6. Întreținere

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

• Păstrați aparatul curat și ferit de praf și resturi.
• Periodically inspect wiring connections for tightness and signs of wear.
• Asigurați o ventilație adecvată în jurul dispozitivului pentru a preveni supraîncălzirea.

7. Depanare

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

• Fără afișaj/Fără alimentare: 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.
• Phase Failure: The device automatically detects and responds to phase failures, initiating a cut-off and auto-reset once the phase is restored.
• Citiri incorecte: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
