5.3 Wiring Instructions

The GPS8-06 is designed for DIN rail mounting. Follow these steps for proper wiring:

1. Disconnect Power: Before starting any wiring, ensure the main power supply to the circuit is completely disconnected at the MCB.
2. Mount the Device: Securely mount the GPS8-06 onto a standard DIN rail in your electrical panel.
3. Connect Power Supply: Connect the incoming live (L) and neutral (N) wires to the 'IN' terminals of the device. Use appropriate wire gauges for your rated current.
4. Connect Load: Connect the outgoing live (L) and neutral (N) wires to the 'OUT' terminals of the device, leading to your electrical load (e.g., light bulb, appliance).
5. Verify Connections: Double-check all connections to ensure they are tight and correctly wired according to the markings on the device.

6. Operation

6.1 Power On/Off

After successful wiring, turn on the main electricity supply. The device's LCD display will light up, showing current voltage and other parameters. The power button () on the front panel can be used to manually turn the connected load on or off.

6.2 Display and Indicators

• LCD Display: Shows real-time values for voltage (V), current (A), power (W), and accumulated energy (kWh).
• LED Indicators:
  • >U (Red LED): Indicates overvoltage condition.
  • <U (Red LED): Indicates undervoltage condition.
  • >I (Red LED): Indicates overcurrent condition.
  • WiFi (Blue LED): Indicates Wi-Fi connection status.

6.3 Button Functions

• 'M' Button: Short press to cycle through display modes (e.g., voltage, current, power, energy). Long press (3 seconds) to exit and save settings during parameter configuration.
• Up/Down Arrows (integrated with WiFi button): Short press to increase or decrease values during parameter setting. Long press for quick adjustment.
• Power Button: Manually switch the load on/off.

7. Wi-Fi Configuration and App Usage

To utilize the smart features, connect the device to your Wi-Fi network via the dedicated smartphone app (e.g., Tuya Smart or Smart Life app).

1. Download App: Scan the QR code on the product or search for "Tuya Smart" or "Smart Life" in your app store to download and install the app.
2. Enter Wi-Fi Configuration Mode: Press and hold the Wi-Fi button () for 5 seconds until the Wi-Fi indicator flashes rapidly. This indicates the device is ready for pairing.
3. Add Device in App: Open the app, click on "Add Device" or the '+' icon, and select the appropriate device type (e.g., "Electrical Switch" or "Circuit Breaker (Wi-Fi)").
4. Enter Wi-Fi Credentials: Follow the app's prompts to enter your home Wi-Fi network name (SSID) and password. Ensure your phone is connected to the same 2.4GHz Wi-Fi network.
5. Pairing: The app will attempt to connect to the device. The Wi-Fi indicator on the device will flash during pairing and become solid when successfully connected.
6. Access Device Settings: Once added, click "Finish" in the app. You can now access the product settings page within the app.
7. Remote Control: From the app, you can remotely turn the product on or off.
8. Scheduling: Set fixed times for the product to turn on or off automatically.
9. Monitoring: View real-time voltage, current, power, and energy consumption data.

8. Setting Protection Parameters

The GPS8-06 allows you to set custom thresholds for overvoltage, undervoltage, and overcurrent protection. These settings can typically be adjusted via the device's physical buttons or through the smartphone app.

8.1 Adjusting Values via Device Buttons

To adjust parameters directly on the device:

1. Press the 'M' button to enter the setting mode.
2. Use the Up/Down arrow buttons (often integrated with the Wi-Fi button) to increase or decrease the displayed value. A short press changes the value incrementally, while a long press allows for quicker adjustments.
3. If no key is operated for 60 seconds, the device will automatically exit the setting mode.
4. To manually exit and save settings at any time, press and hold the 'M' button for 3 seconds.

8.2 Available Settings

• Overvoltage (OV) Threshold: Set the maximum voltage limit (e.g., 230V-300V or OFF). If the voltage exceeds this, the device will trip.
• Undervoltage (UV) Threshold: Set the minimum voltage limit (e.g., 140V-210V or OFF). If the voltage drops below this, the device will trip.
• Overcurrent (OC) Threshold: Set the maximum current limit (e.g., 32A, 40A, 63A, 80A depending on model). If the current exceeds this, the device will trip.
• Power Up Delay: Time delay before the device powers on after a power restoration or manual switch-on (2s-600s).
• Reset Time: Time delay before the device attempts to self-reset after a fault trip (2s-900s).

9. Troubleshooting

10. User Tips

• Wiring Neutral: Ensure the neutral wire is correctly connected through the device. The device typically requires the neutral to be passed through for proper operation and measurement.
• Current Limit Precision: The current limit setting step is usually 1A for these devices. Refer to the technical specifications for exact precision.
• Energy Monitoring: This device provides real-time energy consumption (kWh) monitoring but does not support prepaid energy functions or bidirectional metering for grid export.
• Remote Monitoring: For worldwide monitoring, ensure your smartphone has internet access and the device is successfully connected to your home Wi-Fi network, which in turn has internet access.

11. Maintenance

• Regular Inspection: Periodically check the device and its wiring for any signs of damage, loose connections, or overheating.
• Cleaning: Clean the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents.
• Firmware Updates: Check the smartphone app periodically for any available firmware updates for the device to ensure optimal performance and security.
• Power Disconnection: Always disconnect the main power supply before performing any physical maintenance on the device or its connections.
