Safety Information
- Installation and maintenance should only be performed by qualified electricians.
- Ensure the main power supply is disconnected before any installation or wiring work.
- Verify that the device's specifications (rated current, voltage) match your electrical system requirements.
- Do not operate the device if it appears damaged.
- This product is designed for indoor use in dry environments. Avoid exposure to moisture or extreme temperatures.
- The device provides protection against over and under voltage. It does not protect against short circuits or ground faults; appropriate circuit breakers must be installed upstream.
Installation Instructions
The voltage protector is designed for DIN rail mounting. Follow these steps for proper installation:
- Power Disconnection: Before beginning, ensure the main power supply to the circuit is completely disconnected at the main breaker.
- Mounting: Mount the device securely onto a standard DIN rail within your electrical panel.
- Wiring - Input: Connect the incoming AC230V 50Hz power supply to the "进线端" (Input Terminal) at the bottom of the device. Ensure correct polarity (Live and Neutral).
- Wiring - Output: Connect the load (electrical equipment to be protected) to the "出线端" (Output Terminal) at the top of the device. Ensure correct polarity.
- Secure Connections: Tighten all terminal screws firmly to prevent loose connections, which can cause overheating or malfunction.
- Verification: Double-check all wiring connections for correctness and security.
- Power Restoration: Once installation is complete and verified, restore power to the circuit.

Operation
Once correctly installed and powered, the Fafeicy voltage protector operates automatically:
- Power On: Upon power restoration, the device will initiate a delay connection sequence (≤60 seconds). The green indicator light will illuminate, indicating power is supplied to the device. After the delay, power will be supplied to the load.
- Normal Operation: During normal voltage conditions (within 170V-275V), the device allows power to pass through to the connected equipment. The green indicator light remains on.
- Over-Voltage Protection: If the voltage exceeds 275V ± 5V, the device will automatically cut off the power supply to the load within ≤1 second. The red indicator light will illuminate, indicating a protection state.
- Under-Voltage Protection: If the voltage drops below 170V ± 5V, the device will also automatically cut off the power supply to the load within ≤1 second. The red indicator light will illuminate.
- Automatic Recovery: When the voltage returns to the normal range, the device will automatically re-engage after the delay connection time (≤60 seconds), restoring power to the load. The red light will turn off, and the green light will illuminate.
Maintenance
- Periodically inspect the device and its connections for any signs of damage, loose wiring, or discoloration.
- Keep the device clean and free from dust and debris. Use a dry, soft cloth for cleaning.
- Do not attempt to open or repair the device yourself. Refer to qualified personnel for service.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power to load, green light off. | No incoming power. | Check main circuit breaker and power supply. |
| No power to load, red light on. | Over-voltage or under-voltage condition detected. | Wait for voltage to stabilize. Device should automatically reset after delay. If problem persists, consult an electrician to check line voltage. |
| Device does not reset after voltage stabilizes. | Internal fault or severe voltage fluctuation. | Disconnect power, wait a few minutes, then restore. If issue persists, contact support. |
| Loose connections or overheating. | Improper wiring. | Disconnect power immediately. Re-tighten all terminal screws. If damage occurred, replace the device. |
