4. Enstalasyon ak Enstalasyon

4.1. Monte

The EARU-1008 is designed for DIN rail mounting. Securely attach the device to a standard 35mm DIN rail within an electrical enclosure.

4.2. Koneksyon fil elektrik

Gade dyagram fil elektrik ki anba a pou koneksyon ki kòrèk yo. Asire w tout koneksyon yo byen sere epi byen izole.

1. Connect the incoming neutral (N) and phase lines (L1, L2, L3) to the 'IN' terminals.
2. Connect the outgoing neutral (N) and phase lines (L1, L2, L3) to the 'OUT' terminals.
3. Tcheke an doub tout koneksyon anvan ou aplike pouvwa.

6. Antretyen

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

• Kenbe aparèy la pwòp epi san pousyè ak debri.
• Detanzantan enspekte koneksyon fil elektrik yo pou wè si yo sere epi si gen siy usure.
• Asire w ke gen ase vantilasyon toutotou aparèy la pou anpeche l chofe twòp.

NAN. Depanaj

Si aparèy la pa fonksyone jan yo te prevwa a, konsidere bagay sa yo:

• Pa gen ekspozisyon/Pa gen kouran: 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.
• Lekti ki pa kòrèk: If readings appear inaccurate, consider performing a manual error calibration as described in Section 5.3.
