Coupling network for Surge and
Ring wave to signal and datalines
The coupling network of the CDN 117A series are designed for
coupling ringwave, surge- or telecom pulses to signal or data-
lines.
The coupling network expands the range of application of the
impulse generator of the NSG 3040A and NSG 3060A series,
for testing signal and datalines.
Main characteristics are the advantages for handling and the
easy using with banana plugs.

General
1.1.
Intended use
Coupling decoupling networks of the CDN 117A seriesare used for simulating conducted electromagnetic inter-
ference effects for immunity testing to international, national, and manufacturers’standards.
The CDN’s are designed for full compliance conducted electromagnetic compatibility (EMC) test requirements.
The application range is for testing of industrial, light industrial, household or commercial equipment, including
many product family and product standards as per following basic standards.
Only qualified personnel who deal with attendant hazards in impulse generators, can perform installation and
servicing. Before putting in service the attached safety and user manual must be read and applied. The Safety
and user manual are an essential part of the equipment and must be available to the operator always. The user
must obey all safety instructions and warnings.
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; how-
ever, 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 is located in a Faraday cage.
1.2.
Safety label on the device
Please take note of the following explanations of the symbols used to achieve the optimum benefit from this
manual and to ensure safety during operation of the equipment.
This symbol warns of a potential risk of shock hazard. The symbol on an instrument
shows that it can source 1000 volt or more, including the combined effect of normal
and common mode voltages. Use standard safety precautions to avoid personal con-
tact with these voltages.
This symbol indicates where a caution is required. Refer to the operating instructions
located in the manual to protect against personal injury or damage the equipment
CAUTION
The CAUTION symbol indicates a potential hazard. It calls attention to a procedure,
practice or condition which, if not followed, could possibly cause damage to equip-
ment. Such damage may invalidate the warranty. If a CAUTION is indicated, do not
proceed until its conditions are fully understood and met.
WARNING
The WARNING symbol indicates a potential hazard. It calls attention to a procedure,
practice or condition which, if not followed, could possibly cause bodily injured or
death. If a WARNING is indicated, do not proceed until its conditions are fully under-
stood and met.

Safety
2.1.
Safety aspects
Read the following operation manual carefully. Pay special attention to both safety and operation details!!!
Observe all of these precautions to ensure your personal safety and to prevent damage to the test equipment.
The generators correspond to Installation Category II (overvoltage category).
Symbols marked on equipment
WARNING
Risk of electric shock. Dangerous voltages are present.
Use extreme care. Refer to the manual.
GROUND
Indicates protective earth terminal
Power Mains
The equipment is not intended to operate with a power mains supply. The equipment is designed (depending
the model) to operate with maximum dc voltage up to 250 Vdc between the lines, or between line and ground. A
proper protective ground connection, through the grounding conductor in the power cord of the impulse genera-
tor, is essential for safe system operation.
Safety Ground and grounding the generators
The generators are grounded through the power cord. To avoid electrical shock, plug the power cord into a
properly wired receptacle where earth ground has been verified by a qualified service person. Do this before
making connections to the input or output terminals of the test equipment.
Without the protective ground connection, all parts of generators are potential shock hazards. This includes
knobs and controls that may appear to be insulators. The equipment MUST NOT BE USED if this protection is
impaired.
Use the proper power cord
Use only the power cord and connector specified for your product. Only use a power cord that is in good condi-
tion.
Use the proper fuse
To avoid fire hazard, use only the fuse specified in the parts list for your product, with matching type, voltage
rating, and current rating.
Do not remove covers or panels
To avoid personal injury, do not operate the generators without the panels in place or covers.
Do not operate in explosive atmospheres
The generators provide no explosion protection from electrostatic discharges or arcing components. Do not
operate them in an atmosphere of explosive gases around explosive chemicals.
Electric Overload
Never apply a generator's voltage to a connector which is not specified for that voltage range.

Read the Operation Manual of each instrument carefully!

2.2.
Testing and danger
All tests offered by the High Voltage or EMC generators are immunity tests on electronic equipment or devices.
These tests are potentially dangerous for the operator. Therefore, it is the responsibility of the user to avoid
critical failures and risks to the environment and operator.
Long and distributed lines of the DUT are able to radiate certain energy to their vicinity. Therefore, it is also the
responsibility of the user to decide whether it is allowed to conduct immunity tests in a given installation.
National and international recommendations regarding human safety must be followed.
People with certain health conditions, e.g. with a heart pace-maker or similar device, must be excluded from
testing.
When setting up the test national and international regulations regarding human safety have to be guaranteed.
Generator and coupling/decoupling network must be grounded and connected to reference plane.
2.2.1.
Coupling networks
•The coupling network has mostly no On- Off switch and no internal fuse for the EUT power supply. This is
caused the different regulation in each country. The device under test must be protected by the user in an
adequate safe solution. As an option special adapters and switches can be built in, but the user must to
specify this special solution.
•Generators and coupling devices must be grounded and connected to the reference ground.
•For coupling pulses to the lines, the coupling path must be setted.
•If a line has not to be coupled, it is necessary to disconnect or switch off this coupling path.
•Special safety adapter cables are part of the delivery.
2.2.2.
Danger from EUT
The device being tested may become defective and
ignite due to the influence of the applied test signal.
Therefore, the operator shall take the following precautions:
•As soon as the EUT ceases to operate as intended, the test shall be stopped immediately.
•In case of internal damage, the operator may be exposed to high frequency signals of high power (up to 75
Watts and more) anywhere on the EUT.
•Cables and connectors can be overloaded by high voltages or energies.
•Due to internal damage of components fire and/or explosion may occur.
•Unintended use of the EUT may cause hazardous situations near the test area.
Never touch the EUT or anything connected to the EUT during a test.
It is suggested to read the operating manual carefully and completely. It is necessary to observe and
comply with all safety recommendations.

Description
The CDN 117A is a coupling/decoupling network for coupling Surge and Ringwave impulses to unsymmetrical
signal- and data-lines. The surge impulses as per IEC 61000-4-5 can be coupled as per standard via a coupling
impedance of 5.0 µF and 40 . Alternatively, a coupling via a gas discharge tube (GDT 90 V) is possible. The
advantage is, that the GDT is built in the bridge. So, it is possible to adapt the breakdown voltage of the GDT to
the EUT line voltage.
For Ringwave application to signal and datalines, the CDN 117A offers a bridge for coupling the impulse via a
capacitor > 3 µF.
