5. Configuración e instalación
The STVP-932 is designed for DIN rail mounting within an electrical enclosure. Ensure proper ventilation and clearance around the device.
5.1 Montaxe
Attach the protector to a standard 35mm DIN rail by snapping the clips on the back of the device onto the rail. Ensure it is securely fastened.
5.2 Diagrama de cableado
Follow the wiring diagram carefully to connect the STVP-932 to your three-phase electrical system. The device has 'IN' terminals for incoming power (L1, L2, L3, N) and 'OUT' terminals for protected outgoing power (L1, L2, L3, N).
Pasos de conexión:
- Connect the incoming three-phase power supply (L1, L2, L3, N) to the 'IN' terminals of the STVP-932.
- Connect the 'OUT' terminals (L1, L2, L3, N) of the STVP-932 to the load or downstream circuit protection devices (e.g., air circuit breaker).
- Asegúrate de que todas as conexións estean ben axustadas e seguras para evitar contactos soltos e sobrequecemento.
6. Instrucións de funcionamento
6.1 Pantalla dixital
A pantalla dixital mostra o volume en tempo realtage readings for each phase (A, B, C). In normal operation, it cycles through these readings or displays the current status.
6.2 Configuración de parámetros

Adjustable parameters include:
- Sobrevoltage protection value (Uvo)
- Sobrevoltage valor de recuperación
- Sobrevoltagtempo de acción de protección electrónica
- Sub-voltage protection value (Uve)
- Sub-voltage valor de recuperación
- Sub-voltagtempo de acción de protección electrónica
- Trifásico voltage unbalance protection value
- Trifásico voltage unbalance protection action time
- Delay time after power-on
- Fault recovery delay time
6.3 Reset Mode Selection
The device supports different reset modes. Consult the English manual included in the package for detailed instructions on selecting the appropriate reset mode for your application.
6.4 Fault Inquiry and Factory Reset
The device allows for fault inquiry to review past protection events. A factory data reset option is also available to restore all parameters to their default settings.
7 Solución de problemas
This section provides guidance on common issues you might encounter with the STVP-932.
| Problema | Causa posible | Solución |
|---|---|---|
| Device trips frequently | Voltage fluctuations (over/under voltage), phase unbalance, incorrect settings. | Check power supply stability. Adjust protection thresholds (Uvo, Uve) and action times. Verify load balance across phases. |
| Sen pantalla/Sen alimentación | No input power, incorrect wiring, internal fault. | Ensure main power is on. Check input wiring (L1, L2, L3, N). If wiring is correct and power is present, contact support. |
| Device does not reset | Continuous fault condition, incorrect reset mode setting. | Ensure the fault condition has cleared. Check the configured reset mode and recovery delay time. |
| Vol. incorrectotage lecturas | Loose connections, sensor issue. | Verify all wiring connections are secure. If the issue persists, contact support. |
8. Mantemento
- Regularly inspect the device for any physical damage or signs of overheating.
- Manteña o dispositivo limpo e libre de po e residuos. Use un pano seco e suave para limpar.
- Comprobe periodicamente todas as conexións do cableado para asegurarse de que permanezan axustadas e seguras.
