5.1.3 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.

5.1 Preparing for installation
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 = R
insul 10 min
Many measuring devices display these values automatically following the measurement.

NOTICE
Damage to insulation
If the critical insulation resistance is reached or undershot, this can damage the insulation
and cause voltage flashovers.
● Contact the Service Center (Page 161).
● If the measured value is close to the critical value, you must subsequently check the
insulation resistance at shorter intervals.

Pushing on the power output elements
● Prerequisites:
– The coupling and/or the output element must be appropriately dimensioned for the
operating case at hand.
– Comply with the coupling manufacturer's instructions.
– Make sure that the balancing type of the transmission element correctly matches the
type of balance of the rotor.
– Use only ready drilled and balanced transmission elements. Check the hole diameters
and the balancing status before pulling them on. Thoroughly clean the shaft extension.
● Pulling on:
– Warm up the transmission elements to expand them before pulling them on. Select the
temperature difference for the heating process to suit the coupling diameter, fit and
material. See the coupling manufacturer's instructions.
– Power output elements may only be pushed on or pulled off with the correct equipment.
The output element must be pulled on in one continuous operation via the front thread
holes in the shaft or pulled on by hand.
Mounting
5.2 Lift the machine to where it will be mounted and position it
– Do not strike it with a hammer, as this would damage the bearings.
Shaft extensions with feather key
To maintain the balancing quality, you have the following options:
● If the output element is shorter than the feather key for balancing type "H": Machine off the
section of feather key protruding from the shaft contour and output element in order to
maintain the balance quality.
● If the output element is mounted up to the shaft shoulder for motors with full-key balancing
"F", or if the output element is longer than the motor shaft extension: When balancing the
coupling or the belt pulley, take into account that the feather key does not take up all of the
hub groove.
WARNING
The feather key can fall out
The feather keys are only locked against falling out during shipping. If a machine with two
shaft extensions does not have an output element on one shaft extension, the feather key
can fall out during operation.
Death or serious injury can result.
● Do not operate the machine unless the transmission elements have been pulled on.
● On shaft extensions without output element, take suitable measures to ensure that the
feather key cannot be flung out. For balancing type "H", shorten the feather key by about
half.

5.3.4 Aligning to the driven machine
Vertical and horizontal alignment
The following measures are required in order to compensate any radial offset at the coupling
and to horizontally adjust the motor with respect to the driven machine:
● The contact surfaces of the motor feet must lie on one plane. Place shims under the motor
feet to position it vertically and to prevent any stress/distortion. The number of shims should
be kept as low as possible, so use as few thicker shims as possible, instead of several
thinner shims.
● Shift the motor to the side on the foundation for horizontal positioning. Pay attention to
maintaining the axial position.
● When positioning the motor, ensure that a uniform axial gap is maintained around the
coupling.

WARNING
Risk of electric shock
The insulation of the temperature sensors for the winding monitoring with respect to the
winding is implemented according to the requirements for basic insulation. The temperature
sensor connections are located in terminal boxes, safe to touch - and have no protective
separation. This is the reason that in the case of a fault, a hazardous voltage can be present
at the measuring sensor cable. When touched, this can result in death, severe bodily injury
and material damage.
● When connecting the temperature sensor to external temperature monitoring devices,
when required, apply additional measures to fully comply with the requirements set out in
IEC 60664-1 or IEC 61800-5-1 "Hazard due to electric shock".
6.3.6 Connecting to a converter
Selecting and connecting the cable
● Use Motion Connect cables or symmetrically constructed, shielded cables to connect the
motor to a converter. The cable shielding, made up of as many strands as possible, must
have good electrical conductivity. Braided shields made of copper or aluminum are well
suited.
● The shield is connected at both ends, at the motor and converter. Keep unshielded cable
ends as short as possible.
● In order to ensure that high-frequency currents are efficiently discharged, provide a 360°
contact through a large surface area at the converter and at the motor. Use for instance,
EMC glands at the cable entries.
Measures to reduce bearing currents
To specifically reduce and prevent damage caused by bearing currents, consider the system
as a whole, which comprises the motor, converter, and driven machine. The following
precautions help to prevent bearing currents:
● Setting up a properly meshed grounding system in the system as a whole, with low
impedance for high-frequency currents
● No potential difference between the motor, converter, and working machine.
– Use symmetrical, shielded connecting cables.
– Connect the cable shield at both ends over the greatest possible surface area (360°
contact).
– Use equipotential bonding conductors between the motor and the driven machine as
well as between the motor and the converter
● Limit the voltage rate of rise by using an output filter to dampen harmonic components in
the output voltage

6.3.7 Converter operation on a grounded network
NOTICE
Damage resulting from protective conductor currents
When the machine is operated on a converter with current limiter, but without ground-fault
monitoring, protective conductor currents of up to 1.7 times the external conductor current
can arise if there is a ground fault on the output side. Neither the PE conductors of normally
rated multi-core connecting cables nor the PE connecting points of normal terminal boxes
are suitable for this purpose. Material damage can result.
● Use an appropriately sized PE conductor.
● Connect the PE conductor to the grounding terminal on the motor enclosure.

If the cooling water supply fails or if the motor is operated for a short time without water cooling,
the motor will overheat. This can result in material damage or even a write-off.
Never operate the motor without the cooling water supply switched on. Monitor the
permissible water inlet temperatures.
WARNING
Risk of burning from hot steam
If the cooling water supply fails, the motor will overheat. If cooling water runs into the hot
motor, hot steam suddenly forms, which escapes under high pressure. The cooling water
system can burst. This can result in death, serious injury or material damage.
Do not connect the cooling water supply until the motor has cooled down.
Operation
8.3 Switching on the machine
● After starting the motor, observe it for a while to see if it is running smoothly and check the
monitoring devices.
● Monitor operation and the monitoring devices regularly and record the values you read off.
NOTICE
Speed monitoring
The motor is designed for a certain speed range.
If a motor is operated at impermissible speeds damage to the winding, bearings, or
complete destruction of the motor can be the result.
Ensure that the speeds specified on the rating plate are not exceeded by appropriately
configuring controller and speed monitoring components.

Operation
8.4 Switching off water-cooled motors
NOTICE
Excessive machine temperature
If the anti-condensation heating is operated while the machine is running, this can increase
the temperatures inside the machine. This can result in material damage.
● Make sure that the anti-condensation heating is switched off before the machine is
switched on.
● Only operate anti-condensation heating when the machine is switched off.
8.4 Switching off water-cooled motors
● Switch off the cooling water supply for longer non-operational periods.
● When switching-off, also observe the converter operating instructions.
● If anti-condensation heating is available, switch it on.
8.5 Switching off force-ventilated motors
● Switch off the external fan during longer standstill periods.
Leave the fan on for approximately 30 minutes after switching off the motor to avoid
overheating of the motor.
● Follow the operating instructions of the converter.
8.6 Switching on again after an emergency switching-off
● Check the machine before recommissioning the driven machine after an Emergency Off.
● Eliminate all the causes that have led to the emergency off
8.7 Stoppages
The stoppage is a shutdown for a period of time, during which the machine is stopped but
remains at the location of use.
Under normal ambient conditions, e. g. the stopped machine is not exposed to any vibration,
no increased level of corrosion, etc. in general, the following measures are necessary during
stoppages.

8.8 Decommissioning the machine
Measures for machines ready to operate during longer non-operational periods
● For longer periods when the machine is not being used, either energize it at regular intervals
(roughly once a month), or at least spin the rotor.
● Please refer to the section"Switching on" (Page 91) before switching on to recommission
the motor.
NOTICE
Damage due to improper storage
The machine can be damaged if it is not stored properly. If the motor is out of service for
extended periods of time, implement suitable anti-corrosion, preservation, and drying
measures.
When recommissioning the motor after a long period out of service, carry out the measures
recommended in the chapter entitled "Commissioning (Page 87)".
Operation
8.7.1 Avoidance of damage to roller bearings during stoppages
Extended stoppages at the identical or almost identical resting position of the roller bearings
can lead to damage such as brinelling or corrosion, for example.
● During stoppages, regularly start the machine up for a brief period once a month. As a
minimum, rotate the rotor several times.
If you have uncoupled the machine from the driven machine and secured the rotor with a
rotor shipping brace, then remove this before turning the rotor over or starting the machine
up.
Make sure that the resting position of the roller bearings after the rotor has been turned
over is different from what it previously had been. Use the fitted key or the coupling halves
as reference markers.
● During re-commissioning, refer to the information in the "Commissioning" section.
