WARNING!
Incorrect parameterization
of the inverter
If inadmissible parameters
are set at frequency or
speed, this leads to motor
overload and/or destruction
of the fan. There is a risk of
personal injury.
Use only the infor-
mation on the perfor-
mance plate
Connect the tempera-
ture sensors at the in-
verter inputs
Please keep the infor-
mation in the manufac-
turer's documentation
from the frequency in-
verter
Important information about
acceleration and deceleration
In order to avoid high component
loads and malfunctions in inverter
operation, the following times ap-
ply for the respective device en-
gine power class (see name-

Table 8: Acceleration and Deceleration
Times
Within the acceleration and deceleration
times, a steady rise and fall must be
guaranteed.
During operation, no speed changes
may occur that exceed the speed
change during the acceleration and de-
celeration.
