There is a risk of electric shock when touching parts that are under
voltage.
The battery storage system can only be de-energised up to the battery
management system (connections P+ and P-) on the mains side. The
individual lithium-ion batteries cannot be de-energised. There is always
dangerous electrical voltage at the power connections on the lithium-ion
batteries and at the connections B+ and B- on the battery management
system.
–
Only ever have work on the electrical equipment performed by
specialised electricians with WLE certification and who have been
specifically trained for working on electrical equipment and who are
capable of recognising and avoiding dangers.
