Further information on wall mounting close to the
motor can be found in the original operating and
assembly instructions of the respective frequen-
cy converter manufacturer. The electrical con-
necting cables between the motor and frequency
converter in the above cases must be suitable
shielded cables, laid using the shortest route and
without clamping and plug-in connections and
connected correctly at both sides.
• The shielding braid in the connecting cables
must be connected fully, continuously and on
both sides, i.e. to the frequency converter and
motor, and at low resistance and permanently to
protective earthing systems or the main earthing
bus bar. Suitable EMC cable glands must be used
for this on the motor side and also on the INVEOR
wall mounting plate, if necessary.
• It is important to ensure that the solid con-
nection of the device to the protective earthing
system or several suitable earthing lines is at low
resistance and permanent for blowers installed
with electrical insulation (e.g. through vibration
dampers, compensators, insulated pipes, etc.) for

frequency converter operation.

For further information about EMC compliant installation and
assembly, refer to the Operating and Assembly Instructions
issued by the frequency converter manufacturer.

peller should correspond to the direction arrow on the hous-
ing. If the impeller rotates in the wrong direction, then inter-
change L1 and L3.
3.3 Declaration concerning the EMC Directive (2004/108/EC)
Our blowers are components that are designed to be in-
stalled in other machines or systems by qualifi ed personnel,
i.e. not intended for consumers. The manufacturer of the
fi nal system/machine must guarantee/confi rm that the fi nal
system/machine complies with the EMC Directive.
Blowers with frequency converter operation (FU):
Prior to the start-up and during operation of the device on a
frequency converter it is essential that the EMC instructions
from the frequency converter manufacturer and the informa-
tion in the Elektror operating and assembly instructions are
observed in order to meet the requirements of the EC "Elec-
tromagnetic Compatibility" Directive 2004/108/EC.
If the device is delivered together with an Elektror switch cab-
inet frequency converter package, it is possible to comply
with the EN61800-3 category C2 (Industrial environments),
taking into consideration the above-mentioned EMC instruc-
tions.
Blowers with an in-built frequency converter (FUK):
Devices with an in-built frequency converter meet the require-
ments of the EC "Electromagnetic Compatibility" Directive
2004/108/EC under consideration of EN 61800-3 Category
C2 (industrial environment), taking into account the EMC in-
structions from the frequency converter and the information
in the Elektror operating and assembly instructions.
A CE conformity assessment with the relevant standards and
guidelines must be carried out in all cases before the start-
up.

4.1 Basic information

Please observe the notes on designated use in section 1.1,
as well as the safety guidelines in sections 1.2 to 1.14.
U1 V1 W1
If electrical current drops below the rated current of the drive
motor during operation, check to see if the mains voltage and
L1 L2 L3
frequency match the appliance ratings.
(L3) (L1)
After protective shutdowns, e.g. activation of the PTC evalu-
Y circuit
ation unit by motors with a PTC resistor sensor, or after a
(high voltage)
protective shutdown of the frequency converter during FU
applications, the appliance must not be restarted until the
Tightening torque
problem has been troubleshooted.
2.0 Nm
If the blower cannot be operated over the whole range of the
characteristic curve, the motor may overload if the system
3.2 Nm
resistance is too low (excessive current consumption). The
5.0 Nm
volumetric air fl ow should be reduced in this case by means
of a throttle valve fi tted on the intake or discharge side.
10.0 Nm
The blower must not be subjected to vibration or impact
loads.
4.2 Frequency converter operation
A frequency converter is used, allowing a wide range of
speed adjustments. There is only a small, load-related dif-
ference in rpm between idle state and the max. load of the
blowers and the lateral channel blower.
To ensure trouble-free operation of blowers and side
channel blowers, it is important that the converter meet
the following requirements:
• Converter output equal to or greater than motor power
• Converter current equal to or greater than motor current *)
• Converter output voltage equal to rated motor voltage
• The pulse frequency of the converter should be 8 kHz,
