12.1 Connection of the interface
1. Open the inverter as described in section 7.1.
2. Guide the PG screw fitting over the communication cable.
3. Thread the cable through the cable feed-throughs (A) on the Sunny Boy.
4. Screw the PG screw fitting onto the Sunny Boy.
5. Sheathe the cable inside the Sunny Boy using the silicon tube provided. The silicon
tube is imperative for safety reasons. The interface may not be commissioned
without this silicon tube (with the exception of the Sunny Beam Piggy-Back).
6. Lay the cable in area (B) as shown in the figure to the right.
7. Ground the cable shield at the PE connector (C) if the terminal connection diagram
of the communication device indicates this as necessary.
8. Connect the communication wires to the screw terminal strip (D) as described in
the terminal connection diagram of the communication device. Note down the
connector color coding for the respective pin numbers. Connecting the receiver
incorrectly can cause the devices to be damaged.
- Pin 2 color:
- Pin 3 color:
- Pin 5 color:
- Pin 7 color:
9. Connect the jumpers (E) if the terminal connection diagram of the communication
device indicates this as necessary. The table shown to the right provides an
overview of the jumper functions.
10. Plug the communications interface into the board (F).
11. Close the Sunny Boy as described in chapter 7.2.
Attention!
When opening the Sunny Boy, follow all the safety instructions as
described in section 3.
Electrostatic discharges are an acute danger to the Sunny Boy and to the
communications interface. Ground yourself by touching PE before removing the
communications interface from the packaging, and before touching any
components within the Sunny Boy.
Read the communication device manual before beginning installation work.
