Here are some precautions to take when using a voltage regulator:

Before installation, check whether the capacity and load of the voltage regulator are properly matched, whether the mains voltage is within the allowable range of the voltage regulator, and whether the output voltage of the voltage regulator meets the equipment requirements.

2. The selection of connection wires for voltage regulators must meet the requirements of being able to carry sufficient current capacity.

3. During normal power on start-up, do not open the voltage regulator or pull the input and output connection wires of the voltage regulator at will to avoid electric shock or other electrical safety accidents.

4. The input and output connection lines of the voltage regulator must be arranged reasonably to avoid trampling and abrasion, which may cause safety accidents caused by leakage.

5. The grounding of the voltage regulator must be safe and reliable. Running the voltage regulator directly without a grounding wire can cause personal injury such as electric shock.

6. The grounding wire of the voltage stabilizer should not be connected to public facilities such as heating pipelines, water supply pipelines, gas pipelines, etc., to avoid infringing on third-party rights or causing other hazards.

7. Regularly check the input and output connection wires of the voltage regulator to avoid looseness or detachment, which may affect the normal use and electrical safety of the voltage regulator.

8. Remember to handle the voltage regulator gently and avoid severe vibration during operation.

9. Ensure that the carbon brush spring of the voltage regulator has sufficient pressure to prevent the contact surface between the carbon brush and the coil from sparking.

10. Non professionals are advised not to disassemble or repair the voltage regulator without authorization.

11. Strictly follow the operating instructions of the voltage regulator.

Through the above introduction, I believe you have gained a deeper understanding of voltage regulators. Let's appreciate together how the guardians of this electrical world navigate steadily in the ocean of currents, adding peace of mind and comfort to our lives.
