RECOMMENDED CABLE TYPES FOR NETWORKS
Please note that these recommendations are for the Rapid lighting control system only. It is always the electrical installer's responsibility to ensure that the control system is installed in a safe manner using suitable equipment in line with the latest edition of the electrical regulations.
These cable types have been tested and approved for use with Rapid systems. Should any other nonapproved cable type be used then CP Electronics will not accept responsibility for non-functioning systems.
If the chosen cable is to be installed within the same compartment as mains cable, then ensure they are appropriately rated to the latest regulations. Otherwise, they may need to be installed in a separate containment rated appropriately for extra low voltage cables

Basic Backbone Connection Details
The basic backbone network connects area controllers together using 3 pairs of an unscreened twisted pair (UTP) data cable Preferred cable options listed below
See subsequent section when integrating this further with the front end supervisor.

DALI network cable connection details (between DALI devices)
DALI bus is intended to be installed within mains rated containments and MUST therefore be given the same insulation safety considerations against electric shocks as that of mains cable.
If the cable has a screen and drain wire, the drain wire must be connected throughout in order to make the screen continuous. This can be done with the use of a connector block. The screen drain wire must be grounded to earth at the gateway ONLY and all other points must be isolated from earth.
