Note!
On devices with in-built frequency converters
(FUK devices):
The frequency converter must never be used to
lift the device or as a climbing aid!

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.
3 INFORMATION ON COMMISSIONING
THE MACHINE

3.1 Installation and assembly

• Protect the blower from the weather and install it in a hori-
zontal position, see also 1.1. For outdoor use, protection
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.

• 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.
• Standard blowers without base:
Bolt securely to a fi rm surface at the 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 RD blowers with an
intake and/or a discharge side connection up to type:
RD 5 or RE 5
• Installation of standard blowers with a vertical drive shaft is
possible with RD blowers up to the following models:
maximum to RD 72.
• Wall and ceiling mounting is possible up to a maximum of
the following types:
maximum RD 5 or RE 5
• 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 effi ciencies and the effi ciency classes
of the motors are given as per IEC 60034-2-1 for
operation 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 effi 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 ap-
proval, devices with Aircontrol and other motor makes:
• Ambient temperature -20°C to +40°C
• Voltage tolerance ±5%
• The drive motor ventilation system must not be affected
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
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 has to be safeguarded by 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) 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!
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 confi 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 lter. Appropriate measures such as a motor fi lter
