Technical Customer Information Ambience Conditions and Mechanics ACC Distance Control Radar 2nd Generation 0 265 K60 059 3 Mounting conditions 3.1 Installation instructions for the ACC2 - SCU The ACC SCU is installed in the frontal area of the vehicle. The sensor lens points in the vehicle driving direction, the connector either down to the road or up. The outline dimensions of the sensor are shown in the following drawing: Issue Date 30.01.03 Dep.: AE-DA/ELR Name: Hildebrandt Print-Date: 13.01.
Technical Customer Information Ambience Conditions and Mechanics ACC Distance Control Radar 2nd Generation 0 265 K60 059 Ideally the sensor is to be integrated into the front-end without a cover in front of its lens. If the sensor is to be installed behind a cover or a radome, special care must be taken in selecting the cover-material, cover shape (or design) and position of the cover relatively to the sensor.
