• 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 loadbearing
capacity and avoiding vibration transmission or vibrational
load.
• Standard blowers without base:
At the place of use, bolt the blower securely to a fi xed
base having su ffi cient load capacity without transmitting
vibrations or vibrational load. In the case of HRD blowers
with suction and/ or pressure side connections, this is
possible with the following types:
up to max. HRD 1/5T or HRD 1T FU(K)-105/1,1,
up to max. HRD 14/5T or HRD 14T FU(K)-105/2,2,
up to max. HRD 2/3T or HRD 16T FU(K)-105-2,2 and
up to max. HRD 2T FU(K)-95/3,0.
• Blower units without motor and belt drive belt guard with
these models, the supplied blower base is intended only
for set-up of the blower unit. The purchaser (plant
engineer, operator or other customer) is responsible for
the secure and stable installation and attachment of the
blower in combination with the motor, belt drive and belt
guard to be supplied by the purchaser in compliance with
the applicable standards and regulations.
• Installation of standard blowers with a vertical drive shaft
is possible with HRD blowers up to the following models:
with fl ange housing: maximum to HRD 2/5T
FU/FUK blowers: maximum to HRD 60 FU(K)-105/4,0
• Wall and ceiling mounting is possible up to a maximum of
the following types:
up to max. HRD 1/5T or HRD 1T FU(K)-105/1,1,
up to max. HRD 14/5T or HRD 14T FU(K)-105/2,2,
up to max. HRD 2/3T or HRD 16T FU(K)-105-2,2 and
up to max. HRD 2T FU(K)-95/3,0.
• Other standards and regulations must be observed
depending on the application.
• Blower feet and consoles must be designed only for the
respective blower’s own weight.
• Cover the open air intake and discharge with protective
grilles according to DIN EN ISO 13857.
• Ensure that the motor has adequate ventilation.
Permitted ambient temperatures with:
Standard model with Elektror motor and a rated voltage of
50 Hz or 60 Hz:
• Ambient temperature -20°C to +60°C
Note!
The rated e ffi ciencies and the e ffi ciency classes of
the motors are given as per IEC 60034-2-1 for opera-
tion at an ambient temperature of 25°C. As per IEC
60038 Elektror motors are generally designed for
an extended voltage range of ±10%. However, the
stated e ffi ciency relates to the rated voltage, i.e., the
extended tolerance is not taken into account.
Special voltages, multi-voltage motors, models suitable for
frequency converters, FUK models, devices with UL approv-
al, devices with Aircontrol and other motor makes:
• Ambient temperature -20°C to +40°C
• Voltage tolerance ±5% (For exceptions, see „4.2 Fre-
quency converter operation“)
• The drive motor ventilation system must not be a ff ected by
the installation situation.

3.3 Blower units without motor and belt drive
During assembly of the blower with the motor, belt drive and
belt guard supplied by the purchaser, in addition to the in-
structions given in Chapter 1, the purchaser / operator must
pay attention to the following:
• Exact alignment of the belt pulleys
• Exact axial parallelism of the belt pulley axes
• Correct belt type and belt tension
• Max. permissible forces
• The V-belt pulleys must be free from burrs, rust and dirt
• Correct V-belt pro
fi le and belt pulley type
• Max. permissible blower speeds
You will
fi nd the data relevant to your appliance tabulated in
section 11 and in section 5.4 (where applicable).
3.4 Electrical connection
Note!
The work described in this section may only be
performed by a quali fi ed electrician. Connect the
appliance as per the circuit diagram in the termi-
nal box and in accordance with the relevant local
requirements.
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 operated
appliances). Where appliances are frequency-converter-op-
erated, the existing temperature sensor (PTC resistor sen-
sor) 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!
The following information should also be ob-
served when operating the drive motor with a
frequency converter:
• Only motors must be used on the frequency
converter that are marked on the rating plate with
the option “/FU”, “suitable for use with a frequen-
cy converter” or that were ordered and con fi rmed
as “suitable for use with a frequency converter”.
• The frequency converter supply voltage must
only be a maximum of 400 V without the motor fi l-
ter. Appropriate measures such as a motor fi lter to
protect the motor must be installed on the motor
terminals with higher frequency converter supply
voltages, longer lines 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
