6 Electrical Connection
All connection cables are fed through the feed-throughs on the underside of the device
(see following figure) and connected to the appropriate connections inside the Sunny
Island 5048.
Use the provided cable screw connections to fasten the cables inside the Sunny Island
5048 housing in a manner conforming to the appropriate standards. The metric-thread
cable screw connections guarantee a dust-free and waterproof installation of the cables
in the housing and also provide strain relief for the cable connection. Close all unused
openings in the housing using the appropriate dummy plugs (the dummy plugs are
already installed on AC2 and DC-Ground upon delivery).
Obtain an overview of the different components and connection areas of the Sunny
Island 5048 (see section 2.2 "At a Glance" (Page 15)).
The electrical installation of the Sunny Island 5048 must be made by suitably
qualified personnel only (qualified electrician). Before beginning to install your
Sunny Island 5048, identify any potential hazards and take any necessary
precautions (see section 3 "Safety Instructions" (Page 23)).
If the device is connected incorrectly, a significant danger of injury or
death arises and damage to the device, system or plant may also result.
