1 Introduction
This document serves for the migration of drive solutions with SK 700E series frequency inverters to
the new model SK 500E. As well as the comparison and migration of the usual modules in the first
part of the document, the middle part deals with the comparison of the connection terminals and the
final part describes the dimensions of the devices.
Both series (SK 700E and SK 500E) are similar in their basic structure, however the performance and
scope of functions of the new series has been considerably increased. Until the end of 2013, the
SK 5xxE will also be available up to size 11 (160.0 kW) for the identical power range of the SK 700E.
The comparison only covers the 3 ph ~ 400 / 480 V types of frequency inverters. The present
document only describes the functions and solutions which could also be implemented with the
SK 700E. In addition, in the description of possible options, only the most common have been
described and listed in detail. The Migration Guide MI 0700 also compares the respective additional
components.

Information
Integrated mains filter
The SK 700E frequency inverters of power range 1.5 kW to 22.0 kW listed above come with an integrated mains
filter of class A by default and are identified with abbreviation -A in the type code. SK 700E frequency inverters
with a power ≥30.0 kW do not feature an integrated mains filter and are identified with abbreviation -O in the type
code. All SK 5xxE frequency inverters (complete power range from 1.5 kW to 160 kW) come ex factory with an
integrated Class C2 (industrial) mains filter. With motor cable lengths ≤ 5 m, the SK 5xxE frequency inverters in
the power range 1.5 kW to 7.5 kW even comply with Class C1 (residential and industrial). All SK 5xxE frequency
inverters feature an on board integrated mains filter and are identified with abbreviation -A in the type code.
For information on the mains filter functions of SK 700E- …-Aor … -O frequency inverters with and without
integrated mains filter, please refer to the respective manual (BU 0700) (www.nord.com).

Frequency inverters of the SK 5xxE series come in 10 different performance levels (SK 500E,
SK 505E, SK 510E, SK 511E, SK 515E, SK 520E, SK 530E, SK 535E, SK 540E, SK 545E). In
general, a distinction is made between SK 5x0E and SK 5x5E devices.
Sizes 1 to 4 of the SK 700E frequency inverters (1.5 kW to 22.0 kW) always come with a shield
bracket fitted to the frequency inverter housing. Shield clamps (size 8 to 35) specific to the cable cross
section and size are not supplied ex factory and, if necessary, will be provided and/or mounted by
persons charged with installation while fitting and setting up the SK 700E frequency inverters.
When migrating an application to the SK 5xxE series of frequency inverters you should always
provide for an additional EMC kit suitable for type SK EMC 2-x according to the size.

NOTICE
Encoder supply voltage
Incremental encoders with 5 V supply voltage can be directly operated with frequency inverters of the SK 700E
series. For the SK 5xxE series of frequency inverters, the connected incremental encoders must be suitable for a
supply voltage range of 10 V … 30 V.
This is why the incremental encoders must be replaced or the "old" encoders must be supplied from an external
power supply when migrating to SK 5xxE frequency inverters.

NOTICE
Encoder supply voltage
Incremental encoders with 5 V supply voltage can be directly operated with frequency inverters of the SK 700E
series. For the SK 5xxE series of frequency inverters, the connected incremental encoders must be suitable for a
supply voltage range of 10 V … 30 V.
This is why the incremental encoders must be replaced or the "old" encoders must be supplied from an external
power supply when migrating to SK 5xxE frequency inverters.
Table 6: Overview of SK 5xxE performance levels for POSICON positioning control
When using the onboard CAN / CANopen interface of ≥ SK 511E frequency inverters, it is mandatory to connect
an additional 24 V power supply for the CAN / CANopen Bus to the RJ45 sockets.
For easier cabling and connection of functions (for 24 V supply and CAN / CANopen bus connection cables), the
WAGO adapter module RJ45/terminal (see chapter 2.1.3 Additional options for the functions) can be used with
conventional patch cables.

2.1.2 Customer units and extension units
To connect I/O control signals to the SK 700E frequency inverters, additional SK CU1-xxx IO
customer units are required. In contrast, the SK 5xxE series of frequency inverters by default comes
with respective onboard terminals to connect the standard I/O control signals.
When migrating to an SK 500E frequency inverter, you should provide for a performance level ≥
SK 511E with integrated onboard CAN / CANopen interface for SK 700E field bus customer units of
SK CU1-CAN and SK CU1-CAN-RJ types.
For the SK 5xxE series of frequency inverters, only one of the two PROFIBUS DP technology units
type SK TU3-PBR or …-24V can be planned in connection with a SK 700E PROFIBUS DP field bus
customer unit type SK CU1-PBR.
Special extensions ENCODER / incremental encoder input type SK XU1-ENC and the POSICON
positioning control SK XU1-POS of the SK 700E frequency inverter are migrated to the SK 5xxE
series of frequency inverters with different performance levels such as the SK 52xE (with ENCODER /
incremental encoder input) or the SK 53xE (with POSICON / positioning control) series.
The sub-chapters to follow list some differences in function of the two series of frequency inverters
that must be heeded under all circumstances which must be taken into account when migrating from
the SK 700E to the SK 5xxE series or when migrating applications:

The IO extension SK EBIOE-2 (275900210) can be used to connect the 2nd analogue output (0…10 V) and the two
analogue inputs (-10 V…+10 V). Thus, additional ±10 V setpoint converters (278910320) are not needed.
****
The analogue 0…10 V output signal of SK 5xxE frequency inverters must be converted to 0/4…20 mA with a
commercially external signal converter.

If next to the PROFIBUS DP customer unit SK CU1-PBR an operation and diagnostic technology unit is also used
with the SK 700E application, a SimpleBox SK CSX-0 or a handheld control box SK PAR-3H or SK CSX-3H should
be planned for SK 5xxE application, in addition to the technology unit SK TU3-PBR for frequency inverter operation.
The connection types of the two different PROFIBUS DP field bus options also differ. PROFIBUS DP connection to
the SK CU1-PBR customer unit occurs via spring loaded terminals. PROFIBUS DP connection to the technology unit
SK TU3-PBR or SK TU3-PBR-24V occurs at the front with a 9-pole SUB-D connector (must be provided separately).
For more information refer to the PROFIBUS DP Supplementary Operating Instructions BU 0020 (see
www.nord.com).
******
The WAGO adapter module RJ45 / terminal (278910300) and commercially available pre-assembled RJ45 patch
cables allow for easy connection of the additional external 24 V power supply for the CAN bus and the CAN
connection cables.
*******
All frequency inverters ≥ SK 520E feature the RS485 interface next to the RJ12 on connector block X11 and also on
terminal block X7 or terminals 74 and 75.

Encoder supply voltage
Rotary encoder with 5 V power supply must not be connected to the SK 5xxE frequency inverters directly. For
this application, a commercially external power supply should be used because the SK 5xxE frequency inverters
only feature a 10…30 V output for connection of a incremental encoder.
This is why the rotary encoders must be replaced or the "old" encoders must be supplied from an external 5 V
power supply when migrating to SK 5xxE frequency inverters.
Table 9: Overview and assignment of extension units SK XU1-xxx
The WAGO adapter module RJ45/terminal comes with a shield clamp and is used to connect the CAN bus cable
sand the external necessary 24 V power supply for the CAN / CANopen bus system. Signal connection occurs
with spring terminals on the input side and an RJ45 western socket on the output side. This adapter module
RJ45/terminal facilitates the connection of the CAN bus system to frequency inverters of performance levels ≥
SK 52xE.
For more information and details, please refer to the operating instructions of the frequency inverter.
Information
Setpoint converter ± 10 V
The setpoint converter ± 10 V is used to convert the signal for the analogue inputs of unipolar (0 … 10 V and
0 / 4 … 20 mA) to bipolar (- 10 V … + 10 V) voltages. SK 5xxE frequency inverters of size 5 (≥ 11 kW) and higher
can process unipolar and also bipolar analogue inputs by way of configuration with DIP switches.
For more information and details, please refer to the operating instructions of the frequency inverter.
Information
IO extension
IO extension SK EBIOE-2 lets you connect additional IO control signals and is suitable for SK 540E or SK 545E
frequency inverters.

To connect more digital inputs (acc. to SK XU1-POS) to the SK 545E frequency inverter, the optional IO extension
SK EBIOE-2 (275900210) is offered. Connection of the analogue inputs ± 10 V to the SK 545E frequency inverters occurs
directly to the terminal block X4 of the SK 545E from size 5 onward.
As an alternative, the ± 10 V analogue inputs can also be connected with terminal blocks X1 + X2 (see TI 275900210) when
an IO extension of type SK EBIOE-2 (275900210) is used.
**
Commercially available external signal converters are necessary if the analogue outputs of the SK 5x5E frequency inverters
are used and signal conversion to 0/4 … 20 mA compatible with SK CU1-MLT-20mA is necessary.
As an alternative, connection could occur to terminal block X2 (see TI 275900210) if only one0/4 … 20 mA analogue
output is used in conjunction with an SK 545E frequency inverter and a type SK EBIOE-2 (275900210) IO extension.

Information
EMC kit SK EMC2-x
The EMC Kit provides the possibility of attaching the screening of the motor cable to a large surface of the
frequency inverter (interference source). If necessary a screened brake resistor cable can be attached with the
second hammer clamp. The screening angle is attached to the two housing screws on the lower edge (below the
U-V-W terminals). The motor cable screening is earthed to a large area of the screening angle by means of the
hammer clamp. As an alternative, you can also use the EMC kit as a strain relief only (e.g. for connection cable of
a bus system) (heed bending radii!).
For more information and connection details, please refer to the operating instructions BU 0500 or BU 0505 (see
www.nord.com) for the SK 5xxE frequency inverter series.

or C1 mains filter (only sizes 1 to 4) for a maximum motor cable length of 5 m and shielded motor
cable. For a maximum motor cable length of 20 m and shielded motor cable, the internal mains filter
complies with EMC limit value classes A or C2 (all sizes). In order to comply with a higher radio
interference suppression level Class B or C1, adaptive mains filters as external accessories for
frequency inverter operation can be used with longer motor cables. There are two versions of these
external mains filters that are to reduce the emissions of electrical interference.

2.7 Chokes
Chokes are inductive, passive components used for current limitation, interference suppression and
damping of undesired harmonic content.
There are two types of chokes: input and output chokes.
Choke type
• Input choke (mains choke)
• Output choke (motor choke)
Figure 7: Choke types
Both choke types are available for the entire power ranges of the SK 700E and also the SK 5xxE
frequency inverters from 1.5 kW to 160.0 kW.
To reduce harmful mains voltage peaks or mains voltage fluctuations, adaptive input chokes of type
SK CI1-4x0/xxx-C can be connected upstream of the frequency inverter if required by the system.
The use of input chokes considerably reduces external mains feedback effects and the proportion of
current harmonics to a minimum.
To improve the EMC characteristics and for safety reasons, output chokes of type SK CO1-4x0/xxx-C are often implemented between frequency inverter and the motor in case of long motor cables. They
reduce the electromagnetic radiation emitted by the motor cable or provide cable compensation in
case of long motor cables. For more details regarding the allocation of the respective input and output
chokes, refer to the following sub-chapters.
It is recommended that an input choke is always used for frequency inverters with a power of more than 45 kW.
As a rule, you can continue using existing input chokes of type SK CI1-460/xxx-C of the SK 700E for the SK 5xxE
when migrating from the SK 700E to an SK 5xxE frequency inverter. For new installations and system extensions
with an SK 5xxE frequency inverter, an input choke of type SK CI1-480/xxx-C with higher rated voltage (see
tables below) should be planned and implemented.

Output choke
We recommend using an output choke with motor cables longer than 100 m (unshielded) or longer than 30 m
(shielded). As a rule, you can continue using existing output chokes of type SK CO1-460/xxx-C of the SK 700E
for the SK 5xxE when migrating from the SK 700E to an SK 5xxE frequency inverter.
For new installations and system extensions with an SK 5xxE frequency inverter, you should always plan and
implement an SK CO1-480/60-C with higher rated voltage in the power range of 18.5 kW to 300 kW.
All available output chokes for both frequency inverter series have been designed for a frequency inverter pulse
frequency of3 to 6 KHz only!

2.8 Braking resistors
External braking resistors are available as accessory for the SK 700E-xxx-340-A (-RS2) and also the
SK 5xxE-xxx-340-A frequency inverters.
Both frequency inverter series feature integrated brake choppers, to absorb the fed back energy
(resulting from dynamic brake actions) using an external braking resistor.
There are two versions of these external braking resistors that are used to prevent overvoltageinduced switch-off actions of the frequency inverters.
Version
• Footprint braking resistor
• Chassis braking resistor
Figure 8: Braking resistor versions
The footprint braking resistors of type SK BR1-xxx/xxx-F for SK 700E frequency inverters are only
available for the power range of 1.5 kW to 7.5 kW. For SK 5xxE frequency inverters, footprint braking
resistors of type SK BR4-xxx/xxx are available for the power range of 1.5 kW to 7.5 kW.
The chassis braking resistors of type SK BR2 –xxx/xxx-C are available for the entire power range
of SK 700E frequency inverters from 1.5 kW to 160.0 kW.
For application with an SK 5xxE frequency inverter, the identical - depending of the resistance chassis braking resistors BW SK BR2-xxx-xxx-C can only be used in the power range from 3.0 kW to
160.0 kW. For more details regarding the allocation of the respective braking resistors, refer to the
following sub-chapters.

The tables below list and compare the footprint braking resistors SK BR1-xxx/xxx-F or SK BR4xxx/xxx allocated to the power ranges. The footprint braking resistors types/versions are different for
both series of frequency inverters. Depending on the available space and the respective switch
cabinet depth, both footprint braking resistor versions can be mounted either flat or vertically (book
size) next to the frequency inverter. For thermal protection of the footprint braking resistor of type
SK BR4-xxx/xxx, an optional temperature sensor (bimetal, 100 °C switching point, Part No.
275991200) can be fitted. Both footprint braking resistor versions are UL-approved and, because of
their protection class IP40, can also be installed outside the switch cabinet for improved heat
dissipation. For this purpose, the connection cables of the footprint braking resistors must be extended
accordingly.
As the chassis braking resistors SK BR2 -xxx/xxx-C are used for both series of frequency inverters (SK 5xxE and
SK 700E), there is no allocation to the frequency inverter power levels in the present chapter.

2.8.2 Chassis braking resistors
Various sizes of the chassis braking resistors SK BR2-xxx/xxx-C are available for both frequency
inverter series (SK 700E and SK 5xxE) and all available frequency inverter power levels up to
160.0 kW. There are two types/sizes, type 1 and type 2. The chassis braking resistors or resistor
elements are integrated into a housing grating and can be used universally. The chassis braking
resistors come with an integrated temperature sensor (bimetal) ex-factory. The temperature sensor
can be connected to a digital input of the frequency inverter with two terminals (4 mm²), and one of the
safety functions ("Block voltage" or "Emergency stop ") can be programmed.
Both chassis braking resistor versions are UL-approved and, because of their protection class IP20,
can also be installed outside the switch cabinet for improved heat dissipation. For this purpose, the
chassis braking resistors have to be connected to the respective frequency inverter via a separate
connection cable, a shielded cable is recommended. The connection cable should be as short as
possible.

Information
Analogue input (differential input)
When using the analogue input of the Basic I/O SK CU1-BSC customer unit , implemented as differential input, it
must be taken into consideration that the SK 5xxE frequency inverters only feature non-isolated analogue inputs!
This also applies to the basic I/O of type SK CU1-STD for SK 700E frequency inverters.
3.2.1 I/O customer units
To connect I/O control signals to the SK 700E frequency inverters, 6 different I/O customer units are
offered. In contrast, the SK 5xxE series of frequency inverters by default comes with respective
onboard terminals to connect the I/O control signals. Please heed the differing terminal
numbers/terminal names (e.g. terminal 42 / VO 15V, terminal 44 / VI 24V or VO 24V) for the different
power supplies of inputs and outputs of the SK 5xxE frequency inverter types or sizes.

The setpoint converter ±10 V (278910320) is only needed for sizes 1 to 4 (1.5 kW to 7.5 kW) of all SK 5xxE frequency
inverters. In case of applications with frequency inverters ≥ size 5 and ±10 V signals at the analogue inputs, only SK 54xE
types of frequency inverters should be used.
***
The IO extension SK EBIOE-2 (275900210) can be used to connect the 2nd analogue output (0…10 V) and the two
analogue inputs (-10 V…+10 V). Thus, additional ±10 V setpoint converters (278910320) are not needed. The IO extension
SK EBIOE-2 can only be connected to SK 540E and SK 545E frequency inverters. For more information, refer to the
Technical Information TI 275900210 (see www.nord.com).

3.2.2 Field bus customer units
To connect field bus systems (incl. some I/O control signal terminals) to the SK 700E frequency
inverters, 4 different field bus customer units are offered. In contrast, the SK 5xxE series of frequency
inverters by default comes with respective onboard terminals to connect some field bus systems and
some I/O control signals. Please heed the differing terminal numbers/terminal names (e.g.
terminal 42 / VO 15V, terminal 44 / VI 24V or VO 24V) for the different power supplies of inputs and
outputs of the SK 5xxE frequency inverter types or sizes.

For more information on the two onboard RJ45 CAN bus sockets (X9 and X10), please refer to manuals BU 0060, BU 0500
or BU 0505 (see www.nord.com). The CAN onboard function is only available for all frequency inverter types ≥ SK 511E. To
use the CAN / CANnord functions of the SK 5xxE frequency inverters, the CAN bus requires an external 24 V voltage supply.
Connection of the external 24 V supply occurs via the two RJ45 sockets X9 or X10, pin 3 or 7 for CAN_GND and pin 8 for
CAN_24V.
More information on the WAGO adapter module RJ45 / terminal, see chapter 2.1.3 Additional options for the functions.

Connection of the motor temperature sensor of PTC to the SK 700E series of frequency inverters
occurs by way of one of the digital inputs of the customer units or extension units. Depending on the
size of the PTCs, connection to the SK 5xxE series of frequency inverters occurs via digital inputs
(preferably DI 5) or, with size ≥ 5, via separate terminals T1 and T2 of terminal block X15.

Contrary to the SK 700E, the SK 5xxE frequency inverters
cannot be mounted directly with their rear in a switch cabinet but
with two (sizes 1 – 4) or four (sizes 5 – 7) supplied wall mount
bracket.
SK 5xxE frequency inverters ≥ size 8 feature an assembly
