables, line cables and motor cables must be laid separately. In no case should they be laid in the same protective pipes/installation ducts.

The test for high voltage insulations must not be used on cables which are connected to the frequency inverter.

ATTENTION

With the use of a ParameterBox SK PAR-3H this must never be simultaneously connected to the frequency inverter and the PC, as potential shifts may cause damage, especially to the PC. (See also Manual BU0040)

2 Assembly and installation

2.1 Installation and assembly

NORDAC SK 200E frequency inverters are available in various sizes depending on their output. Connection of the SK 200E to the motor or the wall-mounting unit is made by means of the a suitable size of connection unit SK T14-… The frequency inverter is mounted by means of integrated plug contacts.

The devices require adequate ventilation to protect against overheating.

Motor-mounted version Mounting must therefore always be carried out as shown in the illustration. For permanently low motor speeds and self-ventilated motors, a reduction in power similar to the wall-mounted version must be taken into account.

: Here, the ventilation of the motor is integrated into the cooling concept of the FI.

Wall-mounted version

: In continuous operation (S1), mounting away from the motor causes a reduction in the power of the FI by one power level. This means that relative to the motor, the FU must be selected one power level larger.

NOTE

For further details of the power reduction and the possible ambient temperatures, please refer to the technical data in BU0200
