Safety information
2.6 Interference immunity
2.7 Influence on the line power supply through a strongly irregular torque
A strongly irregular torque, for example with the drive of a reciprocating motor, forces a nonsinusoidal motor current. The emerging harmonics can have an impermissible influence on
the line power supply via the connection lines.
2.8 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.
● Comply with the EMC information provided by the manufacturer of the converter. This is
how you prevent the limit values stipulated by IEC/EN 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
● You must put appropriate EMC measures in place.

From January 1, 2017, the IE3 efficiency requirement for motors with a power of 0.75 kW to
375 kW applies for line operation.
Efficiency IE2 still applies for motors that are operated from a converter.
Please note the applicable country-specific rules and regulations.
The rotor assembly is pressed onto the shaft together with the cage winding. The drive end of
the shaft usually has a cylindrical shaft end. Dependent on the design, a second shaft end
may be located at the non-drive end.
The cooling system is designed as a closed, internal cooling circuit. The heat lost from the
machine is dissipated partially via heat conduction and partially via the cooling air at the cooling
water flowing through the cooling pipes. A shaft-mounted fan ensures circulation of the cooling
air.

3.1 Comparison of IEC and GOST (D47) standards
Roller-contact bearings
The machines are equipped with different types of rolling-contact bearings depending on the
version and the operating conditions described in the order. The different types are listed on
the lubricant plate of the machine. In converter operation an insulated bearing is usually
installed on the non-drive end. The following roller-contact bearing variants are available:
Table 3-3 Rolling-contact bearing variants
Version Rolling-contact bearing
Horizontal type of construc‐
tion, coupling output
Vertical type of construc‐
tion, coupling operation
● Drive end: Deep-groove ball bearing as a fixed bearing,
● Non-drive end: Deep-groove ball bearing as a floating bearing with
axial compression springs
● Drive end: Pairing of angular-contact ball bearing / deep-groove ball
bearing as a fixed bearing
● Non-drive end: Deep-groove ball bearing as a floating bearing with
axial compression springs
Rolling-contact bearing design for "Increased degree of protection" (option)
Improved sealing of the bearing units to prevent dust and water from getting in can be achieved
by positioning a grease chamber ahead of the actual bearing unit. Although the same grease
is used in both cases for reasons of convenience, a distinction is made here between
"lubricating grease" and "sealing grease" because of their different functions.
Layout
The spent lubricating grease collects in the space between the bearing housing and the outer
bearing cap. The latter also forms the sealing grease chamber with the labyrinth sealing ring
(optional). The second lubricating nipple containing the grease duct for pressing in the sealing
grease is also located in the outer bearing cap. The chamber is sealed off from the space
where the lubricating grease collects by a V-ring or a V-ring and felt ring combination which
prevents the sealing grease in the chamber from penetrating into the lubricating grease
collecting space. During operation, the sealing grease in the chamber slowly runs out via the
labyrinth and seals it, additionally removing dust from inside and around the outside of the
labyrinth ring.
Terminal box
The terminal box is positioned on the side of the machine. It is fixed to the machine and cannot
be exchanged.
Supplementary devices
Depending on the order, various supplementary devices can be installed or mounted. These
include sensors for bearing temperature monitoring or winding monitoring, for example.

4.10 Phase synchronization during supply system switching
NOTICE
Supply system switching
Damage to the machine may be caused when switching to another supply system with
different phasing.
● The phasing must be synchronized during switching. Use appropriate means to
synchronize the phasing.
4.11 Voltage and frequency fluctuations during line operation
If nothing else is stamped on the nameplate, then the permissible voltage fluctuation is ±5 %
and the permissible frequency fluctuation is ±2 %, corresponding to range A in
IEC / EN 60034‑1. Permissible fluctuations that go beyond this are specified on the nameplate,
e.g. voltage fluctuation of ±10 % corresponding to range B in IEC / EN 60034‑1.
The following applies: Under practical operating conditions a machine may sometimes have
to be operated outside the limits of Range A. Exceptions of this sort should be limited with
regard to the values that arise, how often and for how long they occur. Where possible and
within a reasonable time take corrective actions such as reducing the power. Such actions can
avoid thermal ageing leading to a reduction in the service life of the machine.
NOTICE
Overheating of the winding
Exceeding the permissible tolerances for voltage and frequency can lead to an impermissibly
high temperature rise in the windings and thus cause long-term damage to the machine.

NOTICE
Ground fault during operation on an IT system
If a ground fault occurs when connected to an IT supply system, the insulation is excessively
stressed. Winding damage can result.
● If possible, complete the process within two hours.
● Rectify the fault cause.
● Deploy a ground fault monitoring.
4.15.2 Converter input voltage
The insulation system of SIMOTICS machines significantly exceeds the requirements of stress
category C (IVIC C = high stress). If voltage peaks higher than those specified according to
IVIC C can occur, then observe the data in the respective Catalog (http://w3app.siemens.com/

NOTICE
Material damage caused by an excessively high supply voltage
The insulation system will be damaged if the supply voltage is too high for the insulation
system. This can completely destroy the machine.
● Comply with the peak voltages as laid down in the guidelines above.
4.15.3 Reducing bearing currents
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.
– 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.

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:

5.1.3 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.
Assembly
5.1 Preparations for installation
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.

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 = R

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.

5.2.6 Mounting the output elements
Balance quality
The rotor is dynamically balanced. For shaft extensions with featherkeys, the balancing type
is specified using the following coding on the face of the drive end of the shaft:
● "H" means balancing with a half feather key
● "F" means balancing with a whole feather key.
Figure 5-1 Balancing type on the drive-end side
Pushing on the power output elements
● Prerequisites:
– The coupling and/or the output element must be appropriately dimensioned for the
operating case at hand. The balance quality must satisfy the following requirements.
– 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 using the front thread
holes in the shaft or pulled on by hand.
– 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 with balancing type "H", then you must
machine off the section of feather key protruding from the shaft contour and output element.
Alternatively, ensure that the weights are compensated to achieve the appropriate balance
quality.
● If the transmission element is drawn up on to the shoulder of the shaft, you must ensure
that the part of the coupling groove where the feather key is not inserted is taken into
consideration when balancing the coupling.
The following applies for all 2-pole machines and 4-pole machines with a frequency ≥ 60 Hz:
● The feather key must be shortened if the coupling hub is shorter than the feather key.
● The center of gravity of the coupling half should be within the length of the shaft end.
● The coupling used must be prepared for system balancing.
The number of poles of the machine is specified on the rating plate (in the designation of
the motor type).
Assembly
5.2 Lift the machine to where it will be installed, and position it
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.
● If the machine is to be operated without output elements, secure the feather key on the
free shaft extension so that it cannot be flung out.
● To avoid imbalance, for balancing type "H", reduce the weight of the feather key to 60 %
of the original weight.
5.2.7 Lifting and transporting the machine

WARNING
Inappropriate fastening material
If screws of an incorrect property class have been selected or if they have been fastened to
an incorrect tightening torque, they may break or become loose. This will cause the machine
to move, which could damage the bearings. The rotor could smash into the machine enclosure
and machine parts could be flung out of place. This can result in death, serious injury or
material damage.
● Comply with the required property classes for screwed connections.
● Tighten the screwed connections to the specified tightening torques.
WARNING
Assembly
5.3 Installing the machine
Incorrect alignment
If the machine has not been properly aligned, this will mean the fastening parts are subjected
to stress/distortion. Screws may become loose or break, the machine will move, machine
parts could be flung out of place. This can result in death, serious injury or material damage.
● Carefully align the machine to the driven machine.
NOTICE
Improper handling
Mounting parts such as temperature sensors or speed sensors are attached to the machine
and could be ripped off or destroyed as a result of improper handling. This could lead to
machine malfunctions, extending even to total loss of the machine.
● Where necessary, use suitable steps when performing installation work on the machine.
● Do not stand on cables or attachments during installation. Do not use attachments as
steps.
5.3.2 Selecting fixing screws
● Unless specified otherwise, use mounting bolts with at least strength class 8.8 to ISO 898‑1.
In this way you guarantee that the machine is securely mounted and the forces can be
transferred through the torque.
● Take into account the maximum forces occurring in the case of a fault such as short circuit
or system transfers in phase opposition.

Preconditions for smooth, vibration-free operation:
● Stable foundation design
● Precise alignment of the machine
● Correct balancing of parts to be fitted to the shaft end.
● Maintaining the vibration velocity according to ISO 10816‑3
5.3.4 Aligning the machine to the driven machine and attaching it to it (IM B3 / IM B35)
1. Refer to any instructions for aligning the driven machine and those of the coupling
manufacturer.
2. Align the machines with coupling output to the driven machine in such a manner that the
center lines of the shafts at the operating temperature do not have any parallel or angular
offset. This ensures that no additional forces affect their bearings during operation.
If the thermal change of the motor and the driven machine is different, couple in the cold
state with an appropriate alignment offset. The alignment offset to be set in the cold state
must be determined and specified by the system specialist.
3. For the vertical positioning (x→0), place thin shims over a large surface area under the
machine feet. The number of shims should be kept as low as possible, i.e. stack as few as
possible. This also prevents the machine being subjected to any stress/distortion. Use the
existing tapped holes for the forcing-off bolts to raise the machine.
The balance state of the shaft (full-key or half-key balancing) and alignment errors primarily
influence the service life of the bearing, especially for high motor speeds or when using
rigid couplings.

5.3.5 Aligning the machine to the driven machine and attaching it to it (IM B5)
The standard flange is provided with a centering. The choice of fit for the mating flange on the
driven machine is the system manufacturer's or the plant operator's responsibility.
Note
If the machine is not fitted with a standard flange, align the machine to suit the driven
machine.
Procedure
The machine axis must be horizontal when it is lifted and the flange must be parallel to the
mating flange, so as to avoid seizing and stressing. Otherwise damage to the centering will
result.
1. Grease the centering flange with assembly paste to make the process easier.
2. Screw three studs into tapped holes spaced about 120° apart around the driven machine
flange. The studs act as positioning aids.
3. Position the machine so that its axis is aligned with that of the driven machine, but not yet
quite touching. Advance the machine slowly towards the driven machine; advancing too
quickly risks damaging the centering.
4. If necessary, rotate the machine into the right position so that the clearance holes in the
flange are central to the tapped holes.
5. Move the machine fully up against the mating flange so that it is fully in contact.
6. Fix the machine using the flange fixing bolts, finishing by replacing the studs.
There is a threaded hole M36 at the bottom of the machine where you can fasten the support
base.
● Mount the support base so that no additional mechanical tensions can occur in the housing.
WARNING
Mechanical tensions
The machine may be damaged by additional mechanical tensions in the housing caused
by incorrect mounting of the support base. The machine or machine parts may loosen
during operation.
This can result in death, serious injury or material damage.
● Mount the support base so that no additional mechanical tensions can occur in the
housing.

6.1 Basic rules
The following generally applies to electrical connections:
● Ensure that there is a safe and reliable PE ground connection before starting any work.
● The connecting cables can be sealed and secured at every cable entry point into the
terminal box.
● Lay the connecting cables and in particular the PE conductor in the terminal box in an open
arrangement so that chafing of the cable insulation is prevented.
● Connect the machine in such a way that a permanent, safe electrical connection is
maintained. Avoid protruding wire ends.
● Lay and secure external auxiliary cables separately from the main cable. Elements with
cable ties may be present for this purpose.
● In case of high humidity or when installed outside, water drops can move along the cable
jacket and enter the motor through the cable entry and cable gland.
If you route the cable with an appropriate loop then water doesn't enter the terminal box,
but simply drips off.

6.3 Preparation
6.3.2 Terminal designation
According to IEC / EN 60034‑8, the following basic definitions apply to the terminal
designations for 3-phase machines:
Table 6-1 Terminal designations using the 1U1-1 as an example
1 U 1 - 1 Designation
x Index for pole assignment for pole-changing machines where applicable. A lower
index signifies a lower speed. Special case for split winding.
x Phase designation U, V, W
x Index for winding start (1) or end (2) or if there is more than one connection per
winding
x Additional indices for cases in which it is obligatory to connect parallel power feed
cables to several terminals with otherwise identical designations
6.3.3 Selecting cables
Take the following criteria into account when selecting the connecting cables:
● Rated current
● Rated voltage
● If required, service factor
● System-dependent conditions, such as ambient temperature, routing type, cable crosssection as defined by required length of cable, etc.
● Configuration notes
● Requirements according to IEC/EN 60204‑1
● Dimensioning for bundled cable routing, e.g. according to DIN VDE 0298 Part 4 or
IEC 60364-5-52
6.3.4 Connecting the grounding conductor
The grounding conductor cross-section of the machine must be in full conformance with the
installation specifications, e.g. according to IEC / EN 60204-1.
Table 6-2 Determining the cross-section of the grounding conductor
Cross-section of the line conductor S [mm²] Cross-section of the grounding conductor [mm²]
S > 35 S/2
Grounding connections are located at the struts of the base plate of the stator frame. Hexagon
bolts are located at the marked connection points for the grounding conductor. The grounding
conductor can be connected as follows:
● With stranded cables with cable lugs
● With flat cables with cable end designed accordingly
SIMOTICS TN Series N-compact 1LH8
66 Operating Instructions 06/2017
Page 67
6.4 Introducing and routing the cables
Connecting the grounding conductor
● Ensure that the connecting surface is bare and is protected against corrosion using a
suitable substance, e.g. acid-free Vaseline.
● Locate the flat and spring washers under the bolt head.
● Check that the maximum permissible clamping thickness of 10 mm for the cable lug or strap
is not exceeded.
● Fasten the clamping screw according to the following table.
Bolt Screw-in depth: Tightening torque
M10 x 30 20 mm 52 Nm
● Use the connecting terminals designated for the grounding conductor in the terminal box.
6.3.5 Connecting the machine for a specific direction of rotation
If the machine has one shaft extension or two shaft extensions with different diameters, the
direction of rotation when looking at the front of the single or the thicker shaft extension is
defined as follows:
Electrical connection
● If you connect the power cables in the phase sequence L1, L2, L3 to U, V, W, the resulting
rotation will be clockwise.
● If you interchange two connections, e.g. L1, L2, L3 to W, V, U, the resulting rotation will be
counter-clockwise.
● On machines which are only allowed to run in one direction, the rating plate shows an arrow
which indicates the permitted direction of rotation, and it also specifies the terminal
connections in the required phase sequence.
NOTICE
Incorrect direction of rotation
The machine will not be adequately cooled if it is operated other than how it was originally
ordered or with the incorrect direction of rotation. This can result in machine damage.
Observe the direction of rotation data on the nameplate.
6.4 Introducing and routing the cables
6.4.1 Inserting the cable into the terminal box
The connection cables are inserted into the terminal box via an exchangeable cable entry
plate. The cable entry plate is not drilled by default. This enables you to adapt the number and
size of the boreholes to the rated conditions.
SIMOTICS TN Series N-compact 1LH8
Operating Instructions 06/2017 67
Page 68
Electrical connection
6.4 Introducing and routing the cables
The cable entry plate features a customized design according to the corresponding order.
Insert the cable into the terminal box
1. Unscrew the cable entry plate.
2. Drill the required number of holes or tapped holes in the required size into the cable entry
plate.
3. Fit the required cable glands.
4. Route the cables through the cable glands.
5. Fit the cable entry plate to the terminal box with the assembled cables.
– Lay the cables and in particular the PE conductor in the terminal box in an open
arrangement so that chafing of the cable insulation is prevented.
– Lay and secure external auxiliary cables separately from the main cable. Elements with
cable ties are attached to the floor of the terminal box next to the walls.
6. Connect the ends of the cables to the terminals in accordance with the circuit diagram. The
circuit diagram is located in the cover of the terminal box.
Refer to the "Connecting cables..." section for more information.
6.4.2 Laying cables
● Lay the cables in accordance with IEC/EN 60364-5-52.
● Use EMC cable glands for fixed cables. Screw the EMC cable glands into the threaded
holes in the entry plate, which can be unscrewed.
● Use shielded cables whose shields are conductively connected to a large area of the
terminal box of the motor via EMC cable glands.
● In the case of aluminum connecting bars, insert a steel washer between the cable lug and
the connecting bar. This prevents contact corrosion.
● Arrange the exposed connecting cables in the terminal box so that the PE conductor has
excess length and the insulation of the cable strands cannot be damaged.
● Close off unused bushings with a metal threaded plug. This is the way to achieve a high
frequency-proof shielding.
6.4.3 Connecting cables with cable lugs
1. Select the cable lugs according to the required cable cross-section and fixing screw or stud
size. Information about the maximum cross-section for the respective standard terminal
box design can be found in the catalog.
A sloped/angular arrangement of the supply cables is only permitted provided the required
minimum air clearances are met.
2. Remove the insulation from the conductor ends so that the remaining insulation reaches
almost up to the cable lug ①. Connect only one conductor per cable lug.
SIMOTICS TN Series N-compact 1LH8
68 Operating Instructions 06/2017
Page 69
Electrical connection
6.4 Introducing and routing the cables
3. Fasten the cable lug to the end of the conductor correctly, e.g. by squeezing.
Figure 6-3 Connection with cable lug and fixing screw (schematic diagram)
4. Insulate the cable lug sleeves where necessary to ensure minimum air clearances and the
creepage distance are maintained.
5. Place the cable lug on the terminal support. If you are using a disconnecting link, check its
positioning.
For terminal boxes 1XB7740 and 1XB7750, place the cable lug on the busbar.
6. Tighten the fixing element ② with the corresponding tightening torque:
Fixing element Tightening torque
Fastening screw M12 20 Nm
Fixing screws M16 40 Nm
Fixing nuts M12 20 Nm
6.4.4 Use of aluminum conductors
If you are using aluminum conductors, then comply with the following:
● Use only cable lugs that are suitable for connecting aluminum conductors.
● Immediately before inserting the aluminum conductor, remove the oxide layer from the
contact areas on the conductor and/or the mating piece. Do this using a brush or file.
● Then grease the contact areas immediately using neutral Vaseline. This prevents a new
oxide layer from forming.
NOTICE
Aluminum flow due to contact pressure
Aluminum flows following installation due to the contact pressure. The connection using
clamping nuts can loosen as a result. The contact resistance increases, obstructing the
current from being conducted. This can result in fire and material damage to the machine
– or even in total failure, as well as material damage to the plant or system due to machine
failure.
● Retighten the clamping nuts after approximately 24 hours and then again after
approximately four weeks. Make sure that the terminals are de-energized before you
tighten the nuts.

6.4 Introducing and routing the cables
6.4.5 Using single-stranded cables
NOTICE
High temperatures from induced eddy currents
With high currents and where several single-stranded cables are used instead of multiplestranded cables, high temperatures can result in the cable entry area due to induced eddy
currents. This can result in material damage or even a machine failure.
● After commissioning, ensure that the temperature limits of the connected power cables
are not exceeded during operation. This temperature effect can be reduced by altering
the conditions at the entry points or by using modified cable entry plates after consultation
with the manufacturing plant.
● Use a cable entry plate made of non-ferrous metal.
6.4.6 Internal equipotential bonding
Between terminal box cover and terminal box enclosure, the cover fixing screws serve as
equipotential bonding.
A special external ground conductor is only installed if, for example, flat seals are mounted
without additional support.
When performing any installation work, you must always take care to ensure that all
equipotential bonding measures remain effective.
6.4.7 Stepless mating face for sealing in the terminal box cover (not for GT640)
The sealing face of the terminal box cover is formed by the terminal box enclosure and the
cable entry element. Therefore make sure these parts are correctly aligned, so as to ensure
the seal and hence the degree of protection.
Align the cable entry support and the cable entry plate to the terminal box enclosure so that
the sealing surface between the terminal box and the terminal box cover form a flat face. There
must be no steps in the sealing area.
6.4.8 Minimum air clearances
After proper installation, verify that the minimum air clearances between non-insulated parts
are maintained. Be aware of any protruding wire ends.
Table 6-3 Minimum air clearance dependent on rms value of the alternating voltage U

When determining the required minimum air clearance, the voltage value in the table may be increased
by a factor of 1.1, so that the rated input voltage range is taken into account during general use.
6.5 Connecting the auxiliary circuits
6.5.1 Selecting cables
Take the following criteria into account when selecting the connecting cables for the auxiliary
circuits:
● Rated current
● Rated voltage
Electrical connection
6.5 Connecting the auxiliary circuits
● System-dependent conditions, such as ambient temperature, routing type, cable crosssection as defined by required length of cable, etc.
● Requirements according to IEC/EN 60204‑1
6.5.2 Connecting temperature monitoring for the stator winding
The stator winding is monitored for thermal loading by temperature sensors embedded in the
stator winding.
The connecting cables of the temperature sensors are routed to the main or auxiliary terminal
box, depending on the version. The connection and assignment of the terminals is specified
in the circuit diagram.
WARNING
Hazard due to electric shock
The installation 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”.

7.7 Test run
After installation or inspection, carry out a test run:
1. Start up the machine without a load. To do this, close the circuit breaker and do not switch
off prematurely. Check whether it is running smoothly.
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 down before switching it on again.
2. If the machine is running smoothly and evenly, switch on the cooling equipment. Continue
to observe the machine for a while in no-load operation.

3. If it runs perfectly, connect a load.
NOTICE
Thermal overload of motors connected directly to the line supply
In addition to the load torque, the ramp-up (accelerating) time is essentially influenced by
the moment of inertia to be accelerated. While ramping up when connected to the line
supply, the inrush (starting) current is a multiple of the rated current. This can result in
thermal overload. This can damage the motor.
As a consequence, when ramping up, observe the following:
● Monitor the ramp-up time and number of consecutive starts.
● Comply with the limit values and/or ramp-up conditions specified in the catalog or the
order documentation.

4. During the test run, check and document the following:
– Check whether it is running smoothly.
– Document the voltage, current and power values. As far as possible, document the
corresponding values of the driven machine.
– If this is possible using the available measuring equipment, check the bearing and stator
winding temperatures until they have reached steady-state values.
– Check the machine for noise or vibrations on the bearings or bearing shields as it runs.
5. In case of uneven running or abnormal noise, switch off the machine. As the machine runs
down, identify the cause.
– If the mechanical operation improves immediately after the machine is switched off, then
the cause is magnetic or electrical.
– If the mechanical running does not improve immediately after switching the machine off,
then the cause is mechanical.
- Imbalance of the electrical machine or the driven machine
- The machine set has not been adequately aligned
- The machine is being operated at the system resonance point. System = motor, base
frame, foundation, ...
NOTICE
Serious damage to the machine
If the vibration values in operation are not maintained in accordance with DIN ISO 10816-3,
then the machine can be mechanically destroyed.
● During operation, observe the vibration values in accordance with DIN ISO 10816‑3.
7.8 De-energizing
● If the controller does not do this automatically, switch on any anti-condensation heating
during stoppages. This will avoid the formation of condensation.
● Do not switch on the anti-condensation heating for at least two hours after the motor has
been switched off. This prevents damage to the winding insulation.
● Do not switch off the water-cooling system immediately after switching off the machine.

8.7.1 Avoidance of condensation or formation of condensation within the machine
● If the controller does not do this automatically, switch on any anti-condensation heating
during stoppages. This will avoid the formation of condensation.
● Do not switch on the anti-condensation heating for at least two hours after the motor has
been switched off. This prevents damage to the winding insulation.
8.7.2 Avoidance of frost and corrosion damage in the cooling system
● For avoidance of frost and corrosion damage, completely drain the water from the cooling
system. Then blow air through the cooling system to dry it.
If the cooling system cannot be drained because standby capability is required at short
notice, protect the cooling circuit against frost and corrosion damage. To do this, add
suitable additives to the cooling water.
NOTICE
Impairment of the heat transport
Additives such as anti-freeze and corrosive inhibitor can impair the heat transport.
Operate the motor only with the contractually agreed water quality.
For avoidance of deposits, the cooling water circuit must then be kept running. So as to be
certain of excluding the possibility of formation of condensation within the machine, the anticondensation heating should also remain switched on (if fitted).

8.7.3 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.

With non-encapsulated and non-sealed shaft grounding brushes, rust may form on the
brushes' running surface on the shaft after extended breaks in operation.
WARNING
Live parts
If the shaft grounding does not function correctly, the shaft can be at a high voltage level that
does not decay quickly enough when the machine comes to a standstill. This can lead to
death or serious injury as a result of electric shock, or bearing damage caused by current
flowing through the bearing.
● Regularly inspect the shaft grounding brushes and replace them if necessary.
● Keep the brushes' running surface clean: Regularly inspect the brushes' running surface
and remove any rust before starting the machine up.
8.7.5 Measurement of the insulation resistance after an extended stoppage
