4.1.1 Installation
The bus cable system is flexible in terms
of configuration – it can be star-connected
or series-connected to the fans.
The cables connecting to the fan must be
flexible (e.g. LiYY). In order to avoid cable
breakage, do not use any cables with solid
wire.
The segment length L
ries-connected and star-connected fans
varies according to the selected cable
cross-section:
