Assembly and installation instructions
18. Cabling
Route all low voltage cables along the shortest route.
Ensure that low-voltage and power cables are separated, using metal
partitions on cable harnesses.
Use only shielded cables as low-voltage and bus cables.
Lay all BUS cables in a linear pattern. Star-shaped wiring is not permitted
(Figure on left).
The KaController is connected via a bus connection to the respective
KaControl PCB on the unit.
Lay shielded, paired cables, e.g. UNITRONIC® BUS LD 2X2X0.22 or similar,
separately from power cables!
When laying bus cables, avoid the formation of star points, for instance in
junction boxes. Loop the cables through to the unit!
