Installing Overvoltage Protection for Ethernet
Communication
The network cables for the Ethernet communication are routed from SMA String-Monitor to SMA
String-Monitor up to the inverter. An overvoltage protection unit is needed in the SMA String-
Monitor for each Ethernet communication output and input.
The Ethernet cables are connected to LSA+ terminals on the electronic assembly using an LSA+
insertion tool.
Interference in data transmission due to unshielded power cables
If unshielded power cables are used, they generate an electromagnetic field during operation
which may induce interference in network cables during data transmission.
• When laying network cables, observe the following minimum clearances to unshielded
energy cables:
– For installation without separating strip: at least 200 mm
– For installation with aluminum separating strip: at least 100 mm
– For installation with steel separating strip: at least 50 mm
Requirements for Ethernet cables:
☐ Cable type: copper, two-conductor
☐ Number of insulated conductor pairs and insulated conductor cross-section: 4 x 2 x 0.125 mm
2
to 0.205 mm

☐ Cable type: at least Cat5 with shielding S-UTP, F-UTP or higher
☐ Maximum cable length: 100 m
☐ The RJ45 connectors must be connected in accordance with EIA/TIA 568B (eight-conductor):
