1 General
The SK 1x5E 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 7.5 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
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
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 ...).
Accessories
under the heading Documentation →
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.
Installation directly on a motor is typical of this device series. Alternatively, optional accessories are
also available for mounting the devices close to the motor, e.g. on the wall or on a machine frame.
In order to have access to all parameters, the internal RS232 interface (access via RJ12 connection)
can be used. Access to the parameters takes place via an optional SimpleBox or ParameterBox, for
example.
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.

Option modules
Option modules are used to extend the functionality of the device.
These options are available as an installation variant, the so-called SK CU4-… customer unit, and also
as an attachment variant, the so-called SK TU4-… technology unit. As well as the mechanical
differences, the installation and attachment variants also have some functional differences.
Figure 1: Device with internal SK CU4-... Figure 2: Device with external SK CU4-...
Attachment variant
The external technology unit (Technology Unit SK TU4-…) is externally attached to the device and
is therefore easy to access.
A technology unit basically requires the use of a suitable SK TI4-TU-… connection unit.
The power supply and signal lines are connected using the screw clamps of the connection unit.
Depending on the version, additional connections for connectors (e.g. M12 or RJ45) may be available.
The optional wall mounting kit SK TIE4-WMK-TU also allows the technology units to be mounted away
from the starter.
Built-in variant
The internal customer unit (Customer Unit, SK CU4-...) is integrated in the device. The power
supply and signal lines are connected using screw clamps.

1.4 Safety, installation and operating instructions
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 for cable glands). Otherwise there is a risk of serious or fatal injuries caused by electric
shock or bursting electrical components such as powerful electrolytic capacitors.
Unauthorised removal of covers, improper use, incorrect installation or operation causes a risk of
serious personal injury or material damage.
During operation and depending on the protection class of the devices, there may be live, bare,
moving or rotating parts or 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.
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.
The device and any power plug connectors must not be disconnected while a voltage is applied to the
device. 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.
The heat sink and all other metal components can heat up to temperatures above 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.

Cable laying
For all versions, care must be taken that the cables and the cable glands at least comply with the protection class
of the device and the attachment regulations and are carefully matched. The cables must be inserted so that
water is deflected away from the device (if necessary use loops). This is essential to ensure that the required
protection class is maintained.
IP55 version:
The IP55 version is the standard version. In this version, the two installation types motor mounted
(fitted onto the motor) and close coupled (fitted to the wall bracket) are available. All adapter units,
technology units and customer units are also available for this version.
IP66 version:
The IP66 version is a modified option of the IP55 version. Both installation types (motor-integrated,
close coupled) are also available for this version. The modules available to the IP66 design (adapter
units, technology units and customer units) have the same functionalities as the corresponding IP55
design modules.
The modules for the IP66 version are identified by an additional "-C" in the type key, and are modified with the
following special measures:
• impregnated PCBs,
• Powder coating RAL 9006 (white aluminium) for housing,
• modified blank screw caps (UV-resistant),
• Low pressure test.
IP69K version:
The IP69K version is a modified option of the IP66 version. In device with protection class IP69K, the
housing is made from nsd-tupH. Both installation types (motor-integrated, close coupled) are also
available for this version.

The devices are available in various sizes depending on their output. They can be mounted on the
terminal box of a motor or in its immediate vicinity.
Motor-mounted version Wall-mounted version
When a complete drive unit (gear unit + motor + SK 1x5E) is delivered, the device is always fully
installed and tested.
IP6x-compliant devices must be installed by NORD, since special measures have to be implemented. IP6x
components that are retrofitted on site cannot ensure that this protection class is provided.
When delivered separately, the device includes the following components:
• SK 1x5E
• Screws and contact washers for mounting the motor terminal box
• Pre-fabricated cable for motor and PTC connections
The sizes of the device series only differ with regard to their possibilities for adapting to the matching
motors. For example, size 1 is coordinated with motor sizes 80 – 100, and size 2 is coordinated with
motor size 132. The external dimensions (envelope dimensions) of the devices are identical.
