2 INTRODUCTION
2.1 General description
The NSG 3150 with the CDN 3153-S63.1 test systems are designed primarily for cable-borne
transient interference tests as specified in the European generic standard IEC/EN 61000-6-1
covering equipment for household, office and light industrial use, and IEC/EN 61000-6-2 for
applications in industrial environments, in accordance with the requirements of the basic
standard. IEC/EN 61000-4-5.
The EU directive no. 2014/30/EU (for the assignment of the CE symbol) refers to this
standard for this type of equipment.
The CDN 3153-S63.1 is modular and automated coupling/decoupling network for inject surge
pulses to 3-phase AC supply lines up to 3 x 690 V /63 A. With the option INA 3151-63 it is
possible to test with DC supply up to 1000 V / 63 A
The CDN 3153-S63.1, connected to the NSG 3150 can handle the IEC 61000-4-5
recommendations. This standard requires that the EUT power voltage level has to be taken
into account.
2.1.1 Reference ground connector
CDN 3153-S63.1 is part of the 3000-series family 3-phase coupling networks, rated to test
equipment of 63 A per phase. It can couple combination wave up to 15 kV.
No PQT test can be selected since the three phase PQT test recommends other test units
like the Teseq Profline 2100 system.

3 SAFETY INSTRUCTIONS
WARNING - Improper or careless operation can be fatal! The instrument
must only be accessible to trained persons.
The coupling networks CDN 3153-S63.1 are intended for use with surge generators. These
generators produce high voltage test pulses with high energy.
These operating instructions form an essential part of the equipment and must be available to
the operator at all times. The user must obey all safety instructions and warnings.
Neither Teseq AG, Reinach, Switzerland, nor any of its subsidiary sales organizations can
accept any liability for personal, material or consequential injury, loss or damage that may
result from improper use of equipment and accessories.
3.1 General
Use of the coupling device in combination with the generator is restricted to authorized and
trained specialists.
The user is directly responsible for ensuring that the test rig does not cause excessive
radiated interference which could affect other instrumentation. The test system itself does not
produce any excessive EM radiation. However, the injection of interference pulses into a EUT
can result in it and/or its associated cables radiating electromagnetic energy.
To avoid unwanted radiation, the standards organizations recommend that the test setup be
operated inside a Faraday cage.
WARNING - Because of its construction, the instrument is not suitable for
use in an explosive atmosphere.
WARNING - Persons fitted with a heart pacemaker must neither operate
the instrument nor approach the test setup while a test is being executed.
Only approved accessories, connectors, adapters, etc. are to be used to ensure safe
operation.
Upon switching on the generator, it will perform a self test. Therefore, the
EUT output is to be considered as carrying EUT power all the times!
WARNING –For lift the device suitable lifting device is required.

7
The test rig must provide adequate insulation protection for up to 15 kV surge and the
additional rated EUT mains voltage (peak). Particular care should be given to the
connections between the CDN and the equipment under test (EUT).
The rated data for the cable insulation must be such that the insulation of the cables in the
high-voltage circuit is 20 kV, and the power cable to the device is min. 2.5 kV.
The EUT may only be tested when placed inside a suitable protective enclosure which should
provide protection against flying fragments, fire and electric shock.
Under normal operating conditions no toxic gases are released.
The pulse voltage must not be able to find its way to unearthed metal objects in the event of
the EUT failing.
Only use the instrument in a dry room.
Never leave the instrument unattended when the EUT is switched on.
Do not open the instrument. Repairs and adjustments must only be carried out by qualified
maintenance personnel.
Do not continue to use the CDN in case of mechanical damage. The CDN housing and the
cables have both insulating and a screening function, which can only be assured while the
housing is intact. Return the damaged CDN to a Teseq service center immediately for repair.
Warning symbols on the test system:
CAUTION! Warning of a danger spot (refer to the documentation).
CAUTION! Warning of electrical hazards!

8
4 INSTALLATION
Test system conforms to protection class 1. Local installation regulations must be respected
to ensure the safe flow of leakage currents.
WARNING - Operation without an earth connection is forbidden!
WARNING - Switch off EUT power before accessing EUT power IN or OUT
terminals.
The terminals of the three phases CDN 3153-S63.1 are accessible with the
included insulated Allen key.
An external fuse is required with max. 63 A current rating. There are no
built in fuses in the CDN 3153-S63.1.
Two independent ground connections are necessary - one for the test system and one for the
EUT. These must be connected back to the local permanent installation or to a fixed,
permanent ground conductor.
Operate the equipment only in dry surroundings. Any condensation that occurs must be
allowed to evaporate before putting the equipment into operation. Do not exceed the
permissible ambient temperature or humidity levels. Use only officially approved connectors
and accessory items. Take care to have access to all connectors for disconnect them in no
time in case of emergency.
Ensure that a reliable return path for the interference current is provided between the EUT
and the generator. The ground reference plane and the ground connections to the
instruments, as described in the relevant test standards, serve this purpose well.
Since the instrument works, on principle, with two independent power supplies (one for the
coupling network and one for the EUT), the CDN 3163-S62 must be disconnected from both
sources before any modifications to the test rig are undertaken. Besides the mains
connections themselves, certain components also operate at high voltages, which are not
provided with any form of extra protection against being accidentally touched.

9
4.1 Installation of a power emergency off switch
The CDN itself has an internal power switch to control EUT power ON/OFF, accessible via
the user interface or the software, but nerveless, it is recommended to connect the EUT
power through a properly rated circuit breaker and an emergency off button as per IEC/EN
61010-1. In order to ensure an easy and quick access, the button should be located close to
the test setup and should be clearly and visibly labelled as a device for “Emergency power
ON/OFF”switching.
WARNING - The test setup should only be accessible to trained persons.
Dimensioning of the mains supply and rating of fuse protection of the AC power supply must
conform with local electrical codes and EUT requirements.
Inappropriate arrangement, mounting, cabling or handling of the device under test or the
protective elements can make the protective features that are incorporated in the design of
the instrument worthless.

10
5 APPLICABLE THE SAFETY STANDARDS
The construction of the instrument conforms to the safety requirements and offers everything
necessary for safe and efficient operation.
Development and manufacture is in compliance with ISO 9001. The system complies with the
safety requirements of IEC/EN 61010-1 (safety requirements for electrical equipment for
measurement, control and laboratory use).
All mains power driven types of units are designed for high voltage working safety.
The interference immunity has been tested in accordance with EN 61326-1. It is the user’s
responsibility to ensure that the test rig does not emit excessive electromagnetic interference
(EMI) which might affect other items of equipment.
The test system itself does not produce any excessive radiation; however, the injection of
interference pulses into the EUT can result in the device and/or its associated cables starting
to radiate EMI. To avoid radiating of unwanted interference the test rig might be operated in a
Faraday cage.
Since the purpose of the test system is to produce interference signals for interference
immunity testing, the requirements in IEC/EN 61000-6-x series concerning limiting the
radiated EMI can only be complied with by operating the test system inside a Faraday cage.
5.1 Test execution
WARNING - The test area must be organized so that unauthorized
persons do not have access during the execution of a test. If a safety
contact (Interlock) is used as a means of access control to the test zone
(e.g. a Faraday cage), then an additional contact connected in series is
necessary to provide protection for parts of the EUT that are likely to be
touched accidentally.
During a test, the EUT together with its accessories and cables are to be
considered live at all times. The test system must be stopped and the
EUT supply disconnected before any work can be carried out on the
EUT. This can be achieved simply by opening the interlock circuit.
The EUT is to be tested only in a protective cage or under a hood which
provides protection against electric shock and all manner of other
dangers pertaining to the particular EUT (see: User warnings -
Generator).
The user must observe safety instruction for all the instruments and
associated equipment involved in the test setup.
Test setup configuration is to be strictly in compliance with the
methods described in the relevant standard to ensure that the test is
executed in a compliant manner.

11
6 PULSE COUPLING
6.1 Combination wave test
The surge test in compliance with IEC/EN 61000-4-5 simulates high voltage/high energy
interference as experienced with a lightning strike. Generally speaking, the interference finds
its way into equipment by way of the mains supply.
This kind of interference can affect equipment in either of two ways. Firstly, the interference
can be coupled directly into the equipment via the mains supply. The interference is
conveyed directly from the source (e.g. lightning strike to external power cables). Every item
of equipment connected to this power source will be affected by the interference pulses.
Surge pulse interference can also occur on signal and data lines through coupling effects and
electrical discharges. For this, the CDN 117/118 is recommended.
The test system enables tests to be carried out using both coupling methods. The EUT is
connected to the mains power socket on the front panel of the test system for the direct
mains injection test. Externally coupled tests require the interference to be superimposed on
the EUT power feed cable via an external coupling unit that is connected to the Surge output
on the front panel of the system.
6.1.1 Combination wave (CW) - Surge generator
The combination wave test involves the generation of high voltage surge pulses as specified
in the international standard IEC/EN 61000-4-5.
The test pulses are injected directly into the EUT power supply lines. The EUT obtains its
power from the EUT power outlet on the CDN of the test system where the voltage has the
interference signal superimposed on it.
▪
Surge voltage of up to 15 kV which follows the 1.2/50 μs curve (open circuit)
▪
Surge current of up to 7.5 kA which follows the 8/20 μs curve (short circuit).

9.1.2 Ground reference terminal
A good earth connection between the CDN and the earth reference plate is essential. This
terminal of the CDN provides a solid earth connection point to the test system. There is no
need to connect the earth connector from the generator itself, since the surge connectors
provide the reference ground from the generator to the CDN.
9.1.3 Surge input sockets
These sockets (High, Low) serve to connect the surge signal from the generator to the CDN.
The surge output from the generator is potential free (floating). The inner conductor of each
connector is the surge high and surge low connection respectively while the outer conductor
(shielded) is connected to the instruments earth.

9.2 Rear panel CDN 3153-S63.1
9.2.1 Mains input and power switch
The main input is the power to the internal electronics of the CDN.
This connection must not be confused with the EUT power input.
The input contains the mains power input connector, the mains switch and the mains fuses.
Before putting the instrument into operation, please make sure that the
voltage range shown on the mains input module corresponds with the
voltage of the local supply to which the instrument will be connected, and
whether the fuses are correctly rated (2 x 3.15 AT).
The used cable must be rated for a current of at least 3.5 A

17
9.2.2 EUT input supply
The power source connected to this connector provides the power for the
EUT.
Surge interference signals are coupled into this supply line internally.
Special care must be taken to use the right phase line from the EUT input at
the EUT output connector.
Depending on countries, different color codes are used. Please refer to the
EUT input section in this manual to verify the coding.
Because of the capacitors in the internal coupler, earth leakage currents of
up to several amperes can occur in the EUT power supply network.
The test system must therefore be correctly earthed and be powered from a
supply that is not protected by a residual current detector (RCD).
EUT with DC supply must be powered by using the INA 3151-63 1000 VDC breaker. Take
care to the correct connection for match the polarity with the EUT.

9.2.4 Color codes of a 3-phase system
Conductors of a three phase-system are usually identified by a color code, to allow for
balanced loading and to assure the correct phase rotation. Colors used may adhere to
International Standard IEC 60446, older standards, or to no standard at all, and may vary
even within a single installation. For example, in the U.S. and Canada, different color codes
are used for grounded (earthed) and ungrounded systems.

Peak impulse voltages of up to 2250 V can occur on these power lines. Such voltages can,
under certain circumstances, destroy AC/DC power supplies. It is the user’s responsibility to
ensure adequate protection being provided at the inputs of the source.

9.3 Phase rotation indication
This important and easy to read feature guaranties a correct coupling especially in
synchronous mode.
The phase rotation identifies cation at the back off the CDN units shows clearly, if all phases
are connected and if the rotation of L1, L2 and L3 are correctly set, this is important
especially in synchronous mode. The phase angle shift of 120° is a function of the actual
rotational angle, following a definite order. For clockwise rotation the phase sequence order
is 1-2-3.
However, if we reverse the rotation winding 2’s waveform will be leading 120° ahead of 1
instead of lagging, so the coupling point of a synchronous coupling will be wrong, since the
zero crossing of L1 is measured and calculated for the other lines. The counter clockwise
rotation phase sequence is 2-1-3, which is wrong.
To test the proper phase rotation of the EUT
Power Input, push the button “Test” beside the
LED’s - phase rotation will be shown by the
LED’s as long as the button is pushed.

20
This is a correct EUT power setting, all phases are connected (all lines indication are on) and
the rotation is right too.
The EUT power lines provide all power, but the phase rotation is wrong. In this case the
exchange of line L1, L2, or L3 will solve the rotation problem.
Not all EUT power lines provide power and the phase rotation is wrong too. All phase of the
EUT in power need to be checked and re-plugged.
