Warning of electric shock

It is a danger to life due to electric shock when live components or DC cables are touched.
The DC cables connected to the system may be live. Touching live DC cables results in death or serious injury due to electric shock.
Disconnect the battery from a voltage source and make sure it can not be reconnected before working on the device.
Do not touch non-insulated parts or cables.
Do not remove the terminal block with the connected DC conductors from the slot under load.
Wear suitable personal protective equipment for all work on the system.

Notice of property damage
If the battery system doesn’t start at all, please contact BYD authorized service partner within 48 hours. Otherwise, the battery could be permanently damaged. When the system is installed, it needs to be able to charge and discharge to avoid a deep discharge condition. After the installation, this needs to be checked once a month. If the battery system is not working normally, please get in contact with your local service partner. During the storage of the battery system, please mind the maximum storage time.

Surge protection
Overvoltages (e. g. in the event of a flash of lightning) can be further conducted into the building and
to other connected devices in the same network via the network cables or other data cables if there is no surge protection. Ensure that the system is integrated into the existing surge protection.
