power input.
The following symbol draws your attention to a circumstance where non observation of the warning
could lead to component damage or danger to the operating personnel.
Example:
Never connect or disconnect the EUT while the test system is performing a test.
1.1 General description
The NSG 3150 test system enables cable-borne EMC (electromagnetic compatibility)
immunity tests to be carried out on electrical equipment intended for household, office, light
industrial or commercial use. The test system is a concept from Teseq AG for
electromagnetic immunity testing purposes and fulfills the requirements to accomplish CE
marking.
It is an open system, built on a modular principle that communicates through a serial and
standardized bus system and has open interfaces available. Operation is performed by
means of standardized operator interfaces.
A master controller in the NSG 3150 system architecture takes care of all the “real-time”
control functions and communicates with all the function modules both within the instrument’s
casing and external devices via an interbus link.
The system has a simple construction. All function units contain a slave controller. All these
units are connected together through their slave controllers and networked with the central
master controller via a field bus (Interbus). Information concerning the special features and
their adjustable parameters are stored directly in the function modules. In addition to this bus
system, the NSG 3150 system also has a further interface standard, Ethernet, with which the
system can be controlled via single PC, a computer network or even via the Internet.
This modularity enables the function units to be re-combined in ever newer instruments and
subsystems. The function units can be readily expanded to cope with new standards and
new function units for new parameters can be incorporated in existing systems.
To ensure optimal user and equipment safety, only industry-standard and correctly specified
plugs and sockets are used throughout. High voltage outputs are switch-protected.

2 STANDARDS AND APPLICATIONS
The NSG 3150 test system is designed to test lighting, communication and energy
distribution equipment, railways and protection systems and relays (e.g. IEC 60255-26). The
15kV surge pulse voltage 1.2/50 µs, 8/20 µs allows manufactures to reach new quality levels,
which helps them to outperform competitors.
2.1 Combination wave
The surge test, in compliance with IEC / EN 61000-4-5. Duplicates high voltage / high energy
interference as experienced with a lightning strike. Generally speaking, the interference finds
its way into equipment via the mains power 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.
Alternatively, the pulses from the source of the interference or its associated mains cables
can be coupled into other equipment positioned nearby.
Surge pulse interference can also occur on signal and data lines through coupling effects and
electrical discharges.
The 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 CDN for direct mains injection
tests. Externally coupled tests require the interference to be superimposed onto signal / data
line cables via an external coupling unit that is connected to the surge output on the front
panel of the CDN.

7
2.2 Pulsed magnetic fields (option)
Tests with pulsed magnetic fields, or PULSEM tests, simulate the type of interference
produced by surge pulses as a result of lightning strikes to buildings and other metallic
structures such as freestanding masts, ground conductors, grounding networks, etc. as
specified in IEC / EN 61000-4-9. Magnetic fields of this type can upset the operation of
installations that find themselves within such fields. The NSG 3150 performs this test by
causing a heavy current to flow in a magnetic field coil such that the amplitude of the pulse
current produces a proportional field within the coil parameters.
The magnetic field coils, available as accessories, are connected to the surge pulse output
socket via an INA 753 pulse shaping network.
With the NSG 3150 it is possible to create magnetic fields much higher than
required in the IEC / EN 61000-4-9 standard. It is in the scope of the user to
test only inside the Standard requirements

3 SAFETY INSTRUCTIONS
The NSG 3150 system and its accessories operate at high voltages.
WARNING - Improper or careless operation can be fatal!
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
The NSG 3150 must be operated only by authorized and trained specialists.
The generator is to be used only for the purpose specified by the manufacturer. The user is
directly responsible for ensuring that the test setup 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 radiation. To avoid
unwanted radiation, the standards organizations recommend that the test setup be operated
inside a Faraday cage.
WARNING - Because of its construction, the NSG 3150 is not suitable for
use in an explosive atmosphere.
WARNING - Personnel 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.
WARNING - Connect the EUT only after the initial system selftest has
finished.
- The safety is not guarantee when using the device in other application than specified.
- Under normal operating conditions no toxic gases are released.
- Take care to have access to all connectors for disconnect them in no time in case of
emergency.

9
3.2 Installation
The NSG 3150 test system conforms to protection class 1. Local installation regulations must
be respected to ensure the safe flow of leakage currents.
WARNING - Operation without a ground connection is forbidden!
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.
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.
The test system may only be opened by a qualified specialist upon specific instruction given
by the manufacturer. Since the instrument works, on principle, the NSG 3150 must be
disconnected from both sources before any modifications to the test setup are undertaken.
Besides the mains connections themselves, certain components also operate at high
voltages, and are not provided with any form of extra protection against accidental contact.
Take care to have access to all connectors for disconnect them in no time in case of
emergency.
3.3 Installation of an EUT power switch
The EUT input should be connected through a properly rated power switch device, which
should be located close to the test setup. In order to ensure easy and quick access to the
EUT power, the switch should be clearly and visibly labeled as “EUT power ON / OFF”.
The in-house power distribution must be equipped with a proper circuit breaker and an
emergency off button as per IEC 61010-1.
WARNING - Operation without a ground connection is forbidden!
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 EUT or ground can hamper or negate the effectiveness
of the NSG 3150’s safety features.

10
3.4 Applicable safety standards
The NSG 3150 conforms to the safety requirements and offers all the features 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).
It is the user’s responsibility to ensure that the test rig does not emit excessive
electromagnetic interference (EMI) that might affect other 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 radiating EMI. To avoid
radiating unwanted interference the standards organzations recommend that the test setup
be located in a Faraday cage. Since the purpose of the test system is to produce interference
signals for interference immunity testing, the requirements in the IEC / EN 61000 series
concerning limiting the radiated EMI can only be complied with by operating the test system
inside a Faraday cage.
3.5 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.
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
3.6 User Warnings Generator
WARNING - Users must be aware of the following dangers that can
occur during testing:
Local burning, arcing, ignition of explosive gases.
EUT supply current surge caused by a flashover or breakdown
resulting from the superimposed high voltage.
Disturbance of other, unrelated electronics, telecommunications,
navigational systems and heart pacemakers through unnoticed
radiation of high frequency energy.
In the test system the interference voltage, corresponding to the
level called for in the relevant test specification, is superimposed
also on the EUT’s protective earth conductor. Earth contacts or
pins (e.g. as in German and French mains plugs) as well as the
EUT earth itself can therefore be at an elevated voltage level that
would make touching dangerous. In many power connectors
even the screws are linked to the protective earth.
Warning symbols on the test system:
CAUTION! Warning of a danger spot (refer to the documentation).
CAUTION! Warning of electrical hazards!
CAUTION! Warning “Lift two men”!

12
3.7 Dangers concerning the EUT
WARNING - Users must be aware of the following dangers that can
occur during testing:
EUTs are often functional samples that have not yet been
subjected to safety tests. It is therefore possible that the EUT
could be damaged by internal overloads or may even start to
burn.
As soon as the EUT shows signs of being disrupted the test
should be stopped and the power to the EUT switched off.
Internal disruption of the electronics can result in the
interference voltage or the EUT supply voltage being present on
the EUT’s outer casing.
Electrical breakdown or arcing from connections that are
overstressed voltage wise during the test.
Explosion of components with fire or fragmentation as a result of
energy dissipated, e.g. from the resultant supply current or
ignition of vaporized plastic materials.
Faulty behavior by the EUT, e.g. a robot arm strikes out or a
temperature controller fails, etc.
The user is responsible to control the rating and the integrity of all
cables connected to the NSG 3150 generator, especially cables
connected to the Surge output.

5.1 Front panel
5.1.1 Reference ground connector
The earth connection between the CDN and the generator is realized via the shield of the HV
connectors. There is no need to connect the ground connector from the generator itself.
Without using a Teseq CDN, the NSG 3150 can be efficiently connected to the ground reference
plane using a ground strap connected to the reference ground connector point.
5.1.2 Surge output
These output (high, low) connects the surge output impulse to a 1-phase or 3-phase coupling unit or
to another external coupling unit.
These coaxial high voltage output are protected by a plexiglas window. The surge output 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 NSG 3150’s ground point.
Cable insulation for EUT surge output must be rated for 20 kV

5.2.3 Synchro-Bus system
This connection includes external device control and interlock capability. If the NSG is used only as a
stand alone unit, the termination connector needs to be plugged otherwise the unit will not start.
All connected accessories will be detected automatically. Written tests are linked with this accessories
so if other accessory is connected, it may get an error if the test contains not the suitable accessories.
Any automated CDN and complementary automated equipment need to be linked together. Thereby
the termination connector needs to be moved to the system output plug of the last unit of the system.
The interfaces for the interbus, interlock and synchro-bus are bundled together in a sub-miniature D-
connector. These three interfaces are looped through from one instrument to another.
NOTE - Good EMC engineering practices should be applied when connecting
signals to this port. As the whole system generates disturbances, in order to
avoid auto disturbing, all wires connected to this port should be properly
shielded, the shield of the cable should not serve as signal return path and the
shield should be connected via a large surface to the conductive shell of the
Sub-D plug.
