5. Setup
5.1. Installation
The SVP716-110V is designed for DIN rail mounting. Ensure the DIN rail is securely installed in a suitable electrical enclosure.
- Mount the device onto a standard 35mm DIN rail by clipping it into place.
- Ensure adequate ventilation around the device.
5.2. Wiring Diagram
Connect the device according to the following wiring diagram. Ensure all connections are tight and secure.
- IN (N): Connect the Neutral wire from the power source to the 'N' input terminal.
- IN (L): Connect the Live wire from the power source to the 'L' input terminal.
- OUT (N): Connect the Neutral wire to your load from the 'N' output terminal.
- OUT (L): Connect the Live wire to your load from the 'L' output terminal.
Important: Always verify correct polarity (Neutral and Live) to ensure proper device function and safety.
6. Operating Instructions
6.1. Initial Power On
Once wired correctly, apply power to the device. The dual LED displays will light up, showing the current voltage and current values. The 'POWER' indicator will be lit.
6.2. Setting Protection Parameters
The SVP716-110V allows you to customize various protection thresholds and timings. The settings are retained even after power disconnection.
- Enter Setting Mode: Press and hold the
SETbutton for approximately 5 seconds until the display starts flashing, indicating you are in setting mode. - Navigate Settings: Press the
SETbutton briefly to cycle through the different adjustable parameters (Over-voltage, Under-voltage, Over-current, Protection setting time, Recovery delay time, Continuous over-current protection times). - Adjust Values: Use the
UP (Triangle Up)andDOWN (Triangle Down)buttons to change the value of the currently selected parameter. Long-press these buttons for faster adjustment. - Save Settings: After adjusting all desired parameters, press and hold the
SETbutton for approximately 5 seconds to save the changes and exit the setting mode. The display will stop flashing. - Restore Factory Defaults: To reset all settings to their factory default values, press and hold the
SET,UP, andDOWNbuttons simultaneously for 5 seconds.
Adjustable Parameters (120VAC Version Defaults):
- Over-voltage Protection (OV): 130-150V (Default: 140V)
- Under-voltage Protection (UV): 70-105V (Default: 80V)
- Over-current Protection (OC): 1-40A, 1-63A, 1-80A (Default: 40A/63A/80A, depending on model variant)
- Protection Setting Time: 0.1-30 seconds (Default: 1 second) - Time before protection trips.
- Recovery Delay Time: 1-600 seconds (Default: 5 seconds) - Time before power is restored after a protection event.
- Continuous Over-current Protection Times: Adjustable (Default: 10) - Number of times overcurrent can occur before a longer lockout.
6.3. Manual ON/OFF
You can manually turn the power output ON or OFF using the power button:
- Turn OFF: Long press the
ON/OFF (Power Symbol)button to cut the power output to the load. The display will show 'OFF'. - Turn ON: Long press the
ON/OFF (Power Symbol)button again to restore power output.

7. Maintenance
- Cleaning: Periodically clean the device with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect the wiring connections for any signs of loosening or damage.
- Environment: Ensure the operating environment is free from excessive dust, moisture, and corrosive gases.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power supply; incorrect wiring. | Check power source. Verify wiring connections (N and L inputs). |
| Power output is OFF, but voltage/current is normal. | Device is in manual OFF state; protection triggered and not yet recovered. | Long press the ON/OFF button to manually turn it ON. Check if recovery delay time is still counting down. |
| Device frequently trips. | Protection parameters set too sensitive; unstable power supply; load issues. | Adjust protection thresholds (OV, UV, OC) to appropriate levels. Check power quality. Inspect connected load for faults. |
| Settings are not saved. | Did not exit setting mode correctly. | Ensure you long-press the SET button for 5 seconds to save and exit after making changes. |
| Display shows 'OFF' or 'Err'. | Manual OFF; internal error. | If 'OFF', long press ON/OFF button to restore. If 'Err', try resetting to factory defaults or contact support. |
9. User Tips
- Generator Protection: This device is highly effective for protecting sensitive equipment connected to generators, especially against voltage drops. Adjust the undervoltage protection and recovery delay time to suit your generator's characteristics and load requirements.
- Settings Retention: The device retains its programmed settings even after power is disconnected, eliminating the need for re-configuration after outages.
- Adjustable Parameters: Take advantage of the adjustable voltage and amperage settings to precisely match the protection needs of your specific devices.
- Micro Power Outages: The fast protection setting time (as low as 0.1 seconds) can help mitigate issues caused by micro power outages or rapid voltage fluctuations.
