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 Montaje
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).
- Asegúrese de que todas las conexiones estén firmes y seguras para evitar contactos sueltos y sobrecalentamiento.

7. Solución de problemas
This section provides guidance on common issues you might encounter with the STVP-932.
| Problema | Posible causa | Solución |
|---|---|---|
| El dispositivo se dispara con frecuencia | Volumentage 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. |
| Sin pantalla/Sin energía | 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. |
| Volumen incorrectotaglecturas electrónicas | Conexiones sueltas, problema del sensor. | Verify all wiring connections are secure. If the issue persists, contact support. |
8. Mantenimiento
- Regularly inspect the device for any physical damage or signs of overheating.
- Mantenga el dispositivo limpio y libre de polvo y residuos. Utilice un paño seco y suave para limpiarlo.
- Revise periódicamente todas las conexiones del cableado para asegurarse de que permanezcan firmes y seguras.

9. Consejos para el usuario
Based on common usage and feedback, here are some tips for optimizing your experience with the STVP-932:
- Configuración inicial: When first installing, set the protection values slightly wider than your expected normal operating range to avoid nuisance tripping, then fine-tune as needed.
- Escucha: Regularly check the digital display to understand the typical voltage behavior of your system, which can help in setting optimal protection parameters.
- Retraso de recuperación: Utilize the fault recovery delay time setting to prevent rapid on/off cycling of equipment during intermittent power issues, protecting sensitive loads.
