Safety and operating instructions
for drive power converters
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 commissioning and maintenance work
must be carried out by qualified personnel (compliant with IEC 364
or. CENELEC HD 384 or DIN VDE 0100 and 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 must not 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 (Machinery Directive); EN 60204 must also
be complied with.
Commissioning (i.e. implementation of the proper use) is only
permitted if the EMC directive (2004/108/EEC) is complied with.
Drive power converters with a CE label meet the requirements of the
Low Voltage Directive 2006/95/EEC. The stated harmonized
standards for drive current inverters are used in the declaration of
conformity.
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.
(as per: Low Voltage Directive 2006/95/EEC )
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. BGV A3, formerly VBG 4).
The electrical installation must be implemented as per the
applicable regulations (e.g. cable cross-section, fuses, earth
lead connections) . Further instructions can be found in the
documentation.
Information regarding 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 in which 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.
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!

2.1 NORDAC SK 500E
By the use of various modules for display, control and parameterisation, the NORDAC SK 5xxE can be easily
adapted to various requirements.
Alphanumerical display and operating modules can be used for simple commissioning. For more complex
tasks, various connections to a PC or an automation system can be selected.
The technology unit (Technology Unit, SK TU3-…) is connected externally to the front of the frequency inverter
and is therefore easy to access and replace at any time.
In the delivery condition, without the technology unit, 2 LEDs (green/red) are visible externally. These signal
the actual device status.
The green LED indicates that the mains voltage is present and operational, while a flashing code that
increases in speed shows the degree of overload at the frequency inverter output.
The red LED signals actual error by flashing with a frequency which corresponds to the number code of the
error (Manual BU 0500 Section 6).

2.1.1 DeviceNet module SK TU3-DEV
This DeviceNet module can be used for all types of SK 500E devices. It occupies the technology slot which
can then no longer be used for control and display modules. Alternatively, the SimpleBox SK CSX-0 can be
plugged on to the DeviceNet module and connected via the RS232/485 interface with the frequency inverter.
The DeviceNet module must be provided with an external 24V power supply
therefore be identified by the master system even without a voltage supply to the frequency inverter. The data
required for this purpose are set using a rotary coding switch. This Bus data is read in when the 24V is applied
from the frequency inverter.
Supply voltage:
The supply voltage is 24V DC ±25% (pin 1 = V-, pin 5 = V+ (from left to right)). The connection is made via the
5-pin open-style plug connector. (See illustration below)
Setting the node address: (See Section.
5.4)
The node address (0...63) can be set with the rotary switches NA x 1 and NA x 10:
Example: Node address = 50 dec = NAx 1 = 0, NAx 10 = 5
If the node address is set to a value greater than 63, the value from the parameter (P515[-01]) of the frequency
inverter is used as the node address.
Setting the baud rate: (See Section
5.4)
The baud rate can be set using the rotary switch DR (125kBit/s...500kBit/s). If a value in the PGM range is set,
the value from parameter (P514) of the frequency inverter is used as the baud rate.
Note: The settings made using the rotary coding switch are not transferred to the frequency inverter or saved.

2.2 NORDAC SK 700E
With the combination of modules for display, technology units and modules with digital and analog inputs and
interfaces, customer interfaces or special extensions, the NORDAC SK 700E can easily be extended tot
cater for the requirements of a wide range of different applications.
WARNING
Technology units (TU) are modules which can be inserted from
above for display, parameterisation and control of the inverter.
Customer interfaces (Customer Units) are modules which are
inserted into the upper slot inside the inverter. They are used fo
control and communication using digital/analog signals or bus
interfaces.
Special extensions (EXtension Units) are inserted into the lower slot of
the inverter. Such an extension unit is required if the speed is to be
controlled or positioned by an incremental (absolute) encoder.
Modules must not be inserted or removed unless the device is free of voltage. The slots may
only be used for the intended modules. The slots are coded to prevent them being mixed up.
Installation of a technology unit separate from the frequency inverter is not possible. It must be
connected directly to the frequency inverter.

2.2.1 DeviceNet module SK TU1-DEV
This DeviceNet module can be used for all types of SK 700E devices. It occupies the technology slot which
can then no longer be used for control and display modules. Alternatively, a hand-held parameter box SK
PAR-xH (with adapter cable) can be connected to the frequency inverter via an optional RS232/RS485
interface.
The DeviceNet module must be provided with an external 24 V power supply
therefore be identified by the master system even without a voltage supply to the frequency inverter. The data
required for this purpose are set using a rotary coding switch. This Bus data is read in when the 24V is applied
from the frequency inverter.
Supply voltage:
The supply voltage is 24V DC ±25% (pin 1 = V-, pin 5 = V+ (from left to right)). The connection is made via the
5-pin open-style plug connector. (See illustration below)
Setting the node address: (See Section.
5.4 )
The node address (0...63) can be set with the rotary switches NA x 1 and NA x 10:
Example: Node address = 50 dec = NAx 1 = 0, NAx 10 = 5
If the node address is set to a value greater than 63, the value from the parameter (P515) of the frequency
inverter is used as the node address.
Setting the baud rate: (See Section.
