ventilation, you must mount blank plates ref.

correct ventilation of the equipment, fig. 4.
of the Rack. The air will enter again through
the lower part of the device, fig 3.
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 8PSK-QAM is located in
warm place, with a temperature higher than
40°C.
These ventilators will be placed on a tray,
that is screwed onto the top part of the
Rack, fig. 1 and 2, and in this way the
ventilators will be able to extract the air from
the 8PSK-QAM and will be able to expel it
via the gap (approx. 3-5 cm) at the top part
