- Check if there is any sign of short circuit in the BICs (e.g. component damage - what is
the BIC part is shown in section 3.3)
- Check the sampling cables connection: B2+ up left / B1+ bottom left / B2- up right / B1-
bottom right
- Check whether the LED lights on the two BIC (electric components directly on the two
battery modules inside LVL - see section 3.3) are on.
If yes, try to exchange the upper BIC with the lower one.
If not, BIC replacement might be needed.
- Download all data with BCP (especially the cell data) (section 2.5)
- Measure the cell voltage according to section 2.6
- Check if the system works when removing the LVL with the EC (see section 2.8)
- provide the SN and voltage of the LVL with the EC (see checklist on last page)

Undervoltage
- Shut down the system quickly to avoid further discharge. Check whether the system can
shut down normally (by pressing the LED button in BMU for 5s).
- Follow section 2.6 (Voltage measurement of cells)

- Download all data with BCP (especially the historical and cell data) (section 2.5)
- Check the voltage of the batteries according to section 2.6
- Check if the system works when removing the module with the EC (see section 2.8)
- provide the SN and voltage of the module with the EC (see checklist on last page)

- Make sure the inverter is on, configured and working correctly.
- Check according to section 2.2
