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!

For Zone 22 the cable glands must at least comply with protec tion class IP 55. Unused open ings must be
closed with blank screw caps suitable for ATEX Zone 22 3D (minimum protection class IP 55).
The motors are protected against overheating by means of the motor starter. This is carried out by the
evaluation of the motor PTC in the motor starter. In order to ensure this function, the PTC must be
connected to the intende d input (Terminal 38/39 control term inal plug connector) . In addition, care m ust be
taken that the nominal current of the motor is adjusted accordingly.

NOTE
It must be noted that the DIP switch setting (S 1) has prior ity ov er the par ameter settings.
In addition, the settings of the integrated potentiometers P1 … P4 must be taken into account.
4.2 Commissioning the motor starter
The SK 1x5E series can be commissioned in various ways:
a) For simple applications (e.g. conveyor applicatio ns) by means of the DIP switches integrated int o
the frequency device ( internal) and the exter nally accessible P 1 and P2 as well as the internal potentiometers P3 and P4.
b) By adaptation of parameters using software via the Param eterBox (SK CSX-3H or SK PAR-3H) or
NORD CON PC - supported software.
In order to permanentl y store the parameter in the flas h memory, the RAM values mus t be copied
from the RAM to the flash using parameter P550.
ATTENTION
DANGER TO LIFE!
The motor starter is not equipped with a

4.2.1 Connection
After mounting on the motor, the mains and motor cables must be connected to the relevant terminals
(PE, L1, L2, L3 and U, V, W) (see Section 2.5 and 2.6).
In addition, a 24V DC control voltage is essential
In principle, the motor starter can be operated in this configuration. (See Section 4.2.2.1)
NOTE
The necessary 24V control voltage can be implemented by in integrated (SK CU4-…-24V) or an
external (SK TU4-…-24V) optional mains unit or a comparable power source (min. 100mA)
(connection to terminals 44/40).

4.3 AS Interface
4.3.1 The bus system
The ActuatorSensor Interface (AS-Interface) is a bus system for the lower field bus level. The transfer
principle is a single-m aster system with cyclical polli ng. Up to 31 standard slaves ( or 62 A/B slaves in the
extended address range) can be operated on an unshielded two-wire cable up to 100m long and in any
network structure (tree / linear / star). For the AS-Interface, since the Complete Specification V2.1 a
differentiation is m ade between standar d and A/B slaves. T his version includes the doubling of the number
of slaves to 62. This is don e b y the d oub le-assignment of addres s es 1-31 and their designat ion as "A S la ve "
and "B Slave". A/B slaves are labelled via the ID code and can therefore be uniquely identified by the
master.
Type SK 1x5E motor starters are A/B sl av es , whic h co r r espond to slave profile S-7.A. They can be administered by masters whose profile at least corresponds to class M4.
In contrast to devices with the profile S-7.0 devices with the profile S-7.A use the extended address range.
Devices with slave pr ofiles S-7.0 and S-7.A can be jointl y operated with in an AS-i net work as of version 2.1
(Master profile M4) with observance of the allocation of addresses (see example).
Permissible
Standard slave 1 (Address 6)
A/B-Slave 1: (Address 7A)
A/B-Slave 2: (Address 7B)
Standard slave 2 (Address 8)
Standard slave 2: (Address 7)
Not permissible
Standard slave 1 (Address 6)
A/B-Slave 1: (Address 7B)
Standard slave 3 (Address 8)
The AS Interface cable ( yellow) transfers data an d energy. Addressing is carried out via the m aster, which
also provides further m anagement functions, or via a separate addressi ng device. The transfer of the 4 Bit
reference data (in each direction) is performed with effective error protection for standard slaves with a
maximum cycle time of 5ms. Due to the correspondingly higher num ber of participants, for A/B slaves the
cycle tim e (m ax. 10m s) is doubled for data which is sent from the sla ve to the m aster. Ex tende d addr essin g
procedures for the trans mission of data to the sla ve also cause an additi onal doubling of the c ycle time to
max. 21ms.
The bus system is com pletely defined in the AS-Interf ac e Com pl ete Specification and is standardised as per
EN 50295, IEC62026.

4.3.2 Features
SK 145E-ASI … SK 175-ASI motor starters provide an integrated AS interface as standard. Therefore,
these devices can be directly integrated into an AS interface network. Only the setting of various functions of
the motor starter (DIP switches or parameter), the addressing and the proper connection of the supply,
BUS, sensor and actuator cables need to be carried out.

jumpers)
• Connection to the motor starter via the terminal bar,
• Optional connection via M12 flange plug connector

4.3.3 Bus structure and technology
The AS interface network can be set up in any configuration. Linear, star, ring or tree structures are
possible. An existing network can be subsequently extended by the addition of further slaves. Up to 31
standard slaves (i.e. a m aximum of 124 binary sensor s and 124 binary actuator s) or 62 A/B slaves (i.e. a
maximum of 248 binary se nsors and 248 binar y actuators) can be connected t o an AS interfac e network or
an AS interface master . Each AS interface slave has its own addres s (1 to 31 (or 1A … 31A, 1B … 31B)),
which is assigned to the s lave with th e aid of an addr essing device, or is transfer red to the slave b y means
of a command from the AS interface master. Each slave address may only be assigned once.
Usually the AS interface master is a part or component of the control unit and f orms the interface between
the control unit and the connected s laves. A n AS m aster com municates in dependentl y and exc hanges dat a
with the connected AS-i slave options. Normal net work com ponents may not be used in an AS i nterface
network. Only a spec ial AS interface mains unit m ay be used f or the power supply of each AS int erface
strand. This AS interface power supply is connec ted directly to the yellow standard cable (ASI+ and A SIcable) and should be locat ed as close as possible to the AS -i master in order to keep the vo ltage drop as
small as possible.

Addressing
In order to use a m otor starter in an AS-i network, it must be assig ned a unique address (1-31/62) As the
default setting, the starter i s set to address 0 and can theref ore be recognised as a "new device" by an AS
master (condition for automatic allocation of address by the master).
In many other cases, ad dr e s s ing is car r ied o ut by means of a norm al addres s ing device for AS-i slaves. The
following should be noted:
Ensure power supply of the AS-i interface via the yellow AS-i cable.
• Disconnect the AS-i master during addressing
• Set the address ≠ 0
• Do not doubly assign addresses

Parallel control via the AS int erf ac e and v ia the two digital inputs is pos sibl e. The AS interface is detected as
normal digital inputs. If e.g. a manual-automatic switc hover is to be performed, it must be ensur ed that in
automatic mode there is no enable via the normal digital inputs. This could be implemented e.g. with a
three-position ke y switch. Position 1: "Manual left" P osition 2: "Automatic" Position 3 "Manual right". If an
enable is present via one of the two "normal" digital inputs, the control bits from the AS interface are
ignored. An exception is the control bit "Acknowledge fault". This function is always possible in parallel,
regardless of the control hierarchy. The AS interface can therefore only take over control if there is no
control via a digita l input. If "Ena ble left" and "Enable right " are set s imultaneousl y, the enable is c ancelled.
In the case of a soft start er (SK 115E, SK 135E, SK 155E and SK 175E) the motor would stop without a
deceleration ramp (voltage block).
In case of malfunc tion (interruption of com munication or break in the bus cable) t he motor starter sw itches
off automatically. In order to prevent a re-start on restoration of communication, the AS-i master must actively set the control bits to "Zero".

4.4 PROFIBUS
PROFIBUS DP allows the exchange of data between a wide range of automation devices. PLC's, PC's,
operating and monitoring devices can al l communic ate via a uniform bus in serial bit mode. P ROFIBUS DP
is primarily used for communic ation b etween sensor and ac tuator wher e system response needs to be ver y
fast. PROFIBUS is used where the time for rapid and complex communication between the individual
devices is critical. PRO FIBUS DP is a suitabl e alternative to expensive 2 4-volt parallel signa l transmission
and transmission of measured values. This type of PROFIBUS, which is optimised to speed, is used for
instance for operating frequency inverters on automation devices.
PROFIBUS communication is specified in the international standards IEC 61158 and IEC 61784. Application
and planning aspects are s pecif ied and documented i n the guidelines of the PRO FIBUS users´ organisation
(PNO). This ensures interc ommunication between devices f rom different manufacturers. Data ex change is
specified in DIN 1924 5 Part 1 and 2 and applicat ion-specif ic upgrades in Part 3 of this standard. W ithin the
European field bus standardisation pr ocess, PROFIBUS is integrated into th e European field bus standard
EN 50170.

Addressing of the starter is carried out via two decimal rotary coding switches, see the following illustration.
The PROFIBUS address of the starter can be set with in a range of 1 to 99 with the r otar y coding sw itch. If 0
is set, the starter interprets this value as 126. Reading of the address is carr ied out immediately after the
24V supply to the starter is switched on.
The address is set via two rotary coding switches. The switch labelled "x1 S3" gives the decimal range
between 0 and 9. The switch "x10 S2" multiplies the set value 0 to 9 by 10.
Example:
Switch S2 = 4
Switch S3 = 2

Operating behaviour in switch-off mode 1:
In this m ode, after sw itch-on, the torq ue
value (voltage) which is determined by
potentiometer 3 or P210 is applied to
the motor. The voltage is continua lly increased during the tim e which is set by
potentiometer 4 or P102, until the full
voltage is reached. On enabling, the
electromechanical brake is released.
When the enabling is rem oved, the voltage is continually r educe d from 100% to
0% over the period which is determined
by P4 or P103. The brake is applied after the ramp has elapsed.
Operating behaviour in switch-off mode 2:
In switch-off mode 2, t he drive behaves
in the same wa y as i n switch-off mode 1
when it is switched on. However , when
the enabling is rem oved, the voltage is
directly reduced to t he va lue determined
by potentiometer 3 or P210, and then
reduced to zero within the time which is
determined by potentiom eter 4 or P103.
Once again, the brake is applied after
the time has elapsed.
Operating behaviour in switch-off mode 3:
In this operating mode, the behaviour
on switch-on is identical to that in
switch-off mode 1. However, when the
enabling is removed, the motor switches
off immediately and the brake is also
applied immediately.
Operating behaviour in switch-off mode 4:
As for operating mode 3, however the
brake is applied with a delay, which is
determined by the value from potentiometer 4 / P107.

6 Operating status messages
According to the cause, motor starters generate appropriate messages if they deviate from their normal
operating status. There is a differentiation between warning and error messages. If the motor starter is in the
status "Start disabled", the reason for this can also be displayed.
Error and warning messages as well as the reasons for the "Start disabled" are displayed in the
corresponding arrays of parameter (P700).
Motor starter starting disabled
If the motor starter is in the s tatus "Not R e ady" or "Start Disabled", the reason for this is indicate d in th e thir d
array element of parameter (P700).
Warning messages
Warning messages are gener ated as soon as a defined lim it is reached. However this does not cause the
device to switch off. Thes e messages can be displa yed via the ar ray-e lem ent [-02] in param eter (P700) unt il
the reason for the warning is no longer present or the device has gone into a fault state with an error
message.
Error messages
Errors cause the motor starter to switch off, in order to prevent a device fault.
The following options are available to reset a fault (acknowledge):
1. Switching the mains off and on again,
2. By an appropriately progra mmed digital input (P420 = Function 7),
3. By switching the “enable” on the motor starter to Low (if no digital input is programmed for
acknowledgement),
4. By acknowledging via the AS interface or PROFIBUS
An error message can only be acknowledged if its direct cause is no longer present.

7.3 Electromagn et ic co mp at ib ility
As of July 2007, all electrical equipment which h as an intri ns ic, ind ep end ent f unc ti on and whic h is s old as an
individual unit for end users, must comply with Directive 2004/108/EEC (formerly Directive EEC/89/336).
There are three different ways for manufacturers to display compliance with this directive:
1. EC declaration of conformity
This is a declaration from the manufacturer, stating that the requirements in the applicable European standards for
the electrical environment of the equipment have been met. Only those standards which are published in the Official
Journal of the European Community may be cited in the manufacturer’s declaration.
2. Technical documentation
Technical documentation can be produced which describes the EMC characteristics of the device.
This documentation must be authorised by one of the ‘“Responsible bodies” named by the responsible European
government. This makes it possible to use standards that are still under preparation.
3. EC type test certificate (This method only applies to radio transmitter equipment.)
SK 1x5E motor starters only have an intrinsic function when they are connected to other equipment (e.g. with a
motor). The basic units cannot therefore carry the CE mark which would confirm compliance with the EMC directive.
Precise details are therefore given below about the EMC behaviour of this product, based on the proviso that it is
installed according to the guidelines and instructions described in this documentation.
Class A devices (Group 2):
Class A is for equipment of the normal class and is intended for use in an indu strial environment. Devices
which are installed at a loc ation which is covered by this categ ory are not connected directl y to the public
low voltage supply grid, but rather, they are connected to an industrial grid with an assigne d transformer.
If the standards for equipm ent class A are n ot sufficient in a spec ial industrial en vironment, e.g. if sensitive
measuring channels may be affected, the user must request class B equipment.
Class B equipment:
Class B equipm ent is required if it is used in a commer cial and sm all-scale indus trial enviro nment and is to
be connected directly to the public low voltage supply grid. The equipment class must be stated by the
manufacturer in the product information.
ATTENTION
SK 1x5E motor starters are designed solely for commercial applications. They are
therefore not subject to the requirements of the standard EN 61000-3-2 for radiation of
harmonics.
This device produces high frequency interference, which may make additional suppression
measures necessary in domestic environments.

8.1 Maintenance and servicing information
8.1.1 Maintenance Instructions
SK 1x5E motor starters are maintenance free in normal operation. Please note the "general data" in
Section 7.1 .
Dusty environments
If the motor starter is used in a dusty environment, the cool ing-vane surfaces should be r egularly cleaned
with compressed air.
Long-term storage
The motor starter must be connected to the 24V supply at regular intervals.
If this is not carried out, there is a danger that the devices may be destroyed.
If the device is stored for l onger than one year, it m ust only be connected to its 24V su pply for 30 minutes
before it is connected to the normal mains.
