General safety and operating instructions for drive converters in conformity with the Low-Voltage Directive 79/23/EEC

1. General

In operation, drive converters, depending on their degree of protection, may have live, uninsulated, and possibly also moving or rotating parts, as well as hot surfaces.

In case of inadmissible removal of the required covers, or improper use, wrong installation or maloperation, there is the danger of serious personal injury and damage to property. For further information, see documentation.

All operations serving transport, installation and commissioning as well as maintenance are to be carried out by skilled technical personnel. (Observe IEC 364 or CELEC HD 384 or DIN VDE 0100 and IEC 664 or DIN/VDE 0110 and national accident prevention rules!)

For the purposes of these basic safety instructions, "skilled technical personnel" means persons who are familiar with the installation, mounting, commissioning and operation of the product and have the qualifications needed for the performance of their functions.

2. Intended use

Drive converters are components designed for inclusion in electrical installations or machinery.

In case of installation in machinery, commissioning of the drive converter (i.e. the starting of normal operation) is prohibited until the machinery has been proved to conform to the provisions of the directive 89/392/EEC (Machinery Safety Directive - MSD). Account is to be taken of EN 60204.

Commissioning (i.e. the starting of normal operation) is admissible only where conformity with the EMC directive (89/336/EEC) has been established.The drive converters meet the requirements of the low-voltage directive 73/23/EEC. They are subject to the harmonized standards of the series prEN 50178/DIN VDE 0160 in conjunction with EN 50439-1/VDE 0660, part 500, and EN 60146/VDE 0558.

The technical data as well as information concerning the supply conditions shall be taken from the rating plate and from the documentation and shall be strictly observed.

3. Transport, storage

The instructions for transport, storage and proper use shall be complied with.

The climatic conditions shall be in conformity with prEN 50178.

4. Installation

The installation and cooling of the appliances shall be in accordance with the specifications in the pertinent documentation.

The drive converters shall be protected against excessive strains. In particular, no components must be bent or isolating distances altered in the course of transportation or handling. No cantact shall be made with electronic components and contacts. Drive converters contain electrostatic sensitive components which are liable to damage through improper use. Electric components must not be mechanically damaged or destroyed (potential health risks).

5. Electrical connection

When working on live drive converters, the applicable national accident prevention rules (e.g. VB 4) must be complied with.

The electrical installation shall be carried out in accordance with the relevant requirements (e.g. cross sectional areas of conductors, fusing, PE connection). For further information, see documentation.

Instructions for the installation in accordance with the EMC requirements, like screening, earthing, location of filters and wiring, are contained in the drive converter documentation. They must always be complied with, also for drive converters bearing a CE marking. Observance of the limit values required by EMC law is the responsibility of the manufacturer of the installation or machine.

6. Operation

Installations, which include drive converters shall be equipped with additional control and protective devices in accordance with the relevant applicable safety requirements, e.g. Act respecting technical equipment, accident prevention rules, etc. Changes to the drive converters by means of the operating software are admissible.

After disconnection of the drive converter from the voltage supply, live applicance parts and power terminals must not be touched immediately because of possibly energized capacitors. In this respect, the corresponding signs and markings on the drive converter must be respected.

During operation, all covers and doors shall be kept closed.

7. Maintenance and servicing

The manufacturer’s documentation shall be followed.

KEEP SAFETY INSTRUCTIONS IN A SAFE PLACE!

Please observe the product-specific safety and operating instructions stated in these Operating Instructions.

2.4 Application as directed

The controllers of the 8600 series are electrical equipment intended for installation in control cabinets of high power plants.

The controllers are directed as components

•for the control of variable speed drives with three-phase AC motors.

•for the installation in control cabinets or control boxes.

•for the assembly together with other components to form a drive system.

•The controllers correspond to the Low-Voltage EMC directive.

•Drive systems with the 8600 controllers which are installed according to the requirements of the CE-typical drive systems correspond to the EC directive relating to EMC (see chapter 4.2.2).

The CE-typical drive with the 8600 controllers are suitable for

•the operation on public and non-public mains systems.

•the use in industrial areas as well and in residential and commercial premises.

•Because of the earth-potential reference of the RFI filter, the described CE-typical drive systems are not suitable for the connection to IT mains (mains without earth-reference potential).

•The controllers are not domestic appliances. They are intended as drive-system components for commercial use.

•The controllers themselves are not machines for the purpose of the EC directive relating to machinery.

2.5CE conformity

What is the purpose of the EC directives?

EC directives are issued by the European Council and are intended for the determination of common technical requirements (harmonization) and certification procedures within the European Community. At the moment, there are 21 EC directives of product ranges. The directives are or will be converted to national standards of the member states. A certification issued by one member state is valid automatically without any further approval in all other member states.

The texts of the directive are restricted to the essential requirements. Technical details are or will be determined by the European harmonized standards.

What does the CE mark imply?

After a verification, the conformity to the EC directives is certified by affixing a CE mark. Within the EC, there are no commercial barriers for a product with the CE mark. The enclosure of a conformity certification is not necessary according to most directives. Therefore, the customer cannot clearly see which of the 21 EC directives applies to a product and which harmonized standards are considered in the conformity verification.

Drive controllers with the CE mark themselves correspond exclusively to the Low-voltage Directive. For the compliance with the EMC directive only general recommendations have been issued so far. The CE conformity of the installed machine remains the responsibility of the user. For the installation of CE-typical drive systems, Lenze has already proved the CE conformity to the EMC directive.

What is the purpose of the EMC directive?

The EC directive relating to electromagnetic compatibility is effective for "equipment" which may either cause electromagnetic disturbances or be affected by such disturbances.

The aim is the limitation of the generation of electromagnetic disturbances so that the operation of radio and telecommunication systems and other equipment is possible. Furthermore, the units must be immune against electromagnetic disturbances to ensure an application as directed.

What is the objective of the Low-Voltage Directive?

The Low-Volgate Directive is effective for all electrical equipment for the use with a rated voltage between 50 V and 1000 V AC and between 57 V and 1500 V DC under normal ambient conditions.

The use of electrical equipment in e.g. explosive atmospheres and electrical parts in passenger and goods lifts are excepted.

The objective of the Low-voltage Directive is to ensure that only such electrical equipment which does not endanger the safety of man or animals is placed on the market. It should also be designed to conserve material assets.

4 Installation

4.1Mechanical installation

•These frequency inverters must only be used as built-in units.

•Install the inverter vertically with the terminal strips at the bottom.

•Allow a free space of 100 mm at the top and bottom. For the units 8612 ... 8615 this free space is also required at both sides.

Ensure unimpeded ventilation of cooling air.

•If the cooling air contains pollutants (dust, flakes, grease, aggressive gases), which may impair the inverter functions, suitable preventive measures must be taken, e.g. separate air duct, installation of a fiter, regular cleaning, etc.

•If the inverters are permanently subjected to vibration or shaking, shock absorbers may be necessary.

19

4.2 Electrical installation

• The drive controllers are equipped with electrostatically endangered components. The service and maintenance personnel must be electrostatically discharged before working at the units.

They can discharge by touching the PE fastening screw or another earthed metallic surface in the control cabinet.

•All control inputs and outputs of the inverter are mains-isolated. The mains isolation has a basic insulation. The control inputs and outputs must be integrated into another level of protection against direct contact.

Use insulated operating elements, connect the mechanical screwed joint of the set-value potentiometer to PE (assembly kit).

•Not used control inputs and outputs should be covered with plugs or protective covers which are supplied together with the unit.

•When using current-operated protective units:

−The controllers are equipped with an internal mains rectifier. As result, a DC fault current may prevent the tripping of the current-operated protective device after a short-circuit to frame.

Therefore, additional measures as protective multiple earthing or universal-current sensitive current-operated e.l.c.b. are required.

−When dimensioning the tripping current of current-operated e.l.c.b. it must be observed that there are capacitive leakage currents between cable screens and RFI filters during operation. These currents may result in false tripping of the current-operated e.l.c.b.

•The regulation about the min. cross-section of PE cables must be observed. The cross-section of the PE cable must be at least as large as the cross-section of the power connections.

•In the event of condensation, only connect the inverter to the mains when visible moisture has evaporated.

•Before switching on the inverter for the first time check whether there is an earth fault at the output side, if this is the case, clear the earth fault. Earth faults which occur during operation are detected, the inverter is then switched off and the message "OC1" is set.

•Frequent mains switching may overload the internal switch-on current limitation. For repeated mains connection, the inverter must not switched more often than every 3 minutes.

•Replace defective fuses only with the specified type and when the device is disconnected from the mains. The inverter remains live for up to 3 minutes after mains disconnection.

20

4.2.1 Motor protection

The units do not have a full motor protection.

For monitoring the motor temperature PTCs or thermal contacts can be used.

The connection possibilities are shown on page 28.

When using group drives, a motor protection relay is required for each motor.

When using motors which do not have a suitable insulation for inverter operation:

- Connect motor filters for protection (see page 43). Please contact your motor manufacturer.

Please note:

These frequency inverters generate an output frequency of up to 480 Hz when set correspondingly. The connection of a motor which is not suitable for this frequency may result in a hazardous overspeed.

4.2.2 Installation in compliance with EMC

•Lenze has built up typical drives with these controllers and has verified the conformity. In the following this system is called "CEtypical drive system".

If you observe the partially easy measures for the installation of CE-typical drive system, the inverter will not cause any EMC problems and you can be sure to comply with the EMC directive.

•The following configurations can now be selected by the user:

−The user himself can determine the system components and their integration into the drive system and is then held responsible for the conformity of the drive.

−The user can select the CE-typical drive system for which the manufacturer has already proved the conformity.

For deviating installations, e.g.

−use of unscreened cables,

−use of group filters instead of the assigned RFI filters,

−without mains choke

the conformity to the CE-EMC directives requires a check of the machine or system regarding the EMC limit values.

The user of the machine is responsible for the compliance with the EMC directive.

Installation of CE-typical drive systems

The electromagnetic compatibility of a machine depends on the method and accuracy of the installation. Special care must be taken of:

•filters,

•screens and

•grounding.

Filters

Only use suitable mains filters and mains chokes.

Mains filters reduce impermissible high-frequency disturbances to a permissible value.

Mains chokes reduce low-frequency disturbances, especially those caused by long motor cables.

Motor cables which are longer than 50 m must be protected additionally (motor filter or motor supply filter).

Screens

All cables from and to the inverter must be screened. Lenze system cables meet these requirements.

Ensure that the motor cable is laid separately from the other cables (signal cables and mains cables). Mains input and motor output must not be connected to one terminal strip.

Lay cables as close as possible to the reference potential. Dangling cables are like antennas.

Grounding

Ground all metall-conductive components (controllers, mains filters, mains chokes) using suitable cables from a central point (PE bar). Maintain the min. cross sections prescribed in the safety regulations. For EMC, the surface of the contact is important, not the cross section.

22

Installation

• Connect the inverter, mains filter, and mains choke to the grounded mounting plate. Zinc-coated mounting plates allow a permanent contact. If the mounting plates are painted, the paint must be removed in every case.

•When using several mounting plates they must be connected with as large surface as possible (e.g. using copper bands).

•Connect the screen of the motor cable to the screen connection of the inverter and to the mounting plate of a surface as large as possible. We recommend to use ground clamps on bare metal mounting surfaces to connect the screen to the mounting plate with as large surface as possible.

screened cable								mounting surfac

braid

ground clamp

•If contactors, motor protection switches or terminals are located in the motor cable, the screens of the connected cables must also be connected to the mounting plate with as large surface as possible.

•PE and the screen should be connected in the motor terminal box. Metal cable glands at the motor terminal box ensure a connection of the screen and the motor housing with as large a surface as possible.

•If the mains cable between mains filter and inverter is longer than 0.3 m, the cable must be screened. Connect the screen of the mains cable directly to the inverter module and to the mains filter and connect it to the mounting plate with as large as possible surface.

•When using a brake resistor, the screen of the brake resistor cable must be directly connected to the inverter and the brake resistor and it must be connected to the mounting plate with a surface as large as possible.

•The control cables must be screened. Digital control cables must be screened at both ends. Connect the screens of the control cables to the screen connections of the controllers leaving as little unscreened cable as possible.

•When using the inverters in residential areas an additional screening with a damping of ≥ 10 dB is required to limit the noise emission. This is usually achieved by installation into enclosed, grounded conrol cabinets or boxes made of metal.

Please note:

•If units, which do not comply with the noise immunity EN 50082- 2 required by the CE, are operated next to the inverters, an electromagnetic interference of these units is possible.

4.2.4 Switching on the motor side

Switching on the motor side is permissible for an emergency stop as well as during normal operation.

Please note that when switched with the controller enabled, this may cause the fault message OC1 (short circuit/earth fault). For long motor cables, the fault current on the interfering cable capacitances can become so large that the short circuit monitoring of the device is triggered. In these cases, a motor filter is necessary to reduce the fault currents (see page 43).
