2.2 Storage
• Ensure that the air intake connection and pressure connec-
tion are closed.
• Store the 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 blower bearings
and/or motor bearings should be checked before they are
mounted in the blower.

THE MACHINE
3.1 Installation and assembly
• Protect the blower from the weather and install it in a
horizontal position, see also 1.1. For outdoor use, protec-
tion from the weather must generally be provided that fulfi ls
the requirements listed in 1.1 Intended Use and protects
the blower from the infl uences of the weather.
• Avoid vibrational and impact loads during operation.
Permissible vibrational load on blower:
refer to ISO 14694, BV-3.
Maximum permissible vibration speed
(Limit values according to ISO 14694:2003 (E),
category BV-3)

• Standard blowers with base respectively with bracket:
Bolt securely to a level and fi rm surface at the stationary
place of use, making sure that the surface has adequate
load-bearing capacity and avoiding vibration transmission
or vibrational load.
• Standard blowers without base:
Bolt securely to a fi rm surface at the stationary place of
use, making sure the surface has adequate load-bearing
capacity and avoiding vibration transmission or vibrational
load. This type of installation can be used for S-HE
blowers with an intake and/or a discharge side connection
up to type: S-HE 315 (larger blower types on request).
• Installation of standard blowers with a vertical drive shaft is
possible with S-HE blowers up to the following models:
maximum to S-HE 400.
• Cover the open intake and/or a discharge connection with
wire guards compliant with DIN EN ISO 13857.
• Ensure adequate motor ventilation. Permissible ambient

Standard version with rated voltage (max. +/-10% voltage
tolerance) and a design frequency of 50Hz or 60Hz.
• Ambient temperature -20°C to +40°C
Special voltages, multi-voltage motors, FU compatible
versions, FUK versions, appliances with UL certifi cation,
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 observing the ap-
plicable local regulations.
• The drive motor has to be safeguarded by a motor circuit
breaker (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 to see if the mains voltage matches the voltage
specifi ed on the rating plate.
• 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 rating plate, 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
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
instructions of the frequency converter/motor
fi lter manufacturer.
• The wire running between the motor and the
frequency converter must not exceed a length of
20 m, confi gured as a suitable, shielded cable and
laid by as direct a route as possible, without any
