Installation
4.1
Choosing the installation site
When choosing the installation site for the enclosure,
please observe the following:
– The site for the enclosure, and hence the position of
the roof-mounted fan, must be carefully selected so as
to ensure good ventilation.
– The site must be free from excessive dirt and moisture.
– Roof-mounted fans must always be installed on hori-
zontal panels (roof).
– The ambient temperature must be lower than the ad-
missible enclosure interior temperature.
– The mains connection data as stated on the rating
plate of the unit must be guaranteed.

Notes on installation
4.2.1
General
Check the packaging carefully for signs of damage.
Any packaging damage may be the cause of a subse-
quent functional failure.
– The enclosure must be sealed on all sides (IP 54). If the
enclosure has a leak, unfiltered, contaminated air may
enter the enclosure.
– The fan motor is a rotating component that may trans-
fer vibrations and oscillations.
– Appropriate measures to decouple vibration must be
taken in advance by the company responsible for the
overall plant or system.
– During transportation, the roof-mounted fan must be
secured in accordance with section 4.3 "Installing the
roof-mounted fan" (installation for protection category
IP 55) to prevent damage.
4.2.2
Layout of the electronic components in the
enclosure
Take note of the air flows from the internal fans of in-
stalled electronic components.
When installing the roof-mounted fan, it is important to
ensure that the airflows of fans and built-in electronic
components do not adversely influence one another
(air short-circuit).
The corresponding minimum distances between the
fan and component must be observed in order to en-
sure unhindered air circulation.
