Anleitung Zusammenfassung


Mechanical drawings of the other models can be found in chapter 3.5 or in the respected datasheet. Fig 7 - The LBC 3253/00 dimensions are shown, including the vertical spacing between the upper and the lower bracket as well as the vertical offset of the acoustical reference. 2.5.3 Mounting procedure. A short general mounting procedure is described, the actual procedure may differ slightly depending on the actual circumstances and the chosen mounting method. It is assumed that the cabling is already prepared and all connectors are fitted as described in chapter 2.3 and 2.4. The recommended procedure is as follows: 1. Use plugs in combination with hexagon head screws, this allows the use of a flat key that fits behind the bracket to fasten the screws. Select a type with a maximum head size not exceeding 11.5 mm (0.45”). 2. Drill the holes for attachment of the brackets into the wall. It is advised to make use of the slotted holes (two for each bracket, refer to Fig 6) for standard vertical mounting of the column. 3. Insert the plugs and screws into the holes. It should be possible to slide the bracket over the heads. Check this with a bracket before mounting it to the column). 4. Check if the chosen mounting holes ensure that the final position of the column will be in the vertical angle that is specified (which is usually exactly perpendicular to the listening area). Use extra spacers if necessary. 5. Remove the front grill(s) of the Intellivox before mounting the unit and remove the protection foam. This can be accomplished by gently lifting the grill at the positions of the ‘snap-in’ fittings which hold the grill. 6. Remove the cover of the connector compartment. Make sure the panel is not interchanged with the panel of another unit, because this will also exchange the external serial numbers. 7. Lift the column and slide the brackets over the heads of the screws. Make sure all cabling is fitted through the connector compartment and accessible from the front side. 8. Firmly fasten the screws which secure the brackets to the wall. 9. Re-check if the column is in an exact perpendicular position or in the vertical angle that is specified. 10. Insert the connectors and reassemble the connector compartment cover and the grill(s). Bosch Security Systems | July 2003 Intellivox DDC | Installation Manual | Appendix EN | 13 3.

The ground (GND) terminals on the electronics module serve different purposes. 1. Safety. The GND terminal located at the mains IEC connector provides a direct low impedance path from the metal parts of the chassis to ground. In conjunction with a proper designed mains distribution network, this offers extra safety in situations where the standard class 2 insulation is not sufficient (fire, moisture etc.). Always connect the IEC ground terminal. 2. Reduction of RF emission. Although the Intellivox electronics module is well shielded and external connections are de-coupled to prevent RF emission from the internal high speed digital circuits, this protection will not work properly when the chassis has no solid ground reference. 3. Immunity. The GND terminal shorts currents which are induced by (RF) fields in the signal cables effectively to chassis-ground, provided that the cable shield is of sufficiently low impedance. To make things even more complex, the RS-485 terminal of the chassis also has a DGND pin, while the ambient SPL/temperature terminal has both GND and AGND pins. The pins labeled GND are connected directly to the chassis. The RS-485 DGND pin is not a ground pin, but serves as a reference for the RS-485 AB and YZ wires. Although the DGND pin should be connected to the shielding of the RS-485 cable (when in use), DGND (and ABYZ) has no relation to GND except for the fact that the voltage between DGND and GND is clamped to a maximum voltage of 50 V for reasons of safety and immunity. In an installation with a connected network, the RS-485 cable shield must be grounded at some central position. • DGND should not be connected to any other ground pin (GND or AGND) on the chassis.
