1.7 Temperature
Warning!
The blower housing assumes the temperature of
the conveyed medium during operation. If this is
above +50° C, the blower must be protected
against direct contact by the operator (risk of burn
injury).
In the case of high-power models in particular, the temperature
of the conveyed medium can increase as it fl ows from the intake
side to the exhaust side. The temperature difference can be in
the region of up to +20°C, depending on the operating
conditions. This varies from one model to another.
1.8 Motor circuit breaker
Before putting the blower into operation, be sure to safeguard
the drive motor with a motor circuit-breaker (this does not apply
to frequency-converter-operated appliances).
Where appliances are frequency-converter-operated, the
existing temperature sensor (PTC resistor sensor) must be
connected to the converter and evaluated.
1.9 Noise emission
The noise generated by a blower is not constant throughout the
performance range. For details of radiated noise level, please
refer to the table on page 11.
In some cases, sound insulation may be necessary (it is
recommended that emission levels be measured by the
operator). Sound insulation must be provided by the operator to
avoid exceeding the statutory maximum levels at the workplace
and in the immediate vicinity of the blower.
No sound insulation of any kind whatsoever should cause the
ambient temperature to exceed +40°C at the drive motor (this is
not permissible).
1.10 Electrical hazards
Before carrying out electrical work, the appliance must always be
switched off and protected against accidental restarting.
Check that no voltage is present.

HANDL NG OF THE MACH NE
2.1 Transportation and handling
• Before installation and putting into service, check all
parts for transit damage. A damaged blower is a
potential safety hazard and, therefore, should not be
put into service.
• Do not leave the 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 route of transportation.

3.1 nstallation and assembly
• Install the blower so it is protected against weather
and sun exposure. Refer also to the information on
installation under 1.1, Designated use .
• Do not expose to vibrations or shocks. Permissible
vibrational load on blower: refer to ISO 14 94, BV-3.
• Standard 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.
• Cover open intakes or outlets with protective grating
according to DIN EN ISO 13857.
Warning!
Putting into operation of the incomplete machine
is prohibited until it has been ascertained that the
machine into which the incomplete machine is to
be installed complies with the provisions of the
Machinery Directive (2006/42/EC).
• Ensure adequate motor ventilation. Permissible
ambient temperatures:
Series version with a rated voltage (max. +/-10% voltage
tolerance) and a rated frequency of 50 Hz or 0 Hz:
• Ambient temperature -20°C to + 0°C
Special voltages, multi-voltage motors, FU compatible versions,
FUK versions, UL certifi ed appliances, appliances with
Aircontrol :
• Ambient temperature -20°C to +40°C
• The performance of the drive motor’s ventilation
system must not be impaired by the installation
situation.
3.2 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 threephase
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 operated appliances). Where appliances are
frequencyconverter- 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 confirmed.
• The maximum supply voltage of the
frequency converter is 400 V without a
motor filter. If longer wires and higher
converter supply voltages are used
and/or the max. pulse voltage (1300 Vpp)
at the motor terminals is exceeded,
suitable precautions, e.g. a motor filter,
must be taken to protect the motor.
Please consult the converter supplier in
this matter. If the motor filter is supplied
with the blower, it must be installed
between the converter and the motor.
Please make sure that there is sufficient
reserve space in the switch cabinet and
adhere to the guidelines for installation
and assembly in the operating
instructions issued by the frequency
converter/motor filter manufacturer.
