cables and RJ-45 plugs.
The overall line length in a Fronius Solar Net ring must not exceed 1000 m.
Requirements for
the Solar Net Data
Cables Shielded CAT5 (new) and CAT5e (old) cables compliant with ISO 11801 and EN 50173
must be used for the Fronius Solar Net client cabling. Other cables are not permitted.
IMPORTANT! Do not use ISO/IEC-11801 U/UTP cables!
The shield must be crimped onto a CAT5-compatible shielded plug.
Due to the fact that the wires in Ethernet cables are twisted, you must make sure the twist-
ed pairs of wires are assigned correctly for cabling in accordance with TIA/EIA-568B:
