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.
The fans may only be operated when
they are installed as intended, and
when safety is ensured by safety
equipment according to DIN EN ISO
13857 (DIN EN ISO 12100) or by other
protection measures.
•
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 response.
•
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 cannot
be used in hazardous areas for the transfer of
gas, mist vapours or mixtures. Nor can they be
used for the transfer of solid components in the
transfer medium.
•
Mounting, electrical connection and
commissioning may only be carried out by
trained specialized personnel 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 authorised 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 grilles, are not 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.
•
For motors without a temperature monitor, a
motor cut-out switch is to be used for P1 > 750
W (P2
≥ 500 W)!
•
Blocking or braking the fan by, say, pushing
objects into it is forbidden. This leads to heated
surfaces and damage to the impeller.
•
It is not possible to exclude a residual risk due
to incorrect use, malfunction 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.
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 operational area of certain fans
within the EU is bound by certain prerequisites. The
fan may only be used within the EU when it meets
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 brackets 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 original 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.
