Safety and operating instructions
for the drive power converter
(as per: Low voltage guideline 73/23/EEC )
1. General information
During operation, drive power converters may have, depending on
their protection class, live, bare, moving or rotating parts or hot
surfaces.
Unauthorised removal of covers, improper use, incorrect
installation or operation leads to the risk of serious personal injury
or material damage.
Further information can be found in this documentation.
All transportation, installation and 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 erection,
installation, commissioning and operation of this product and who
have the relevant qualifications for their work.
2. Intended use
Drive power converters are components intended for installation in
electrical systems or machines.
When being installed in machines, the drive power converter
cannot be commissioned (i.e. implementation of the proper use)
until it has been ensured that the machine meets the provisions of
the EC directive 89/392/EEC (machine directive); EN 60204 must
also be complied with.
Commissioning (i.e. implementation of the proper use) is only
permitted when the EMC directive (89/336/EEC) is complied with.
The drive power converters meet the requirements of the low
voltage directive 73/23/EEC. The harmonised standards in prEN
50178/DIN VDE 0160, together with EN 60439-1/VDE 0660 Part
500 and EN 60146/VDE 0558 were applied for the drive power

1 General information
The series NORDAC SK 700E is the follow-on development of the proven vector series. These devices are characterised by
the high modularity and excellent control characteristics.
These devices are provided with non-sensor vector current control system which constantly ensures an optimised voltage-tofrequency ratio in combination with a motor model of an three-phase asynchronous motor. This has the following significance
for the drive: Peak start-up and overload torques at constant speed.
Due to its modular construction, the variously combinable technology units, customer units and special extension units, this
device series is suitable for all possible applications.
Devices for constant load:
Due to the numerous setting options, these inverters are capable of controlling all three-phase motors. The performance range
goes from 1.5kW to 22kW (3~ 380V...480V) with an integrated line filter and from 30kW to 132kW (3~ 380V...480V) with
optional external line filter. The overload capacity of these devices is 200% for 3.5 seconds and 150% for 60 seconds.
Device for quadratically increasing loads SK 700E-163-340-O-VT
:
In the performance range 160kW (3~ 380V...480V) a variant for quadratically increasing load is available. This load profile is
typical for fans and various pump applications. In contrast to the devices used for constant load torque, the overload capacity
here is limited to 125%.
NOTE
: The SK 700E with the performance range 30kW to 160kW varies in some technical details from the lower
performance devices. Details can be found in this manual.
This manual is based on the device software V3.3 Rev0 (P707) for the SK 700E. If the frequency inverter used has a different
version, this may lead to some differences. If necessary, you can download the current manual from the Internet
(http://www.nord.com/)

1.4 Safety and installation information
NORDAC SK 700E frequency inverters are equipment for use in industrial high voltage systems and are operated at voltages
that could lead to severe injuries or death if they are touched.
• Installation and other work may only be carried out by qualified electricians and when the device is
disconnected. The manual must always be available for these persons and must be complied with.
• Local regulations for the installation of electrical equipment as well as for accident prevention must be
complied with.
• The equipment continues to carry hazardous voltages for up to 5 minutes
after being switched off at the
mains. The equipment may only be opened or the cover or control element removed 5 minutes after the
equipment has been disconnected from the power supply. All covers must be put back in place
before the line
voltage is switched back on again.
• Even during motor standstill (e.g. caused by a release block, blocked drive or output terminal short circuit), the
line connection terminals, motor terminals and braking resistor terminals may still conduct hazardous voltages.
A motor standstill is not
identical to galvanic isolation from the mains.
• Attention, even parts of the control card and, in particular, the connection plug for the removable technology
units can conduct hazardous voltages. The control terminals are mains voltage free.
• Warning, under certain settings the frequency inverter can start automatically after the mains are switched on.
• The circuit boards contain highly-sensitive MOS semiconductor components that are particularly sensitive to
static electricity. Avoid touching circuit tracks and components with the hand or metallic objects. Only the
terminal strip screws may be touched with insulated screwdrivers when connecting the cables.
• The frequency inverter is only intended for permanent connection and may not be operated without effective
earthing connections that comply with local regulations for large leak currents (> 3.5mA). VDE 0160 requires
the installation of a second earthing conductor or an earthing conductor cross-section of at least 10 mm
2
.
• Normal FI-circuit breakers are not suitable as the sole protection in three-phase frequency inverters when
local regulations do not permit a possible DC proportion in the fault current. The standard FI circuit breaker
must comply with the new design as per VDE 0664.
• The inverter must be mounted in a switch cabinet that is suitable for its immediate surroundings. In particular it
must be protected from excess humidity, corrosive gases and dirt.
• In normal use, NORDAC SK 700E frequency inverters are maintenance free. The cooling surfaces must be
regularly cleaned with compressed air if the ambient air is dusty.
ATTENTION! DANGER TO LIFE!
The power unit can continue to carry voltages for up to 5 minutes after being switched off at the mains.
Inverter terminals, motor cables and motor terminals may carry voltage!
Touching open or free terminals, cables and equipment components can lead to severe injury or death!

2 Assembly and installation
2.1 Installation
NORDAC SK 700E frequency inverters are available in various sizes depending on the output. When installed in a control
cabinet, the size, power dissipation and perm. ambient temperature must be taken into account to prevent device failures.
The equipment requires sufficient ventilation to protect against overheating. Reference values apply here for the spaces above
and below the frequency inverter within the control cabinet.
(up to and inc. 22kW, above > 100mm, below > 100mm and from and inc. 30kW above > 200mm, below > 200mm)
Electrical components (e.g. cable ducts, contactors, etc.) can be located within these limits. There is a height-dependent
minimum separation distance from the frequency inverter for these components. This distance must be a minimum 2/3 of the
object height. (Example: cable duct 60mm high Æ2/3⋅ 60mm = 40mm gap)
Additional side gaps for devices up to and inc. 55kW are not required. Mounting can be immediately next to each other. The
installation position is normally vertical
. It must be ensured that the cooling ribs on the rear of the device are covered with a flat
surface to provide good convection.
Warm air must be vented above the device!
If several inverters are arranged above each other, ensure that the upper air entry temperature limit is not exceeded. (See also
Chapter 7, Technical data). If this is the case, it is recommended that an "obstacle" (e.g. a cable duct) is mounted between the
inverters so that the direct air flow (rising warm air) is impeded.

2.5 Line choke (accessories)
To reduce input side current harmonics, additional inductivity
can be installed into the line supply to the inverter.
These chokes are specified for a maximum supply voltage of
480V at 50/60 Hz.
The protection class of the chokes is IP00 and they must
therefore be installed in a control cabinet.
For frequency inverters with an output of 45 kW or more, a
line choke is recommended where several devices are being
used, in order to avoid possible adverse effects of one device
on another. In addition, the charging currents (mains voltage
fluctuations) are significantly reduced.

2.6 Output choke (accessories)
To reduce interference signals from the motor cable or to
compensate for cable capacitance in long motor cables, an
additional output choke can be installed into the inverter
output.
Take care during installation that the pulse frequency of the
frequency inverter is set to 3-6kHz (P504 = 3-6).
These chokes are specified for a maximum supply voltage of
460V at 0-100 Hz.
An output choke should be fitted for cable lengths over
150m/50m (unshielded/shielded). Further details can be found
in Chapter 2.10.4 "Motor cable".
The protection class of the chokes is IP00 and they must
therefore be installed in a control cabinet.

2.7 UB brake resistors (accessory)
During dynamic braking (frequency reduction) of a three phase motor, electrical energy is returned to the frequency inverter. In
order to avoid overcurrent cut-off of the frequency inverter, the integrated brake chopper can convert the returned energy into
heat by connecting an external brake resistor.
For inverter outputs up to 7.5 kW, a standard substructure resistor can be fitted;
it can also be optionally equipped with a heat monitor for additional
thermal protection of the resistor.
This design is no longer possible with higher frequency
inverter outputs. Instead, the chassis brake
resistors (Chapter 2.8) can be used.

2.8 Chassis brake resistors (accessory)
During dynamic braking (frequency reduction) of a three phase motor, electrical energy is released and returned to the
frequency inverter. To prevent a safety shut-down of the frequency inverter, the integrated brake
chopper can be activated by the connection of an external brake resistor.
The returned energy is converted into heat, so avoiding a possible overvoltage.
All chassis resistors are UL certified and are not subject to
restrictions in the North American market.
Connection is with screw connectors that are designated +B, B (1.5-22kW) or BR, +ZW (30-160kW), and the safety leads.
For overload protection, a thermal switch is located close to
a brake resistor. The switch is freely available via the
screw connectors (2 x 4mm

2.9 Wiring guidelines
The frequency inverter has been developed for use in an industrial environment. In this environment, high levels of
electromagnetic interference can influence the frequency inverter. In general, correct installation ensures safe and problem-free
operation. To meet the limit values of the EMC directives , the following instructions should be complied with.
(1) Ensure that all equipment in the cabinet is securely earthed using short earthing cables that have large cross-sections and
which are connected to a common earthing point or earthing bar. It is especially important that every control device
connected to the frequency inverters (e.g. an automation device) is connected, using a short cable with large cross-section,
to the same earthing point as the inverter itself. Flat conductors (e.g. metal clamps are preferable, as they have a lower
impedance at high frequencies.
The PE lead of the motor controlled by the frequency inverter must be connected as directly as possible to the earth
connection of the cooling element, together with the PE of the corresponding frequency inverter mains supply. The presence
of a central earthing bar in the control cabinet and the grouping together of all PE conductors to this bar normally ensures
safe operation. (See also Chapter 8.3/8.4 EMC guidelines)
(2) Where possible, shielded cables should be used for control loops. 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.
The shields of analog setpoint cables should only be earthed on one side on the frequency inverter.
(3) 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.
(4) Ensure that the contactors in the cabinet are interference protected, either by RC circuits in the case of AC contactors or by
free-wheeling diodes for DC contactors, for which the interference traps must b e positioned on the contactor coils.
Varistors for over-voltage limitation are also effective. This interference suppression is particularly important when the
contactors are controlled by the relay in the frequency inverter.
(5) Shielded or protected cables should be used for load connections and the shielding/protection should be earthed at both
ends, if possible directly to the frequency inverter PE/shield angle.
(6) If the drive is to be used in an area sensitive to electromagnetic interference, then the use of noise suppression filters is
recommended to limit the cable-dependent and radiated interference from the inverter. In this case, the filter must be
mounted as closely as possible to the frequency inverter and fully earthed.
It is also an advantage if the inverter is installed together with the line filter in an EMC-pr oof enclosure, with EMC-compliant
cabling. (See also Chapter 8.3/8.4 EMC)
(7) Select the lowest possible switching frequency. This will reduce the intensity of the electromagnetic interference produced by
the frequency inverter.
The safety regulations must be complied with under all circumstances when installing the
frequency inverter!
Note
The control cables, line cables and motor cables must be laid separately. In no case should they be laid in
the same protective pipes/installation ducts.
The test equipment for high voltage insulations must not be used on cables that are connected to the
frequency inverter.

2.10 Electrical connections
2.10.1 Line and motor connections
WARNING
THESE DEVICES MUST BE EARTHED.
Safe operation of the devices presupposes that qualified personnel mount and operate it in compliance with
the instructions provided in these operating instructions.
In particular, the general and regional mounting and safety regulations for work on high voltage systems
(e.g. VDE) must be complied with as must the regulations concerning professional use of tools and the use
of personal protection equipment.
Dangerous voltages can be present at the line input and the motor connection terminals even when the
inverter is switched off. Always use insulated screwdrivers on these terminal fields.
Ensure that the input voltage source is not live before setting up or changing connections to the unit.
Make sure that the inverter and motor have the correct supply voltage set.
Note: If synchronising devices are connected or several motors are switched in parallel, the frequency inverter must be
operated with linear voltage/frequency characteristic curves, P211 = 0 and P212 = 0.
The line, motor, brake resistor and control connections are located on the base of the device. To gain access to the terminals,
the device covers (cover and grid) must be removed. The connection terminals are now accessible from the front. All covers
must be put back in place before switching on the supply voltage!
In general, the line, motor and brake resistor cables are connected first as their terminals are located on the bottom circuit
board. The cable inlet is a slit opening on the base of the device.
Note: when using specific wiring sleeves, the maximum connection cross-section can be reduced.
Pay attention to the following:
1. Ensure that the voltage source provides the correct voltage and is suitable for the current required (see Chapter 7
Technical data). Ensure that suitable circuit breakers with the nominal current range are inserted between the voltage
source and the inverter.
2. Connect the line voltage directly to the line terminals L
1
- L2 - L3 and the earth (PE).
3. A four-core cable must be used to connect the motor. The cable must be connected to the motor terminals U - V - W and
the PE.
4. If shielded cables are used, then the cable shield can also be applied to as much surface as possible on the shield support
angle.
Note
: The use of shielded cables is essential in order to maintain the specified radio interference suppression level. (See
also Chapter 8.4 EMC limit value classes)
