2. Safety Precautions

2.1 Placement Guidelines

Place it on a stable work surface; avoid tilting or inverting it, and keep it away from sources of vibration;

Isolation Transformer: Keep it at least 0.5 meters away from the main unit to avoid electromagnetic coupling interference;

The premises must be free of strong electromagnetic interference, corrosive gases, and flammable or explosive materials, and must be well-ventilated;

The equipment must be placed at least 1000 mm away from walls and surrounding structures (such as other test equipment and shelves) to facilitate maintenance; at least 2000 mm of space must be left in front of the equipment to ensure smooth operation and keep the surrounding area free of obstructions.

2.2 High-Voltage Safety Standards

2.2.1 Security Check

Verify that the equipment’s power supply voltage matches the mains voltage (AC 220 V ±10%, 50/60 Hz), and ensure that the power supply is properly grounded and that the grounding wire is free of damage or looseness;

Grounding Requirements: The host unit’s protective grounding terminal (PGND) must be connected to ground, with a grounding resistance of ≤4 Ω, to ensure safe discharge of high voltage;

Confirm ambient temperature: 15°C to 35°C, relative humidity: 10% to 75% (no condensation), atmospheric pressure: 86 kPa to 106 kPa;

Operators must have dry hands and must not wear any metal jewelry.

2.2.2 Safety Requirements for Operational Procedures

The equipment generates high voltages (up to 6 kV) and high-current surges during operation. Do not touch the pulse output connector, the EUT terminals, or the CDN port under any circumstances.

Before switching connections or replacing the EUT, you must first ensure that the high-voltage output is turned off (the HV indicator light is off) and wait at least 5 minutes to ensure that the internal high-voltage capacitors are completely discharged.

Do not eat or drink during the test to prevent accidents caused by electric shock.

When multiple people are involved, clearly define roles and responsibilities, and confirm them with each other before starting the test to avoid errors.

Do not disassemble the equipment or work with the casing open without authorization. The equipment contains high voltage, and repairs by non-professionals may result in electric shock or damage to the equipment.

2.3 Emergency Response Measures

In the event of an electric shock: Immediately shut off the main power supply to the equipment, move the operator to a safe area, administer first aid if necessary, and contact medical personnel.

Equipment Malfunction (Smoke, Unusual Noises, Strange Odors): Immediately shut down the equipment, disconnect the power supply, and disconnect all wiring. Do not turn the equipment back on. Contact the manufacturer for repairs.

Abnormal surge output: Pause the test, contact the manufacturer for troubleshooting, and do not touch the test port directly with your hands.

2.4 Other

For matters not covered in this manual, please proceed with caution or contact us.

3. Surge Test Procedure

3.1 Hardware Wiring Sequence

Refer to Section 1.3 and connect the wires in the following order:

Computers, software, or other AE auxiliary equipment > Communication cable > SG61000-5C rear AE port > SG61000-5C front CDN output port > Communication cable > EUT (Equipment Under Test).

3.2 Confirmation of Test Parameters

3.2.1 Selection of Test Level

Based on the EUT installation environment and product standards, select the corresponding test level (the priority levels are listed in the table below); lower levels must meet compatibility requirements:

3.3 Equipment Warm-up and Self-Test

Turn on the power switch on the front panel of the host; the device enters standby mode, the power indicator light turns on, and the cooling fan starts up.

Wait 5 minutes for the device to warm up, and check that the touchscreen is displaying properly and that no error messages appear.

3.4 Introduction to the Touchscreen Program

Program Startup Screen: ① Settings screen for the built-in digital oscilloscope; ② Important usage notes (this feature is not yet fully developed; do not perform any operations here at this time); ③ System information screen; ④ Chinese/English language switch; ⑤ Surge test screen.

Figure 4

3.4.1 Oscilloscope Function Settings Interface

Just check all the boxes, and the current surge waveform will be displayed automatically after each surge test.

3.4.2 Surge Test Interface

① Surge voltage and polarity settings; ② Surge interval settings; ③ Number of surges; ④ Click to start or stop the surge test.

Figure 5

Note: To automatically display the current surge waveform on the screen, set the surge interval to at least 10 seconds; otherwise, the program will not have enough time to display the surge waveform.

3.5 Click “Start Test”

Once you have completed the above wiring and settings, click “Start” to begin the surge test.

3.6 Determining Whether the EUT Has Passed the Test

4. Post-Test Procedures

4.1 Test Completion

If the EUT is visibly damaged during the test, immediately tap “Stop Test” on the touchscreen.

If no abnormalities occur during the test, wait for the surge test to complete automatically.

Wait 5 minutes to ensure that the high-voltage capacitors inside the main unit have completely discharged before replacing the EUT for testing, or turn off the power to the main unit and the Isolation Transformer.

4.2 Post-Test Organization and Cleanup

Verify whether the EUT has passed the test (no performance degradation, no damage).

Clean the test area and wipe it down with a dry cloth. Do not use alcohol or corrosive cleaning agents.

Surge testing is a destructive test; it does not automatically generate a test report, but the device automatically saves the test data. You can go to “System Information,” click “Test Log,” and export the corresponding test data to a USB flash drive via the USB port. The exported file is in TXT text format.

Figure 23

4.3 Equipment Storage

4.3.1 Short-Term Storage Requirements

If the equipment is used on a daily basis, no further action is required after cleaning is completed following each test.

4.3.2 Long-Term Storage Requirements

If the device will not be used for an extended period (more than one month), please disconnect all cables and cover the device with a dust cover to prevent dust buildup.

The device should be powered on once a month for just half an hour to prevent the aging of electrical components (such as capacitors and contactors).

5. Use a discharge tube to verify the surge output

A discharge tube can be used to easily verify whether a device produces surge output.

There is no need to connect the AE equipment or the EUT. ① Connect the L1, L2, L3, and L4 output ports of the CDN surge generator together to one end of the discharge tube. ② Connect the COM port to the other end of the discharge tube.

Figure 6

Set the voltage to 4 kV and begin the surge test. The discharge tube will flash the moment the surge is output; please dim the lights in the room to facilitate observation. See the figure below:

Figure 7

This confirms that the device is indeed experiencing an output surge. If the discharge tube does not flash, please contact customer service.

6. Troubleshooting and Resolving Common Problems

6.1 The device won’t turn on

Symptom: After turning on the power switch, the device does not respond (the indicator light does not come on, and the fan does not spin).

Possible causes: ① The power cord is not properly connected or is damaged; ② Abnormal supply voltage; ③ A blown fuse; ④ A blown varistor (MOV).

Troubleshooting: Ensure the power cord is intact and securely connected. Power supply issues—such as unstable voltage, excessively high voltage, or harmonic interference—can cause the fuse or varistor to burn out. We recommend using a voltage-stabilized, pure sine wave AC power supply to power the device. Replace the fuse or varistor with one of the same type.

The following image shows the fuse locations:

Figure 8

The following figure shows the location of the varistor (MOV) inside the filtered power supply:

Figure 9

6.2 Automatic Device Restart

Symptom: The device automatically restarts when a surge occurs.

Possible cause: The ground wire is not connected properly.

Solution: Refer to sections 1.3.2 and 2.2.1. Connect the PGND grounding terminal on the back of the host to ground, and ensure that the grounding resistance is ≤4Ω; otherwise, high voltage may not be safely dissipated, causing the device to automatically restart.

6.3 The waveform contains interference

Symptom: When inspecting a standard surge waveform using the built-in digital oscilloscope (CRO port) and zooming in on the waveform, some noise is visible.

Possible cause: The built-in digital oscilloscope and CRO port are designed to make it convenient for users to quickly and easily obtain waveform data, but they may generate a small amount of noise.

Procedure: If you need to obtain the actual output waveform of the surge protection device, or if you want to calibrate the device, use an oscilloscope and a high-voltage probe to directly inspect the waveform at the CDN output terminal.
