6. Mantemento

The EARU-1008 is designed for minimal maintenance. However, periodic checks are recommended:

• Manteña o dispositivo limpo e libre de po e restos.
• Periodically inspect wiring connections for tightness and signs of wear.
• Asegúrese de que haxa unha ventilación axeitada arredor do dispositivo para evitar o sobrequecemento.

7 Solución de problemas

If the device is not functioning as expected, consider the following:

• Sen pantalla/Sen alimentación: Check the main power supply and all wiring connections.
• Protection Trip: Identify the active protection indicator (>V, <V, >I). Check the corresponding voltage or current levels. The device will automatically reset once conditions return to normal, based on configured recovery delays.
• Fallo de fase: The device automatically detects and responds to phase failures, initiating a cut-off and auto-reset once the phase is restored.
• Lecturas incorrectas: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
