• Devices may be stored for a maximum of 2 years.
3 INFORMATION ON COMMISSIONING
EN
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 de
livery or during installation, must be examined by qualifi ed
technicians.
• Installation, assembly and operation must only be
performed by properly trained and qualifi ed specialists.
Operation 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 fulfi ls the requirements listed in 1.1 Intended
Use and protects the side channel blower from the infl 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 must be secured against turning.
• Side channel blower feet and consoles must be designed
only for the respective side channel blower's own weight.

• Cover open intakes or outlets with protective grating
according to DIN EN ISO 13857.
• Ensure that the motor has adequate ventilation.
Permitted ambient temperatures with:
Elektror motor and a rated voltage of 50 Hz or 60 Hz,
Special voltages, multi-voltage motors, FU-compatible
versions, FUK versions, UL-certifi ed devices:
• Ambient temperature -20°C to +40°C
Note!
As per IEC 60038 Elektror motors are generally
designed for an extended voltage range of ±10%.
• The performance of the drive motor's ventilation system
must not be impaired by the installation situation.

• Insert the silencer cartridge (1) in silencer housing (2).
• Adjust the sealing (3) with the in the silencer inserted
screws (4) and fi x it on the side channel blower housing
(5).
3.4 Electrical connection
Note!
The work described in this section may only be
performed by a qualifi 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 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:
• 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 suffi cient space in the
switch cabinet and take into account the installa-
tion and assembly requirements in the operating
