3 INFORMATION ON COMMISSIONING
THE MACHINE
EN

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
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 blower from the weather when it is being in-
stalled. 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 u-
ences of the weather.
• Only operate with a horizontal drive shaft.
• Do not subject to any vibration stress or impact force either
during the subsequent operation.
• We recommend the use of expansion joints on ventilation
connections.
• Blowers are subject to international ISO 14694 with regard
to vibration limits.

The category "fl exibly mounted" applies because of the use
of rubber pads.

• Securely screw the device to a fi rm and level subsurface
at the place of operation with suffi cient load-bearing capac-
ity and no vibration transmission/stress.
• After a storage period of 6 months, the blower bearings and
motor bearings should be checked before they are mount-
ed in the blower.
• Cover the open air intake and discharge with protective
grilles according to DIN EN ISO 13857.
• As drive motor a water-cooled electric motor is engaged.
• The motor must not be operated without installed cooling
unit / heat exchanger.
• The following conditions need to be observed:
- The cooling liquid must contain a rustproofi ng additives
- Inlet temperature 10°C - 35°C
- Outlet temperature 40°C
- Flow 1-6 liters/minute
- Pressure 4 bar
• The details on the motor rating plate and the information
from the engine operating manual must be observed.

3.3 Electrical connection

Note!
The work described in this section may only be
performed by a qualifi ed electrician. Connect the
appliance as per the circuit diagram in the termi-
nal box and in accordance with the relevant local
requirements.
We refer specially to the instructions in chapter
"1.5 Speeds"!
As drive motor a motor of the company Emod is engaged
(see instruction manual of the motor).
• For devices operated with a frequency converter, the exist-
ing temperature sensor (PTC resistor sensor) or tempera-
ture gauge (break contact) should be connected and ana-
lysed on the converter.
• Check whether the mains voltage corresponds with the in-
formation on the rating plate.
• The protective earth conductor is 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 maximum supply voltage of the frequency
converter is 400 V without a motor fi lter. If longer
wires and higher converter supply voltages are
used and/or the max. pulse voltage (max. 1000
Vpk for drive motors up to 0.75 kW, maximum
1300 Vpk for drive motors larger than 0.75 kW) at
the motor terminals is exceeded, suitable precau-
tions, e.g. a motor fi lter, must be taken to protect
the motor. Please ensure suffi cient space in the
control cabinet and consider the requirements
for installation and assembly in the operating
manuals 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
additional plug/clamp connections.
