8. Norms for rack mounting (max. 49 TWIN MODULATOR - 7 subracks with 5 units in height - 8,7")

8.1. Installation of the rack with

ventilation facilities

To facilitate the renewal and circulation of the air

inside the rack, to reduce the temperature of the

units and thus improving their characteristics, it is

advisable to place 2 ventilation units of 25W, par-

ticularly when the rack with the Twin Modulator is

located in warm places, with temperatures higher

than 45°C.

These ventilators will be installed on a tray that is

fi xed inside the cabinet (fi g. 1 & 2). This way, the

ventilators will force the fresh air entering from the

base of the cabinet, to circulate between the mod-

ules and be expelled through a gap on top of the

cabinet (3-5 cm approx.). See fi g. 3.
