Safety and operating instructions
for motor starters
1. General
During operation, motor starters may, depending on their protection
class, have live, bare, moving or rotating parts or hot surfaces.
Unauthorised removal of covers, improper use, incorrect inst allation
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 ass embly, installation,
commissioning and operation of this product and who have the relevant qualifications for their work.
2. Proper use in Europe
Motor starters are components intended for ins tallation in electrical
systems or machines.
When installed in machines, the drive power convert er must not be
commissioned (i.e. commencement of the proper use) until it has
been ensured that the machine m eets the provisions of the EC Directive 2006/42/EEC (Machinery Directive); EN 60204 must also be
complied with.
Commissioning (i.e. implementation of t he proper use) is only permitted if the EMC directive (2004/108/EEC) is complied with.
CE-labelled m otor starters 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 motor starters 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 motor starter 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.
Motor starters have electrostatically sensit ive 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 components, the applicable national accident prevention regulations must be complied with
(e.g. BGV A3, formerly VBG 4).
The electrical installation must be im plement ed according t o
the applicable regulations (e.g. cable cross-section, fuses,
earth lead connections). Further instruct i ons 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 docum entation. These instructions must be complied with even with CE
marked motor starters. Compliance with the limiti ng values
specified in the EMC regulations is the responsibility of t he
manufacturer of the system or machine.
6. Operation
Systems in which motor starters are installed must be
equipped, where necessary, with addi tional 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 m otor starter
must be selected so that no hazards can occur.
All covers must be kept closed during operation.
7. Maintenance and repairs
After the motor starter is disconnect ed 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!

SK 105E…175E Motor Starter Manual
1 General information
The SK 1x5E series is based on the tried and tested NORD platform. These devices feature a compact
design with optimum characteristics.
Due to dual phase control, not onl y a pure motor start, but also a soft start is possible. T he phase control
process was selected s o that the res ulting harm onic torques are k ept as low as possible. A c omprehensiv e
spectrum of monitoring functions rounds off the range.
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. The device is equipped with an integrated mains filter.
This manual is based on the device sof tware V1.0 R0 (see P707) of the motor s tarter. If the motor star ter
uses a different software version, this may cause differences. If necessary, the latest manual should be
downloaded from the Internet (www.nord.com
For the various versions of the device series SK 105E…SK 175E there are differences in functions, the
integrated AS interface or the integrated PROFIBUS interface.
Typically, this series of devices is installed directly on a three-phase asynchronous motor. Alternatively,
optional accessories are available for m ounting the devices close to the motor, e.g. on the wall or on a
machine frame.
In the simplest config uration, ev en without a PC or contr ol box, all of the mos t important par ameter s can be
set using up to four potent iometers and the four DIP switches . LEDs are pr ovided for the diagnostics 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 Param eterBox may be used. I n this case, t he parameter settings which are changed
by the user are saved in the flash memory of the device.
A permanent connection via the RS 232 interface is not intended for normal operation.

2.3 Wiring guidelines
The motor starters have be en developed for use in an industr ial environm ent. In this environm ent, high le vels of electromagnetic interference can inf luence the motor starter. In genera l, correct installation ensures
safe and problem-f ree operation. To meet the limiting values of the EMC directives, the following i nstructions should be complied with.
(1) Ens ure that a ll equipm ent in th e control c abinet or field is s ecurel y earthed us ing shor t earthing c ables
which have large cross-sections a nd are connected to a comm on earthing point or earthing rail. It is
especially important th at all control dev ices connected to the motor star ter (e.g. an automat ion device)
are connected to the same earthing point as the motor starter itself, using a short cable with large
cross-section. Flat conductor s (e.g. metal clam ps) are preferable, as they have a lower impedance at
high frequencies.
(2) The bonding cable of the motor controlled by the motor starter should be connected directly to the
earthing terminal of the as sociated motor star ter. The presence of a c entral earthing bar in the contr ol
cabinet and the grouping together of all bonding conductors to this bar normally ensures safe
operation. (See also Section 7.3 / 7.4(EMC))
(3) W here possible, shielded cables should be used for control circuits. 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.
(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) Ens ure that the contactors and brake chok es in the cabinet are interference protected , either by RC
circuits in the case of AC contactors, or by “free-wheeling” diodes for DC contactors, whereby the
interference protectors must be positioned on the contactor coils. Varistors for over-voltage
limitation are also effective.
In addition, an EMC-compliant cabling must be ensured. (See also Section 7.3 / 7.4 (EMC)).
The safety regulations must be complied with under all circumstances
when installing the motor starter!
