2.2.4. Warning of Electric Shock
2.2.5. Warning of Overvoltages
2.2.6. Caution of Weight
Observe all safety information of the manufacturer.

Danger to life due to electric shock when live components or DC cables are touched
The DC cables connected to an inverter may be live. Touching live DC cables results in death or
serious injury due to electric shock.
• Disconnect the battery system and inverter from voltage sources and make sure it cannot
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 battery system.
•
Observe all safety information of the inverter manufacturer.
DANGER
Danger to life due to electric shock in case of overvoltages and if surge protection is missing
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. Touching live parts and cables results in death or
lethal injuries due to electric shock.
• Ensure that all devices in the same network and the inverter are integrated into the
existing surge protection.
• When laying the network cables or other data cables outdoors, it must be ensured that a
suitable surge protection device is provided at the transition point of the cable from the
battery system or the inverter outdoors to the inside of a building.
• The Ethernet of the inverter is classified as "TNV.1" and offers protection against
overvoltage of up to 1.5kV.
DANGER
CAUTION
Risk of injury due to
the weight of the battery module
Injuries may occur if the battery module is lifted incorrectly or dropped while being transported
or installed.
• Transport and lift the battery module carefully. Take the weight of the battery module into
account.
• Wear suitable personal protective equipment for all work on the battery system.

2.2.7. Notice of Property Damage
NOTICE
NOTICE
Damage to the battery system due to under voltages
•If the battery system doesn't start at all, please contact BYD's local after-sales
service team
within 48 hours. Otherwise, the battery could be permanently damaged.
Damage to the BCU due to sand, dust and moisture ingress
Sand, dust and moisture penetration can damage the BCU and impair its functionality.
•Only open the BCU if the humidity is within the thresholds and the environment is free of
sand and dust.
