4. Sikkerhedsoplysninger

Adherence to safety guidelines is paramount when installing and operating electrical devices. Failure to follow these instructions may result in electric shock, fire, or damage to the product and connected equipment.

• Fare for elektrisk stød: After the product is powered on, do not touch any live parts to avoid electric shock. Always ensure power is disconnected before performing any wiring or maintenance.
• Kortslutningsbeskyttelse: This product requires working in conjunction with micro-interrupts (circuit breakers) for short circuit protection. Without proper external short circuit protection, the device cannot provide load limiting protection if a short circuit occurs at the input or load end.
• Korrekt ledningsføring: Ensure all wiring is correct and secure. Incorrect wiring, especially of the neutral wire (N), can prevent the protector from functioning properly and may cause damage.
• Belastningskompatibilitet: Verify that the load current is less than the maximum current value of the product (63A). Mismatching load size can lead to product damage.

5. Installation og opsætning

Follow these steps carefully for correct installation of the Over Under Voltage Protector:

1. Tilslut terminaler: Connect the input and output terminals correctly according to the product markings. Ensure the load current is less than the current value of the product (e.g., 63A).
2. Tilslutning af neutral ledning: The neutral wire (N) must be connected correctly and reliably. Incorrect connection of the neutral wire will prevent the protector from functioning properly.
3. Pre-Power Check: Before connecting to the main power supply, carefully check all wiring. Verify that the wiring is correct, the load size matches the product's current rating, and all wiring screws are tightened. Failure to do so may damage the product.

6. Betjening

Once properly installed and powered on, the Walfront Over Under Voltage Protector will display real-time voltage and current values on its digital screen.

• Digital skærm: The device features a clear digital display that shows the working voltage (L1(V), L2(V), L3(V)) for each phase and the current value.
• Justerbare indstillinger: The protector allows for adjustment of over-voltage og under-bdtage thresholds, as well as delay time. Refer to the on-device labels for "设置" (Settings), "查询" (Query), "上调" (Up), "下调" (Down), and "开关" (Switch) buttons to configure these parameters. Specific adjustment procedures are typically detailed on the device itself or in supplementary quick-start guides.
• Automatisk beskyttelse: The device automatically disconnects the load when voltage or current exceeds the set limits, and automatically reconnects when conditions return to normal after the set delay time.

7. Vedligeholdelse

The Walfront Over Under Voltage Protector is designed for reliable operation with minimal maintenance. However, regular checks and adherence to safety protocols are recommended.

• Circuit Inspection: Due to the product's automatic reset function, if the device frequently connects and disconnects the load, immediately remove the load from electrical appliances and thoroughly check the circuit. Frequent overload connection and disconnection for prolonged periods can damage the product or the electrical circuit.
• Miljøforhold: Ensure the device is operated within its specified environmental conditions (temperature, humidity) to prevent malfunction.
• Rensning: Hold enheden ren og fri for støv. Brug en tør, blød klud til rengøring. Brug ikke flydende rengøringsmidler.

8. Fejlfinding

If you encounter issues with your Walfront Over Under Voltage Protector, consider the following common scenarios:

• Enheden tænder ikke:
  • Check the main power supply to ensure it is active.
  • Verify all wiring connections, especially the neutral wire (N), are secure and correct.
  • Ensure the load current does not exceed the product's rated capacity.
• Frequent Disconnection/Reconnection:
  • This indicates that the voltage or current is frequently fluctuating outside the set parameters.
  • Immediately disconnect the load and inspect the connected circuit for faults, overloads, or unstable power supply.
  • Juster overvolumentage/under-voltage thresholds or delay time if the fluctuations are within acceptable operational limits for your equipment but triggering the protector too often.
• No Protection Function:
  • Ensure the device is correctly wired and powered.
  • Confirm that external micro-interrupts (circuit breakers) are installed and functioning for short circuit protection, as this device relies on them for comprehensive protection.

Hvis problemerne fortsætter efter at have fulgt disse trin, skal du kontakte kundesupport.
