5. Installation
5.1 Mounting
The GPS8-02 is designed for Din Rail mounting (EN/IEC 60715). Simply clip the device onto a standard 35mm Din Rail in your electrical panel.
5.2 Wiring Diagram
Ensure correct wiring according to the diagrams below. The device supports both 'Uper Incoming Line' and 'Down Incoming Line' configurations. Connect the Neutral (N) and Live (L) wires as indicated.
NOTE: This product does not have an isolation function. Please disconnect the superior MCB during maintenance!!!
6. Operating Instructions
6.1 Initial Power-Up
Upon initial power-up, the device will perform a self-check and then display the current voltage and current readings. There may be a power-up delay (default 2s).
6.2 Setting Parameters
- Enter Setting Mode: Press and hold the 'M' button for 3 seconds to enter the setting mode.
- Navigate Parameters: Short press the 'M' button to cycle through different parameters (e.g., overvoltage value, undervoltage value, overcurrent value, delay times).
- Adjust Values: Use the '▲' button to increase the value of the selected parameter.
- Save Settings: After modifying a parameter, press and hold the 'M' button for 3 seconds to save the setting and exit the setting mode.
6.3 Manual Control
- Manual ON/OFF: After exiting the setting mode, the '▲' button can be used to manually turn on or off the load.
- Fault Reset: If the automatic fault reset function is turned off, the 'Power Symbol' button can be used for manual reset when a fault occurs.
6.4 Functions Diagram (Voltage/Current Recovery)
The device monitors voltage and current continuously. When a fault (over/under voltage, overcurrent) occurs, the device will trip. After the fault condition clears and the set reset time has elapsed, the device will automatically recover (if auto-reset is enabled). The functions diagram in Figure 4.1 illustrates this recovery cycle.
7. Maintenance
- Keep the device clean and free from dust and moisture.
- Periodically check all wiring connections to ensure they are tight and secure.
- Inspect the device for any signs of physical damage. If damage is found, replace the device immediately.
- As noted in the installation section, always disconnect the main power supply (superior MCB) before performing any maintenance or inspection on the device.
8. Troubleshooting
If you encounter issues with your GPS8-02 protector, consider the following:
- Device not powering on: Check the main power supply and ensure all connections are correct and secure.
- Device trips frequently: Review your set parameters (overvoltage, undervoltage, overcurrent values, and action delays). Ensure they are appropriate for your connected load and power supply stability.
- Incorrect voltage/current readings: Verify wiring connections. If readings are consistently inaccurate, the device may require replacement.
- Device does not reset after fault: Check if the automatic reset function is enabled in the settings. If not, a manual reset using the 'Power Symbol' button is required.
- Load does not turn on/off manually: Ensure you are out of the setting mode before attempting manual control with the '▲' button.
If problems persist after checking these points, contact customer support.
9. User Tips
- Parameter Adjustment: Take time to properly set the overvoltage, undervoltage, and overcurrent thresholds to match your specific electrical system and connected appliances. Incorrect settings can lead to nuisance tripping or insufficient protection.
- Delay Settings: Utilize the power-up delay and action delay settings to prevent tripping from momentary fluctuations or inrush currents from certain appliances.
- Wiring Verification: Double-check your wiring against the provided diagrams, especially the 'Uper Incoming Line' vs 'Down Incoming Line' configuration, to ensure proper functionality and safety.
