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 inverter is classified as "TNV-1" and offers protection against
overvoltages of up to 1.5 kV.
Additionally required material (not included in the scope of delivery):
• One to two network cables
• Where required: Field-assembly RJ45 connector.
• If cables are routed in a conduit: conduit (trade size: 21 mm (0.75 in) or smaller with suitable
reducer bush)
• If cables are routed in a conduit: UL-listed raintight or liquidtight conduit fitting (trade size:
21 mm (0.75 in) or smaller with suitable reducer bush)
• If cables are used for outdoors: one waterproof cable gland
Network cable requirements:
The cable length and quality affect the quality of the signal. Observe the following cable
requirements.
☐ Cable type: 100BaseTx
☐ Cable category: Cat5, Cat5e or higher
☐ Plug type: RJ45 of Cat5, Cat5e or higher
☐ Shielding: SF/UTP, S/UTP, SF/FTP or S/FTP
☐ Number of insulated conductor pairs and insulated conductor cross-section: at least 2 x 2 x
0.22 mm² (2 x 2 x 24 AWG)
☐ Maximum cable length between two nodes when using patch cables: 50 m (164 ft)
☐ Maximum cable length between two nodes when using installation cables: 100 m (328 ft)
☐ UV-resistant for outdoor use
