It is very important that this process operates cor-
rectly, 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, fi g. 4.
8.2. Installation of the rack without
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 , fi g. 5.
