Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.

Safety information
2.5 Interference voltages when operating the converter
Smoke extraction motors
14 Operating Instructions, 03/2016, 5 610 80000 40 018
2.5
Interference voltages when operating the converter
WARNING
Interference voltages when operating the converter
When a converter is in operation, the emitted interference varies in strength depending on
the converter (manufacturer, type, interference suppression measures undertaken). On
machines with integrated sensors (e.g. PTC thermistors), interference voltages caused by
the converter may occur on the sensor lead. This can cause faults which can result in
eventual or immediate death, serious injury or material damage.
Observe the EMC instructions of the converter manufacturer in order to avoid exceeding
the limit values according to IEC/EN 61000-6-3 for drive systems comprising machine and
converter. You must put appropriate EMC measures in place.
2.6
Special designs and construction versions
Note
Before carry out any work on the machine, determine the machine version.
If there are any deviations or uncertainty, contact the manufacturer, specifying the type
designation and serial number (see the rating plate
), or contact the Siemens Service Center.

3.1
Area of application
The three-phase machines of this series are used as industrial drives. They are designed for
operation in automatic smoke and heat extraction units according to EN12101-3. These
motors are designed for operation under normal and fault conditions when a fire occurs, i.e.
they have a dual function.
They are characterized by their high power density, ruggedness, long lifetime, and overall
reliability.
Intended use of the machines
These machines are intended for industrial installations. They comply with the harmonized
standards of the series EN / IEC 60034 (VDE 0530). It is prohibited to use these motors in
hazardous zones if the marking on the rating plate does not explicitly permit line or converter
operation. If other/more wide-ranging demands (e.g. protection so that they cannot be
touched by children) are made in special cases – i.e. use in non-industrial installations –
these conditions must be ensured by the customer.
Note
Machine directive
Low
-voltage motors are components designed for installation in machines in accordance
with the current Machinery Directive. Commissioning is prohibited until it has been absolutely
identified that the end product is in
conformance with this Directive. Please observe the
EN
60204-1 standard.
3.1.1
Operating UL-certified machines with a converter
Note
Operating a machine with a converter
Implement all machines of the overall machine
-converter system according to UL-File
E227215 assuming that the machines are only to be operated with a converter and are
supplied with UL certificate.
The company operating the equipment is responsible for implementing this in the actual
application.

CE marking
Note
Use of machines without CE identification
Machines without
marking are intended for operation outside the European Economic
Area (EEA). Do not use any machines without CE mark within
of the EEA!
3.1.3
IE2 marking
Note
IE2 marking
Since January 1, 2015, according to REGULATION (EC) No. 640/2009, low
-voltage motors
with power ratings above 7.5
kW up to 375 kW – and with efficiency IE2 – have this label.
This is mandatory within the European Economic Area (EEA). Customers are solely
responsible in ensuring the correct use.
When connecting the machine to a converter, carefully observe the rules a
nd notes in
Chapter "Connecting a converter."

3.3.1
Machine design
Machines of this series are low-voltage three-phase asynchronous drives with a cylindrical
shaft extension and featherkey way. They can be supplied as single-speed machines with
different efficiency classes or as pole changing machines for several speeds.
In the case of machines with feet (IM B3 type of construction), the feet are cast or bolted on.
It is possible to change over the bolted on mounting feet on the machine enclosure, for
example to change the terminal box position; only authorized retrofit partners may carry out
this work.

3.3.3
Cooling and ventilation
The machines of this series are three-phase asynchronous machines with a closed primary
(internal) cooling circuit and an open secondary cooling circuit (surface cooling). The surface
cooling varies depending on the version.
3.3.3.1
Machines with a fan
Self-ventilation (standard): Cooling IC 411 in accordance with EN / IEC 60034-6
Located at the ND end of the stator housing is an air intake cowl that guides the external air
on its way to the motor. The external air is drawn in through openings in the air intake cowl
and flows axially across the outer cooling ribs of the motor frame. The fan wheel for the
external flow of cooling air is attached to the machine shaft.
The fan wheels are bidirectional.
Check the cooling effect below rated speed in the case of frequent switching or braking – or
if the speed is controlled continually below the rated speed.
The motors have a metal fan.

Machines without a fan (optional)
Surface cooling by relative movement of cooling air: Type of cooling IC 418 in accordance with

3.3.4
Bearings
In order to support the machine shaft and maintain its position in the non-moving part of the
machine, only 2 rolling-contact bearings are used. One roller bearing performs the function
of a location bearing that transfers axial and radial forces from the rotating machine shaft to
the non-moving part of the machine. The second roller bearing is implemented as floating
and support bearing in order to allow thermal expansion inside the machine and transfer
radial forces.
The nominal (calculated) useful life of the bearings according to ISO 281 is at least 20,000
hours with utilization of the permissible radial/axial forces. However, the achievable useful
life of the bearings can be significantly longer in the case of lower forces (e.g. operation with
self-aligning couplings).
Roller bearings with permanent lubrication are maintenance-free.

3.3.5
Balancing
As standard, the motor is balanced dynamically with a half featherkey (code "H") in
accordance with ISO 8821.
The balance quality corresponds to vibration level "A". Vibration level "B" is optional or
possible on request.
