AS-i Bus Cables
AS-i bus cables carry the signals and supply the sensors and actuators connected to the bus with 30 Vdc.
Types of AS-i cables:

Polarized AS-i ribbon cable
Color: yellow. Wire cross-section: 1.5 mm2
Standard round cable
Wire cross-section: 1.5 mm2 or 2.5 mm2
Recommended cable: Product reference H05VV-F2x1.5, conforms to the DIN VDE 0281 standard. Wire cross-section: 1.5 mm2.
Cable Routing
The AS-i cable and the power cables carrying higher power levels must be in separate ducts, which are protected by a metal screen.
When using a shared route for control cables it is essential that the connections on these control links should conform to the technology rules (e.g. the discharge diode or limiters on the terminals of self-inductive elements etc.).
Connector
A set (connector + cover) is delivered with the module, which is used to connect the module to the AS-i bus. This connector must be linked to the cable of the AS‐i bus and assembled by the user according to the procedure described later.

Action
1
Connect the 2 wires of the AS-i cable to the connector, taking the polarities into account:
