FlexiDome2X Connection and set-up | en 21 4 Connection and set-up 4.1 ! Power and video connections The wiring harness has a BNC connector to accept the video coax cable (with male BNC connector) and two stripped low voltage power wires for connection to a power connector. A UTP adapter (VDA-455UTP) is available as an optional accessory to allow a UTP video cable to be connected to the BNC connector. WARNING! Before proceeding, disconnect the power from the power supply cable. Ensure that the voltage of the unit matches the voltage and type of the power supply being used. The easiest way to connect the cables is as follows: 1. Bring the building connections through the surface cable hole so that they hang clear. 2. Partially insert two screws into the pre-drilled holes (or adapter plate). 3. Using one of the keyholes, hang the mounting base of the camera module on one screw temporarily; tilt the base slightly to gain access to the cable connections. 4. Connect the BNC connector of the camera module to the video coax cable. 5. Connect the stripped power wires (red +, brown -) to the power supply connector. Note For a DC supply the polarity is important. Incorrect polarity does not damage the camera but it will not switch on. For an AC supply maintain a consistent wiring polarity in multiple camera systems to help avoid potential camera video rolling. Bosch Security Systems Installation Manual AR18-08-B010 | v1.0 | 2009.03
