    7 Installation 7.1 Mechanical installation 7.1.1 Preparing a site Special local, state or national regulations apply for working in and on roadways. Observe these regulations and prepare the intended installation area for the sensor accordingly . The device must be installed in the center of the road lane. On two-lane roads the device is installed in the left-hand lane.

  • Page 14: Installing Device

    4 For the device: mark and drill a hole with a diameter of 16 cm and depth of 6 cm into the road surface. 4 For the connection cable: cut a slit with the width of 2 cm and depth of 5 cm into the road surface. Optionally one or two temperature depth sensors are installed: One of the external temperature depth sensors is marked with a red cable flag, on which the intended installation depth is given.

    4 Ensure that the cable connections are neither opened nor damaged. 4 Do not install the device with a damaged cable. 4 Have repairs carried out by OTT HydroMet service personnel. 4 Place the supply cable in a protective tube.

  • Page 16: Extending Supply Cable

    4 Avoid tensile stress on the cables. 7.2.2 Extending supply cable Shortening the supply cable is only permitted at the cabinet end of the cable. The loop impedance of the entire cable must not exceed 10 Ohm. 4 Shorten the original cable after the shortest possible distance (curbside 5 m). 4 Extend the cable by attaching an extension cable to the original cable.

  • Page 17: Connecting Power Supply

    RS485 termination resistance required means that a resistance of 120 Ohm should be connected parallel to the RS485 2-wire interface, either on the sensor inlet or sleeve. Recommended extension cable: A-2YF(L)2Y Nx2x0.8 or similar. Core pair 2x (2 times) means 2 pairs of wires, e.g. 2x2x0.8, because 2 individual wires are 1 pair for the power supply (+ and -). 7.2.3 Connecting power supply The road sensor supply cable is connected to the power supply in the control panel.
