2.2 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This section contains safety information that must be observed at all times when working on or with
the product.
The product has been designed and tested in accordance with international safety requirements. As
with all electrical or electronical devices, there are residual risks despite careful construction. To
prevent personal injury and property damage and to ensure long-term operation of the product,
read this section carefully and observe all safety information at all times.
DANGER
Danger to life due to electric shock when live components or DC conductors
are touched
The DC conductors connected to a battery may be live. Touching live DC conductors results in
death or serious injury due to electric shock.
• Disconnect the product and battery 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 product.
• Observe all safety information of the battery 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 battery 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
product or the battery outdoors to the inside of a building.
• The Ethernet interface of the inverter is classified as "TNV-1" and offers protection against
overvoltages of up to 1.5kV.
