Connecting The Communication With The Sma Cluster Controller Or Sma Inverter Manager - SMA FUEL SAVE CONTROLLER 2.0 Instrucciones De Instalación

6 Electrical Connection
Interference of network data transmission due to AC cables
When AC cables are in operation, they generate an electromagnetic field which may induce leading or lagging
interference in network cables during data transmission.
• Lay the network cables using suitable fastening material while observing a minimum clearance of 50 mm to
the AC cables.
Cable requirements:
☐ Conductor cross-section: at least 2 x 2 x 0.22 mm
☐ Cable type: 100BaseTx, at least CAT5e with shielding S/FTP, F/FTP or higher
☐ Cable length for installation cable: maximum 100 m
☐ Cable length for patch cable: maximum 50 m
☐ Cables to be laid outdoors must be UV-resistant or routed in a UV-resistant cable channel.
☐ Type of plug: RJ45
☐ RJ45 plugs used for installation cables must have a metal enclosure. The cable shield must be connected on both
ends of the installation cable.
Requirement:
☐ The requirements for the internal communication network of the PV diesel hybrid system must be observed (see
Section 6.8.1, page 35).
Procedure:
1. Insert the cable into the Fuel Save Controller (see Section 9.1, page 47).
2. Connect the cable to the router K201 at the pin connectors X7, X8 or X9.
6.8.5 Connecting the Communication with the SMA Cluster Controller or SMA
Inverter Manager
If there are temperature or irradiation sensors connected to an SMA Cluster Controller or to an SMA Inverter Manager
in the PV diesel hybrid system, you can also have the Fuel Save Controller analyze the data obtained by the
temperature and the irradiation sensors. To do this, you must connect the Fuel Save Controller with the Ethernet
communication interface of the SMA Cluster Controller or of the SMA Inverter Manager.
When you connect the Fuel‫ ؘ‬Save Controller with the Ethernet communication interface of the SMA Cluster Controller
or of the SMA Inverter Manager, always connect the RJ45 network cable as follows.
