If the battery is beeping, it might indicate a fault or communication issue. Please check if the number of battery modules matches the DIP configuration and ensure that the RS485 communication cables are connected correctly. After verifying these, perform a power-on sequence by pressing the POWER button first, then wait 10 seconds before pressing it again. The buzzer will only sound during the self-test for the specific fault. If the test is completed and the beeping persists, it's best to contact an installer for further assistance.
