SAFETY AND HANDLING INSTRUCTIONS

• Read this entire document before installing or operating the Backup Interface (also referred to as BUI). Failure to do so or to follow any of the instructions or warnings in this document can result in electrical shock, serious injury, or death, or may damage the Backup Interface and other property, it can also lead to warranty void.
• Do not discard this document! After installation, keep it adjacent to the Backup Interface for future reference!
• Before operating the Backup Interface and inverter, ensure that they are properly grounded. The Backup Interface and inverter must be connected to a grounded, metal, permanent wiring system, or an equipment-grounding conductor must be run with the circuit conductors and connected to the equipment grounding terminal or lead.
• Opening the Backup Interface and repairing or testing under power must be performed only by qualified service personnel familiar with the Backup Interface.

6. Backup system checkup

Note: Before you start, make sure you have the Inverter system operating and producing with battery at above 20%.
Checking the backup operation may cause 2-3 seconds of electricity supply failure to the loads before they are powered up again; if you have a load sensitive to such interruption, please disconnect it from the load backup section.

Make sure the loads are evenly distributed between phases and do not exceed your inverter rating per phase.

1. Make sure you have power from the grid and your inverter is working.
2. Before you start, check that the Battery SoC level is above 20%.
3. Make sure the Grid LED is ON and there is no fault detected. Turn OFF the main CB coming from the grid. Immediately after that, all home loads should shut down and the “On grid” LED should turn OFF.
4. Wait for a few seconds till all the home loads are powered up again, the LED marked as “Backup” should turn ON.
5. After a few minutes of stable operation, turn ON the main CB again.
