Connecting the Network Cables
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.
Product damage due to moisture penetration
Moisture penetration can damage the product and impair its functionality of the product.
• Connect the network cable with the supplied RJ45 protective sleeve to the product.
