FLEXIDOME 5000 AN Connection and set-up | en 19Bosch Security Systems Installation Manual AM18-Q0648 | v1.0 | 2013.034 Connection and set-up4.1 Power and video connectionsThe wiring harness has a BNC connector to accept the videocoax cable (with male BNC connector) and two stripped lowvoltage power wires for connection to a power connector. AUTP adapter (VDA-455UTP) is available as an optional accessoryto allow a UTP video cable to be connected to the BNCconnector.The easiest way to connect the cables is as follows:1. Bring the building connections through the surface cablehole so that they hang clear.2. Partially insert two screws into the pre-drilled holes (oradapter plate).3. Using one of the keyholes, hang the mounting base of thecamera module on one screw temporarily; tilt the baseslightly to gain access to the cable connections.4. Connect the BNC connector of the camera module to thevideo coax cable.5. Connect the stripped power wires (red +, brown –) to thepower supply connector.NoteFor a DC supply the polarity is important. Incorrect polaritydoes not damage the camera but it will not switch on.6. In damp environments ensure that the connections aresealed. (The surface mounting box and the other mountingaccessories have a sealed compartment for this purpose.)7. Push the connections back through the surface cable hole.8. Secure the mounting base of the camera module to thesurface with three screws.
