Note!
The HRD 7 FU-120 is supplied as standard with
relubrication units. These should be installed on
the blower before it is started up. More informa-
tion can be found in the enclosed “ Quick Installa-
tion Instructions for Relubrication Units.”
3.3 Electrical connection
Note!
The work described in this section must only be
carried out by a quali fi ed electrician. Carry out
the connection according to the wiring diagram
in the terminal box and the relevant local regula-
tions.
Speci fi cally refer to the information in chapter
“1.5 Speeds.”
Warning!
The maximum speed stamped on the motor rating
plate must never be exceeded in order to prevent
personal injury. Do not operate the blower in the
vibration resonance range (depending on the
respective installation situation).
Please refer for further information about the motor the en-
closed motor instruction manual.
• For devices operated with a frequency converter, the exist-
ing temperature sensor (PTC resistor sensor) or tempera-
ture gauge (break contact) should be connected and ana-
lysed on the converter.
• Check whether the mains voltage corresponds with the in-
formation on the rating plate.
• The protective earth conductor is in the terminal box.
Note!
The following information should also be ob-
served when operating the drive motor with a
frequency converter:
• 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 l-
ter. 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 instructions 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
assembly instructions of the frequency converter supplier.
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 are components that are designed to be in-
stalled 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 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) EN 61000-6-3 (Emitted interference
in residential environments).
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.
