4 Installation
• Plug the RJ45 connector into the surge arrester at the terminal LINE IN.
• To connect the Ethernet cable to the next SMA String-Monitor in the communication bus,
plug the other end of the Ethernet cable into the surge arrester for the communication
input in the next SMA String-Monitor at the terminal LINE IN.
• To connect the Ethernet cable in the inverter, see inverter manual.
8. Connect the electronic assembly to the surge arrester for the communication input:
• Plug the RJ45 connector on the supplied Ethernet cable into the EQUIP terminal of the
surge arrester.
• Connect the other end of the Ethernet cable on the electronic assembly to the String-
Monitor Unit at terminal X9 according to the circuit diagram. Observe the prescribed
cable route.
• Attach the Ethernet cable in the SMA String-Monitor with the cable brackets.
• Push the mounting tie onto the bracket of
the DC load-break switch and secure the
Ethernet cable in position with the cable tie.
9. For the communication input, connect the surge arrester to the enclosure opening for
communication:
• Route the Ethernet cable for the communication input through enclosure opening for
communication into the SMA String-Monitor. To do this, pierce the membrane and push
the Ethernet cable through the membrane.
• Connect the RJ45 connector to the inserted end of the Ethernet cable in accordance with
EIA/TIA 568B (eight-conductor). Make sure that no pieces of cable are dropped into the
SMA String-Monitor.
• Route the Ethernet cable to the surge arrester in the cable channel according to the cable
route. To do this, remove the cover of the cable channel, lay the Ethernet cable inside and
reattach the cover.
• Plug the RJ45 connector into the surge arrester at the terminal LINE IN.
10. Remount the protective covers in the SMA String-Monitor.
11. Switch the SMA String-Monitor back on.
