Description Function and application The EASY PB Coupler is connected to an EASY control unit via the supplied Y-connector and thus enables the connection of standard pushbuttons, switches, motion detectors or timer switches with a potential-free closer contact to an EASY light control system. EASY PB Coupler The EASY PB coupler is installed in a flush device box behind the respective switch insert, pushbutton insert or distributor box. Function The EASY PB Coupler converts the button or switch operations to corresponding digital telegrams and transmits them to the control units of type DALI EASY II or OT EASY 60. The functions of the connected pushbuttons or switch contacts are assigned by means of the DIP switch setting. A GND T8 T7 T6 T5 1 2 3 4 C The EASY PB Coupler is operated with safety extra low voltage and is directly supplied over the EASY signal line. An additional supply is not necessary. S1 S2 S3 S4 T1 T2 T3 T4 B Design The pushbutton coupler is made up of the following components: GND • Connection terminals T1 to T8 for up to eight pushbuttons, switches or potential-free contacts (A) D Pushbutton coupler Fitting instructions • DIP switches (B) A • Connection terminals for signal lines (C) • Housing (D) Installation Safety instructions The pushbutton coupler must only be installed and put into operation by a qualified electrician. The applicable safety regulations and accident prevention regulations must be observed. WARNING! Exposed, live cables. Danger of electric shock! • Only work on the pushbutton coupler when it is de-energised. CAUTION! Destruction of the pushbutton coupler and other devices due to incorrect installation! • Do not wire the control and pushbutton lines with an external voltage, especially not a mains voltage of 230 V. L N • Do not install the pushbutton coupler in the same housing with other parts that conduct mains voltage. T5 T6 • The pushbutton coupler is designed for installation in flush device boxes. If mounted separately, for example in a separate distributor box, provide for sufficient cable strain relief and adequate insulation against parts that conduct mains voltage.
