Note!
The eye bolt on the motor must not be used to
lift the entire blower. This is unsed if the motor
needs to be (dis-)assembled.
2.2 Storage
• Ensure that the air intake connection and pressure
connection are closed.
• Store the side channel blower
-> in its original packaging if possible
-> in a closed room
-> in a dry, dust-free and vibration-free area.
• Storage temperature range from -20°C to +60°C
• After a storage period of 6 months, the bearings should
be checked before they are mounted in the side channel
blower.
3 INFORMATION ON COMMISSIONING
THE MACHINE
3.1 Basic information
• Prior to the
fi
rst start-up and before any other start-up, the
proper operating status of the unit must be inspected. Units
that, for example, are found to be defective upon delivery
or during installation, must be examined by quali
fi
ed tech-
nicians.
• Installation, assembly and operation must only be per-
formed by properly trained and quali
fi
ed specialists. Op-
eration following incorrect installation, maintenance or
unapproved replacement of components constitutes non-
designated use and renders the warranty void. The result-
ant risk shall be borne solely by the customer or owner.
3.2 Installation and assembly
• Protect the side channel blower from the weather and
install it in a horizontal position - see also 1.1. For outdoor
use, protection from the weather must generally be pro-
vided that ful
fi
ls the requirements listed in 1.1 Intended
Use and protects the side channel blower from the in
fl
u-
ences of the weather.
• Do not expose to vibrations or shocks. Permissible
vibrational load on side channel blower: refer to ISO
14694, BV-3.
• Standard side channel blowers with base: Bolt securely
to a level and
fi
rm surface at the place of use, making
sure that the surface has adequate load-bearing capacity
and avoiding vibration transmission or vibrational load.
• Side channel blowers placed on the rubber elements
provided must be secured against turning.
• Blowers with motor (drive), belt drive and belt guard: The
buyer (plant manufacturer, operating company or other
customer) is solely responsible for safe, stable installation
and fastening in conjunction with the motor, belt drive and
belt guard to be provided by the customer, and for compli-
ance with applicable standards and speci
fi
cations.
• Cover open intakes or outlets with protective grating
according to DIN EN ISO 13857.
• The belt drive and rotating parts must be covered with a
belt guard according to DIN EN ISO 13857.
• Ensure adequate motor ventilation. Permissible ambient
temperatures:
Special voltages, multi-voltage motors, FU compatible ver-
sions, FUK versions, UL certi
fi
ed appliances:
• Ambient temperature -20°C to +40°C
• The performance of the drive motor’s ventilation system
must not be impaired by the installation situation.
3.3 Electrical connection
Note!
The work described in this section may only be
performed by a quali
fi
ed electrician. Connect the
appliance to the power supply in the terminal box
as per the wiring diagram and in compliance with
the applicable local regulations.
Three-phase or a.c. motors can be used as drive motors.
In the appliance designation, the letter D stands for three-
phase a.c. and the letter E for single-phase a.c.
• The drive motor must be protected using a motor overload
switch (this does not apply to frequency converter oper-
ated appliances). Where appliances are frequency-
converter-operated, the existing temperature sensor
(PTC resistor sensor) or temperature switch (normally
closed contact) must be connected to the converter and
evaluated.
• Check that the mains voltage matches the ratings on
the nameplate.
• The safety earth terminal can be found in the terminal box.
Note!
For operation of the drive motor with a frequency
converter, the following points should also be
noted:
• Motors may only be operated on a frequency
converter if they have “/FU” (which denotes
“frequency converter compatible”) marked on
the nameplate, or if they have been ordered as
“frequency converter compatible” motors and
con
fi
rmed.
• 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 longer cables, higher
frequency converter supply voltages 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 suf
fi
cient space in the
switch cabinet and take into account the installa-
tion and assembly requirements in the operating
instructions of the frequency converter/motor
fi
lter manufacturer.
• The wire running between the motor and the
