• Only motors must be used on the frequency
converter that are marked on the rating plate with
the option “/FU”, “suitable for use with a frequen-
cy converter” or that were ordered and con fi rmed
as “suitable for use with a frequency converter”.
• 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 su ffi 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.
Further information on EMC-compliant installation and as-
sembly work can be found in the information in the operating
and assembly instructions of the frequency converter sup-
plier.
Checking the direction of rotation
Brie fl y switch on the blower. The direction of rotation of the
impeller must correspond with the directional arrow on the
housing.
3.4 Special Connections and Additional Terminals
Connection diagrams for FC-motors are included as part of
the delivery in the motor terminal box.
3.5 Declaration Concerning the EMC Directive
(2014/30/EU)
Our blowers and side channel blowers are components that
are designed to be installed in other machines or systems
by quali fi ed personnel, i.e. not intended for consumers. The
manufacturer of the fi nal system/machine must guarantee/
con fi rm that the fi nal system/machine complies with the EMC
Directive.
Blowers and side channel blowers with mains operation:
With mains operation to a sinusoidal AC voltage, the asyn-
chronous motors with a squirrel-cage rotor that are built into
the devices meet the requirements of the EC “Electromag-
netic Compatibility” Directive 2014/30/EU, taking into ac-
count the standards EN 61000-6-4 (Emitted interference in
industrial environments) and EN 61000-6-3 (Emitted interfer-
ence in residential environments).
Blowers and side channel blowers with frequency
converter operation (FC):
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.
A CE conformity assessment with the relevant standards and
guidelines must be carried out in all cases before the start-up.
4 INSTRUCTIONS FOR OPERATION
AND USE
4.1 Basic Instructions
Please observe the instructions on the intended use, de-
scribed in 1.1, as well as the safety instructions described
in 1.2 to 1.11.
If the rated current of the drive motor is exceeded during op-
eration, check whether the mains voltage and frequency cor-
respond with the device data.
The device can be restarted only after the cause of the fault
has been identi fi ed and eliminated following surge protec-
tion, such as triggering of the motor protection switch, trig-
gering of the PTC evaluation device with motors fi tted with a
resistor sensor or frequency converter surge protection with
FC applications.
With blowers that cannot be used over the whole character-
istic curve (max. fl ow rate, see rating plate), the motor can
be overloaded if the system resistance is too low (too high
power consumption). Restrict the fl ow rate in this case us-
ing a throttle valve built into the pressure or air intake side.
The blower must not be subjected to any vibration stress or
impact force.
4.2 Frequency Converter Operation
A wide speed setting range is possible using a frequency
converter, whereby there is only a small speed di ff erence be-
tween the idle running and the maximum load of the blower
depending on the load.
