8.2. 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 co-
rrectly, 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 inside the rack.
- Do not place objects close to the rack that may
block the entry and exit openings for 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.
