The SK 1x5E-FDS series is based on the tried and tested NORD platform. The devices are
characterised by their compact design and their optimum operational characteristics, and have uniform
parametrisation.
Due to dual phase control, not only a pure motor start, but also a soft start is possible. The phase
control process was selected so that the resulting harmonic torques are kept as low as possible. A
comprehensive spectrum of monitoring functions rounds off the range.
Due to the numerous setting options, any three-phase synchronous motor can be controlled.
The motor starter is basically intended for a three-phase mains connection. The power range is from
0.25 kW to 3.0 kW.
This series of devices can be adapted to individual requirements by means of modular assemblies.
This manual is based on the device software specified in the version list (see P707). If the motor
starter uses a different software version, this may cause differences. If necessary, the current manual
can be downloaded from the Internet (http://www.nord.com/).
Additional descriptions exist for optional functions and bus systems (http://www.nord.com/).
Information Accessories
Changes may also be made to the accessories that are mentioned in the manual. Current details of these are
included in separate data sheets, which are listed under www.nord.com under the heading Documentation →
Manuals → Electronic drive technology → Techn. Info / Data sheet. The data sheets available at the date of
publication of this manual are listed by name in the relevant sections (TI ...).
The different versions of the device series also result in different functionality (e.g.: with integrated AS
Interface or with integrated PROFIBUS DP interface).
In the simplest configuration, all of the most important parameters can be set using up to four
potentiometers and four DIP switches, even without a PC or a control unit. LEDs are provided for the
diagnostics of the operating status. The use of a control module is therefore not absolutely necessary.

A typical feature of this frequency inverter series is their installation close to the motor, e.g. on the wall
or on a machine frame.
All electrical connections (power connections and control connections) are made with plug connectors.
This considerably simplifies the installation of the frequency inverter and opening the FI is not
necessary.
In order to obtain access to all parameters, the internal RS232 interface (access via RJ12 connection)
can be used. Access to the parameters is made e.g. via an optional SimpleBox or ParameterBox.

The parameter settings modified by the owner/operator must be saved in the Flash memory of the
device (P550). Otherwise the changed parameter settings would be lost when the device was
switched off.

The frequency inverter is configured according to the customer's individual requirements.
Configuration is therefore performed at the factory. Retrofitting of options or conversions are not
intended.

Information
The frequency inverter must not be opened.
The frequency inverter must not be opened at any time during its service life. As in normal operation, all
assembly, installation and commissioning is only carried out with the FI closed.
• Assembly is carried out via freely accessible mounting holes.
• Electrical connections are made exclusively with plug connectors..
• Operating settings are made by changing parameters or with DIP switches and potentiometers. Access to
these elements or for connecting a parameterisation tool is via blank plugs. These blind plugs may only be
removed for work associated with commissioning and must then be properly refitted.
• Diagnostic LEDs to indicate switching and operating states are externally visible.

1.1 Overview
This manual describes all of the possible functions and equipment. The configuration and functionality
are limited according to the type of device. SK 175E-FDS frequency inverters have additional
integrated characteristics for the maximum configuration.
Basic characteristics
• Wall mounting close to the motor.
• 5 digital inputs a), b)
• 2 digital outputs b)
• Separate temperature sensor input (TF+/TF-) b)
• Motor overload protection (I2t triggering characteristic in accordance with EN 60947) This means
that a motor protection switch is not needed, merely an input fuse!
• Mains and motor phase failure monitoring
• Flux monitoring (minimum current monitoring)
• Automatic phase sequence detection
• Permissible ambient temperature -25 °C to 50 °C (please refer to the technical data)
• Integrated EMC mains filter for Class A limit values
• 2 x DIP switches and 3 x potentiometers for configuration
• Diagnostic LEDs (incl. signal status DIs/ DOs)
• RS232 / RS485 interface via RJ12 plug connector, alternatively USB (only RS232)
• 24 V DC control voltage
– Must be provided via a plug connector, or
– Can be provided by the FI (only with option –HVS).
It is also possible to connect an external 24 V DC voltage supply via an optional plug connector
in order to supply a high power peripheral (e.g. actuator).
• Integrated PLC (BU 0550)
a) If necessary, individual inputs can be defined at the factory by use
of certain optional modules.
b)
Connection is only possible with optional plug connectors.
Additional features
There are two versions of the frequency inverters (-ASI) with integrated AS interface and (-PBR) with
integrated PROFIBUS DP.
Differences between the individual versions (SK 155E-FDS / SK 175E-FDS) are summarised in the
following table and are described in this manual.

Optional features
The FI can be individually adapted to the drive task. For this, a comprehensive selection of interfaces,
plug connections and control elements are available, which can be used during the manufacture of the
FI according to the customer's requirements.
Depending on the configuration, the meaning of the individual LEDs, function or assignment of
individual plug connectors or the function of control elements (e.g. switches) may differ. The possible
combinations will be illustrated and explained in the course of this manual. The individual configuration
of the FI can be identified using the type plate and can be compared with the details in the manual.

1. General
Do not use defective devices or devices with defective or damaged housings or missing covers (e.g.
blind plugs). Otherwise, there is a risk of serious injury or death from electric shock.
Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of
serious personal injury or material damage.
During operation, depending on their protection class, devices may have live bare components as well
as hot surfaces.
The device operates with a dangerous voltage. Dangerous voltage may be present at the supply lines,
contact strips and PCBs of all connecting terminals (e.g. mains input, motor connection), even if the
device is not working or the motor is not rotating (e.g. caused by electronic disabling, jamming of the
drive or a short circuit at the output terminals).
The device is not equipped with a mains switch and is therefore always live when connected to the
power supply. Voltages may therefore be connected to a connected motor at standstill. An optional
mains connection outlet is also at mains voltage.
Even if the drive unit has been disconnected from the mains, a connected motor may rotate and
possibly generate a dangerous voltage.
If you come into contact with dangerous voltage such as this, there is a risk of an electric shock, which
can lead to serious or fatal injuries.
Power plug connectors must not be pulled out when they are connected to the power supply. Failure
to comply with this may cause arcing, which in addition to the risk of injury, also results in a risk of
damage or destruction of the device.
The fact that the status LED or other indicators are not illuminated does not indicate that the device
has been disconnected from the mains and is without voltage.
Metal components and the housing of power plug connectors may heat up to temperatures of more
than 70°C.
Touching these parts can result in local burns to the body parts concerned (cooling times and
clearance from neighbouring components must be complied with).
All work on the device, e.g. transportation, installation, commissioning and maintenance work must be
carried out by qualified experts (observe IEC 364 or CENELEC HD 384 or DIN VDE 0100 and
IEC 664 or DIN VDE 0110 and national accident prevention regulations). In particular, the general and
regional installation and safety regulations for work on high voltage systems (e.g. VDE) must be
complied with as must the regulations concerning correct use of tools and the use of personal
protection equipment.
During all work on the device, take care that no foreign bodies, loose parts, moisture or dust enter or
remain in the device (risk of short circuit, fire and corrosion).
Further information can be found in this documentation.
