USER MANUAL 2948 BERKER

Caution! The installation and assembly of electrical equipment may only be performed by a skilled electrician. Not suitable for disconnecting. This timer has been designed for the automatic switching of lights. If they are used for any other purposes which may entail hazards (e. g. switching heaters) such hazards will have to be eliminated by the user by taking additional suitable safety measures.

This Timer-insert is a system component to be installed into a 60 mm flush box (recommendation: deep box) in conjunction with the timer attachment with time switch function. The device facilitates the programmed, time-controlled switching of various lighting fittings (please refer to Specifications). Due to the use of an efficient relay with potential-free contacts, consumers of up to a maximum of 1000 W can be switched. Via two separate extension inputs, the consumer can be switched by a mechanical push-button (two-key principle, 2x n. o. contacts). The Timer-insert has six connecting terminals and one plug connector for contact with the attachment. In addition, a three-pole terminal (added to the attachment) can be positioned in the insert. This terminal serves for connecting a twilight sensor.13

3. Installation Instructions

Important: The sensor line carries protective low voltage (SELV). Please observe the installation procedures as specified by VDE 0100. Connecting the Sensor: Buried Wiring (Figure A): Choose suitable cable for buried installation of the sensor line. Recommendation: J-Y(ST)Y 2x2x0.6 mm telephone cable. The individual wires of the sensor line should be put through flexible insulating tubing (added to the attachments with sensor evaluation). Then, together with the flexible insulating tubing, push the line through entrance c of the insert and through duct d to terminal e. The insulating tubing must cover the individual wires from the cable sheath to the connecting terminal. Put the connecting terminal (added to the attachments with sensor evaluation) in the insert as shown in the illustration. Surface Wiring (Figure B): Lead sensor line c behind the supporting plate (between the wall and the supporting plate) through opening d into duct e of the insert. The line must be led directly through the duct to connecting terminal f. The line must be precisely in the duct and must not form any loops towards the 230 V connecting terminal space. Connect the sensor line as shown in the opposite illustration. Wire marking: Sensor: ‘Earth’ = marked. Adapter, extension line: ‘Twilight’ = marked. ‘Earth’ = middle wire. The Timer-insert can only be used in conjunction with the Timer attachment with time switch function. Timer-insert c is provided for installation in a 60 mm flush box (recommendation: deep box). The connecting terminals of the insert must be down. Plug attachment d onto the insert together with frame e. Electrical contacting is established through plug f and g. (For the description, installation and connection of the attachment, please refer to separate instructions.)
