Connecting the Network Cables

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 the network cable if there is no
overvoltage protection.
• Ensure that all devices in the same network are integrated in the existing overvoltage
protection.
• When laying the network cable outdoors, attention must be given to suitable overvoltage
protection at the network cable transition from the inverter outdoors to the network inside the
building.
• The Ethernet interface of the inverter is classified as "TNV-1" and offers protection against
overvoltages up to 1.5 kV.
Additionally required material (not included in the scope of delivery):
• Conduits: 27 mm (1 in) or smaller with a proper reducing bush
• Rain-tight conduit fitting for wet locations complying with UL 514B: 27 mm (1 in) or smaller
with a proper reducing bush
• Network cable
• Where required: Field-assembly RJ45 connector.
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, Cat6, Cat6a or Cat7
☐ Plug type: RJ45 of Cat5, Cat5e, Cat6 or Cat6a
