9.2. Installation of the rack without

ventilation facilities

To install the units in racks without installation

facilities, and when the rack is located in a place

with a temperature of around 45°C, it is advisable

to place the rack completely open, in other words,

do not use the side doors. This is to facilitate the

ventilation of the units , fig. 5.

It is very important that this process operates

correctly, therefore the following must be

observed:

- Do not open the side doors, as this would cause

the ventilators to extract the air from the outside

rather than the air in the inside of the rack.

- Do not place objects close to the rack that may

block the entry and exit points of the air.

- If the rack is not complete, the subracks must be

placed from the top downwards without leaving

any gaps in between, fig. 4.
