clients Inverters with Fronius Datamanager, Fronius Com Card, DATCOM components with ex-
ternal housing, or other DATCOM components will hereinafter be referred to as Fronius
Solar Net clients.
Fronius Solar Net
Client Cabling The data connection for the Fronius Solar Net client is a 1:1 connection using 8-pin data
cables and RJ-45 plugs.
The overall line length in a Fronius Solar Net ring must not exceed 1000 m.
Requirements for
the Fronius 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!
Permitted cables:
- S/STP
- F/STP
- S/FTP
- F/FTP
- SF/FTP
- S/UTP
- F/UTP
- U/FTP
- U/STP
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
twisted pairs of wires are assigned correctly for cabling in accordance with TIA/
EIA-568B:

- Make sure that the wires are assigned correctly.
- When setting up an independent ground connection (e.g., in patch panels), make
sure that the shield is grounded on one side of the cable only.
