4 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.
4.2 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.
