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 compact NX5 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.

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 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.

EUT Power supply and 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 61010-1:2001.
Dimensioning of the mains supply and rating of fuse protection of the AC or DC power supply must conform with
local electrical codes and EUT requirements. Inappropriate arrangement, mounting, cabling or handling of the
EUT or ground can reduce or negate the effectiveness of the compact NX5’s safety features.
3.4.1.
Notes on protective devices which need to install the operator
There are two different protective devices in a mains distribution system for safe operation.
A Fault current protection: A residual-current device (RCD), or residual-current circuit breaker (RCCB)
is an electrical wiring device that disconnects a circuit whenever it detects that
the electric current is not balanced between line and the return neutral. In
normal circumstances, these two wires are balanced, and any difference
current usually indicates a short circuit or other electrical anomaly like a surge
impulse is present.
B Circuit breaker protection: A circuit breaker is an electrical switch designed to protect an electrical
circuit by overload or short circuit. Its basic function is to detect a fault
condition and interrupt current flow.
3.4.1.1.
Fault current protection
The standards recommend decoupling and filter capacitors to PE for decoupling surge pulses. This is the reason
for tripping fault current protection relays that interrupt the mains to the EUT supply. For eliminate the
circumstance use one of the following options:
Remove the fault current protection
This solution does not limit the current to PE. The surge test as other EMC tests with higher currents to PE are
possible. The user must take care to the circuit with no fault current protection. Only trained professional people
are allowed to perform such tests. Some countries do not allow to operate without fault current protection.
Using of insulating transformers
An insulating transformer separates the circuit from the test circuit. The Fault current detector (FI protection)
cannot detect the earth current in the EUT circuit.
The fault current safety detection function in the generator circuit is disabled. The user must respect
this circumstance. For a safe operation he must follow the electrical rulers.
Behind the insulating transformer the neutral and PE must be connected for a proper phase synchronization of
the generator. In case of a 3-phase system the user must perform similar.

Operating Manual V 1.06 19 / 143
3.4.1.2.
Fuses for EUT with smaller nominal currents
The EM Test pulse generators have no built in fuse for the EUT power supply. It is in the scope of responsibility
of the user to protect the EUT external for the rated current.
The design of the external fuse must be match the following rules:
- fuse dimension must be equal or smaller than the rated EUT current of the connected test
generator
- fuse must be designed for protect the connected EUT device under test in malfunction
Example of external circuit breaker
Circuit breakers in the building are designed for 32 A. A circuit breaker box with 16 A protection is
installed between the building supply and the test generator.
Test generator and EUT are now fused for 16 A rated current

Variable voltage transformers adjustment procedure
The compact NX5 is able to control an external voltage source with a 0-10V analogue dc signal.
The 10V level corresponds to the max. output voltage of the connected voltage source. For the correct setting it
is necessary to know the max. output voltage of the source. For setting for ac or dc source the same procedure is
necessary.
Setup for adjust the external voltage variac to the compact NX5
The voltage setting is a regulating procedure where one
winding of the motor-variac is approx. 1.9 V.
Additionally the control needs some mechanical
tolerance for stop the step motor. Therefore the
selected voltage is normally in a tolerance of 4 V
The motor-variac control has an internal dead-zone
where the voltage will not be adjusted.
The following procedure will guide the user through the Set Voltage procedure.
The setting procedure for Vmax and Vnom is listed in the figures below.
If the output voltage is out of the tolerance, change the Vmax voltage and repeat the procedure.

Maintenance setup and service
7.1.
General
Inside the test system there are no adjustable elements accessible to the user neither for calibration nor for
maintenance purpose.
The housing of the test system must not be opened. Should any maintenance or adjustment become necessary,
the whole test system, together with an order or fault report, should be sent to an AMETEK CTS service center.
7.2.
Maintenance and cleaning
The generator is absolutely maintenance-free by using a solid state semiconductor switch to generate transients.
Maintenance by the user is restricted to cleaning the outer housing, performing a function check and verification
of the pulse parameters.
In general, a moist cloth is sufficient for cleaning the outer housing, including the touch panel. If necessary add a
small amount of a mild, non-foaming household cleanser.
No chemicals (acid, etc.) should be used for cleaning purposes.
Before beginning to clean the test system ensure that it is switched off and the mains power cable is unplugged
from the supply.
7.3.
Test set- up
When setting up the test national and international regulations
regarding human safety have to be guaranteed.
It is recommended to connect the simulator to the ground reference
plane of the test set-up.
The generators of the compact NX series and their coupling networks,
can be linked together to a fully automotive test set-up.
The set-up communicates via the Ethernet / optical link is controlled by
software. For setting up the system see the following figures:
7.4.
Insulating- or external transformer for EUT power supply
The recommended power of an external transformer must be > 500VA. The reason is the
capacitive current of the internal filter capacitors inside the compact NX5.

Calibration and verification
7.5.1.
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
7.5.2.
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 are performed during the life cycle of a 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 recommend 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.
7.5.3.
Calibration of Accessories made by passive components only:
Passive components do not change their technical specification during storage. Therefore the measured values
and the plots stay valid throughout the storage time. The date of shipment shall be considered as the date of
calibration.
7.5.4.
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 to refer 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

Accessories and options
ESA Adapter for adapt different power mains connectors
As accessories adapters to different power mains connectors are part of the
delivery of EM TEST surge generators. E.g. these are adaptors for Schuko - US
- AUS - UK power mains connectors.
Most of these commercially available power mains sockets cannot withstand
surge voltages higher than 4000V. Therefore each of these EM TEST adaptors
are labeled to be used up to 4000V maximum.
In case that the EM TEST surge generator can generate higher surge voltages
than 4000V a sparkover at the power mains socket may occur.
Customers shall be aware of this matter and shall not use higher voltages than

Warning
If the user reduces the test voltage in Quick Start or in the Manual Standard Test Routine, the
storage capacitor will be discharged only by the burst pulses. The result is a higher test
voltage on the EUT than indicated on the display until the storage capacitor is discharged to the
preselected value.
If the voltage reduction is several 100V the discharge time to the correct test voltage can be
some seconds. The discharge time depends on the repetition rate tr and the duration td of the
burst pulse.
Pressing STOP / START will discharge the storage capacitor over the discharge resistor
immediately. After the START the test will continue with the correct voltage level.

Coupling/decoupling network
The decoupling part of the coupling network has to:
- filter the interference pulses in the direction to the power supply;
- protect other systems that are connected to the same power supply and
- realize a high impedance of the power supply, e.g. battery supply.
9.5.1.
Coupling/decoupling network for ac/dc power lines
The coupling network couples the EFT pulses via 33 nF capacitors onto the AC or DC power lines. As coupling
devices capacitors of sufficient strength and bandwidth shall be used according to IEC 61000-4-4.
The coupling on signal lines can usually not be effected capacitive without interfering with the signal flow. It is
often impossible to contact the required circuit (direct), e. g. coaxial or shielded cables. In this case the coupling
is realized with the capacitive coupling clamp. The interference simulator can be connected on both sides of the
coupling clamp.
Coupling method:
Test duration: At least 2 minutes in positive and negative polarity. The test duration must be at least as long for
examine all functions of the EUT
Coupling IEC 61000-4-4 edition 2 (2004) and later versions requires to couple all lines simultaneously in
Common Mode coupling.
This means that a burst test needs two tests with 60s (positive and negative 60s each).
IEC 61000-4-4 (1995, 2001) requires all line combination to be tested individually.
A 1-phase EUT needs to test all combination L, N, PE, L+N, L+PE, N+PE, L+N+PE each with
two tests with 60s (positive and negative 60s each). Total test time 14 x 60 seconds
9.5.2.
Capacitive coupling clamp
- The coupling clamp is not matched by 50 Ω. If the clamp is matched
there exists an additional magnetic coupling, which may cause
completely different test results.
- The clamp should be placed in a distance of 0.5m to the equipment
under test. When the distance is shorter distances, the EUT may be
influenced by radiation.
- If the EUT is includes two separate equipment, the test should be
conducted on each single equipment with the required distance.
EM TEST Compact NX5
Operating Manual V 1.06 89 / 143
9.6.
Burst Test Setup
- The test generator and the coupling network should be connected to the reference ground plane (acc. to high
frequency requirements).
- The equipment under test must be isolated from the reference ground plane. The distance should be 10 cm.
Being part of the EUT, these requirements are also recommended for all connected cables. The EUT should
only be grounded if this is recommended by the installation guideline. For safety reasons, the test without any
ground connection should be conducted as well (at 100MHz 1 m ground cable lenght has an impedance of
about 600 Ω)
- Whenever possible the test set-up and the cabling should always be the same; e.g. for testing power lines it
would be possible to fix the cables on the test table for all tests in the same way.
- Lines under test and all other lines should be decoupled strictly.

Test setup with capacitive coupling clamp
When using the coupling clamp, the minimum distance between the coupling plates and all other conductive
surfaces (including the generator), except the ground reference plane beneath the coupling clamp and beneath
the EUT, shall be at least 0.5 m.
The distance between any coupling devices and the
EUT shall be (0.5 − 0/+0,1) m for tabletop equipment
testing, and (1,0 ± 0,1) m for floor standing equipment,
unless otherwise specified in product standards. When
it is not physically possible to apply the distances
mentioned above, other distances can be used and

WARNING
The internal coupling network is designed for mains frequency 50 Hz / 60 Hz.
When L – N coupling is selected an additional current of approx. 1.5 A flows, caused by the
18 F coupling capacitor and the pulse forming network. A similar current appears during the
couplings to PE.
Tests with 400 Hz mains frequency destroy the coupling network. An external coupling
network is recommended with inductors and capacitors matched to the 400 Hz mains

(EUT monitor 1)
Break the test and go to pause status. For continue the user must press the
START/PAUSE button or continue in iec.control software.
NOTE: The EUT monitor input 1 must go to open status before press continue
Break (hold)
(EUT monitor 2)
Keep in pause status as long the EUT monitor 2 input is grounding.
After release the break, the test will continue automatically.

Setup current peak limiter for surge current
The peak current limiter stops the test run when during a test the measured peak current of a surge pulse is
higher than the preselected current value. This safety function protects the EUT for further surge pulses that can
become any dangerous situation.
Depends of the different impedance of the surge generator, one current limiter for both impedances (2 , 12 ) is
available.
Select SURGE Menu / Current Limiter
Set peak current limiters
I_D = Current limiter Differential mode (line to line): The generator impedance is 2
I_C = Current limiter Common mode (line to ground): The generator impedance is 12
REMARK
The current limits in Software and Manual operation are two individual settings.
Software uses the software settings for I_D and I_C
Manual operating uses the device settings for I_D and I_C
Note: Surge pulses with the coupling position for data lines use the settings of common mode. This is general used for the
coupling network CNV 504 / 508 series with have an impedance of 42 (2 + 40 ).
Using a coupling network coupling NX-series uses the limits of differential and common mode.
