Installation put in service
This chapter includes a checklist with steps that should be taken before the coupling NX series is switched on
and put into operation.
3.1.
Safety instructions for installation and initial installation
National regulations in installation and operation of electrical equipment must be respected.
WARNING The coupling NX series test system is not suitable for use in an explosive
atmosphere.
WARNING Connect the EUT only after the initial system setup has finished.
3.1.1.
Qualifications of the staff
Basic knowledge of electrical engineering and electromagnetic compatibility is required to service the unit. The
national regulations for installation of electrical equipment as well as the safety at work of electrical equipment
must be known to the user.
3.1.2.
Installation
The coupling NX series 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!
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.
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.
The equipment works, on principle, with two independent power supplies, one for the generator and one for the
EUT. The coupling NX series 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.
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 organizations 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.

Manual of operation V 1.03 11 / 53
3.2.2.
Grounding and power connection
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. To avoid
electric shock, the power cord protective grounding conductor must be connected to ground.
System GND
The system is connected to GND via the earth wire of the connected mains power cable for the coupling,
generator and the EUT supply. A separate GND wire from the reference GND plane to the building earth point
may be useful to avoid interferences to other areas.
EUT GND
Ensure that a reliable return path for the interference current is provided between the EUT and the generator.
The GND wire from the generator to the reference GND and must be designed as a low inductance connection
suitable for high frequencies. The reference ground plane and the ground connections to the instruments, as
described in the relevant test standards, serve this purpose well.
Protection (optional)
A proposal is to separate protection of the EMC system with filters, insulation transformer or fault current
protection and other measures may be useful for the EMC installation. The advantage is the separation of the
EMC system from all other installation.
A shielded room with adequate filters may be the best solution for avoid unwanted conducted and radiated
interference to other areas.

Connecting System coupling NX with compact NX5 generator
When setting up the test national and international regulations regarding human safety have to be guaranteed.
All units, the surge generator, the EFT and the coupling matrix can be installed one
above the other. The coupling matrix should be used as central output for the EUT
and should be mounted directly onto the ground reference plane.
The compact NX5 has to be mounted directly above the coupling NX5 due to the short
HV cable. It is recommended to connect the simulator to the ground reference plane
of the test set-up.

General
The coupling network has to couple the transients well defined to the lines of a power supply system. The coupling is
realized by discrete coupling capacitors, having a sufficient voltage capability and bandwidth. The specification is
given in IEC 61000-4-4, IEC 61000-4-5.
The coupling/decoupling network is divided in two parts:
- The decoupling and filtering unit
- The coupling unit
The decoupling unit has to
- To decouple the low impedance power mains supply from the test setup.
- protect other equipment which is connected to the power mains supply
But which is not part of the test set-up.
The coupling network superimposes the transients to the lines of a power supply system, AC as well as DC supply.
6.1.
Coupling modes
The test can be conducted with different coupling modes.
61000-4-5 Surge immunity requirements
- Line or lines to protective earth (unsymmetrical) e.g. L1-PE; L1+L2+L3+N-PE
- Line to Line (symmetrical) e.g. L1-L2 or L3-N
61000-4-4 Electrical fast transients
Coupling mode line, or lines to reference ground. All combinations are possible. The protective earth (PE) is
regarded as equal to all other lines and therefore is tested as all other lines
6.2.
Coupling to Signal Lines
The coupling to I/O lines is realized with other coupling
networks than used for power supply lines. The loading of
the I/O lines with large coupling capacitors is mostly not
possible. The data transmission may be disturbed
For coupling to I/O lines special couplers acc. to IEC
61000-4-5 are available, such as the DCD series and
previous CNV 504 and the CNV 508 family for eight wire
systems.
For coupling the Burst transient to signal lines, a
capacitive coupling clamp is used. The clamp is
connected and controlled via the coupling NX. Normally it
is connected directly to the coaxial output of the generator
itself.

6.3.
Surge coupling decoupling networks rated up to 200 A
The voltage drop across the CDN shall not exceed 10 % of the CDN input voltage at the specified current rating,
but should not exceed 1.5 mH.
To prevent unwanted voltage drops in the CDN, the value of the decoupling inductors are reduced for CDNs
rated at > 16 A. As a consequence, the peak voltage and the duration of the open-circuit voltage waveform which
is measured with no load can vary within the tolerances given in Tables 4, 5 and 6 in IEC 61000-4-5: Ed 3. High
current EUTs represent lower impedances and cause surges close to short-circuit conditions. Therefore, for high
current CDNs it is the current waveform which is predominant. Large tolerances on the voltage definition are
acceptable.

Data correspond to Table 4 IEC 61000-4-5 Ed3
The selection of the CDN specification from Table 4 IEC 61000-4-5 Ed3 shall be made to match the current rating
of the EUT (for example: an EUT rated at 7 A shall be tested using a CDN complying with the specifications of a
16 A rated CDN). Any higher current rated CDN can be used if it meets the specification requirements in Table 4
for the relevant lower current rating of the EUT (for example: a CDN rated 63 A can be used for testing an EUT
rated at 5 A, if it meets the specification requirements of a 16 A rated CDN).

Categories for DC application
The IEC 60947-4-1 rating system is broken down into different utilization categories that define the value of the
current that the contactor must make, maintain, and break.
DC-1
Non inductive or slightly inductive loads, resistance furnaces, heaters
DC-3
Shunt motors, starting and breaking of a shunt motor during inching or plugging. The time constant
shall be less than or equal to 2 msec. On de-energization, the contactor will break around 2.5 times the
starting current at a voltage that may be higher than the line voltage.
DC-5
Series-motors, starting and breaking of a series motor during inching or plugging. The time constant
being less than or equal to 7.5 msec. On energization, the contactor sees about 2.5 times the nominal
full load current. On de-energization, the contactor breaks the same amount of current at a voltage
which can be equal to the line voltage.
This list is not complete. For more information refer to specific manuals of the contactor manufacturers.

Operation
8.1.
Power supply input (EUT)
The power supply input for the EUT is located at the rear side of the coupler. Adapters for customized three phase
connectors have to be realized by the user himself or can be manufactured on customer’s specification.
The output of the power mains supply (surged lines) for the EUT is located at the front panel of the equipment.
8.2.
Synchronization
The synchronization signal for trigger the Surge and optional Burst impulse is generated in the three phase coupler.
The NX generator receive the sync signal from the coupling NX via the sys.link cable.
The synchronization signal is taken from the coupler internal lines L1 - N. Alternative the phase synchronization can
be connected to the SYNC IN plugs at the rear side of the compact NX generator.
Phase synchronization angle in star-delta 3-phase system
The synchronization in a 3-phase coupler system is taken between L1 – N lines.
In case of a delta supply without connected neutral line, an artificial high impedance
network defines the neutral point. This artificial neutral is taken for the phase
synchronization.
For all couplings the generator calculates the correct phase angle for phase
triggering.
The tables below shows the correction angels considering the phase in a 3-phase
system with synchronization signal from L1-N lines. The generator firmware will
automatically add the correction angle to the settled value.

Operation with coupling NX or generator internal CDN
The coupling network of the coupling NX is operated and controlled via the compact NX generator. After power on,
the compact NX generator scans the system for searching all devices.

The test generator realizes that a three phase coupler is connected and shows the possible coupling modes in the
display of the generator. The complete system is controlled by the generator from front panel or software.
If the external coupling network is connected or switched on later than the generator, the generator must be reset by
switching power ON/OFF.
On the front panel of the coupler the user can switch ON/OFF the power supply of the EUT.
Using iec.control software the coupling matrix is completely controlled by software.
Coupling device detection
After power ON the compact NX, the controller searches all external devices.

As DC input the terminals L1 and N must be used. These two plugs are marked at the rear side of with an
additional plus or minus sign.
TEST ON Switch
There are special models for DC current where the coupling network should have the same parameters for AC
and DC. A special DC mains switch is installed, for meet the DC specifications. This costly expansion requires a
larger enclosure than the normal version.
Models with no special DC input have a reduced DC current capacity. The switching capacity of conventional
AC contactors for DC application is limited. Therefore, the specification for DC current and voltage are reduced
compared to the AC specifications as shown in the technical data.

Maintenance and calibration
10.1.
General
The coupling network is absolutely maintenance-free by using.
10.2.
Calibration and Verification
10.2.1.
Factory calibration
Every EM TEST generator is entirely checked and calibrated as per international standard regulations before
delivery. A calibration certificate is issued and delivered along with a list of the equipment used for the calibration
proving the traceability of the measuring equipment. All auxiliary equipment and accessories are checked to our
internal manufacturer guidelines.
The calibration certificate and the certificate of compliance (if available) show the date of calibration.
The EM Test equipment are calibrated in the factory and marked with a calibration
mark. The used measuring instruments are traceable to the Swiss Federal Office of
Metrology.
The calibration date is marked. The validity of the calibration is to the responsibility
of the user’s quality system. Neither the certificate of calibration nor the
corresponding label mark any due date for re-calibration.
Example: Calibration mark
10.2.2.
Guideline to determine the calibration period of EM Test instrumentation
Our International Service Departments and our QA Manager are frequently asked about the calibration interval of
EM TEST equipment.
EM TEST doesn’t know each customer’s Quality Assurance Policy nor do we know how often the equipment is
used and what kind of tests is performed during the life cycle of test equipment. Only the customer knows all the
details and therefore the customer needs to specify the calibration interval for his test equipment.
In reply to all these questions we like to approach this issue as follows:
EM TEST make use of a solid state semiconductor switch technique to generate high voltage transients. A
precious advantage of this technique is the absolute lack of periodical maintenance effort. In consequence
thereof a useful calibration period has to be defined based on two criteria:
- The first one is the customer’s Quality Assurance Policy. Any existent internal regulation has to be applied at
highest priority. In the absence of such internal regulation the utilization rate of the test equipment has to be
taken into consideration.
- Based on the experience and observation collected over the years EM TEST recommends a calibration
interval of 1 year for frequently used equipment. A 2-years calibration interval is considered sufficient for
rarely used test generators in order to assure proper performance and compliance to the standard
specifications.
10.2.3.
Calibration of Accessories made by passive components only:
Passive components do not change their technical specification during storage. Consequently, the measured
values and the plots stay valid throughout the storage time. The date of shipment shall be considered as the date
of calibration.
10.2.4.
Periodically In-house verification
Please refer to the corresponding standard before carrying out a calibration or verification. The standard
describes the procedure, the tolerances and the necessary auxiliary means. Suitable calibration adapters are
needed. To compare the verification results, EM Test suggests referring to the wave shape and values of the
original calibration certificate.
All calibrations and verifications are always done without mains supply voltage connected to the coupling network
input.
Danger
Before starting the calibration or verification
remove the EUT Mains Supply
from the generator and from the coupling network

Inrush current
The inrush current depends from the mains impedance, the inductance of the surge inductors and the EUT
impedance. The inrush current in the tables below are theoretical maximum, calculated with the decoupling
inductance only. These values cannot be reached in a real system.

100 A Plugs and connectors from Multi Contact
Safety sockets KBT6AR-N/...-S with snap-in lock and crimp connection
Model KBT6AR-N/...-S safety sockets are sockets with locking devices and for
crimping onto highly flexible Cu conductor with cross-sections of 10mm2, 16mm2
or 25mm2.
This safety socket is suitable for mating with either safety flush-mouting plugs or
plugs model KST6AR-N. Used together with a flush-mounting plug it acts as an
appliance connector and with plugs as a coupler.
Sockets BP...AR-N with snap-in lock and crimp termination
Crimp termination for flexible and highly flexible Cu-cables class 6 (according to
IEC 6028). MC recommends a hexagonal crimp. Indent crimping and soldering is
also possible. Cables with compacted conductors need a special crimping sleeve.
Safety branch adapter AZB6AR-N-S/6-4
Safety branch adapter with snap-in lock and ergonomic PA/TPE insulation that
grips well. Mating plugs with suitable locking devices can be snap-locked into the
socket. With one pick-off socket Ø 6mm and two safety sockets Ø 4mm for
voltage tests up to 600V, CATIII.
Safety flush-mounting plugs ID/S6AR-N-B4S with snap-in lock and threaded stud
Model ID/S6AR-N-B4S safety flush-mounting plugs are insulated plugs designed
for flush mounting in housings and panels. The plugs are designed to mate with
sockets KBT6AR-N. The resulting plug connections are securable by means of
snap-in lock. The plug ID/S6AR-N-B4S also mates with Ø 4mm MC Safety plugs,
because the Ø 6mm plug has a Ø 4mm socket hole. The internal connection is
made with an M6 threaded stud with nuts and washers. These safety flushmounting plugs are also used to be connected with test leads according to the test
accessories IEC/EN61010, (UL3111) and are UL recognized.

Introduction ...10BV...
Single-pole round connectors, insulated, Ø 10mm with bayonet locking
The MC Connectors may be used as “connectors for class II equipment”. The
connector itself meets the requirements of double and/or reinforced insulation.
Important note:
The new round connector Ø 10mm fulfils and surpasses the safety requirements
for encapsulated plug connectors – protection against electric shock according to
IEC 61984.

Couplers
Sockets with bayonet locking and AxiClamp termination for
flexible cables class 5 and 6 KBT10BV-AX/M...-C...
What is AxiClamp?
The patented lead termination system for electrical and mechanical termination of
Cu leads 6mm² – 300mm² class 5 and class 6 according to DIN VDE 0295, IEC
60228.
The individual strands of the connecting lead are screw-clamped against a metal
cone by means of a tapered threaded sleeve. The metal cone is part of the
contact body. This gives a firm clamp termination with an equally good transition
resistances compared to a crimp termination and additional advantages besides.
Bayonet locking system (BV-System)
Plugging procedure:
The markings on the plug and socket have to be lined up. Insert plug in with socket to the stop then insert further
with axial pressure and turn simultaneously to the right (seen from the plug in the direction of insertion) until the
bayonet lock engages.
Unplugging procedure:
Push plug in further and turn simultaneously 1) to left (seen from the plug in the direction of insertion) until the
markings are lined up. Pull plug out of socket.
Caution:
During connecting or disconnecting, the 10BV... and 16BV... connectors must be at no load, the 30BV...
connectors must be isolated from the power supply. Protection against electric shock has to be provided in the
end-use product.

Multi Contact MC Locking system (AR-system)
The MC Locking system (AR) operates on the “push-pull” principle. It is self – locking when connected.
Disconnection is effected by an axially displaceable coupling ring: first push, then pull to disconnect. Dirty parts
should be cleaned with industrial alcohol before connecting.
