Lethal danger from high voltages and the risk of radiating illegal electromagnetic interference. The CDN 3083-S200M may only be installed and used by authorised and trained EMC specialists (electrical engi- neers). The CDN 3083-S200M must only be used for EMC tests as set down in these operating instructions.
CDNs housing and the cables have both insulating and screening function, which can only be assured while the housing is intact. Return the damaged CDN to a Teseq service centre immediately for repair. 2.2 Installation The test system conforms to protection class 1.

2.3 Installation of an equipment under test power switch It is recommended to connect the CDN through a properly rated power switch device, which should be located close to the test setup. In order to ensure an easy and quick access to the equipment under test (EUT) power, same should be clearly and visibly labelled as a device for «EUT power on/off»...
2.3.2 Leakage current CDN 3083-S200M generates high leakage currents to ground, by specification. Therefore the EUT power supply connection needs to be free of differential circuit breaker protection. Local installation regulations must be respected to ensure the safe flow of leakage currents.

Current surge of up to 3 kA which follows the 8/20 µs curve (short circuit conditions) The CDN 3083-S200M is designed to be used with an EUT supply of up to 620 Vrms line to line and 400 Vrms line to ground at 200 A.
4 ASSEMBLING OF TEST RIG AND THE CDN SUB-UNITS The CDN 3083-S200M contains following parts: 1 Surge decoupling network CDN 3083-S200 N – L1 1 Surge decoupling network CDN 3083-S200 L2 – L3 2 Earth rails 1 Allen key, isolated...
4.1 Installation of a test rig This section describes the check-up and installation of the CDN 3083-S200M coupling network after delivery and provides a checklist on the functions of the unit after being transported or after significant changes of the test rig were performed.
4.2 Preparation of the CDN 3083-S200M Prepare the test setup according to the chosen standard and put both decou- pling network units, etc. to the place where the CDN shall be used for testing. 4.2.1 Mounting of the common earth rails Place the two surge decoupling networks in parallel to each other.
Connect the synch lines (safety banana connector) to the decoupling units. If CDN 3083-S200M decoupling networks are not placed correctly, the positioning plates can not be screwed on.

For IEC coupling, add the coupling modules INA 3080 in the middle of the positioning plate and press it slightly down into the positioning holes. Fix the INA by pushing the black quick snap-on knobs down. The CDN 3083-S200M is now ready to use.
For extended IEC coupling, add both coupling units INA 3080 on the position- ing plate and press it slightly down into the positioning holes. Fix the INAs by pushing the black quick snap-on knobs down. The CDN 3083-S200M is now ready to use.
4.3 EUT connections The CDN 3083-S200M is equipped with EUT terminals suitable for a max. wire gauge of 110 mm2 AWG 4-4/0 (230 A), torque: max. 20 Nm. The in-house power distribution needs to be equipped with a proper circuit breaker and an emergency off button as per IEC/EN 61010-1.
Figure 12: View of EUT power input connection side 4.4 Test conditions Every test rig must be planned carefully. All the instrumentation should be readily accessible and rigidly positioned. The whole test assembly should be supplied from the same mains connection in order to prevent uncontrolled flow of pulse current in other parts of the system.
5 COUPLING MODES OVERVIEW In the following all possible coupling modes are described. The following example shows a coupling from L3 to N whereby the generator High output is connected to the INA 3080 surge coupling unit input. One end is looped, in order to get the recommended 18 μF capacitance required for line to line coupling according to IEC/EN 61000-4-5.
Figure 13: Example of IEC coupling L3- N Alternative connection possibilities are summarized in table 1 hereafter. 5.2 IEC coupling modes Figure 14: IEC coupling basic configuration All IEC/EN 61000-4-5 coupling possibilities are listed. For easy understanding, the coupling network INA 3080 input is identified by X1 while the outputs are marked with X2 and X3.
