5 safety rules
1. Disconnect the system.
Also disconnect the auxiliary circuits, for example, anti-condensation heating.
2. Secure against reconnection.
3. Verify absence of operating voltage.
4. Ground and short-circuit.
5. Provide protection against adjacent live parts.
To energize the system, apply the measures in reverse order.
Qualified personnel
Ensure that only qualified personnel in the sense of these operating instructions work
at the machine or close to the machine.
Danger as a result of stationary parts under voltage (live parts)
Live parts represent a hazard. Touch protection against active (live) parts is no
longer guaranteed if covers are removed. The minimum air and creepage distances
may be fallen below (violated) when coming close to active parts. Touching or
coming close can result in death, serious injury or material damage.
● Carefully ensure that all of the covers are closed while operational.
● First switch off and disconnect the machine if you must remove covers. Carefully
comply with the "Five safety rules " (Page 1).
● In operation, the terminal box must always be kept closed. It is only permissible to
open the terminal box when the motor is stationary and in a no voltage condition.
Risk of injury due to rotating parts
Rotating parts are dangerous. Touch protection against rotating parts is no longer
guaranteed if covers are removed. Touching rotating parts can result in death,
serious injury or material damage.
● Carefully ensure that all of the covers are closed while operational.
● First switch off and disconnect the machine if you must remove covers. Comply
with the "Five safety rules":
● Only remove the covers when the rotating parts have come to a complete
standstill.

Risk of burn injuries as a result of hot surfaces
Individual machine parts can become hot in operation. Burns can result when coming
into contact with these parts.
● Never touch machine parts during operation.
● Allow the machine to cool down before starting work.
● Check the temperature of parts before touching them. If required, wear suitable
protective equipment.
Faults in operation
Any changes with respect to the normal condition can indicate that the machine is not
functioning correctly.
● Higher power consumption, temperatures or vibration levels.
● Unusual noise or smells.
● Monitoring devices respond.
This can cause faults which can result in eventual or immediate death, serious injury
or material damage.
● Immediately inform the service personnel.
● If you are in doubt, immediately switch off the machine, carefully observing the
system-specific safety conditions.
Damage caused by condensation
Humidity in the air can condense for intermittent duty or load fluctuations.
Condensate can collect. Moisture can have a negative impact on the winding
insulation or result in damage, such as corrosion.
● Ensure that any condensation can freely flow away.
Hazardous substances
Chemical substances required for the setup, operation and maintenance of machines
can present a health risk. Poisoning, skin damage, cauterization of the respiratory
tract, and other health damage may result.
● Read the information in these operating instructions and the product information
supplied by the manufacturer.
● Observe the relevant safety regulations and wear the personal protective
equipment specified.
Preparing for use, transport and storage

Substances that can be easily ignited and are flammable
Chemical substances required for the setup, operation and maintenance of machines
may be flammable. Burns and other damage to health and material may result.
● Read the information in these operating instructions and the product information
supplied by the manufacturer.
● Observe the relevant safety regulations and wear the personal protective
equipment specified.
Preparing for use, transport and storage
Preconditions for safe lifting and transporting
If you do not transport or lift the machine in a position appropriate for its construction,
the machine can tip, slip into the lifting equipment or fall down. This can result in
death, serious injury or material damage.
● Use only the load carrying device on the stator frame for lifting.
● Use the load carrying device appropriate for the machine position.
● Only use suitable rope guiding or spreading devices.
Center of gravity not centered
If the center of gravity of a load is not located centrally between the attachment
points, the machine can tip over or slip out of the lifting equipment and fall when it is
being transported or lifted. This can result in death, serious injury or material
damage.
● Comply with the handling instructions on the machine when transporting it.
● Be aware of the possibility of different loads on the sling ropes or lifting straps and
the carrying capacity of the lifting equipment.
● Always take account of the center of gravity when transporting or lifting the
machine. If the center of gravity is not located centrally between the attachment
points, then position the hoisting hook above the center of gravity.
Risk of dropping and swinging when transported suspended
If you transport the motor suspended from cables or ropes, the cables or ropes can
break, e.g. as a result of damage. Further, if not adequately attached, the motor can
swing. This can result in death, serious injury, or material damage.
● Use additional, suitable lifting equipment for transport and during installation.
● Two cables alone must be able to carry the complete load.
● Prevent the lifting equipment from sliding by appropriately securing it.
Mounting
Safety instructions for SH 63 ... 355
A5E43215508A, 06/2018 5
● When using 2-cable lifting equipment, ensure that the maximum angle of
inclination is ≤45° according to ISO 3266 (DIN 580).
● Align the eyebolts so that the cables used for lifting are aligned with the planes of
the eyebolts.
Toppling over or slipping of the motor
The motor can slide or topple over if it is not correctly lifted or transported. This can
result in death, serious injury, or material damage.
● Use all the lifting eyes on the machine.
● When using the lifting eyes on the machine, do not attach any additional loads or
weight. The lifting eyes are only designed for the weight of the machine itself.
● Any eyes that are screwed in must be tightly fastened.
● Eyebolts must be screwed in right up to their supporting surface.
● Comply with the permissible eyebolt loads.
● When necessary, use suitably dimensioned lifting equipment, for example
hoisting straps (EN1492-1) and load restraints (EN12195-2).
Mounting
Injury and material damage caused by 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.
Injury and material damage caused by incorrect machine 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.
Electrical connection
Safety instructions for SH 63 ... 355
6 A5E43215508A, 06/2018
Material damage caused by 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.
Electrical connection
Material damage as a result of connection parts coming loose
If you use fixing elements made from the wrong material or apply the wrong
tightening torque, this could impair current transfer or cause connecting parts to
become loose. This could result in material damage to the machine or even in total
failure, which could in turn lead indirectly to material damage to the system.
● Tighten the screwed connections to the specified tightening torques.
● Observe any specifications regarding the materials from which fixing elements
must be made.
● When performing servicing, check the fastenings.
