5.2 Cable Requirements and Information on Routing
The cable length and quality have an effect on the signal quality in the Speedwire network. Observe
the following information and cable requirements:
Cable requirements
☐ Cable length between two nodes: max. 100 m
☐ Cross-section: at least 2x2x0.22 mm
2
or at least 2x2 AWG 24
☐ Cable type: 100BaseTx, CAT5 with shielding S-UTP, F-UTP or higher
☐ UV-resistant for outdoor use
☐ Type of plug: RJ45
SMA Solar Technology AG recommends the following cable types:
• For outdoor use: SMA COMCAB-OUTxxx
• For indoor use: SMA COMCAB-INxxx
The cables are available in the lengths xxx = 100 m, 200 m, 500 m, 1,000 m
5.3 Connecting the Cable to the Communication Terminal
Requirement:
☐ For Italy: There must be an available network operator gateway with network connection for
telecontrol protocol IEC 61850.
Additionally required material (not included in the scope of delivery):
☐ 1 network cable (see Section 5.2)
☐ 4 bootlace ferrules
☐ 1 RJ45 connector
Disturbance of data transmission due to AC Cables
When AC cables are in operation, they generate an electromagnetic field which may induce
interference in network cables during data transmission.
• Lay the network cables using suitable fastening material and with a minimum clearance
of 50 mm to the AC cables.
Figures in this section
The work steps in this section are supported by figures of the inverter types SB 3300-11 and
SB 3800-11. The procedure for other inverter types is analogous (see Section 5.1).
