Danger due to electrical energy
DANGER
There is a risk of electric shock when touching parts that are under
voltage. This also poses a danger of secondary accidents as a result
of shock (e.g. falls).
–
Keep electrical components closed at all times.
–
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.
–
Adhere to the five safety rules when working on the electrical equipment:
1. Disconnect
2. Secure against being switched back on
3. Verify that the system is de-energised
4. Connect to earth and short circuit
5. Cover or partition off live parts
In order to ensure the safe performance of electrical work, the operating company
can transfer its obligations over to a system manager (specialised electrician).
The transfer of responsibility must be made in writing.
–
Before working on the electrical equipment, de-energise the battery storage system
and secure it against re-activation.
DANGER
There is a risk of electric shock when touching parts that are under
voltage.
Because the system contains batteries that cannot be de-energised,
life-threatening DC voltages are always present in some sub-areas of
the system.
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 battery modules cannot be de-energised. There is always
dangerous electrical voltage at the power connections on the battery
modules and at the connections B+ and B- on the battery management
system.
