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.

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.
Star-delta start-up
Motors with ratings of above 3.5 kW are suitable for star-delta
start-up on the mains supply. For direct on-line starting (high
short circuit current at the instant the motor is energised),
please contact your local utility for details of conditions.
3.2.3 Confi guration for single-phase a.c. blowers
3.3 Special confi gurations and additional clamps
Terminal diagrams can be found in the motor terminal box for
voltage interchangeable motors, pole-changeable motors,
FU motors and other special confi gurations of three-phase
a.c. and a.c. motors. This also applies to the optional thermal
winding protection and the space heater.
3.4 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 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 2004/108/EC, taking into ac-
count the standards EN 61000-6-4 (Emitted interference in
industrial environments) and
EN 61000-6-3 (Emitted interference in residential environ-
ments).
Blowers with frequency converter operation (FU):
Prior to the start-up and during operation of the device on a
frequency converter (provided that this is suitable) it is es-
W2 U2 V2
sential that the EMC instructions from the frequency convert-
er manufacturer and the information in the Elektror operating
U1 V1 W1
and assembly instructions are observed in order to meet the
requirements of the EC "Electromagnetic Compatibility" Di-
rective 2004/108/EC.

If the device is delivered together with a frequency converter
package for switch cabinet or wall mounting closer to the mo-
Y circuit
tor, it is possible to comply with EN 61800-3 category C2 (In-
(high voltage)
dustrial environments), taking into consideration the above-
mentioned EMC instructions.
