-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.
-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.
Suggestion: First, measure the voltage at the input to see if it's normal. If the voltage is normal, there may be a product issue and further inspection or contact after-sales service is necessary.
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.
