9 Installation This chapter has been written for the service technicians to read in case of installation. WARNING Only specialized personnel shall perform installation work. Installation work performed by personnel other than specialized personnel may cause breakdown of the equipment, poor performance, fire, severe electric shock and other property and human damages. 9.1 General Proper installation of a radar unit is essential for extracting full capability of the unit reliably and for facilitating troubleshooting and maintenance. Follow the guidelines given below when installing the radar unit. (a) Install the scanner unit as high as possible while taking its weight into consideration. (b) Install the display unit in the wheel house for comfortable observation. (c) The scanner unit and display unit are connected by 10 to 20 m compound cable with 20 conductors with an internal shield. The maximum permissible cable length is 20 m.
