The communication interfaceSMA Solar Technology AG8 The communication interfaceThe communication interface is used for communication with special data acquisition devices or a PCwith corresponding software.See the communication interface documentation for a detailed wiring diagram.This section describes how to install the communication module in the Sunny Boy.Installation procedureThe letters in brackets refer to the figure on the next page.1. Open the Sunny Boy as described in Section 6.2 .WARNING!Electrostatic discharges can damage the communication interface!• Do not touch components connections and plug contacts.• Ground yourself before removing the communication interface from the packagingby touching the PE or a non-coated part of the housing.2. Thread the cable through one of the cable feed-throughs (A) on the Sunny Boy. Use the righthandhousing feed-through for the Radio Piggy-Back.WARNING!Danger to life through high voltage if there is a fault with the communicationcable.• Pull the silicone tube over the cable.The silicon tube must completely cover the communication cable inside the housing.3. If the connection plan of the communication device indicates it as necessary:– ground the communication cable at the tab (C) or– use the provided cable shield on its screwing device (F) for the communication interface.4. Install the communication cable (B) as described in the following figure.5. Connect the communication wires to the screw terminal strip (D) as described in the connectionplan of the communication device.6. Connect the jumpers (E) if the connection plan of the communication device indicates this asnecessary.A detailed description of the jumper functions can be found in the communication devicemanual.7. Plug the communication interface to the left of the interface port (F).8. Close the Sunny Boy as described in section 6.3 .40 SB25_30-IEN083212 Installation Guide
