3.2 Function
The roof-mounted fan in conjunction with the corre-
sponding inlet filter(s) is used to dissipate heat loss from
enclosures and ventilate the enclosure, thereby protect-
ing temperature-sensitive components. This is achieved
via the direct infeed of ambient air, the temperature of
which must be lower than the admissible enclosure inte-
rior temperature.
3.2.1 Control
Rittal roof-mounted fans may be controlled more effi-
ciently with the following accessories:
* Not compatible with 3140.140.
3.2.2 Safety devices
The fan is equipped with a thermal winding protection for
protection against overload.
3.2.3 Filter mats
The roof-mounted fan is supplied with four class G3 filter
mats installed. The filter must be checked regularly de-
pending on the level of dust exposure, and replaced as
necessary.
3.3 Proper use
Rittal roof-mounted fans were developed and designed
in accordance with the state of the art and the recog-
nised rules governing technical safety. Nevertheless, if
used improperly, they may pose a threat to life and limb
or cause damage to property. The unit is only intended
for ventilating enclosures and electronic cases. Any oth-
er use is deemed improper. The manufacturer will not be
liable for any damages caused as a result of improper
use, or for incorrect assembly, installation or use. All risk
is borne solely by the user.
Proper usage also includes the observation of all valid
documents and compliance with the inspection and ser-
vicing conditions.

3.4 Scope of supply
The roof-mounted fan is supplied in a packaging unit in
a fully assembled state and ready to connect.
 Please check the scope of supply for completeness.
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.

5.1 Electrical connection
5.1.1 Notes on electrical installation
When performing the electrical installation, it is important
to observe all valid national and regional regulations as
well as the provisions of the responsible electrical supply
company.
The electrical installation must only be carried out by a
qualified electrician who is responsible for compliance
with the existing standards and regulations.
5.1.2 Connection data
– The connected voltage and frequency must corre-
spond to the values stated on the rating plate.
– The electrical installation and any repairs may only be
carried out by authorised specialist personnel.
 Use only original spare parts!
 Install the pre-fuse cited in the Technical Specifica-
tions (circuit-breaker or slow fuse) to protect from
short-circuits.
– If several fans are operated on a single pre-fuse, ob-
serve the total connected load.
– The roof-mounted fan must be connected to the
mains via an all-pole disconnecting device to overvolt-
age category III (IEC 61058-1).
5.1.3 Overvoltage protection and supply line load
– The unit does not have its own overvoltage protection.
Measures must be taken at the supply end by the
switchgear manufacturer or operator to ensure effec-
tive protection against lightning and overvoltage. The
limits specified in standard UL/IEC/EN 60335-2-40
must be observed.
– The units are classified as overvoltage category III. The
mains voltage must not exceed a tolerance of ±10%.
5.1.4 PE conductor connection
The PE conductor must be connected to the PE con-
ductor system of the overall system.
5.1.5 Installing the power supply
 Remove the mains connector from the packaging and
connect to the mains as shown in the connection dia-
gram.
Note:
The position of the roof-mounted fan in the
mounting cut-out is freely selectable. It
should be based on the position of the elec-
trical connection inside the enclosure.
Note:
No filter mats are needed in order to achieve
protection category IP 20.
Note:
Check that the clips are completely snapped
into place to ensure that the roof-mounted
fan is securely held in the mounting cut-out.
Note:
The filter mats may be removed to achieve a
higher air throughput. In this case, the pro-
tection category will be reduced to IP 22 and
UL Type 1.
Note:
Use only original Rittal filters which bear the
Rittal logo to be sure of the protection cate-
gory, air throughout and approvals.
Note:
You should inspect the filter regularly de-
pending on the amount of dust. Recom-
mended: Replace after 2,000 operating
hours at the latest, and as and when neces-
sary.
Note:
The side with the Rittal logo must be pointing
towards the fan.
Note:
The orientation of the cover on the base tray
is freely selectable.

 Select the conductor cross-section according to the
pre-fuse (0.5–4 mm² single-wire, 0.5–2.5 mm² fine-
wire).
A smaller pilot wire may be selected (min. 0.34 mm²).

5.2 Installing the pilot wire
To control the EC roof-mounted fans via an external
control unit (e.g. 3235.440), types 3140.5xx have addi-
tional connections for the pilot wire.
 Release and remove the jumper between the "+10 V"
and "0 – 10 V/PWM" (terminals 1 and 2) connections.
 Use a screwdriver with a 3.5 x 0.5 mm blade.
 Open the terminal with the screwdriver and insert the
connection cable as shown in the connection dia-
gram.
 Remove the screwdriver.

Note:
In accordance with NFPA 70 (NEC), only
copper conductors must be used to connect
the supply cable to the mains connector.
Note:
To operate without a pilot wire, the jumper
should be left in the connection terminal. The
unit will then be operated at maximum

6 Commissioning
 Once all the assembly and installation work is com-
plete, switch on the power supply to the roof-mounted
fan.
The roof-mounted fan operates automatically, in other
words, the fan will start up once the power has been
switched on.
7 Inspection and maintenance
The installed maintenance-free fan is mounted on ball
bearings, protected against moisture and dust, and fit-
ted with a temperature monitor.
The life expectancy is at least 50,000 operating hours
(L10, 40°C).
The roof-mounted fan is therefore largely maintenance-
free.
From time to time, the components may need to be
cleaned using a vacuum cleaner or compressed air if
they become visibly dirty.
Any stubborn, oily stains may be removed using a non-
flammable detergent, such as degreaser.
Sequence of maintenance work
– Check the level of dirt: If necessary, vacuum the fan
housing, or clean with compressed air.
– Filter soiling: Replace the filter.
– Check the noise generation of the fan.
8 Storage and disposal
Facilities for disposal are available at the Rittal plant.
Please contact us for advice.
Note:
EC roof-mounted fans start running with a
delay of approx. 15 sec.
Note:
The roof-mounted fan must not be exposed
to temperatures above +70°C or below
-30°C whilst in storage.
