1 General
The SK 1x5E-FDS series is based on the tried and tested NORD platform. The devices are
characterised by their compact design and optimum operating characteristics, and have uniform
parametrisation.
A two-phase phase section enables both motor start and soft start. The phase section procedure is
chosen so that the resulting alternating torques are kept as low as possible. A comprehensive
spectrum of monitoring functions rounds off the portfolio.
Thanks to the versatile setting options, all three-phase asynchronous motors can be operated.
The motor starter is principally designed for a three-phase mains connection. The power range is from
0.25 kW to 3.0 kW.
The device series can be adapted to individual requirements by means of modular assemblies.
This manual is based on the device software as stated 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
The accessories listed in the manual are also subject to changes. Current details of
these are
included in separate data sheets, which you can find under http//www.nord.com/ under the heading
Documentation → Manuals → Electronic drive technology → Find techical information/data sheet.
The data sheets available at the date of publication of this manual are listed by name in the relevant
sections (TI ...).
The device series’ various versions result in differences between the functionalities (e.g. with
integrated AS-Interface or integrated PROFIBUS DP bus interface).
The simplest configuration allows for the setting of all important parameters using up to four
potentiometers and four DIP switches without a PC or control device. LEDs are available for
diagnosing the operating states. The use of a control module is therefore not mandatory.
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 device is configured according to the customer’s individual requirements. The device equipment is
therefore realised ex works. Later retrofittings of options or device conversions are not planned.

1.4 Safety, installation and application information
Before working on or with the device, please read the following safety instructions extremely carefully.
Please pay attention to all other information from the device manual.
Non-compliance can result in serious or fatal injuries and damage to the device or its surroundings.
These safety instructions must be kept in a safe place!
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.
2. Qualified experts
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.

1 General
BU 0155 en-3520 15
Furthermore, the device and the associated accessories may only be installed and started up by
qualified electricians. An electrician is a person who, because of their technical training and
experience, has sufficient knowledge with regard to
• switching on, switching off, isolating, earthing and marking power circuits and devices,
• proper maintenance and use of protective devices in accordance with defined safety standards.
3. Correct purpose of use – general
The Motor starters are devices for industrial and commercial plants for operating three-phase
asynchronous motors with squirrel-cage rotors.

Installation, maintenance and repair work must not be carried out unless the device has been
disconnected from the voltage and at least 5 minutes have elapsed since the mains was switched off!
(Due to charged capacitors, the equipment may continue to carry hazardous voltages for up to 5
minutes after being switched off at the mains). Before starting work it is essential to check by
measurement that all contacts of the power plug connections or the connection are voltage-free.
The electrical installation must be implemented according to the applicable regulations (e.g. cable
cross-section, fuses, earth lead connections). Further instructions can be found in the documentation
or manual for the device.
Information regarding EMC-compliant installation such as shielding, earthing, location of filters and
routing of cables can be found in the documentation for the devices and in the technical information
manual TI 80-0011. This information must always be observed even with inverters with a CE label.
Compliance with the limit values specified in the EMC regulations is the responsibility of the
manufacturer of the system or machine.
In case of a fault, inadequate earthing may result in electric shock, possibly with fatal consequences.
The device may only be operated with effective earth connections which comply with local regulations
for large leakage currents (> 3.5 mA). Detailed information regarding connections and operating
conditions can be obtained from the technical Information manual TI 80-0019.
Connection of the supply voltage may directly or indirectly set the inverter into operation. Contact with
electrically live components will result in electric shock, possibly with fatal consequences.
All poles of cable connections (e.g. power supply) must always be disconnected.
Set-up, troubleshooting and commissioning
When working on live devices, the applicable national accident prevention regulations must be
complied with (e.g. BGV A3, formerly VBG 4).
The voltage supply of the device may directly or indirectly put it into operation, or touching electrically
conducting components may then cause an electric shock with possible fatal consequences.
The parametrisation and configuration of the devices must be selected so that no hazards can occur.
With certain setting conditions, the device or the motor which is connected to it may start automatically
when the mains are switched on. The machinery which it drives (press / chain hoist / roller / fan etc.)
may then make an unexpected movement. This may cause various injuries, including to third parties.
Before switching on the mains, secure the danger area by warning and removing all persons from the
danger area.
Operation
Where necessary, systems in which the devices 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.).
All covers must be kept closed during operation.
With certain setting conditions, the device or the motor which is connected to it may start automatically
