The electricity facilities in buildings supply energy to electric devices with
230 V / 50 Hz (or e.g. 120 V / 60 Hz in the USA). This electricity distribution system is
not optimized for the transmission of high frequency signals (approx. 132 kHz).
Therefore the interference-free communication in this frequency range essentially
depends on the selection of the transmission line between the units and the Sunny
Boy Control Light.
The transmission link should:
•
use only one phase and
•
be as short as possible
Pay attention about connecting all devices that transmit and receive data to one
phase or preferably even to the same line. Therefore you should choose a socket for
the Sunny Boy Control Light installed on the same line resp. at least on the same
phase as the device and is as near as possible to its feeding point.
In case the Sunny Boy Control Light and the according devices must be connected
to different phases the installation of a phase coupler can be necessary. Phase
couplers are available from SMA and must be installed on the site by a qualified
technician.
Further information on optimizing the installation is available in chapter 7.2.1
"Transmission Errors".
If there are any other users of Powerline equipment in your neighborhood, you
should have an eye on the device detection and pay special attention to the
according dialogs in order to ensure that you detect your own devices only. Sunny
Boy Control Light can run the device detection automatically if there is no special
interference. All device detection dialogs will be confirmed automatically after 60 sec
and therefore all devices found will be registered. All you have to do after the
automatic device detection is done by Sunny Boy Control Light is to exit the device
detection by pressing the
[[[[
ESC
]]]]
key and confirm the final security dialog with
[[[[
Enter
]]]]
