9.1. Installation of the rack with

ventilation facilities

To facilitate the renewal and circulation of the

air inside the rack, and the temperature of the

units and thus improve their characteristics, it

is advisable to place 2 ventilation units of 25W,

particularly when the rack with the DVBS2-

COFDM (CI) T0X is located in warm place, with a

temperature higher than 45°C.

These ventilators will be placed on a tray, that is

screwed onto the top part of the Rack, fig. 1 and

2. This way, the ventilators will force the fresh air

entering from the base of the cabinet, to circulate

between the modules and be expelled through a

gap on top of the cabinet (3-5 cm approx.). See fig.

9. Norms for rack mounting (max. 35 DVBS2-COFDM (CI) T0X - 7 subracks with 5 units in height - 8,7”)
