Danger to life due to electric shock
Overvoltages (e. g. in the case of a flash of lightning) can be further conducted into the building
and to other connected devices in the same network via network cables or other data cables if
there is no overvoltage protection.
• Ensure that all devices in the same network and the battery are integrated in the existing
overvoltage protection.
• When laying the network cables or other data cables outdoors, attention must be given to
suitable overvoltage protection at the cable transition from the inverter or the battery
outdoors to the inside of a building.
Failure-free operation of all system components due to tethered connection
• To ensure failure-free operation, SMA Solar Technology AG recommends connecting all
