CAUTION
DANGER
DANGER

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 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.
Risk of injury due to weight of the battery module
Injuries may result 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.
