Connecting The Communication With The Inverters Via Optical Fibers - 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 X5 or X6.

Connecting the Communication with the Inverters via Optical Fibers

The communication of the Fuel Save Controller with the inverters in the PV power plant and the optional memory
system takes place via the internal communication network of the PV diesel hybrid system. If an increased exposure
due to electromagnetic interferences is to be expected for the internal communication network of the PV diesel hybrid
system, the use of optical fibers is recommended. The optical fiber terminal is however optional and is not available in
the basic configuration of the Fuel Save Controller.
Eye Injuries due to laser light
In optical fibers, laser light is used for data transmission. Direct incident laser light may damage the eye and can
lead to permanent retina damage.
• Never look directly into optical-fiber terminals or connected optical fibers.
• Ensure that the optical fiber is not connected to any active source before performing any work. To do this,
disconnect the connected devices.
• Always seal unused pin connectors or plugs with protective caps.
Damage to optical fibers due to too tight bend radii
Excessive bending or kinking will damage the optical fibers.
• Observe the minimum permissible bend radii of the optical fibers.
Cable requirements:
☐ Maximum cable length: 2 km
