15.1 Connection of the Interface
1. Open the Sunny Island 3324/4248 as described in section 6.1 "Removing the
Cover" (Page 55).
2. Insert the communications cable through the metric-thread cable screw
connection.
3. Thread the cable through the cable feed-throughs (A) on the Sunny Island
3324/4248.
4. Now firmly tighten the metric-thread cable screw connection clamp on the Sunny
Island 3324/4248.
5. Sheathe the cable inside the Sunny Island 3324/4248 using the silicon tube
provided. The silicon tube is imperative for safety reasons. Without this silicon
tube, the interface is not to be operated.
6. Lay the cables in the area (B), as shown in the following figure.
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.

When opening the Sunny Island 3324/4248, follow all the safety
instructions as described in section 3.2 "Potential Hazards"
(Page 20).
Electrostatic discharges are an acute danger to the Sunny Island 3324/4248
and to the communication interface. Ground yourself by touching PE before
removing the communication interface from the packaging, and before
touching any components within the Sunny Island 3324/4248.
Read the communication device manual before beginning installation work.
