• The devices may only be operated with
frequency converters.
• The frequency converter supply voltage must
only be a maximum of 400 V without the motor
fi lter. Appropriate measures such as a motor fi lter
to protect the motor must be installed on the
motor terminals with higher frequency converter
supply voltages, longer lines and/or if the pulse
voltages are exceeded (max. 1000 Vpk for drive
motors up to 0.75 kW, maximum 1300 Vpk for
drive motors larger than 0.75 kW) Please contact
the converter supplier in this case. If a motor fi lter
is included in the delivery, this must be installed
between the converter and the motor. Please
ensure that there is suffi cient space in the switch
cabinet and take into account the installation and
assembly requirements in the operating instruc-
tions of the frequency converter/motor fi lter
manufacturer.
• The maximum cable length between the mo-
tor and switch cabinet frequency converter (e.g.
Lenze Vector, Omron MX2 and Omron RX) must
not exceed 20 m. Maximum cable lengths of up to
3 m are permitted with Kostal INVEOR frequency
converters installed close to the motor and up to
10 m with Lenze MOTEC frequency converters.
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.
3.3 Confi guration for three-phase current blowers
Warning!
Danger due to loose or improperly tightened con-
nections!
Improperly tightened and loose connections
cause electric shocks, fi res, property damage and
personal injuries!
Check for loose connections and tighten in
accordance with the tightening torques in the fol-
lowing table.

Checking the direction of rotation
Switch on the blower. The running direction of the impeller
should correspond to the direction arrow on the housing. If
the impeller rotates in the wrong direction, then interchange
L1 and L3.
3.4 Declaration concerning the EMC Directive
(2014/30/EU)
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 sys-
tem/machine complies with the EMC Directive.
Prior to the start-up and during operation of the device on a
frequency converter (provided that this is suitable) it is es-
sential that the EMC instructions from the frequency convert-
er manufacturer and the information in the Elektror operating
and assembly instructions are observed in order to meet the
requirements of the EC "Electromagnetic Compatibility" Di-
rective 2014/30/EU.
If the device is delivered together with a frequency converter
package for switch cabinet or wall mounting closer to the mo-
tor, it is possible to comply with EN 61800-3 category C2 (In-
dustrial environments), taking into consideration the above-
mentioned EMC instructions.
Warning!
This product may cause high-frequency inter-
ference in a residential environment that may
require screening measures.
Blowers with an in-built frequency converter (FUK):
Devices with an in-built frequency converter meet the re-
quirements of the EC "Electromagnetic Compatibility" Direc-
tive 2014/30/EU under consideration of EN 61800-3 Catego-
ry C2 (industrial environment), taking into account the EMC
instructions from the frequency converter and the information
in the Elektror operating and assembly instructions.
Warning!
This product may cause high-frequency inter-
ference in a residential environment that may
require screening measures.
A CE conformity assessment with the relevant standards and
guidelines must be carried out in all cases before the start-
up.
