5. Installation and Wiring
Proper installation is crucial for the safe and correct operation of the device. It is recommended that installation be carried out by a qualified electrician.
Installation Steps:
- Power Off: Before any installation, ensure the main power supply to the circuit is completely disconnected.
- Mounting: Mount the device onto a standard DIN rail in your electrical distribution box.
- Wiring: Connect the input and output wires according to the diagram below. Ensure all connections are tight and secure.
- Input: Connect the incoming Neutral (N) and Live (L) wires to the 'N IN L' terminals.
- Output: Connect the outgoing Neutral (N) and Live (L) wires to the 'N OUT L' terminals.
- Important: This device is designed to interrupt the Live (L) line only. Ensure correct polarity.
- Power On: Once wiring is complete and checked, restore power to the main circuit. The device display should light up.
6. Operation
Manual Control:
- Switch ON/OFF: Press the circular power button on the front panel to manually turn the circuit on or off.
- View Data: The LED display will show real-time values for Voltage (V), Ampere (A), Leakage (mA), and total Kilowatt-hours (kWh).
Setting Parameters (Manual):
You can adjust various protection parameters directly on the device. Long press the 'SET' button for 5 seconds to enter the setting mode. Use the Up/Down arrow keys to navigate through parameters and adjust values. Press 'SET' again to confirm and move to the next parameter. Press 'WIFI/PULSE' to save and exit settings.

- Overcurrent Protection: If electrical appliances use too much electricity, the device will cut off power in approximately 0.1 seconds. It is self-recovering. Check for overloaded circuits or faulty appliances.
- Leakage Protection: If a leakage fault occurs, power will be cut off. The device will restart once the fault disappears. Identify and fix the source of the leakage.
- Over/Under Voltage Protection: If voltage is too high or too low, the device will cut off power and wait for voltage to return to stability before reconnecting. Check your power supply for voltage fluctuations.
- Review and adjust protection threshold settings (refer to Section 6 or App Control).
- WIFI Model (TOMPD-63SW) Not Connecting to App:
- Ensure your Wi-Fi network is 2.4Ghz (5Ghz is not supported).
- Check Wi-Fi signal strength at the device location.
- Restart your Wi-Fi router and the device.
