WARNING
Always transport and lift the motor on the lifting eyebolts
If you lift the motor by the cooling water pipe system, the pipes will be damaged and the
motor might be dropped. Death, serious injury, or material damage to the motor - even a
write-off - can result.
Do not attach the motor at the cooling water pipes when you have removed the bearing
end shields. The bearing end shields must always be mounted when you transport the
motor.
There are two lifting eyebolts for horizontal transport of the motor. In addition there are
two threads for vertical lifting with the shaft end pointing downwards. For this, the lifting
eyebolts and the threaded plugs have to be swapped around.
Only lift the motor at the lifting eyebolts on the bearing end shields. To hoist the motor,
in particular if there are built-on assemblies, use suitable cable-guidance or spreading
equipment.
Pay attention to the lifting capacity of the hoisting gear. The weight of the motor is
specified on the rating plate (Page 17).

CAUTION
Seizure damage to bearings
If the motors are stored incorrectly there is a risk of bearing seizure damage such as
brinelling, for example as a result of vibrations.
Read the following storage instructions.
Preparation
● Fit the rotor shipping brace.
● Apply a preserving agent such as Tectyl to bare external components such as shaft ends,
if this has not already been applied in the factory.
Storing indoors
CAUTION
Damage caused as a result of outdoor storage
Storing the machine outdoors can result in it being damaged. Ensure that the machine is
only stored in areas that comply with the following conditions.
● Store the motor in an area that meets the following criteria:
– Dry, dust-free, frost-free and vibration-free The relative air humidity should be lower
than 60% and the temperature should not drop below -15 °C in accordance with
EN 60034-1.
– Well ventilated
– Offers protection against extreme weather conditions
– The air in the storage area must not contain any harmful gases.
● Protect the motor from shocks and humidity.
● Cover the motor properly.
● Avoid contact corrosion:

Protection against humidity
● If a dry storage area is not available, then take the following precautions:
– Wrap the motor in humidity-absorbent material and then wrap it in film to create an air-
tight unit.
– Include several bags of desiccant in the seal-tight packaging. Check the desiccant and
replace as required.
– Place a humidity meter in the seal-tight packaging to indicate the level of air humidity
inside it.
– Inspect the motor regularly.
Long-term storage
If you are storing a machine for more than six months, you must check its condition every six
months.
● Check the machine for damage.
● Carry out any necessary maintenance work.
● Document all preservation measures taken so that they can be reversed before the
machines are put back into service.
● Provide air-conditioning for the storage room.
Condensation
Condensation can collect in the machine as a result of sharp fluctuations in ambient
temperature, exposure to direct sunlight, high levels of humidity in the storage location or
intermittent operation/variations in load during operation.
CAUTION
Damage caused by condensation
If the stator winding gets damp, its insulation resistance decreases. This results in voltage
flashovers, which can destroy the winding. Condensation can also cause rusting inside the
machine.
In the bearing shields at the DE and NDE, water drain holes are situated in the foot area and
opposite the regreasing system. Make sure that the condensation can always drain away
freely.
Note
In IM B3, IM B5, IM B35 types of construction, water drainage holes are only functional in
horizontal installations.

4.2.3 Protecting the cooling-water system
When the units are delivered, the high-grade steel cooling-water pipe system is not filled with
cooling water.
● When you put the motor into storage after use, drain the cooling water ducts and purge
with air to ensure that they are completely empty.
● For operation, add a maximum of 20 % to 30 % of an anti-freeze agent to the cooling
water; use Antrifrogen N or Tyfocor, for example, as the anti-freeze.
CAUTION
Frost damage to the cooling circuit
Damage may be caused to the cooling circuit if the cooling water freezes.
If the ambient temperature falls below 0 °C during operation add anti-freeze to the
cooling water.
