10.4.3 connection with multi-pole cable and ribbon cable terminal
As an alternative to the bus connection model with 4-pole circular plug, there is the control head with multi-pole
cable (M12 circular plug) and ribbon cable terminal. The wiring diagram of the circular plug corresponds to the bus
connection of the M12 4-pole circular plug (see "Figure 25" and "Figure 26") and can easily be connected to the
ribbon cable terminal (see “Figure 30”).

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.
