1. Introduzzjoni
The SINOTIMER SVP-912 is an adjustable overvoltage u undervoltage protective device designed for single-phase electrical equipment. It is primarily used in residential household boxes or distribution lines to safeguard electrical appliances from damage caused by abnormal voltage conditions. This device automatically cuts off the power supply when overvoltage jew undervoltage occurs and restores power once the voltage jerġa' lura għal-livelli normali.
2. Informazzjoni dwar is-Sigurtà
- L-installazzjoni u l-manutenzjoni għandhom isiru biss minn elettriċisti kwalifikati.
- Kun żgur li l-provvista ewlenija tal-enerġija hija skonnettjata qabel l-installazzjoni jew kwalunkwe xogħol ta' wajers.
- Verify that the device's specifications (voltage, current) match your electrical system requirements.
- Tħaddimx l-apparat b'idejn imxarrbin jew f'damp kundizzjonijiet.
- This device is for protection against voltage fluctuations; it does not protect against overcurrents unless integrated with an appropriate circuit breaker.

4. Installazzjoni
4.1 Immuntar
The SVP-912 is designed for standard 35mm Din Rail mounting. Ensure the Din Rail is securely fastened within an electrical enclosure or distribution box.
4.2 Dimensjonijiet
Refer to the diagram below for precise dimensions to ensure proper fit and clearance during installation.
4.3 Dijagramma tal-Wiring
Connect the SVP-912 according to the wiring diagram provided. Ensure correct polarity (Neutral 'N' and Live 'L') for both input (IN) and output (OUT) terminals. It is recommended to install the voltage protector in series with a power switch and an air circuit breaker for comprehensive protection.

5.2 Issettjar tal-Parametri
The device features 'SET', 'UP' (▲), 'DOWN' (▼), and 'ADJ' buttons for configuration. Specific instructions for adjusting each parameter (overvoltage/undervoltage thresholds, recovery times, delay times) are typically detailed in the full manufacturer's manual. Generally, the 'SET' button is used to enter the setting mode, 'UP' and 'DOWN' to adjust values, and 'ADJ' or 'SET' again to confirm and exit.
The LED display shows the current voltage. When an overvoltage jew undervoltage event occurs, the corresponding 'Over(V)' or 'Under(V)' indicator light will illuminate, and the device will cut off power.
6. Manutenzjoni
The SVP-912 is designed for low maintenance. Periodically inspect the device for any signs of physical damage, loose connections, or discoloration. Ensure the ventilation slots (if any) are free from dust and debris. Cleaning should be done with a dry, soft cloth. Do not use abrasive cleaners or solvents.
7 Issolvi l-problemi
- Apparat mhux mixgħul: Check input wiring (L and N terminals) and ensure the main power supply is active.
- Frequent tripping: Review your set overvoltage u undervoltage thresholds. They might be too sensitive for your power supply conditions. Adjust the recovery delay time if brief fluctuations are causing unnecessary trips.
- Vol mhux korretttage reading: Ivverifika l-input voltage with a multimeter to ensure the device's reading is accurate. If discrepancies persist, contact support.
- Device not resetting automatically: Check the 'Reset mode selection' settings. Ensure it is configured for automatic recovery if desired.

9. Għajnuniet għall-Utenti
- For optimal protection, set the overvoltage u undervoltage thresholds slightly outside your normal operating voltage range to avoid nuisance tripping while still providing effective safeguarding.
- Consider the recovery delay time carefully. A longer delay can prevent rapid on/off cycling during unstable power conditions, protecting sensitive equipment.
- Regularly check the LED display to monitor your line voltage and ensure it remains within safe operating parameters.
