Safety and operating instructions for drive power converters

(as per: Low voltage guideline 73/23/EEC )

1. General

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

Unauthorised removal of covers, improper use, incorrect installation
or operation leads to the risk of serious personal injury or material
damage.

Further information can be found in this documentation.

All transportation, installation and initialisation and maintenance
work must be carried out by qualified personnel (comply with IEC
364, CENELEC HD 384, DIN VDE 0100, IEC 664 and 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 erection,
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 being installed in machines, the drive power converter cannot
be commissioned (i.e. implementation of the proper use) until it has
been ensured that the machine meets the provisions of the EC
directive 89/392/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 (89/336/EEC) is complied with.

The drive power converters meet the requirements of the low
voltage directive 73/23/EEC. The harmonised standards in prEN
50178/DIN VDE 0160, together with EN 60439-1/VDE 0660 Part
500 and EN 60146/VDE 0558 were applied for the drive power
converter.

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

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 that 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 4).

The electrical installation must be implemented as per 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 limit values specified in the EMC regulations is the
responsibility of the manufacturer of the system or machine.

6. Operation

Systems where drive power converters are installed must
be equipped, where necessary, with additional monitoring
and protective equipment as per the applicable safety
requirements, e.g. legislation concerning technical
equipment, accident prevention regulations, etc.
Modifications to the drive power converter using the
operating software are permitted.

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. Comply with the applicable
information signs located on the drive power converter.

All covers must be kept closed during operation.

7. Maintenance and repairs

The manufacturer documentation must be complied with.

These safety instructions must be kept in a safe place!

Supplementary Manual DeviceNet for NORDAC SK 200E

1 General information

Various technology options are available for Getriebebau Nord frequency inverters. General information
regarding these can be found in the relevant main manual of the frequency inverter series (e.g. Manual
BU0200 for the SK 200E frequency inverter series). Further information concerning special technology
options (e.g. the field bus module) is included in the relevant supplementary operating instructions.

This DeviceNet documentation contains supplementary descriptions concerning the DeviceNet options for
the SK 200E frequency inverter series.

The description of other optional modules (e.g. CANopen, Profibus DP) is dealt with in other supplementary
documentation.

In order to set up communication with DeviceNet, either an internal Customer Unit or an external
DeviceNet Technology Unit (according to the particular application) must be installed and connected.

The DeviceNet bus system

DeviceNet allows numerous different automation devices to exchange data with the frequency inverters.
PLC's, PC's, operating and monitoring devices can all communicate via a uniform bus in serial bit mode.
DeviceNet is primarily used for communication between sensor and actuator where system response needs
to be very fast. DeviceNet is primarily used where time critical, fast and complex communication between
the individual devices is essential. DeviceNet is a suitable alternative to expensive 24-volt parallel signal
transmission and transmission of measured values. This type of DeviceNet, which is optimised to speed, is
used for instance for operating frequency inverters on automation devices.

WARNING

THE DEVICES MUST BE EARTHED.

Safe operation of the devices presupposes that qualified personnel install and commission it in
compliance with the instructions provided in these operating instructions.

In particular, the general and regional mounting and safety regulations for work on high voltage
systems (e.g. VDE) must be complied with as must the regulations concerning professional use of
tools and the use of personal protection equipment.

Dangerous voltages can be present at the motor connection terminals of the frequency inverter
even when the inverter is switched off. Always use insulated screwdrivers on these terminal fields.

Ensure that the input voltage source is not live before setting up or changing connections to the
unit.

Make sure that the inverter and motor are specified for the correct supply voltage.

2.2.1 Cable glands

Both the SK 200E connection unit and the bus module provide extensive facilities for the connection of all the
required cables. The cables may enter the housing via cable glands and be connected to the terminal bar.
However, appropriate round plug connections (e.g.: M12 round plug connectors in M16 cable glands) may be
fitted in order to provide a plug-in solution.

The DeviceNet modules must be provided with one or two 24V DC (±20%, total current consumption 100mA)
control voltages. Wire end sleeves must be used for flexible cables.

Within the terminal box (unshielded cable section) the data cables (e.g. DeviceNet, system bus) must be
installed as short as possible and of equal length. Associated data cables (e.g.: Sys+ and Sys-) must be
twisted.

NOTE

In the customer unit, the DeviceNet is already installed with voltage isolation from the other
signal connections.

In case of EMC problems, voltage separation of the field bus supply, the digital inputs and
system bus interface and for the external technology unit also for the two additional digital
outputs should be provided.

NOTE

The cable shielding must be connected to the functional earthing1 (usually the
electrically conducting mounting plate) in order to prevent EMC interference in the
device.

In order to achieve this, for DeviceNet connections it is mandatory that the metallic metric
EMC screws are used for the connection of the DeviceNet shielding lead to the frequency
inverter or the housing of the technology unit. This ensures a wide area connection of the

functional earthing.

1

In systems, electrical equipment is usually connected to a functional earth. This serves as a means to dissipate leakage

and interference currents in order to ensure EMC characteristics and must therefore be implemented according to high
frequency technology aspects.

2.2.2.2 Control connections for SK TU4-DEV(-…)

The double spring-loaded terminal bar of the technology unit is colour coded, and therefore indicates the three
different potential levels.

A separate voltage source can be used to supply the DOs. However, by bridging the 24V o
of the terminals of the system bus level 24V

and GND it is possible to implement the supply of the DOs.

Connection of up to 4 sensors and 2 actuators is made via the terminal bar. Alternatively, the
