Electricalinstallation
handling the ribbon cable terminal
The multi-pole cable features a ribbon cable terminal - with M12 plug-in
connector branch circuit - for AS-Interface cable harness. The ribbon
cable terminal contacts the AS-Interface cable harness by means of
penetration technology which allows installation by “clipping in” the AS-
Interface cable harness without cutting and without removing insulation.
procedure:
→
Open the ribbon cable terminal
(loosen screws and remove cover).
→
Insert cable harness to fit closely.
→
Close ribbon cable terminal again.
→
Tighten the screws
Loosen the thread-forming screws slightly (approx. 3/4 turn to the
left) and position them on the existing threaded hole and screw in.
9.3.2 as-interface connection
AS-Interface (Actuator Sensor Interface) is a field bus system
which is used primarily for networking binary sensors and actuators
(slaves) with a higher-level control (master).
Bus line
Unshielded two-wire line (AS-Interface line as AS-Interface cable
harness) along which both information (data) and energy (power
supply voltage for the actuators and sensors) are transmitted.
network topology
Freely selectable within wide limits, i.e. star, tree and line networks
are possible. Further details are described in the AS-Interface Spec-
ification (A/B slave model conforms to the version 3.0 specification
