12 The communications interface
The communications interface is used to communicate with SMA communication
devices (e. g. Sunny Boy Control, Sunny WebBox) or a PC with appropriate software
(e. g. Sunny Data Control). Depending on the selected communications interface, up
to 2500 inverters can be interconnected. Detailed information on this topic can be
found in the communication device manual, the software, or on the Internet at
www.SMA.de .
The detailed wiring diagram for the individual communications interfaces can be found
in the communication device manual. This wiring diagram includes:
•
Specifications of the necessary cable type
• Which of the inverter's connections are used
• Whether jumpers need to be mounted, and if so, which jumpers
• Whether the PE needs to be connected to the cable shield
The next pages will describe the following:
•
The enclosure feed-throughs for the communications interface
• The permitted cable route in the Sunny Boy
• The location of the PE connector
• The location of the screw terminals for connection of communication wires
• The location of the jumper slots
• The location of the interface port
Attention!
Installation or replacement of the communications interface is only to be
carried out by a trained electrician.
