speed / frequency indicated on the
nameplate must not be exceeded.
3.6.1 Continuous Operation S1
The fans are designed for continuous
operation (operating mode S1 according
to IEC 60034-1).
3.6.2 Speed-controlled operation
S9
Operation with non-periodic load and
speed changes. The rotational speed of
the fan is controlled by a control element
or manually via the frequency inverter.
3.7 Natural Frequencies
Measures for natural frequencies
Mechanical components have natural
frequencies. Excitation frequencies or a
stimulation to unacceptably high vibra-
tions can lead to component failure. This
can cause damage to housings, impel-
lers, attachments, bearings or shafts.

4.2 Delivery
4.2.1 Scope of Delivery
Immediately check the fan for complete-
ness upon receipt. The scope of delivery
can be found in the order confirmation.
4.2.2 Checking for transport
damage
Check the fan for transport damage im-
mediately after delivery at the installa-
tion site. If transport damage is present,
these must be reported to the manufac-
turer immediately. We recommend doc-
umenting the transport damage with
photos.
Damage to the fan can pose an in-
creased safety risk. Damaged fans
should therefore not be put into opera-
tion.
