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 98/37/EEC (Machine 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.
The drive power converters meet the requirements of the Low
Voltage Directive 2006/95/EEC. The harmonized standards stated in
the Declaration of Conformity are used for the drive power
converters.
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 the safety
functions which are described and for which they have been
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 converters 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 connections
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 information is contained
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 relevant
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 Concerning this document
BU 0200 GB 5
Intended use of the frequency inverter
Compliance with the operating instructions is necessary for fault-free operation and the
acceptance of possible warranty claims. These operating instructions must be read before
working with the device!
These operating instructions contain important information about servicing. They must
therefore be kept close to the device.
SK 200E frequency inverters are devices for industrial and commercial plants for operating
three-phase asynchronous motors with squirrel-cage rotors. These motors must be suitable
for operation with frequency inverters. Other loads must not be connected to the devices.
SK 200E frequency inverters are devices for fixed installation on motors or in systems in the
vicinity of the motors to be operated. All details regarding technical data and
permissible conditions at the installation site must be complied with.
Commissioning (commencement of the intended use) is not permitted until it has been ensured
that the machine complies with the EMC Directive 2004/108/EEC and that the conformity of

1 General information
The NORDAC SK 200E is based on the tried and tested NORD platform. These devices feature a compact
design with optimum control characteristics.
These devices are provided with sensorless vector current control which in combination with asynchronous
three-phase motor types constantly ensures an optimised voltage-to-frequency ratio. This has the following
significance for the drive: Peak start-up and overload torques at constant speed.
This series of devices can be adapted to individual requirements by means of extension modules.
Due to the numerous setting options, these inverters are capable of operating all three-phase motors. The
power range is from 0.25kW to 7.5kW with an integrated mains filter.
This manual is based on the device software V1.2 R0 (see P707) of the SK 200E. If the frequency inverter
used has a different version, this may lead to some differences. If necessary, you can download the current
manual from the Internet (http://www.nord.com/).
For the SK 215E/225E/235E there are additional descriptions for functional safety
(BU 0230), the integrated AS interface (BU 0200, Section 5.4) and the positioning system (BU 0210). These
contain all the necessary additional information for start-up.
If a bus system is used for communication, a corresponding description (e.g. BU 0220 für PROFIBUS DP) is
provided, or this can be downloaded from the Internet (http://www.nord.com/).
Typically, this series of devices is installed directly on a three-phase asynchronous motor. Alternatively,
there are optional accessories for mounting the devices in the vicinity of the motor, e.g. on a wall or the
frame of a machine.
In the simplest configuration, even without an EEPROM, there is the possibility of setting all important
parameters via two potentiometers and eight DIP switches. LEDs are provided for the diagnosis of the
operating status. The use of a control module is therefore not absolutely necessary.
In order to gain access to all parameters, the internal RS232 PC interface (RJ12) can be used, or an
optional SimpleBox or ParameterBox may be used. In this case, the parameter settings which have been
changed by the operator are stored in the plug-in EEPROM. The EEPROM must then always remain
plugged in during operation.
ATTENTION
For changes to the frequency inverter software V 1.2 R0, the structure of individual
parameters has been changed for technical reasons.
(E.g.: up to version V 1.1 R2, (P417) was a simple parameter. As of version V 1.2. R0 this has been
divided into two arrays ((P417) [-01] and [-02]))
When plugging an EEPROM from a frequency inverter with an earlier software version into
a frequency inverter with a software version higher than V 1.2, the stored data is
automatically adapted to the new format. the new parameters are saved in the default
settings. Correct functioning is therefore ensured.
However, it is not permissible to plug an EEPROM with a software version higher
than V 1.2 into a frequency inverter with a lower software version, as this may lead to
a complete loss of data.

1.4 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 from mains. 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 after being
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 an electronic 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 mm2.
•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 all-
current 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.
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 frequency inverter can carry voltages for up to 5 minutes after being switched off at the

1.7 Version with protection class IP55 / IP66
NORDAC SK 200E frequency inverters and the additional modules are available in all sizes and in the
protection classes IP55 (standard) or IP66 (optional).
Protection class IP66 must always be stated when ordering!
There are no restrictions or differences to the scope of functions in either protection class. In order to
differentiate the protection classes, modules with protection class IP66 are given an extra “-C” (coated Æ
coated PCBs) in their type designation. e.g. SK 205E-750-340-A-C
IP55 version:
The IP55 version of the SK 200E is the standard version. Both versions (motor-mounted, mounted on the
motor or wall-mounted on a wall bracket) are available. In addition, all adapter units, technology units and
customer units are available for this version.
IP66 version:
In contrast to the IP55 version the IP66 version is a modified option. Both variants (motor-integrated, close
to motor) are also available. The modules available for the IP66 version (adapter units, technology units and
customer units) have the same functionalities as the corresponding modules for the IP55 version.
NOTE
The modules for the IP66 design are identified by an additional "-C" and are modified
according to the following special measures listed below.
Special measures:
Impregnated PCBs, painted housing
Diaphragm valve for pressure compensation on temperature changes.
Low pressure test
ÆA free M12 screw connection is required for low pressure testing. After successful testing, a
diaphragm valve is inserted here. This screw connection is therefore no longer available for
a cable gland.
If the frequency inverter is to be retro-fitted, i.e. the drive unit (inverter mounted on the motor) is not
completely obtained from NORD, the membrane valve is supplied in the bag supplied with the frequency
inverter. The valve must be correctly fitted on site by the plant constructor (Note: the valve must be mounted
as high as possible, in order to avoid contact with standing moisture (e.g.: standing moisture due to
condensation).
NOTE
For all versions, care must be taken that the cable and the cable gland are carefully
matched. This is the only way to ensure permanent compliance with the required protection
class.
