4.5.3 Types of construction on the rating plate
The type of construction of the machine is stated on the rating plate.
4.5.4 Storage
Storing outdoors
NOTICE
Damage to the motor
Damage can occur if incorrectly stored.
Take all precautions to protect the motor under extreme climatic conditions, e.g. salt-laden
and/or dusty, moist/humid atmospheres.
Choose a dry storage location which is safe from flooding and free from vibration. Repair any
damage to the packaging before putting the equipment into storage if this is necessary to
ensure proper storage conditions. In order to ensure protection against ground moisture, locate
machines, equipment and crates on pallets, wooden beams or foundations. Prevent equipment
from sinking into the ground. Do not impede air circulation under the stored items.
Covers or tarpaulins used to protect the equipment against the weather must not come into
contact with the surfaces of the equipment. Use wooden spacer elements to ensure that air
can circulate freely around the equipment.
Storing indoors
The storage rooms must provide protection against extreme weather conditions. They must
be dry, free from dust, frost and vibration and well ventilated.
Bare metal surfaces
For transport, the bare surfaces (shaft ends, flange surfaces, centering edges) should be
coated with an anti-corrosion agent which will last for a limited amount of time (<6 months).
Apply suitable anti-corrosion measures for longer storage times.
Condensation drain hole
Open any condensation drain holes to drain the condensation depending on the environmental
conditions, every six months at the latest.
Preparing for use
4.5 Transport and storage
Smoke extraction motors
Compact Operating Instructions, 03/2016, 56108000040019 21
4.6 Bearing lifetime
Storage temperature
Permissible temperature range: -20 °C to +50 °C
Maximum permissible air humidity: 60%
For machines that have a special design regarding the coolant temperature in the operating
state or the installation altitude, other conditions could apply regarding the storage
temperature. In this case, refer to the machine rating plate for data on the coolant temperature
and installation altitude.
Storage time
Turn the shaft once every year to avoid bearing brinelling. Prolonged storage periods reduce
the useful life of the bearing grease (aging).
Open bearings
● For open bearings, e.g. 1Z, check the status of the grease when stored for longer than 12
months.
● Replace the grease if it is identified that the grease has lost its lubricating properties or is
polluted. The consistency of the grease will change if condensation is allowed to enter.
Closed bearings
● For closed bearings, replace the DE and NDE bearings after a storage time of 48 months.
NOTICE
Storage
The motor can be damaged if you use it or store it unprotected outdoors.
● Protect the motor against intensive solar radiation, rain, snow, ice and dust. Use a
superstructure or additional cover, for example.
● If required, contact the Siemens Service Center, or technically coordinate outdoors use.
Note
If the torque levels are very unequal (e.g. when a reciprocating compressor is being driven),
a non-sinusoidal machine current will be induced whose harmonics can have an impermissible
effect on the supply system and cause impermissible interference emissions as a result.
Preparing for use
4.6 Bearing lifetime
Smoke extraction motors
22 Compact Operating Instructions, 03/2016, 56108000040019
Note
Converter
● If operated with a frequency converter, the emitted interference varies in strength,
depending on the design of the converter (type, interference suppression measures,
manufacturer).
● Avoid that the specified limit values stipulated for the drive system (consisting of the motor
and converter) are exceeded.
● You must observe the EMC information from the manufacturer of the converter.
● The most effective method of shielding is to conductively connect a shielded machine
supply cable to the metal terminal box of the machine (with a metal screw connection) over
a large surface area.
● On machines with integrated sensors (e.g. PTC thermistors), disturbance voltages caused
by the converter may occur on the sensor cable.
4.7 Converter operation
4.7.1 Parameterizing the converter
● If the design of the motor requires connection to a particular converter type, the rating plate
will contain corresponding additional information.
● Correctly parameterize the converter. Parameterizing data can be taken from the machine
rating plate (not the supplementary rating plate with the operating data when connected to
a converter).
You can find parameter data here:
– In the operating instructions for the converter.

4.7.2 Reducing bearing currents during operation with converter (low voltage)
Taking the following actions will reduce the bearing currents:
● Ensure that the contacts are established over a large area. Solid copper cables are not
suitable for high frequency grounding because of the skin effect.
Equipotential bonding conductors:
Use equipotential bonding conductors:
● Between motor and driven machine
● Between motor and converter
● Between the terminal box and the RF grounding point at the motor enclosure.
Selecting and connecting the cable:
As far as possible, use symmetrically arranged, shielded connection cables. The cable
shielding, made up of as many strands as possible, must have good electrical conductivity.
Braided shields made of copper or aluminum are very suitable.
● The shield is connected at both ends, at the motor and converter.
● To ensure good discharging of high-frequency currents, provide contacting over a large
surface area:
– as contact established through 360° at the converter
– at the motor, for instance with EMC glands at the cable entries
● If the cable shield is connected as described, then it ensures the specified equipotential
bonding between the motor enclosure and converter. A separate RF equipotential bonding
conductor is then not necessary.

Concentric copper or aluminum shield Steel armor
● If the cable shield is not connected due to special secondary conditions, or not adequately
connected, then the specified equipotential bonding is not provided. In this particular case,
use a separate RF equipotential bonding conductor:
– Between the motor enclosure and protective ground rail of the converter.
– Between motor enclosure and driven machine
– Use braided flat copper straps or high-frequency cables with finely-stranded conductors
for the separate RF equipotential bonding cable. Solid copper cables are not suitable
for high frequency grounding because of the skin effect.
– Ensure that the contacts are established over a large area.

Overall system design
To specifically reduce bearing currents, you must consider the system as a whole, which
comprises the motor, converter, and driven machine. The following measures support you
when reducing bearing currents and help to avoid damage:
● In the overall system, set up a properly meshed grounding system with low impedance.
● Use the common-mode filter (damping cores) at the converter output. The Siemens sales
representative is responsible for selection and dimensioning.
● Limit the rise in voltage by using output filters. Output filters dampen the harmonic content
in the output voltage.

load.
5.3.3 Insulation resistance
5.3.3.1 Insulation resistance and polarization index
Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
● Before starting up a machine for the first time
● After an extended period in storage or downtime
● Within the scope of maintenance work
The following information is provided regarding the state of the winding insulation:
● Is the winding head insulation conductively contaminated?
● Has the winding insulation absorbed moisture?
As such, you can determine whether the machine needs commissioning or any necessary
measures such as cleaning and/or drying the winding:
● Can the machine be put into operation?
● Must the windings be cleaned or dried?
Detailed information on testing and the limit values can be found here:

5.3.3.2 Testing the insulation resistance and polarization index
WARNING
Hazardous voltage at the terminals
During and immediately after measuring the insulation resistance or the polarization index
(PI) of the stator winding, hazardous voltages may be present at some of the terminals.
Contact with these can result in death, serious injury or material damage.
● If any power cables are connected, check to make sure line supply voltage cannot be
delivered.
● Discharge the winding after measurement until the risk is eliminated, e.g. using the
following measures:
– Connect the terminals with the ground potential until the recharge voltage drops to a
non-hazardous level
– Attach the connection cable.
Measure the insulation resistance
1. Before you begin measuring the insulation resistance, please read the operating manual
for the insulation resistance meter you are going to use.
2. Make sure that no power cables are connected.
3. Measure the winding temperature and the insulation resistance of the winding in relation
to the machine enclosure. The winding temperature should not exceed 40° C during the
measurement. Convert the measured insulation resistances in accordance with the formula
to the reference temperature of 40° C. This thereby ensures that the minimum values
specified can be compared.
4. Read out the insulation resistance one minute after applying the measuring voltage.
Limit values for the stator winding insulation resistance
The following table specifies the measuring voltage and limit values for the insulation
resistance. These values correspond to IEEE 43‑2000 recommendations.

Conversion to the reference temperature
When measuring with winding temperatures other than 40° C, convert the measuring value to
the reference temperature of 40° C according to the following equations from IEEE 43-2000.
(1)
RC = KT · RT
RCInsulation resistance converted to 40° C reference temperature

(2)
KT = (0.5) (40-T)/10
40 Reference temperature in °C
10 Halving/doubling of the insulation resistance with 10 K
T Measuring/winding temperature in °C
In this case, doubling or halving the insulation resistance at a temperature change of 10 K is
used as the basis.
● The insulation resistance halves every time the temperature rises by 10 K.
● The resistance doubles every time the temperature falls by 10 K.
For a winding temperature of approx. 25° C, the minimum insulation resistances are 20 MΩ
(U ≤ 1000 V) or 300 MΩ (U > 1000 V). The values apply for the complete winding to ground.
Twice the minimum values apply to the measurement of individual assemblies.
● Dry, new windings have an insulation resistance of between 100 and 2000 MΩ, or possibly
even higher values. An insulation resistance value close to the minimum value could be
due to moisture and/or dirt accumulation. The size of the winding, the rated voltage and
other characteristics affect the insulation resistance and may need to be taken into account
when determining measures.
● Over its operating lifetime, the motor winding insulation resistance can drop due to ambient
and operational influences. Calculate the critical insulation resistance value depending on
the rated voltage by multiplying the rated voltage (kV) by the specific critical resistance
value. Convert the value for the current winding temperature at the time of measurement,
see above table.
Measuring the polarization index
1. To determine the polarization index, measure the insulation resistances after one minute
and ten minutes.
2. Express the measured values as a ratio:
PI = Rinsul 10 min / Rinsul 1 min
Many measuring devices display these values automatically following the measurement.
For insulation resistances > 5000 MΩ, the measurement of the PI is no longer meaningful and
consequently not included in the assessment.

Measures for start-up
After installation or inspections, the following measures are recommended for normal start-up
of the machines:
● Start the machine without a load. To do this, close the circuit breaker and do not switch the
machine off prematurely. Switching the machine off again while it is starting up and still
running at slow speed should be kept to a bare minimum, for example for checking the
direction of rotation or for checking in general. Allow the machine to run to a standstill before
switching it back on again.
● Check mechanical operation for noise or vibration at the bearings or end shields.
● If the machine is not running smoothly or is emitting abnormal noises, switch it off, and
determine the cause of the fault as it runs down.
● If mechanical operation improves immediately after the machine is switched off, then the
cause is magnetic or electrical, e.g. voltage imbalance, magnetic imbalance. If mechanical
operation does not improve immediately after switching the machine off, then the cause is
mechanical, e.g. an imbalance in the electrical machines or in the driven machine,
inadequate alignment of the machine set, operation of the machine with the system
resonating (system = machine + base frame + foundations etc.).
● If the machine runs perfectly in terms of its mechanical operation, switch on any cooling
devices present and continue to monitor the machine for a while as it idles.
● If it runs perfectly, connect a load. Check that it runs smoothly.
Read off and document the values for voltage, current, and power.
Where possible, read off corresponding values for the driven machine and document them
as well.
● Monitor the bearing temperature, winding temperature, etc. until the system reaches a
steady state.
Document these, provided this is possible with existing measuring instruments.

9.4.2 Re-greasing
For machines with regreasing system, relubrication intervals, grease quantity and grease
grade are provided on the lubricant plate. Additional data can be taken from the main machine
rating plate.
Grade of grease for standard motors (IP55) UNIREX N3 - ESSO.
Note
It is not permissible to mix different types of grease.
Prolonged storage periods reduce the useful lifetime of the bearing grease. Check the condition
of the grease if the equipment has been in storage for more than 12 months. If the grease is
found to have lost oil content or to be contaminated, the machine must be immediately
relubricated before commissioning. For information on permanently-greased bearings, please
refer to the section titled Bearings (Page 57).
Procedure
To relubricate the roller bearings, proceed as follows:
1. Clean the grease nipples at the drive end and non-drive end.
2. Press-in the specified grease and amount of grease according to the data stamped on the
lubrication plate.
– Please observe the information on the rating and lubricant plates.
– Regreasing should be carried out when the motor is running (max. 3600 rpm).
The bearing temperature can rise significantly at first, and then drops to the normal value again
when the excess grease is displaced out of the bearing.
NOTICE
This invalidates the warranty and operational safety
Mixing different types of grease can lead to material damage on the machine.
If you use or mix types of grease other than UNIREX N3, this invalidates the warranty and
standard conformity with the EN 12101-3 test standard.
Only use UNIREX N3 for re-lubrication purposes.
