6. Održavanje

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

• Održavajte uređaj čistim i bez prašine i ostataka.
• Periodically inspect wiring connections for tightness and signs of wear.
• Osigurajte odgovarajuću ventilaciju oko uređaja kako biste spriječili pregrijavanje.

7. Otkrivanje problema

Ako uređaj ne funkcioniše kako se očekuje, razmotrite sljedeće:

• Nema prikaza/Nema napajanja: 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.
• Netačna očitanja: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
