Danger to life due to electric shock when live components or cables of the
inverter are touched
High voltages are present in the conductive components or cables of the inverter. Touching live
parts and cables of the inverter results in death or lethal injuries due to electric shock.
• Disconnect the product and battery from voltage sources and make sure it cannot be
reconnected before working on the device.
• Wear suitable personal protective equipment for all work on the product.
• Do not touch non-insulated parts or cables.
Danger to life due to electric shock when live components or DC cables are
touched
The DC cables connected to a battery may be live. Touching live DC cables 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.
• Wait five minutes before working on the inverter.
• Observe all safety information of the battery manufacturer.
• 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.
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 product is classified as "TNV-1" and offers protection against
overvoltages of up to 1.5 kV.
