Application

EN

The fans may only be operated when
they are installed as intended, and
when safety is ensured by safety

protection measures.

• For motors without a temperature monitor, a

1 Application

• Cross flow fans (type designation see rating
plate) are not ready-to-use products, but
designed as components for aerodynamic
devices, machines and installations.

equipment according to DIN EN ISO
13857 (DIN EN ISO 1210 0) or b y oth er

motor cut-out switch is to b e used for P1 > 750
W (P2 ≥ 500 W)!

• Blocking or braking the fan by, say, pushing
objects into it is forbidde n. This leads to heat ed
surfaces and damage to the impeller.

• It is not possible to exclude a residual risk due
to incorrect use, malf unction or force majeure.
The designer or constructor of the installation
must take suitable safety measures in
accordance with DIN EN 12100, e.g. protec
tion devices, in order to prevent hazardous
situations arising.

• Cross flow fans are suited to a wide range of
applications due to their slim construction
design. They stand out against other fans
particularly by virtue of their broad laminar air
band with favourable noise res ponse.

• Speed control through voltage reduction is
possible, depending upon the application.

• All fans are dynamically balanced on two
planes in accordance with DIN ISO 1940,
Section 1.

2 Safety instructions

• The cross flow fans are only intended for the
transfer of air or air -like mixtures. They ca nnot
be used in hazardous ar eas for the transfer of
gas, mist vapours or mixtures . Nor can the y be
used for the transfer of s olid components i n the
transfer medium.

• Mounting, electrical connection and
commissioning may only be carried out by
trained specialized p ersonnel who observe the
relevant regulations!

• The fan is only to be operated within the ranges
specified on the type plate!

• Use the fan only in the authoris ed fashion and
only for the tasks and flow media specified in
the order!

• Designer, manufacturers or operators are
responsible for proper and safe installation as
well as for safe operation!

• Safety features, e.g. guard gr illes, are no t to be
dismantled, circumvented or made inoperative!

• If thermal protector is integrated into winding as
motor protection, the thermal protectors must
be connected.

• If the temperature monitor is not integrated into
the motor circuit (→ wiring diagram), a tripping
device is required.

3 Note on the ErP directive

Rittal GmbH & Co. KG wishes to point out that,
based on the directive (EU) no. 327/2011 of the
Commission of 30th of March 2011 for enforcing
directive 2009/125/EC (hereinafter referred to as
ErP directive), the operat ional area of certain fans
within the EU is bound by certain prerequisites. The
fan may only be used within the EU when it m eets
the requirements of the ErP directive.
If the said fan does not have a CE mark (cf.
especially the rating plate), use of this product
within the EU is not admissible.
All ErP-relevant information comprises
measurements which are determined using a
standardised measurement set-up. More details
can be obtained from the manufacturer.

4 Transport, storage

Wear safety shoes and gloves for handling!

• Transport the fan(s) either in the original
packaging or using the transport fixtures
provided (mounting br ackets and bored holes).
Use suitable lifting equipment, insofar as
required by the dimensions or weight.

• Do not transport the fan by the connecting
cable!

• Avoid excessive vibration and shocks.

• Be on the alert for any damage to the

packaging or the fan.

• Store the fan in the origina l packaging in a dry
area protected from the weather or protect it
from dirt and weather until final installation.

• Avoid exposure to extreme heat and cold.

• Avoid excessive storage periods (we

recommend a one year max.) and inspect the
motor bearings for proper operation prior to
installation.
