TECHNICAL SHEETS
Description
This cable is used for the distribution of the power supplies and the operating signals to
all BUS system devices.
The cable consists of a white external sheathing and two twisted exible conductors
with a section of 0.5 mm2, one brown and one brown/white.
The cable is sold in 200 m coils.
It is thus suitable to be used:
- in the open air, inside trunkings, passage-ways and pipes
- inside walls with suitable pipes.
- laid underground by means of suitable pipes
The white SCS-BUS cable is suitable for underground installation

Installation notes
Underground cable installation
The 336904 BUS SCS cable can be installed underground (protected using appropriate
piping), together with other signalling cables, provided the voltage is <50V.
It is however strictly forbidden to install the 336904 cable in the same conduit as power
supply cables with voltages >50V. Failure to comply with the installation requirements
will relieve BTicino of all responsibilities for the operation of the system installed.
Installation together with other cables
Although the construction of the white cable guarantees the necessary electrical
insulation level for installation together with 450/750 V system cables, it is however
not capable of guaranteeing immunity from any electromagnetic disturbances that may
occur when installed in the same conduits used for the power supply cables.
It is therefore strongly recommended that the white BUS/SCS cable and the power
supply cables are installed in separate conduits.
