This symbol warns of a potential risk of shock hazard. The symbol on an instrument shows that 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 contact with these voltages.

This symbol indicates where a caution is required. Refer to the operating instructions located in the manual in order to protect against personal injury or damage the equipment.

GROUND Indicates protective Ground Terminal

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 equipment. 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 understood and met.

Power Supply The equipment is intended to operate with a power supply not to exceed 250 volts between phase and neutral or between phase and ground. A proper ground connection through the ground connector of the power cord is essential for safe operation.

Grounding the Generators The generators are grounded through the power cord. To avoid electric shock, plug the power cord into a properly installed receptacle which was tested by a qualified electrician. Have the test performed before connecting equipment.

Without the protective ground connection, all parts of the generators are potential electric shock hazards. This may include components which appear to be insulated. The equipment MUST NOT BE USED if this protection is altered.

Use the Proper Power Cord Use only power cords and connector specified for your product. Use only power cords in good condition.

Use Proper Fuses To avoid fire hazard, use only fuses as specified in the parts listing for your product - matching type, voltage and current rating.

Do Not Remove Covers or Panels To avoid personal injury, do not operate the generators without panels and covers.

Do Not Operate in an Explosive Environment

Electric Overload Never apply power to a connector which is not specified for that particular voltage/current.

CAUTION

Before using this equipment, read the user manual and the

separate delivered safety manual carefully

1.3. Responsibility of the operator

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.

CAUTION

The purpose of this instrument is the generation of defined interferences signals for EMI immunity testing. Depending on the arrangement of the test rig, the configuration, the cabling and the properties of the EUT itself, a significant amount of electromagnetic radiation may result that could also affect other equipment and systems.

The equipment is designed to operate in industrial environment. For operating in other or sensitive environment, such as light industry, airport area…, the user may use a shielded room for operate.

The user himself or herself is ultimately responsible for the correct and controlled operation of the rig. In case of doubt, the tests should be carried out in a Faraday cage.

1.4. General hazard

Before applying power to the system, verify that your product is configured properly for your particular application.

WARNING

The generators and their accessories operate at high voltages.

Hazardous voltages may be present when covers are removed. Qualified personnel must use extreme caution when servicing this equipment.

Circuit boards, test points, and output voltages also may be floating above (below) chassis ground. The design of external insulation must be such that it exceeds the maximum impulse voltages of the generator (5.5 kV or 7.0 kV).

Only qualified personnel who deal with attendant hazards in impulse generators, are allowed to perform installation and servicing.

Ensure that the AC power line ground is connected properly to the Power Rack input connector or chassis. Similarly, other power ground lines including those to application and maintenance equipment must be grounded properly for both personnel and equipment safety.

Always ensure that facility AC input power is de-energized prior to connecting or disconnecting any cable.

The user must ensure that the output power lines are labeled properly as to the safety hazards and that any inadvertent contact with hazardous voltages is eliminated. Guard against risks of electrical shock during open cover checks by not touching any portion of the electrical circuits. Even when power is off, capacitors may retain an electrical charge. Use safety glasses during open cover checks to avoid personal injury by any sudden component failure. Neither AMETEK CTS GmbH, nor any of the subsidiary sales organizations can accept any responsibility for personnel, material or inconsequential injury, loss or damage that results from improper use of the equipment and accessories.

2. Before Activating the Equipment

2.1. Damage due to Shipment The instrument was tested before shipment and was packed carefully on a transport palette. Each box is marked with a detailed list of the contents.

Before activating the equipment, check for damage which may have occurred during shipment. Check each container as well as the generator itself. In case of physical damage, contact the manufacturer before operating the unit.

Figure 1 – Instrument

Figure 2 – Rack

Figure 3 - System

2.2. Power requirements Prior to turning the equipment on, check that the selected voltage corresponds to the supply voltage.


1.00 10 / 50

The position of the voltage selector must correspond with the mains. If you change the mains voltage, replace the fuses according the recommended value on the number plate.

First - check the 115 V / 230 V voltage selector where applicable!

Do not connect 230 VAC into the 115 VAC units.The result could be a severely damaged unit.

Figure 4 - Power Settings

If power to the equipment of Class I is supplied by an auto-transformer which is connected to a higher supply voltage, the base of the auto-transformer must be connected to the neutral of the power supply.

Equipment of Class I, which is supplied with a 3-phase power cord, must only be connected to a grounded receptacle. The protective ground connection must not be disconnected or otherwise interrupted.

Each interruption or disconnection of the protective ground connection inside or outside the equipment may cause electric shock.

Connecting different units with each other or to a personal computer for remote control may be performed only with cables recommended and/or supplied by the manufacturer.


1.00 11 / 50

2.3. 3-phase EUT power lines The connectors for 3-phase EUT power lines on the devices is realized with CEE connectors. Please take care to connect carefully the correct plugs during installation. Important is a direct connection between neutral and PE from the power supply. Otherwise you get problems with the floating neutral star point and inconvenience or malfunctions during the test. The figures show the correct mapping of the plugs of the CEE connectors.

Figure 5 - Female Receptacle

Figure 6 - Male Plug

2.4. Fuse for the EUT power supply

The 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.

CAUTION

The design of the external fuse must be matching 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 fuse Fuse in the building is designed for 32A. A Fuse box with 16A fuse protection is installed between the building supply and the test generator. Test generator and EUT are now fused for 16A rated current

Figure 7 - External Fusing

Example 16A protection with a 100A installation with a 3-phase fuse box.

The user has protected his Equipment Under Test with this additional fuse box for a rated current of 16A.

Figure 8 - Example of External Fuse

3. Safety functions

The test area must be organized so that only those involved in the test may enter it. In the case that the safety circuit is used to control the complete area, an additional interlock contact must be used to directly protect the operator from contact with the DUT. Neither the DUT nor any cables or accessories must be touched during the test. During work on the DUT, the test procedure must be stopped and the DUT disconnected from the power mains supply. Coupling devices have no safety functions built in, because these functions are integrated in the generators.

3.1. Safety circuit

The safety circuit will switch off the high voltage and the TEST ON button of the unit.

3.1.1. Safety circuit for compact NX and NSG 3000A series

The safety circuit locks the system and enables the generation of the high voltage impulses in the generators.

Design Each device that has internal relevant high voltage unit, includes a safety circuit. The safety circuit works like an “open collector circuit”, where the external safety loop must be closed for switch on the high voltage.

Safety circuit closed The device will generate high voltage pulses after start

Safety circuit open The device will switch off the high voltage and discharges the high voltage circuit

Figure 9 - Safety Circuit

Figure 10 - Safety Circuit Diagram

3.1.2. Safety circuit on Rack Systems

Rack Systems have a separate safety circuit, driven by the mains supply voltage. Release the Safety Circuit button will disconnect the mains power from the devices and EUT supply. For power on it is necessary to unlock the red colored safety button manually by turning.

Figure 11 - Rack Stop Button

National Standards for safety circuits can differ from the example above.

The user is responsible for the correct design of his safety circuit.

3.3. Earthing of devices Earth Bolt

Generators must be grounded to the reference ground plane. Generally, the generators are equipped with an aluminum earth bolt (8x30mm) at the rear side of the device.

For contact the earth bolt there are the following connections: - Screw M4 x 12 mm tapped hole - Ø 4mm x 20mm holes for 4mm banana plugs The drawing shows the dimensioning of the earth bolt.

Figure 16 - Earth Connection

Earth connection with a tress

The earth connection must be designed as a low ohmic and low inductance connection as illustrated as example in the picture at the right side.

This solution allows the user for fast exchange the device.

Figure 17 - Earth Connection

Tress Earth connection with a brass bar

Alternative method is using a brass bar equipped with banana plugs and additional fixed with a M4 screw as illustrated at the right-side picture.

This is a solution preferred for fix mounted test setup installation.

Figure 18 - Earth with Brass Bar

3.4. FI 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 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. Using of insulating transformers An insulating transformer separates the circuit from the protected path. The synchronization works between line and PE and therefore a connection between neutral and PE is necessary. Without this connection the stray capacitance defines the phase sync.

Figure 19 - Example with Insulating Transformers

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.


1.00 15 / 50

4. Testing and Precautions

All tests offered by High Voltage or EMC generators are immunity tests on electronic equipment or devices. These tests are potentially dangerous to the operator. It is the responsibility of the user to avoid critical failures and risks to the environment and the operator.

National and International regulations regarding human safety must be followed.

Individuals with certain health conditions (e.g. with a heart pacemakers or similar devices), should not participate in testing.

Long power supply lines to the EUT may radiate energy which may interfere with other instruments unrelated to the generator. It is the responsibility of the user to determine whether to conduct immunity tests in a given area. Generator and coupling/decoupling voltage power supplies must be grounded and connected to reference plane.

4.1. Precautions to be taken • EMC and High Voltage test areas must always be supplied by a decoupled and well-known power supply. • The decoupling can be realized either by

- filtering - or the use of an isolating transformer

• When using isolating transformers, the fault current safety devices normally don’t trip. • EMC and High Voltage test areas must always have a clear grounding strategy. All coupling/decoupling high power

voltages and all LISN’s must be strictly and securely connected to the ground reference plane of the test setup. • Please ensure the correct current back flow to the generator. Missing connections can cause extremely high voltages and

may become a health hazard. Therefore, it is absolutely necessary to use ground reference planes which are connected to a protective ground.

4.2. Failures and Heavy Strain If it is determined that a safe operation of the equipment due to failure or heavy strain is no longer possible, the supply voltage must be disconnected, and the equipment protected from unintentional use.

Unsafe operation is determined as follows: • the equipment shows visible damage • the equipment is not working • the equipment has experienced severe stress during transport • the equipment was stored in an unsuitable environment for an extended period of time.

Please exercise good judgement in determining whether a device is unsafe for operation.

4.3. 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 specify this special solutions.

• 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.


1.00 16 / 50

4.4. Interference to the environment

The AMETEK CTS interferences generators are instruments with a functionally emission of electromagnetic interference during the test (e.g., ESD, EFT, conducted RF, etc.). Therefore, a disturbance of the environment cannot be excluded.

The user has an obligation to use a suitable test environment in order to minimize influences to the environment. This may require a suitable screening or to test in a shielded room.

Next should be considered during the test, that nearby are no disturbers such as (switching relays or drives with frequency converters etc.) that can influence through their emission the test.


1.00 17 / 50

5. Testing

The generator can be operated locally from the front panel or remotely from the computer. When it is necessary to observe the EUT during the test, it can be more comfortable to operate locally. The tester is nearer to the EUT and therefore faster to switch off the test generator in EUT fail condition. When the computer fails, the Test On button on the generator front or the Fail 1 input must be used for switching off the test.

5.1. Safety Precautions • The test area must be secured that only authorized test personnel may enter it. • Working alone with high voltages is dangerous. • The high voltages must be switched off when nobody is present. • Neither the EUT nor cables or accessories must be touched during the test. • Make sure all high voltage connections are adequately taped or otherwise insulated to prevent accidental contact by you

or neighboring colleagues. • Keep one hand in your pocket when probing high voltage circuits or discharging capacitors. This reduces the peril to

touch the high voltage with both hands. • While working on the EUT, the test procedure should be stopped and the EUT disconnected from the voltage power

supply. • The EUT must be tested within a safety container or within a protected area. In extreme circumstances the EUT may

ignite or explode as a result of internal damage.

5.2. Danger from EUT

CAUTION

The device being tested may become defective and ignite due to the influence of the applied test signal.

The storraged energy inside the test simulator must be to consider. This energy can destroy or damage the EUT even when the EUT operates under normal conditions.

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 in the vicinity of the test area. • The user is responsible for the correct EUT protection. The device under test is to be secured in such a way that no

dangerous conditions arise.

CAUTION

Never touch the EUT or anything connected to the EUT during a test

It is absolutely necessary to observe and comply with all safety instructions.

6.2. Installation put in service This chapter includes a checklist with steps that should be taken before the generator is switched on and put into operation.

6.3. Safety instructions for installation and initial installation

National regulations in installation and operation of electrical equipment must be respected.

CAUTION

The compact NX / NSG 3000A test system is not suitable for use in an explosive atmosphere.

CAUTION

Connect the EUT only after the initial system setup has finished.

6.3.1. Qualifications of the staff Knowledge of electrical engineering and electromagnetic compatibility is required to install 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.

6.3.2. Installation The test system conforms to protection class 1. Local installation regulations must be respected to ensure the safe flow of leakage currents.

CAUTION

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 generator 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


1.00 21 / 50

Faraday cage.

6.4. Installation of the compact NX / NSG 3000A

6.4.1. Installation site Place the test system so that there is enough free space around the cooling air inlets on both sides and behind the fan outlet on the rear panel.

6.4.2. Voltage free switching Make sure that the cables can be connected without hindrance and disconnected without problems. The complete voltage disconnection from the device is carried out by disconnecting the cables. Make sure that capacitors inside the device can still be under voltage, even in an emergency.

6.4.3. 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.

Figure 20 - Grounding and power connection

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.


1.00 22 / 50

6.4.4. Mains Switch and fuse The mains power voltage indicated on the instrument must correspond with the local supply voltage (mains voltage: 85–265 Vac, universal power unit, mains frequency: 50–60 Hz). Use cables of sufficient current capacity.

Figure 21 - Mains Switch, fuse holder and power input

To replace a fuse: 1) Disconnect the mains cable 2) Pull the fuse holder out of the connector 3) Remove the damaged fuse(s) 4) Insert 1 or 2 fuses (4 A / 115V and 2 A / 230 V slow blow) 5) Replace the fuse holder 6) Plug the mains cable into a power outlet with a solid ground

connection 7) Switch the system on and operate as instructed in this manual

6.4.5. Connecting the generator to the ground reference The earth connection to the GRP should be low inductive and low ohmic. The cross-section of the earth connection should be at least 6 mm2. A braid of stranded wire or a flat copper or brass strip is better.

Figure 22 - Connection to reference ground

Connection to reference ground For burst tests, the generator must be placed on a ground reference plane which is connected to ground.

A low inductive high frequency ground connection between the test system and the ground reference plane (GRP) is absolutely essential for performing burst tests correctly.

6.5. Fuses for EUT with smaller nominal currents

The AMETEK CTS 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.

CAUTION

The design of the external fuse must be match the following rules:

Fuse 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

Figure 24 - External Circuit Breaker

6.6. EUT power ON/OFF with supply Line to Line (400V)

CAUTION

To operate the generator internal CDN with line to line voltages of 400 V,

the generator must be designed for this higher line to line voltage

The internal electrical switch interrupts the power on line L. Using a two-phase supply (L-L), the second line is connected to the Neutral EUT path and can’t be interrupted by the generator. The following setup with an external contactor will interrupt both lines L1 and L2 (connected to N-path). It is controlled via the potential-free contact of the warning lamp. The design and installation of the contactor is in the responsibility of the user.

6.9. Phase indicator (compact NX-models only)

The phase indication shows the correct connection of the supply to Phase and Neutral input of the compact NX . For the generator hardware, both, L and N paths are potential free and a reverse connection is not relevant for the generator operation. It is in the responsibility of the user to decide to run the test in correct phase-neutral connection. Anyway, with wrong phase connection it is possible and normal to measure a voltage between neutral and earth.

8.3. Connecting coupling NX with compact NX generator When setting up the test national and international regulations regarding human safety have to be guaranteed.

Figure 34 - Adding coupling

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.

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 via arrestors(GDT) or Avalanche breaking diodes (ABD) is the preferred coupling method for unshielded outdoor symmetrical communication lines. The coupling network also has the task of splitting the surge current into multiple pairs in multi-conductor cables. The internal generator matching resistor Rm2 (25 Ω) is replaced by the Rc = 25 Ω in the DCD coupling / decoupling network.

10. Quick start guide capacitive coupling clamp CCI

The CCI is used to couple EFT/burst pulses to I/O lines as required in different European and international standards for immunity testing. The coupling of the Electrical Fast Transients EFT/burst to signal lines can usually not be achieved by discrete capacitive coupling 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 by the capacitive coupling clamp. The interference simulator can be connected on both sides of the coupling clamp. Normally the clamp is connected directly to the coaxial output of the generator (50 Ohm output), but it also can be connected and controlled via the external coupling network.

Figure 58 - CCI Connection

To activate the coupling via the coupling clamp, the appropriate coupling must be selected on the generator.

11. Quick start guide HSC 4-8, CNI 508N2, SPN 508N1

11.1. HSC 4-8 Coupling / decoupling network The HSC 4-8 is a specifically designed CDN for testing high-speed communication lines. Its unique design allows data rates of up to 1,000MBit/s to be transmitted without degradation by the coupling/decoupling network. The decoupling network protects the auxiliary equipment limiting the residual voltage to max. 50V@2kV for common-mode surge test pulses.

Moreover, the HSC 4-8 fully supports PoE and PoE+ standard requirements as per IEEE 802.3.

The HSC 4-8 may also be used for testing shielded cables as per IEC/EN 61000-4-5, Fig. 16.

Figure 60 - HSC 4-8

It simplifies the test set-up and offers proper decoupling of the auxiliary equipment as well as a high safety for the operator as the surge is coupled through the HSC 4-8 rather than being directly applied to the metallic case of the DUT. The HSC 4-8 may also be used to couple Ring Wave impulses (0.5 us/100 kHz) and burst pulses to shielded cables .

11.2. CNI 508 N2 Coupling / decoupling network The CNI 508N2 is the predecessor of the HSC 4-8 and can also be used for testing high-speed communication lines. Its unique design allows data rates of up to 1,000MBit/s to be transmitted without degradation by the coupling/decoupling network. However, unlike the HSC 4-8, it cannot be used for ringwave tests.

Figure 61 - CNI 508N2

11.3. SPN 508 N1 Surge Protection Network The SPN 8 protects the auxiliary equipment with a residual voltage of less than 10V. This Ethernet surge protection device can alternatively use for all other application where the user must protect his devices from any overvoltage.

The SPN 8 has a galvanic isolation of the signal between protected and unprotected side. For decoupling the pulse in direction to the AE port, the surge protection network SPN 508 N1 must mandatory be connected at the opposite side of the EUT at HSC 4-8 or CNI 508N2.

11.7. General Coupling of the surge pulses is achieved by means of the coupling / decoupling network HSC 4-8. For additional protection of the auxiliary equipment by reducing the residual voltage level the SPN 508N1 is used.

The HSC 4-8 design is based on the IEC 61000-4-5 (Ed 3.0: 2012) figure 11, IEC 61000-4-12 (Ed. 3) figure 10.

The HSC 4-8 allows the following couplings with separate input connectors: - Surge and Ring wave pulses to data-lines - Surge pulses to shield - Burst pulses to shield

For an additional overvoltage protection of the AE port the SPN 508N2 can be used for limiting the residual voltage to approx. 10V.

11.8. Test methods for Surge and Ring Wave to high speed datalines The IEC 61000-4-5 Ed.3 Surge standard shows in figure 11 the coupling network for testing high speed datalines. The solution for coupling/decoupling is based on the existing methods of surge testing. There are two different Methods for testing surge pulses on datalines.

Coupling to shielded lines


1.00 47 / 50

Test to shielded line is adapted from the figure 16 where the surge is applied direct to the shield of the data cable.

Figure 65 - Coupling to Shielded Lines

Coupling direct to high speed lines

Test with coupling direct to the data-lines is based to figure 11 of IEC 61000-4-5 standard. The surge is applied direct to unshielded symmetrical high-speed data-lines. For decoupling and protection, it is necessary to use separate devices of the HSC 4-8 assembly.

Figure 66 - IEC 61000-4-5

11.9. Test setup The SPN 508N1 protects the auxiliary equipment with a residual voltage of less than 10V. Generator output plugs

The Surge and Ringwave output plugs are located at the rear side of the impulse generator. The surge generator impedance is 2 Ω. The additional impedance is inside the HSC 4-8.

Surge, Ringwave: Output HV –COM on rearside of the generator with direct coupling.

Figure 67 - Surge output on rearside

Figure 68 - Burst pulse output

Grounding: The generator and the used devices of the HSC 4-8 assembly must be grounded properly to the reference ground.

11.10. Surge test to shielded datalines This test will couple the surge pulse to the shield of a shielded RJ24 data-cable. The cable to the EUT must be mandatory a shielded cable.


1.00 48 / 50

Figure 69 - Setup for surge test to shielded datalines

The surge current on the cable shield can be very high and is limited by the 2Ω generator impedance. To use the SPN 508N1 protection device will protect the AE port side and all connected devices.

The surge coupling voltage and current to the lines depends on the impedance connected at the HSC 4-8 AE port.

In case of a short circuit as shown in figure 5.4, the coupling to the lines is nearly 1:1 and a current wave 8/20us appears.

Is the at the AE Port a high impedance (open circuit), an impulse waveshape 1.2/50us appears at the EUT Port

11.11. Surge test to datalines This test will couple the surge pulse direct to the 8 datalines of the RJ45 cable. The cable to the EUT can be a shielded or unshielded data-cable. Figure 5.5 shows the test setup for surge to datalines.

11.12. Surge test to data-lines with SPN 508N1 protection In case of a high protection level of approx. 10V at the AE port, the user can connect additional the SPN 508N1. This protection will separate the AE side the surge by a galvanic insulation from the surge circuit. Figure 5.6 illustrates the setup with using a SPN 508N1 protection device.

Figure 72 - SPN 508N1 Use

11.13. Burst test to data-lines The burst pulse is applied from the 50Ω front side EFT output to the blue HV-BNC plug of the CNI 508N2. The coupling is to the shield. The burst pulse can be measured on the shield as on the data-lines.
