Instructions For Operation And Use - Elektror SVD 8 Betriebs- Und Montageanleitung

bus bar. Suitable EMC cable glands must be used
for this on the motor side and also on the INVEOR
EN
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 conformant installation and as-
sembling can be gleaned from the advice in manufacturers' op-
erating and installation instructions for frequency converters.
3.3.1 Circuit for three-phase 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
Briefl y switch on the blower. The impeller's direction of motion
must correspond to the direction arrow on the housing. If the
direction of rotation is wrong, L1 and L3 must be swapped.
Star-delta starting
Motors above 3.0 kW are intended for star-delta starting on
the supply system. For direct switching on (high short-circuit
current at instant of switch-on) please clarify the conditions
with your electricity supply company.

Operating and assembly instructions SVD
3.4 Special circuitry and additional terminals
The terminal boxes for the motors also come with wiring dia-
grams for voltage-selectable motors, pole-changing motors,
FU-series (variable speed) motors and other special circuitry
for three-phase or single-phase a.c. motors. The same ap-
plies for the optional thermal winding protection and standstill
heaters.
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 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 2014/30/EU, 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-
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.
4 INSTRUCTIONS FOR OPERATION
AND USE
4.1 Basic information
Please observe the information on intended use described
in section 1.1, as well as the safety instructions contained in
sections 1.2 through 1.11.
If the rated current of the drive motor is exceeded during op-
eration, check that the supply voltage and frequency match
those stated on the rating plate.
