Operating and assembly instructions SD
• Do not leave the side channel blower unprotected in the
open (protect against ingress of moisture).
• Attach hoist securely. Only use hoists and load suspension
devices with suffi cient load-carrying capacity. Secure the
EN
route of transportation.
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.
• Devices may be stored for a maximum of 2 years.
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
12
or during installation, must be examined by qualifi ed techni-
cians.
• Installation, assembly and operation must only be performed
by properly trained and qualifi ed specialists. Operation fol-
lowing incorrect installation, maintenance or unapproved
replacement of components constitutes non-designated use
and renders the warranty void. The resultant 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 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 specifi cations.
• Blower feet and consoles must be designed only for the
respective blower's own weight.
• 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 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!
Standard equipment 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.

3.3 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 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
confi 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
