4. Installation and Setup
4.1 Mounting
The TOVPD1-63-VA is designed for 35mm standard DIN rail installation. Ensure the rail is securely mounted in your electrical panel. The installation and disassembly process is simple and convenient.
4.2 Wiring
Connect the device according to the wiring diagram below. The input (IN) terminals are for the incoming power line (L and N), and the output (OUT) terminals connect to the load. When connecting the power line, ensure to screw down to penetrate the insulating layer of the power lines for a secure connection. The wiring configuration is "Over-entering down-out".
Ensure all connections are tight and secure to prevent loose contacts and potential hazards.
5. Operation
Once correctly installed and powered on, the device will display the real-time voltage and current. The green POWER indicator will illuminate. If an over-voltage, under-voltage, or over-current condition occurs, the corresponding red LED indicator will light up, and the device will automatically cut off the power supply to protect connected appliances. After the fault condition is resolved and the system returns to normal parameters, the device will automatically restore power after the set recovery delay time.
6. Product Settings
The device allows for adjustment of various protection parameters. Use the "SET" button to enter and exit the setting mode, and the "Up" and "Down" arrow keys to navigate and change values. Press "SET" again to confirm a value and move to the next setting.

To exit settings, press the SET key after adjusting the last parameter (A12 or A13).
7. Maintenance
The TOMZN TOVPD1-63-VA is designed for long-term, maintenance-free operation. However, periodic checks are recommended:
- Ensure the device and its connections are clean and free from dust or debris.
- Verify that all wiring connections remain tight and secure.
- Check the display for proper functionality and accurate readings.
- In case of frequent tripping, investigate the cause in your electrical system rather than adjusting protection values excessively.
8. Troubleshooting
If the device is not functioning as expected, consider the following:
- No Display/No Power: Check the incoming power supply and wiring connections. Ensure the device is receiving 230VAC.
- Frequent Tripping: Review your set protection values (over-voltage, under-voltage, over-current) against your actual electrical load and supply stability. High sensitivity settings or unstable power can cause frequent trips.
- Incorrect Readings: If voltage or current readings appear inaccurate, use the A13 voltage calibration setting to adjust the voltage. For current, ensure the load is within the device's rated capacity.
- Device Not Recovering: Check the recovery delay time settings (A4, A8, A11). Ensure the fault condition has genuinely cleared.

10. User Tips
- Understanding Action Time: The "Action time" (A5, A9, A12) refers to how quickly the device will cut off power once a fault condition is detected. A shorter time provides faster protection but might lead to nuisance tripping in very unstable power environments. A longer time offers more tolerance but slightly delayed protection. Adjust this based on the sensitivity of your connected appliances and the stability of your power supply.
- Voltage Calibration (A13): If you have a calibrated multimeter and notice a discrepancy in the voltage displayed by the protector, use the A13 setting to fine-tune the reading for accuracy.
