Frequently Asked Questions & Answers
Here you can find Q&A related to customization, service, and quality of overvoltage and undervoltage protectors:
Contact Us    >>
What precautions should I take when installing the protector?
-Correct wiring: Be sure to distinguish between the input terminal (for power input) and the output terminal (for load output), and ensure that the neutral (N) and live (L) wires are connected correctly. -Tighten screws: During installation, tighten the terminal screws with appropriate torque to avoid heat damage caused by poor contact. -Environmental requirements: Do not use the product in humid, wet, or corrosive environments to prevent product damage or electric shock.
What might be causing the protector to frequently trip or experience unexpected power outages?
-Grid issues: The grid voltage itself is unstable, fluctuating significantly, or at a critical point in the protector's operating range; the neutral conductor may have poor contact. -Product settings: The protector's overvoltage or undervoltage protection settings may be incorrect. -Product failure: An internal component of the protector (such as the disconnect relay) may be faulty.
What should I do if the protector itself malfunctions?
-If you encounter a malfunction that cannot be resolved yourself, or if the product is severely damaged and malfunctions, please stop using it immediately and contact our professional after-sales service personnel for inspection and repair. Never disassemble or repair the product yourself, as this may cause safety hazards or further damage to the product.
