5. Instalación
Advertencia: Ensure all power is disconnected before proceeding with installation. Installation must be performed by a qualified electrician.
5.1 Montaje
The TOMZN TOQ7e ATS is designed for DIN rail mounting.
- Select a suitable location within your electrical panel or enclosure that provides adequate ventilation and protection from environmental factors.
- Attach the ATS securely to a standard DIN rail by engaging the mounting clip at the bottom of the device.

5.2 Cableado
Follow the wiring diagram provided with your specific product variant or consult a qualified electrician. The general wiring principle involves connecting Source A (City Power), Source B (Generator), and the Load to their respective terminals.
- Source A (City Power): Connect the main utility power lines to the 'Source A' input terminals.
- Source B (Generator/Secondary Power): Connect the generator or secondary power lines to the 'Source B' input terminals.
- Carga: Connect the electrical circuits or appliances you wish to power to the 'Load' output terminals.
- Ensure correct phase and neutral connections.
- Tighten all screw terminals firmly to prevent loose connections and potential hazards.
6. Instrucciones de funcionamiento
6.1 Operación manual
The ATS can be manually switched between power sources using the selector switch on the front panel.
- Ensure the selector switch is in the 'Manual' position.
- Rotate the switch to select either 'Source A' or 'Source B' to supply power to the load.
- Observe the indicator lights to confirm the active power source.
6.2 Operación automática
For automatic power transfer, set the selector switch to the 'Auto' position.
- When 'Source A' (City Power) is available, the ATS will automatically connect the load to Source A.
- If 'Source A' fails, the ATS will detect the outage and, after a pre-set delay, automatically switch the load to 'Source B' (Generator), provided Source B is available and stable.
- When 'Source A' is restored, the ATS will automatically switch the load back to Source A after a pre-set delay.
- Indicator lights will show the status of each source and which source is currently supplying power.
6.3 WiFi Connectivity and EWelink App
The TOMZN TOQ7e integrates with the EWelink app for remote monitoring and control.
- Download EWelink App: Download the EWelink app from your smartphone's app store (iOS or Android).
- Registrarse/Iniciar sesión: Create an account or log in to your existing EWelink account.
- Agregar dispositivo: Follow the in-app instructions to add a new device. This typically involves putting the ATS into pairing mode (refer to the device's specific pairing instructions, usually by pressing and holding a button) and connecting to your home WiFi network.
- Control y monitoreo remoto: Once connected, you can monitor the status of both power sources, view current power usage (if supported by the specific model), and remotely switch between manual and auto modes, or even trigger a manual transfer.
- Funciones del temporizador: Utilize the app's timer features to schedule power transfers or monitor events.
7. Mantenimiento
El mantenimiento regular garantiza la longevidad y el funcionamiento confiable de su ATS.
- Inspección periódica: Annually inspect the device for any signs of physical damage, loose connections, or discoloration.
- Limpieza: Mantenga el dispositivo libre de polvo y residuos. Utilice un paño seco y suave para limpiarlo. No utilice limpiadores líquidos.
- Estanqueidad del terminal: Periodically check and re-tighten all screw terminals to ensure secure electrical connections.
- Prueba de funcionalidad: Pruebe periódicamente la función de transferencia automática simulando un corte de energía.tage (e.g., by temporarily disconnecting Source A, if safe to do so and with proper precautions).
8. Solución de problemas
If you encounter issues with your TOMZN TOQ7e ATS, refer to the following troubleshooting guide:
| Problema | Posible causa | Solución |
|---|---|---|
| Device not switching automatically | Selector switch in 'Manual' position. One or both power sources unavailable/unstable. | Set selector to 'Auto'. Check power supply to Source A and Source B. Ensure generator is running and stable. |
| No power output to load | No active power source. Overload or short circuit tripped internal protection. Loose wiring. | Verify both Source A and Source B are active. Check for tripped circuit breakers upstream. Inspect and tighten all wiring connections. |
| Problemas de conexión WiFi | Incorrect WiFi password. Device too far from router. Router issues. | Ensure correct WiFi password. Move device closer to router or use a WiFi extender. Restart router. Re-attempt pairing process. |
| Las luces indicadoras no funcionan | No power to the device. Faulty unit. | Check power supply. If power is present and lights are still off, contact support. |
Si el problema persiste después de intentar estas soluciones, comuníquese con el servicio de atención al cliente o con un electricista calificado.
